     The image capturing apparatus  100  may be such as a digital still camera and a camera cell-phone. Additionally the image capturing apparatus  100  may have a function for outputting images or sounds as well as the output apparatus  140 . The image capturing apparatus  100  may record image and sound data on a recording medium and the output apparatus  140  may receive the data from the recording medium to output the image and sound. Further, the image capturing apparatus  100  may store the directories associated with the directories provided for each user  180  in a server connected to the communication line  150 , such as the directories associated with the image capturing apparatus  100 . Then, the output apparatus  140  may receive the image and sound data stored in the server for each user  180 . 
     The image capturing apparatus  100  extracts objects such as a dog and a bird shown on the captured image and identifies the kind of the extracted object. Then, the image capturing apparatus  100  acquires the sound representative sound of the identified kind of object from a sound database  190  for storing the representative sound of the object for each kind such as a dog and a bird. Then the image capturing apparatus  100  provides the acquired sound in association with the captured image to the output apparatus  140 . The output apparatus  140  receives an instruction on editing the image by the user  180 . For example, the output apparatus  140  combines a plurality of images designated by the user  180  in the layout designated by the user  180  to generate an output image. At this time, the output apparatus  140  generates an output sound obtained by combining the sounds associated with each of the images used for generating the output image by the ratio of the sound volume same as the dimension ratio of each image in the output image. Then, the output apparatus  140  reproduces the generated output image in synchronism with displaying the output image. Therefore, the output apparatus  140  can provide an output image obtained by combining the image shown on a dog and the image shown on a bird along with the output sound in which the dog&#39;s bark and the birdcall is combined to the user  180 . Thereby the user  180  can easily appreciate a desirable sound depending on the content of the edited output image using the output apparatus  140 . 
       FIG. 2  shows an example of a block configuration of the output apparatus  140  according to the embodiment.  FIG. 2  shows an example of a block configuration of the output apparatus  140  for controlling not to output the same sound again for the same image. The output apparatus  140  includes an image storage section  210 , an image output control section  212 , an image output section  214 , an output instruction reception section  240 , an output allowed time setting section  242 , an output time detection section  244 , a sound storage section  220 , a sound output control section  222 , a sound output section  224 , an output number of times holding section  230 , a target number of times storage section  232 , an output ratio storage section  234  and a limited number of times storage section  236 . 
     The image storage section  210  stores a plurality of captured images. The image storage section  210  stores information indicative of the timings at which the plurality of images are captured in association with each of the plurality of images, respectively. Specifically, the image storage section  210  stores the times at which the plurality of images are captured in association with each of the plurality of images, respectively. 
     The output instruction reception section  240  receives an instruction on outputting the plurality of images stored in the image storage section  210 . The image output control section  212  controls the image output section  214  to output the images stored in the image storage section  210  based on the instruction by the output instruction reception section  240 . The image output section  214  may be a display device for outputting images such as a LCD, or a printing device for printing images. 
     The sound storage section  220  stores a plurality of recorded sounds. For example, the sound storage section  220  stores the plurality of sounds recorded by a recording function of the image capturing apparatus  100  which captured the plurality of images stored in the image storage section  210 . Specifically, the sound storage section  220  stores the sound recorded by the recording function of the image capturing apparatus  100  when the plurality of images stored in the image storage section  210  are captured and also stores the sound recorded by the recording function of the image capturing apparatus  100  when the plurality of images stored in the image storage section  210  are not captured. 
     The sound storage section  220  stores information indicative of the timings at which the plurality of sounds are recorded in association with each of the plurality of sounds, respectively. Specifically, the sound storage section  220  stores the times at which the plurality of sounds are recorded in association with each of the sounds, respectively. Here, the time at which the sound is recorded may be a time at which the recording is started or a time at which the recording is terminated. Additionally, the sound storage section  220  may store information indicative of the times at which the plurality of images are started to record and the order of recording the plurality of sounds. 
     The sound storage section  220  stores a plurality of sound recorded within a recording period equal to or longer than an image capturing period including a plurality of times at which the plurality of images stored in the image storage section  210  is captured. Here, the total time of the plurality of sound stored in the sound storage section  220  is longer than the time obtained by multiplying a preset output time at which the image output section outputs one image by the number of the plurality of images stored in the image storage section. 
     The sound output section  224  outputs the sound stored in the sound storage section  220 . Specifically, the sound output section  224  may be a reproducing device for reproducing sounds. Additionally, the sound output section  224  may include a display device for outputting characters, such as a LCD and output the sound stored in the sound storage section  220  as characters on the display device. Further, the sound output section  224  may include a printing device for printing characters such as a printer. 
     The sound output control section  222  selects a first sound among the plurality of sounds stored in the sound storage section  220  and causes the sound output section  224  to output the same when the image output section  214  output images, alternatively, selects a second sound different from the first sound among the plurality of sounds stored in the sound storage section  220  and causes the sound output section  224  to output the same when the image output section  214  outputs the same image again. Therefore, the user  180  can appreciate different sounds for each outputted image. 
     Here, the sound output control section  222  selects the sound in the order corresponding to the recording timing close to the timing at which the image is captured. For example, the sound output control section  222  selects the sound in the order corresponding to the recording time close to the time at which the image is captured. Additionally, the sound output control section  222  may select the sound in descending order of the volume. Therefore, the user  180  can preferentially appreciate the characteristic sound at the time at which the image was captured. 
     The output number of times holding section  230  counts the output number of times at which the plurality of sounds stored in the sound storage section  220  are outputted by the sound output section  224 . The target number of times storage section  232  stores the target number of times at which the plurality of sounds stored in the sound storage section  220  should be outputted by the sound output section  224 . Then, the sound output control section  222  may select the sound in descending order of the value obtained by subtracting the output number of times from the target number of times. 
     The output ratio storage section  234  stores the output ratio being the ratio of the number of times at which the plurality of sounds stored in the sound storage section  220  should be outputted by the sound output section  224 . Then, the sound output control section  222  may select the sound in order that the ratio of the output number of times held by the output number of times holding section  230  is close to the output ratio stored in the output ratio storage section  234 . Therefore, the user  180  can more appreciate the characteristic sound at the time at which the image was captured. 
     Here, the sound storage section  220  stores the plurality of sounds recorded by the recording function in both of an image capturing modes in which the image capturing apparatus can accept an image capturing operation and an non-image capturing mode in which the image capturing apparatus  100  can not accept any image capturing operation in association with the operation mode when the sound is recorded. Then, the sound control section  222  preferentially selects the sound recorded in the image capturing mode than the sound recorded in the non-image capturing mode. 
     If the sound is limited to be outputted when the sound stored in the sound storage section  220  is outputted from the sound output section  224 , the limited number of times storage section  236  counts the limited number of times and stores the same. Then the sound output control section  222  preferentially selects the sound which is stored in the limited number of times storage section lesser times. Here, sound output control section  222  may calculate the limited ratio for limiting to output the sound based on the output number of times held by the output number of times holding section  230  and the number of times stored in the limited number of times storage section and preferentially select the sound of which calculated limited ratio is smaller. 
     The output time detection section  244  may detect the time at which the output instruction reception section  240  receives the instruction. Then, the output allowed time setting section  242  sets the tolerance of the difference between the times at which the plurality of images stored in the image storage section  210  are captured and the time at which the sound selected from the plurality of sounds stored in the sound storage section  220  is recorded based on the difference between the time detected by the output time detection section  244  and the times at which the plurality of images stored in the image storage section  210  are captured. Then, the sound output control section  222  selects the sound to be outputted by the sound output section  224  among the sounds recorded within the tolerance set by the output allowed time setting section  242 . 
     Specifically, the output allowed time setting section  242  sets the tolerance of the difference between the times at which the plurality of images stored in the image storage section  210  are captured and the time at which the sound selected from the plurality of sound stored in the sound storage section  220  is recorded to be larger when the difference between the time detected by the output time detection section  244  and the times at which the plurality of images stored in the image storage section  210  are captured is larger. Therefore, the output apparatus  140  outputs the image captured at near past along with the sound selected among the sound recorded at the time close to the image capturing time, so that the sound outputted along with the image can be more natural for the user  180 . Additionally, the output apparatus  140  can output the sound selected from the sounds recorded within wider time range when the image captured at the distant past is outputted, so that the user  180  can appreciate more characteristic sound. 
     The above-described output apparatus  140  can select the sound to be outputted among the plurality of sounds even if the same image is outputted again. Therefore, the user can appreciate both of the sound and the image without getting bored. Additionally, the user  180  can appreciate more characteristic sound at capturing the image to be outputted by the output apparatus  140  along with the image. 
       FIG. 3  shows a table indicative of an example of data stored in the sound storage section  220  according to an embodiment of the present invention. The sound storage section  220  stores sound IDs for identifying a plurality of sound data and times at which the sounds are recorded in association with a plurality of sound data. Here, the times at which the sound are recorded may be the time at which a recording is started and the time at which the recording is terminated. Additionally, the time at which the sound is recorded may include the date at which the sound is recorded. 
       FIG. 4  shows an example of the time relationship between a sound-recording and an image-capturing. The image capturing apparatus  100  has operation modes including a standby mode, an image capturing mode and an output mode. Then, the output apparatus  140  stores the sound which are recorded within a period for which the image capturing apparatus  100  is in any of the standby mode, the image capturing mode or the output mode. Here, the image capturing mode may be an operation mode in which the image capturing apparatus  100  can capture an image and/or record a sound. For example, the image capturing mode may be an operation mode in which the image capturing apparatus  100  can capture an image by pushing a release button by the user  180 . The output mode may be an operation mode in which the image capturing apparatus  100  can output an image and/or a sound. For example, the output mode may be an operation mode in which the image capturing apparatus  100  can read the image stored in such a memory and display the same on the display device such a monitor screen. 
     Here, the image capturing apparatus  100  is set the standby mode immediately after activating. The image capturing apparatus  100  is shifted to the image capturing mode when any operation regarding an image-capturing or a recording is executed by the user  180  provided that the operation mode is set the standby mode or the output mode. Where, the operation regarding the image-capturing includes an image capturing and an adjusting of any image-capturing condition such as a shutter speed and a focal length. Additionally, the operation regarding the recording includes a recording of a sound and an adjusting of any recording condition such as a recording sensitivity. The image capturing apparatus  100  is shifted to the output mode when any operation regarding an outputting of the image capturing apparatus  100  is executed by the user  180  provided that the operation mode is set to the standby mode or the image capturing mode. The operation regarding the outputting includes an outputting of an image, a selecting of the image to be outputted and an adjusting of an output condition such as an output speed. Here, the image capturing apparatus  100  may be shifted to the standby mode when the image capturing apparatus  100  is set to the image capturing mode or the output mode provided that any operation is not executed by the user  180  for a predetermined period. Thus, the image capturing apparatus  100  is shifted to the image capturing mode without capturing any image when the release button is pushed by the user  180  provided that the operation mode is set to the standby mode or the output mode except for the image capturing mode. Additionally, the standby mode and the output mode may be an operation mode in which the image capturing apparatus  100  does not allow the release button to be pushed by the user  180 . 
     The sound storage section  220  stores sounds # 404  and # 406  which are recorded by the image capturing apparatus  100  during a period for which the image capturing apparatus  100  is set to the image capturing mode (t 422 -t 428 ). Additionally, the sound storage section  220  stores sounds # 408  and # 410  which are recorded by the image capturing apparatus  100  during a period for which the image capturing apparatus  100  is set to the output mode (t 428 -t 430 ). Further, the sound storage section  220  also stores sounds # 402 , # 403  and # 412  which are recorded by the image capturing apparatus  100  during a period for which the image capturing apparatus  100  is set to the standby mode (t 420 -t 422  and t 430 -t 432 ). 
     Additionally, the sound storage section  220  stores a sound having the length obtained by multiplying a predetermined output time (Δt 452 ) at which the image output section  214  outputs one image by the number of images stored in the image storage section  210 . For example, the sound storage section  220  stores two or more sounds (# 404 , # 406 , # 408 , # 410  and # 412 ) having the length for the output time Δt 452 , and the sounds # 402  and # 403  having the length for the output time Δt 451  which is half as long as Δt 452  as the output sound for two images captured at a time t 424  and a time t 426  when the output time per image is Δt 452 . Therefore, the sound output control section  222  can select a different sound among the plurality of sounds and output the same for each time at which the image output section  214  outputs the image. 
     Additionally, the sound output control section  222  may select the plurality of images and cause the sound output section  224  to output the same in order that the total time of the selected sounds is to be a preset time at which the image output section  214  outputs one image when the sound output control section  222  selects the sound to be outputted by the sound output section  224 . For example, the sound output control section  222  may select the sounds # 402  and # 403  having the length being half as long as the output time Δt 452  and cause the sound output section  224  to output the same when the image captured at the time t 424  is outputted. Additionally, the sound output control section  222  may select the sound # 408  or # 410  having the divided length Δt 452 , respectively and cause the sound output section  224  to output the same when the sound storage section  220  stores the sound having the length longer than the output time Δt 452 . 
     The image output control section  212  may adjust the output time at which the image output section  214  outputs an image based on the number of images outputted from the image output section  214  and the total time for the plurality of sounds to be outputted. For example, the image output control section  212  causes the image output section  214  to output each image for periods obtained by the total time of the plurality of sounds to be outputted by the number of images to be outputted when the output instruction reception section  240  receives the plurality of sounds and images to be outputted from the user  180 . 
     Here, when the sound output control section  222  receives the instruction on outputting images captured at the time t 424  from the output instruction reception section  240 , the sound output control section  222  outputs the sounds in the order corresponding to close to the time at which each image is captured for each time at which the image is outputted. For example, when the sound output control section  222  outputs the image captured at the time t 424 , the sound output control section  222  sequentially selects the sounds in the order of # 404 , # 406 , # 402 , # 403 , # 408 , # 410  and “ 412  and causes the sound output section  224  to output the same. Additionally, the sound output control section  222  sequentially selects the sound in descending order of the volume such as # 406 , # 404 , # 408 , # 410 , # 403  # 402  and # 412  and causes the sound output section  224  to output the same. Here, the sound output control section  222  may select the sound having the volume larger than a predetermined threshold sound volume. At this time, the sound output control section  222  may set the threshold sound volume in order that the total length of the selected sounds is longer than a predetermined output time. 
     The image capturing apparatus  100  may record the sound having the preset volume among sounds surrounding the image capturing apparatus  100 . For example, the image capturing apparatus  100  may record the sound having the volume larger than the preset threshold sound volume. Additionally, the image capturing apparatus  100  may record the sound having the volume larger than the preset volume changed by changing the recording sensitivity. Then, the image capturing apparatus  100  may store the sound recorded in association with the preset sound volume. Then, the image storage section  210  acquires the sound recorded by the image capturing apparatus  100  in association with the preset sound volume and stores the same. Then, the sound output control section  222  calculates the ratio of the sound volume to the preset sound volume associated with the sound and may select the sound in descending order of the ratio. Thereby the sound output control section  222  can select the sound in descending order of the ratio of the sound volume to the preset sound volume. Additionally, the sound output control section  222  may select the sound in descending order of the ratio of the sound volume to the preset sound volume being the difference between the recorded sound volume and the preset sound volume at the recording time. Therefore, the sound recorded with a low threshold sound volume is easily reproduced by the output apparatus  140  even if the magnitude of the sound volume is small. For example, in the case that the user  180  records the sound of small insects with the low threshold sound volume while the user  180  captures the image of the insects, the sound of small insects is easily reproduced by the output apparatus  140 . Thus, the output apparatus  140  can preferentially reproduce the sound reflecting the user  180 &#39;s intention at image-capturing. 
       FIG. 5  shows a table indicative of another example of data stored in a sound storage section  220 . The sound storage section  220  stores sound IDs for identifying sound data, times at which sounds are recorded and indexes in association with sound data. Here, the times stored in the sound storage section  220  may be a time at which a recording is started. The indexes stored in the sound storage section  220  may be a value indicative of the timing at which a sound is recorded. For example, the sound storage section  220  stores the value indicative of the order that each sound is recorded from the time at which the recording is started as indexes. The sound output control section  222  determines the timing at which the sound is recorded from the time and the index stored in the sound storage section  220 . The sound output control section  222  may sequentially select the sound in the order corresponding to the timing at which the sound is recorded is close to the timing at which the image to be outputted by the image output section  214  is captured. 
     The sound storage section  220  may store sound data in association with the sound volume of the sound data. Here, the sound volume may be the average sound volume being an average of sound volume per hour of the sound data, and may be the maximum sound volume or the minimum sound volume of the sound data. Additionally, the sound volume may be the intermediate sound volume being the average of the maximum sound volume and the minimum sound volume. Therefore, the sound output control section  222  can rapidly select the sound when the sound is sequentially selected in descending order of the volume. 
     Additionally, the sound storage section  220  may store sound data in association with the time change of the sound volume. The time change of the sound volume may be the time change in itself or information indicative of the change of the magnitude of the sound volume (for example, an increasing speed and a decreasing speed). Then, the sound output control section  222  may select the sound from the sound storage section according to the size or the change of size of the image displayed on the image output section  214  and cause the sound output section  224  to output the same. For example, the sound output control section  222  may select the sound having the volume which is increasing from the sound storage section  220  and cause the sound output section  224  to output the same when the image output section  214  displays an image as enlarging the same. Alternatively, the sound output control section  222  may select the sound having the volume which is decreasing from the sound storage section  220  and cause the sound output section  224  to output the same when the image output section displays an image as reducing the same. 
     provided that the operation mode is set the standby mode of the output mode. 
     Additionally, the sound storage section  220  may store the data of the sound stereophonically recorded in association with the time change of each of the right sound and the left sound. Here, the time change of the right sound and the left sound may be the time change of the right sound and the left sound themselves, or information indicative of the change of the magnitude of the sound volume (an increasing speed or a decreasing speed). Then, the sound output control section  222  may select the sound from the sound storage section  220  and cause the sound output section  224  to output the same according to the position of the image or the change of the position displayed on the image output section  214 . For example, the sound output control section  222  may select the sound of which right side volume is large and left side volume is small and output the same when the image output section  214  displays the image as sliding the same from right to left. Therefore, the output apparatus  140  can reproduce a desirable image according to the position and the size of the image to be displayed. 
       FIG. 6  shows a table indicative of an example of data stored in a target number of times storage section  232 . The target number of times storage section  232  stores the target number of times being the number of times at which the sounds identified by the sound IDs should be outputted by the sound output section  224  in association with the sound IDs stored in the sound storage section  220 . Here, the output number of times holding section  230  stores the output number of times at which the sounds are outputted by the sound output section  224  in association with the sound IDs stored in the sound storage section  220 . Then, the sound output control section  222  calculates the value obtained by subtracting the output number of times held by the output number of times holding section  230  from the target number of times and selects the sound in descending order of the value to cause the sound output section  224  to output the same. Therefore, the target number of times of more characteristic sound when the image is captured by the image capturing apparatus  100  is set more times, so that the characteristic sound at the image-capturing can be outputted more times when the image is outputted. Additionally, since sounds other than the characteristic sound are outputted sometimes after outputting the characteristic sound at image-capturing many times, the user can appreciate the image without getting bored. 
     The target number of times storage section  232  may store a target number of times set by the user  180 . Additionally, the target number of times storage section  232  may set a target number of times based on the volume of the sound stored in the sound storage section  220 . For example, the target number of times storage section  232  may set the target number of times of the sound having larger volume more times. Additionally, the target number of times storage section  232  may set the number of times at which the sound including a human voice should be outputted more times than that at which the sound not including any human voice should be outputted. 
     Additionally, the target number of times storage section  232  may store the target number of times at which the plurality of images should be outputted for each image stored in the image storage section  210 . Specifically, the target number of times storage section  232  stores image IDs stored in the image storage section  210 , sound IDs and target number of times. Then, the sound output control section  222  selects the sound in descending order of the value obtained by subtracting the output number of times from the target number of times among the plurality of sounds stored in association with the image ID for identifying the image and causes the sound output section  224  to output the same when the image output section  214  output the image. 
       FIG. 7  shows a table indicative of an example of data stored in an output ratio storage section  234 . The output ratio storage section  234  stores the output ratio being a ratio of the number of times at which the sound identified by the sound ID should be outputted by the sound output section  224  in association with the sound IDs stored in the sound storage section  220 . Then, the sound output control section  222  calculates the ratio of the number of times at which each sound is outputted based on the output number of times held by the output number of times holding section  230  and selects the sound in order that the ratio of the output number of times is close to the output ratio stored in the output ratio storage section  234 . Thereby when the output ratio of the characteristic sound when the image is captured by the image capturing apparatus  100  is larger, the characteristic sound at the image-capturing can be outputted more times. Therefore, the user  180  can appreciate the characteristic sound at image-capturing many times along with various sounds while the user  180  views the image. 
     The output ratio storage section  234  may store an output ratio set by the user  180 . Additionally, the output ratio storage section  234  may set an output ratio based on the volume of the sound stored in the sound storage section  220 . For example, the output ratio storage section  234  may set the output ratio at which the sound having larger volume is outputted to be larger. Further, the output ratio storage section  234  may set the output ratio at which the sound including a human vice should be outputted to be more than that at which the sound not including a human voice should be outputted among the sounds stored in the sound storage section  220 . 
     Additionally, the image storage section  210  may store the output ratio being a ratio of the number of times at which a plurality of sounds should be outputted for each image stored in the image storage section  210 . Specifically, the output ratio storage section  234  stores image IDs stored in the image storage section  210 , sound IDs, and output ratios. Then, the sound output control section  222  may select the sound among the plurality of sounds stored in association with each image ID for identifying the image to be outputted in order that the ratio of the output number of times is close to the output number of times stored in the output ratio storage section  234  and cause the sound output section  224  to output the same when the image is outputted from the image output section  214 . 
     The limited number of times storage section  236  stores in association with the image IDs the limited number of times at which the sound is limited to be outputted when the sound stored in the sound storage section  220  is outputted from the sound output section  224 . For example, the limited number of times storage section  236  increases the limited number of times stored in association with its sound ID by one for each time at which the sound is canceled to reproduce by fast-forwarding the sound by the user  180 . Additionally, the limited number of times storage section  236  may increase the limited number of times stored in association with its sound ID for each time at which the volume of the sound reproduced by the sound output section  224  is reduced by turning the volume down by the user  180 . Further, the limited number of times storage section  236  may increase the limited number of times stored therein depending on the amount of reducing of the sound reproduced by the sound output section  224 . For example, the limited number of times storage section  236  may increase the stored limited number of times by one provided that the amount of reducing of the volume of the sound reproduced by the sound output section  224  is larger than a predetermined reference amount of reducing. Then, the limited number of times storage section  236  may increase the stored limited number of times by a predetermined increasing number of times (such as 1&lt;0) depending on the amount of reducing of the sound volume when the amount of reducing of the sound volume is less than the predetermined reference amount of reducing. 
     Then, the target number of times storage section  232  sets the target number of times store in association with the sound IDs of the sounds stored in the limited number of times storage section  236  fewer times to be more times. The output ratio storage section  234  sets the output ratio stored in association with the sound IDs of the sounds stored in the limited number of times storage section fewer times to be more times. Therefore, the sound output control section  222  can frequently output the sound stored in the limited number of times storage section  236  fewer times by the sound output section  224 . Here, the target number of times storage section  232  or the output ratio storage section  234  may calculate a certain limited ratio obtained by dividing the number of times stored in the limited number of times storage section  236  by the output number of times held by the output number of times holding section  230  to set the target number of times or the output ratio stored in association with the sound ID of the sound of which calculated limited ratio is smaller to be larger. 
     The target number of times storage section  232  may set the target number of times of the sound stored in the sound storage section  220  in association with the image capturing mode to be larger and store the same. The output ratio storage section  234  may set the output ratio of the sound stored in the sound storage section  220  in association with the image capturing mode to be larger and store the same. Therefore, the sound output control section  222  can output the sound recorded while the image capturing apparatus  100  is set to the image capturing mode by the sound output section  224  more frequently than the sound recorded while the image capturing apparatus  100  is set to the standby mode and the output mode. Here, the target number of times storage section  232  and the output ratio storage section  234  may store the target number of times and the output ratio weighted by an weighting factor indicated by the inverse number of the limited number of times, respectively. Additionally, the target number of times storage section  232  and the output ratio storage section  234  may calculate the target number of times and the output ratio of the sound stored in association with the image capturing mode by weighting the sound by the factor larger than the sound stored in association with the standby mode or the output mode. 
       FIG. 8  shows an example of a time range for which a sound output control section  222  selects the sound. For example, on receiving an instruction on outputting the image captured at a time t 804  from the user  180  at a time  806 , the output allowed time setting section  242  determines an allowed time Δt 852  for selecting the sound to be outputted by the sound output section  224  based on the difference between the instructed output time and the time at which the image to be outputted was captured (t 806 −t 804 ). Then, the sound output control section  222  selects the sound among the sounds (# 841 -# 849 ) recorded within the time range before/after the time t 804  by the Δt 852  (the time t 804 −theΔ 852 ˜t 804 +theΔ 852 ) and causes the sound output section  224  to output the same. 
     The sound output control section  222  may select the sound recorded from the time before the time t 804  by the tolerance Δt 852  to the time  804 . Alternatively, the sound output control section  222  may select the sound recorded from the time  804  to the time after the time t 804  by the tolerance Δt 852 . 
     The output allowed time setting section  242  sets the tolerance within which the sound to be outputted from the sound output section  224  is selected to be larger in proportion to the magnitude of the difference between the time at which the captured image stored in the image capturing section  210  was captured and the time at which the instruction on outputting was received. In  FIG. 8 , on receiving at the time t 806  the instruction on outputting the image captured at the time t 802  before the time t 804 , the output allowed time setting section  242  sets a tolerance Δt 850  longer than the tolerance Δt 852 . Then, the sound output control section  222  selects the sound among the sounds (# 811 -# 834 ) recorded within the time range from the time (t 802 −Δt 850 ) to the time (t 802 +Δt 850 ) and causes the sound output section  224  to output the same. 
     The output allowed time setting section  242  may set a period obtained by dividing the period between the time at which the image was captured and the instructed output time by a predetermined number as the tolerance. For example, the sound output control section  222  selects the sound among the sounds recorded in one day before/after the time at which the image was captured when the image captured ten days ago is outputted. Additionally, the sound output control section  222  selects the sound among the sounds recorded in four years before/after the time at which the image was captured when the image of the athletic festival at the third-grade level of the elementary school is outputted forty years later. In this case, the especial characteristic sounds at the entrance ceremony and the graduation ceremony of the elementary school are outputted while the user  180  appreciates the scene of the athletic festival, so that the user  180  can more enjoyably appreciate the image. 
     As thus described above, the output apparatus  140  selects the sound to be outputted among a plurality of sounds even if the same image is outputted again, so that the user  180  can easily appreciate the sound and image without getting bored. 
       FIG. 9  shows an example of a block configuration of an image capturing apparatus  100 .  FIG. 10  shows the block configuration in another embodiment of the output apparatus  140 . The output apparatus  140  and the image capturing apparatus  100  according to the present embodiment generates an appropriate output sound for an output image generated using a plurality of trimming images obtained by trimming plurality of images or an image and synchronously outputs the sound and the image. The image capturing apparatus  100  includes an image capturing section  910 , a recording section  920 , an object extraction section  930 , an object position identification section  940  and a sound acquiring section  950 . 
     The image capturing section  910  captures images. The object extraction section  930  extracts the object included in the image captured by the image capturing section  910 . The object position identification section  940  identifies the object position associated with the sound acquired by the sound acquiring section  950  in the image captured by the image capturing section  910 . 
     The sound acquiring section  950  acquires a sound associated with the object extracted by the object extraction section  930 . Specifically, the sound acquiring section  950  acquires the sound associated with the kind of the object extracted by the object extraction section  930  from the sound database for storing the sounds in association with the kind of object. Then, the sound storage section  960  stores the sound acquired by the sound acquiring section  950  in associated with the position of the object identified by the object position identification section  940 . 
     The recording section  920  records sounds surrounding the image capturing section  910 . Here, the microphone  102  described with reference to  FIG. 1  may be a part of the recording section  920 . The sound acquiring section  950  may extract the sound associated with the object extracted by the object extraction section  930  from the sounds recorded by the recording section  920 . In this case, the object position identification section  940  identifies the position of the object associated with the sound extracted by the sound acquiring section  950  in the image captured by the image capturing section  910 . Then, the sound storage section  960  stores the sound extracted by the sound acquiring section  950  in association with the object position identified by the object position identification section  940 . 
     The output apparatus  140  includes an image storage section  1010 , an object extraction section  1030 , an object position identification section  1040 , a sound acquiring section  1050 , a sound storage section  1060 , a partial region acquiring section  1020 , an output sound generating section  1075 , an image output section  1080  and a sound database  1090 . 
     The image storage section  1010  stores images. Specifically, the image storage section  1010  receives the image captured by the image capturing apparatus  100  therefrom and stores the same. The sound storage section  1060  stores the sound in association with the image stored in the image storage section  1010  and the position of the image. Specifically, the sound storage section  1060  acquires the sound recorded in association with the image captured by the image capturing apparatus  100  and the position in the image from the sound storage section  1060  of the image capturing apparatus  100 . 
     The partial region acquiring section  1020  acquires a partial region including at least a part of the image stored in the image storage section  1010 . For example, the partial region acquiring section  1020  accepts a trimming operation on the image stored in the image storage section  1010  by the user  180  and acquires a trimming range indicated by the trimming operation as the range of the partial region. 
     The output image generating section  1075  generates an output image from the image within the partial region acquired by the partial region acquiring section  1020  in the image stored in the image storage section  1010 . The output sound generating section  1070  generates an output sound from the sound stored in the sound storage section  1060  in association with the position in the total image at which the partial region acquired by the partial region acquiring section is located in the image stored in the image storage section  1010 . 
     Then, the image output section  1080  outputs an output image generated by the output image generating section  1075  and an output sound generated by the output sound generating section  1070  in association with each other in order to synchronously output them. Here, the image output section  1080  may record the output image and the output sound in association with each other on a recording media. Additionally, the image output section  1080  may output the output image and the output sound in association with each other in order to output the output sound from a reproducing device such as a speaker in synchronism with displaying the output image on a display device. Therefore, the output apparatus  140  can reproduce the appropriate sound such as the representative sound of the object included in the trimming image in synchronism with the trimming image when the trimming image acquired by the trimming operation by the user  180  is displayed. 
     The output image generating section  1075  may combine the image within the partial region acquired by the partial region acquiring section  1020  in the image stored in the image storage section  1010  with the other images stored in the image storage section  1010  to generate an output image. In this case, the sound generating section  1070  generates an output sound by the sound stored in the sound storage section  1060  in association with the position in the total image at which the partial region acquired by the partial region acquiring section  1020  is located and the sound stored in the sound storage section  1060  in association with the other images included in the output image. Therefore, the output apparatus  140  can reproduce the sound which can be acquired by combining the sounds associated with the image used for editing in synchronism with displaying the edited image when the image obtained by editing a plurality of images is displayed. 
     The sound database  1090  stores the sounds in association with the kind of objects. Then, the sound storage section  1060  acquires the sound stored in the sound database  1090  in association with the kind of the object located at the position associated with the image stored in the image storage section  1010  and stores the same. Here, the sound storage section  1060  may acquire the sound stored in a sound database outside of the output apparatus  140  in association with the kind of the object located at the position in association with the image stored in the image storage section  1010 . 
     Then, the output sound generating section  1070  may generate an output sound obtained by enhancing the sound stored in the sound storage section  1060  in association with the position in the total image at which an object occupying larger dimension in the output image is located and the image including the object. Specifically, the output sound generating section  1070  may generate an output image obtained by combining the sound stored in the sound storage section  1060  in association with the position in the total image at which an object occupying larger dimension in the output image is located and the image including the object with larger volume. 
     Additionally, the output sound generating section  1070  may generate an output image obtained by enhancing the sound stored in the sound storage section  1060  in association with the position in the total image at which an object disposed at more front in the output image is located and the image including the object. Specifically, the output sound generating section  1070  generates an output sound obtained by combining the sound stored in the sound storage section  1060  in association with the position in the total image at which an object disposed at more front in the output image is located and the image including the object with larger volume. 
     The output image generating section  1075  may generate output sounds by sequentially outputting the plurality of sounds stored in the sound storage section  1060  in association with each of the plurality of images used for generating the output image. In this case, the output sound generating section  1070  may generate output sound by outputting for longer times the sound stored in the sound storage section  1060  in association with the position in the total image at which an object occupying larger dimension in the output image is located and the image including the object. Additionally, the output sound generating section  1070  may generate output sound by outputting for longer times the sound stored in the sound storage section  1060  in association with the position in the total image at which an object disposed at more front in the output image is located. 
     As described above, the output apparatus  140  can reproduce the image generated using the trimming image acquired by freely trimming images by the user  180  along with the sound of the object shown on the image. Therefore, it can be prevented before that an undesirable sound is reproduced, for example, the sound associated with the object eliminated by trimming is reproduced along with the output image. Additionally, the output apparatus  140  can provide the sound obtained by enhancing the sound associated with more enhanced object in a composite image along with the composite image to the user  180 . 
     The sound storage section  1060  may store a plurality of sounds in association with each of the plurality of images stored in the image storage section  1010 . Then, the output image generating section  1075  may combine the plurality of images stored in the image storage section  1010  to generate an output image. For example, the output image generating section  1075  generates an output image by positioning the plurality of images selected by the user  180  in the layout designated by the user  180 . In this case, the output sound generating section  1070  generates an output sound using a first sound and a second sound stored in the sound storage section  1060  in association with each of a first image and a second image included in the output image generated by the output image generating section  1075 . Here, the output sound generating section  1070  generates an output sound obtained by enhancing the first sound than the second sound and combining them when the first image is enhanced than the second image in the output image generated by the output image generating section  1075 . Therefore, the output apparatus  140  can output the output sound obtained by enhancing the sound associated with the image emphatically positioned in the output image by the user  180  in synchronism with the output image. 
     Specifically, the output sound generating section  1070  generates an output sound obtained by enhancing the first sound than the second and combining them when the fist image is larger than the second image in the output image generated by the output image generating section  1075 . Additionally, the output sound generating section  1070  generates an output sound obtained by enhancing the first sound than the second sound and combining them when the first image is in front of the second image in the output image generated by the output image generating section  1075 . Further, the output sound generating section  1070  generates an output sound obtained by enhancing the first sound than the second sound and combining them when the first image is located more center than the second image in the output image generated by the image generating section  1075 . Here, the output sound generating section  1070  may generate an output sound obtained by combining the first sound and the second sound having the volume smaller than that of the first sound when the first image is enhanced than the second image in the output image generated by the image generating section  1075 . 
       FIG. 11  shows an example of data stored in a sound database  1090 . The sound database  1090  stores the kind of objects and sound data. For example, the sound database  1090  stores the representative sound for each object, such as a bark of dog, a bird call and sound of the waves in association with each kind of objects, such as a dog, a bird and waves. Here, the sound database  190  may store data same as the data stored in the sound database  1090  as shown in  FIG. 11 . 
       FIG. 12  shows an example of an image  1200  stored in an image storage section  1010 . Now, an operation when the sound acquiring section  1050  acquires sounds will be described with reference to the image  1200  in  FIG. 12 . The object extraction section  1030  extracts the outline of objects such as a dog  1210  and a bird  1220  from the image  1200  using an edge extraction. Then, the object extraction section  1030  identifies the kind of object having the coincidence higher than a predetermined value and having the maximum coincidence by pattern-matching the pattern of the object previously stored for each kind of objects such as a dog and a bird with the extracted outline. Then, the sound acquiring section  1050  acquires the sound stored in the sound database  1090  or the sound database  190  in association with the identified kind of object. 
     The sound acquiring section  950  of the image capturing apparatus  100  can acquire the sound from the sound database  190  in association with the object of the image captured by the image capturing section  910  through the operation same as that of the sound acquiring section  1050 . Additionally, the sound acquiring section  950  previously stores the amount of characteristic of sound in association with the kind of object. Then, the sound acquiring section  950  may compare the stored amount of characteristic of the sound with the amount of characteristic of the sound recorded by the recording section  920  and extract the sound having the amount of characteristic being higher than the predetermined coincidence and having the maximum coincidence from the sound recorded by the recording section  920 . Here, the amount of characteristic of the sound may be a characteristic frequency spectrum of the sound and a characteristic time change pattern of the frequency spectrum. 
       FIG. 13  shows an example of data stored in a sound storage section  960  or a sound storage section  1060 . Now, the data stored in the sound storage section  1060  will be described as an example. The sound storage section  1060  stores image IDs for identifying images captured by the image capturing section  910 , positions in the total image at which the object included in the image is located and sound data acquired by the sound acquiring section  1050 . Here, the object position identification section  1040  identifies the barycentric position of the object extracted by the object extraction section  1030 . Then, the sound storage section  1060  stores the barycentric position of the object identified by the object position identification section  1040  as the position in the total image of the object. Here, the sound storage section  1060  may store the relative value to the height and the width of the image indicative of the position in the total image. Specifically, the sound storage section  1060  stores the relative coordinate to the height and the width based on the lower left of the image. 
     The sound storage section  1060  may store the sound in association with the image without associating with the position in the total image. As shown in  FIG. 13 , the sound storage section  1060  stores sound data  13  in association with an image ID #AAA, and also stores sound data  22  in association with an image ID #BBB. In this case, the sound storage section  1060  stores a value indicating that it is not associated with the position in the total image (such as null) as the position in the total image for the sound data  13  and  22 . Hereinbefore, the data stored in the sound storage section  1060  has been described, then, the sound storage section  960  may store data same as the data stored in the sound storage section  1060 . 
       FIG. 14  shows an example of the output image generated by an output image generating section  1075 . As shown in  FIG. 14 , the output apparatus  140  generates an output image  1450  by the image identified by the image ID #AAA and the image  1400  identified by the image ID #BBB and displays the same. The output generating section  1075  positions a partial image  1411  and a partial image  1412  within the range acquired by the partial region acquiring section  1020  according to a trimming instruction by the user  180  in a layout designated by the user  180  to generate the output image  1450 . 
     At this time, the output sound generating section  1070  calculates the dimension of the image  1200  and the image  1400  included in the output image  1450 . Then, the output sound generating section  1070  combines the sound  13  and the sound  22  stored in the sound storage section  1060  in association with the image  1200  and  1400  with the volume in proportion to the dimension of the image  1200  and  1400  in the output image  1450  to generate an output sound. Thereby, the sound including children&#39;s voice (sound data  22 ) recorded when the image  1400  (#BBB) occupying a large dimension in the output image  1450  is reproduced with a large volume. Therefore, the sound recorded when the image having a small dimension (#AAA) included in the output image  1450  was captured is not reproduced with a large volume, so that the user can appreciate the output image without any uncomfortable feeling. 
     Additionally, the output sound generating section  1070  may generate an output sound depending on the dimension of the object in the output image  1450 . Specifically, the output sound generating section  1070  calculates the dimension of the object in the output image (such as a dog object  1421  and a sea object  1422 ) included in the range acquired by the partial region acquiring section  1020 . Then, the output sound generating section  1070  acquires the sound data  11  and  21  stored in the sound storage section  1060  in association with each position in the total image of the objects  1421  and  1422 , the image IDs of the images  1200  and  1400  and combines the acquired sound data  11  and  12  with the volume in proportion to the dimension of the object to generate an output sound. Here, the output sound generating section  1070  may generate identification information for identifying sound data used for the output sound and sound volume information indicative of the volume of the sound data as an output sound instead of the sound data in itself. As described above, when the output image  1450  is displayed by the output apparatus  140 , sound of the waves is reproduced with the volume larger than that of the bark of a dog. Thus, the output apparatus  140  allows the user  180  to appreciate the image generated by freely editing by the user  180  along with the sound without any uncomfortable feeling about the content of the image. 
     Here, the case that the output sound generating section  1070  combines the sound with the volume depending on the dimension of the image or the object in the output image  1450  has been described with reference to  FIG. 14 . Additionally, the output sound generating section  1070  may determine the combination ratio of the sound depending on the layout of the image or the object in the output image  145  in addition to the dimension. For example, the output sound generating section  1070  may combine sounds with the combination ratio weighted by the weighting factor in proportion to the inverse number of the distance to the center of the output image  1450 . Additionally, the output sound generating section  1070  may set the weighting factor of the sound corresponding to the image or the object disposed in more front in the output image  1450  to be larger. Here, the composition ratio of the sound may be a composition ratio of the sound volume as described with reference to  FIG. 14 , or may be a composition ratio to the time for which the sound is reproduced. Additionally, the output sound generating section  1070  may generate the sound corresponding to the image or the object having the maximum dimension in the output image  1450  as an output sound. Further, the output sound generating section  1070  may generate the sound corresponding to the image or the object in the image disposed in the most front among the images and objects in the output image  1450  as an output sound. 
       FIG. 15  shows an example of a sound provision system according to a second embodiment of the present invention. The sound provision system includes an image capturing apparatus  100 , an output apparatus  140 , an explanation sound database  170 , a music database  172  and an environmental sound database  174 . In the present embodiment, the image capturing apparatus  100  captures souvenir pictures in the sightseeing spot. The image capturing apparatus  100  transmits the image captured by the image capturing apparatus  100  and the image-capturing position thereof to the output apparatus  140  through the communication line  150  such as Internet. The music database  172  stores plural pieces of music therein. The environmental sound data base  174  individually stores a plurality of environmental sounds for each kind of environmental sounds. Here, the music database  172  and the environmental sound database  174  according to the present embodiment are examples of the sound database of the present invention. 
     The output apparatus  140  acquires the sound data regarding the image capturing position received from the image capturing apparatus  100 , such as sound data for explaining the feature of the sightseeing spot from the explanation sound database  170  and outputs the same along with the image received from the image capturing apparatus  100 . Here, the image capturing apparatus  100  may record the sounds surrounding the image capturing apparatus  100 . The output apparatus  140  may receive the sounds recorded by the image capturing apparatus  100 . Then, the output apparatus  140  may extract the music among the sounds, acquire the music same as the extracted music from the music database  172  and output the same along with the image. Additionally, the output apparatus  140  may extract the environmental sound, such as sound of waves and a bird call among the sounds from the environmental sound database  174 , acquire the environmental sound of which kind is same as that of the extracted environmental sound from the environmental sound database  174  and output the same along with the image. Here, the output apparatus  140  may synchronously output the sound data acquired from the explanation sound database  170  and the music acquired from the music database  172  or the environmental sound acquired from the environmental sound database  174 . 
     The output apparatus  140  may be an apparatus for outputting images and sounds such as a HDTV, an electronic photostand and computer. Additionally, the output apparatus  140  may output sounds as characters. For example, the output apparatus  140  displays lyrics included in the sounds acquired from the explanation sound database  170  and/or music data acquired from the music database  172  as the characters on the display device such as a LCD while the image is displayed on the display device. Here, the output apparatus  140  may display the characters on the display device for displaying images or the other display. Additionally, the output apparatus  140  may be a printing device for printing images, such as a printer and also may print sounds as characters during printing images. 
     The image capturing apparatus  100  may be such as a digital still camera and a camera cell-phone. The image capturing apparatus  100  may record image and sound data on a recording medium and the output apparatus  140  may receive the image and sound data from the recording medium. Further, the image capturing apparatus  100  may store the directories associated with the directories provided for each user  180  in a server connected to the communication line  150 , such as the directories associated with the image capturing apparatus  100 . Then, the output apparatus  140  may receive the image and sound data stored in the server for each user  180 . 
     As thus described above, the output apparatus  140  can provide the image captured by the image capturing apparatus  100  along with the sound associated with the location at which the image is captured to the user  180 . Therefore, the user  180  can enjoyably appreciate the images as reminding the feature of the sightseeing spot. Additionally, the output apparatus  140  can provide the environmental sound, such as the background music and the surrounding sound of the waves when the image was captured by the image capturing apparatus  100  to the user  180 .

The number of image-captured sheets calculation section  286  calculates the number of sheets for which each of the plurality of images stored in the image storage section  210  is captured. 
     The sound acquiring section  262  acquires the sound stored in the explanation sound database  170  according to the dimension of the image capturing region determined by the image capturing region determination section  282 . Specifically, the sound acquiring section  262  acquires the sound with more detailed explanation regarding the image capturing region determined by the image capturing determination section  282  when the dimension of the image capturing region determined by the image capturing region determination section  282  is smaller. 
     More specifically, the sound acquiring section  262  acquires the sound with the explanation regarding the partial region in which distribution density calculated by the image capturing position distribution calculation section  286  is higher than a predetermined density. Additionally, the sound acquiring section  262  acquires the sound with more detailed explanation among the plurality of explanations with different degree of the detail each other regarding the partial region stored in the explanation sound database  170 . 
     The output section  224  outputs the sounds acquired by the sound acquiring section  262  along with the plurality of images stored in the image storage section  210 . Specifically, the output section  224  outputs the sound acquired by the sound acquiring section  262  along with the plurality of images selected by the image selection section  278 . 
     The image storage section  210  further stores the time at which the image is captured in association with the captured image.

The range may include the longitude and latitude being the staring point and the end point of the region. Here, the range may include a plurality of ranges at which the regions are located. The sound data may include a plurality of data with different detail each other regarding each of the regions, such as sound data of a brief description and a detailed description. Additionally, the sound data may include news regarding each of the regions. 
     For example, the brief description data about Japan may be sound data for describing the feature, population and area of the whole of Japan. The detailed description data about Japan may be sound data for describing the feature, population and area for each region in Japan, and also may be sound data for describing Japanese history. 
       FIG. 18  shows an example of the distribution of the positions at which images are captured. As shown in  FIG. 18 , the image storage section  210  stores ten sheets, nine sheets, seven sheets, eight sheets and six sheets of images which are captured in Nagasaki, Hiroshima, Kyoto, Shizuoka, Tokyo and Hokkaido, respectively. The image capturing region determination section  282  divides the image into partial regions for each range by a predetermined longitude and latitude to determine a partial region including the position at which the image is captured. The number of image-captured sheets calculation section  288  calculates the number of sheets of the images captured at each of the partial regions. Then, the image capturing position distribution calculation section  286  determines the distribution of the partial regions including the positions at which the images are captured. 
     Then, the sound acquiring section  262  determines whether the image capturing positions are distributed to a wide range. For example, the sound acquiring section  262  determines that the image capturing position is distributed among the small range when the image captured at Nagasaki is selected by the image selection section  278 , and then, the sound acquiring section  262  acquires sound data for describing about Nagasaki as the sound data of the detailed description about Japan from the explanation sound database  170 . Additionally, when the images captured in Nagasaki, Hiroshima, Kyoto, Shizuoka, Tokyo and Hokkaido, respectively are selected by the image selection section  278 , the sound acquiring section  262  determines that the image capturing positions are distributed to wider range and acquires the sound data for describing about Japan as the sound data of the brief description about the image capturing regions from the explanation sound database  170 . 
     Here, when the number of sheets calculated by the number of image-captured sheets calculation section  288  is larger, the sound acquiring section  262  may acquire the sound data of more detailed description about each of the image capturing regions from the explanation sound database  170 . Alternatively, when the number of sheets calculated by the number of image-captured sheets calculation section  288  is smaller, sound acquiring section  262  may acquire the sound data of the more brief description about each of the image capturing regions from the explanation sound database  170 . 
     Additionally, the sound acquiring section  262  calculates the ratio of the number of sheets of the images captured at a specified partial region to the selected number of sheets, and then, when the ratio is larger than a predetermined ratio, the sound acquiring section  262  acquires the sound data for describing about the specified partial region from the explanation sound database  170 . For example, when the image storage section  210  stores six sheets, seven sheets, thirty sheets, four sheets and three sheets of images coming to a grand total of fifty sheets of images which are captured in Nagasaki, Hiroshima, Kyoto, Tokyo and Hokkaido, respectively, where, thirty sheets more than half of them are the images captured in Kyoto, the sound acquiring section  262  acquires sound data for describing about Kyoto from the explanation sound database  170 . Therefore, the output apparatus  140  can provide the sound for describing about the location at which the images are captured by the user particularly many times. 
       FIG. 19  shows an example of the distribution of the times at which images are captured. The image capturing period determination section  284  determines the time range at which the image is captured for each partial region. For example, the image capturing period determination section  284  determines time ranges (t 1 -t 10 , t 11 -t 19 , t 20 -t 29 , t 30 -t 36 , t 37 -t 44  and t 45 -t 50 ) for which images are captured in partial regions including Nagasaki, Hiroshima, Kyoto, Shizuoka, Tokyo and Hokkaido, respectively. 
     Then, the sound acquiring section  262  determines the length of the image capturing period. For example, when the image captured in Nagasaki is selected by the image selection section  278 , the sound acquiring section  262  determines that the period (t 1 -t 10 ) for which images are captured in Nagasaki is relatively short and acquires the sound data for describing about Nagasaki from the explanation sound database  170 . Additionally, when the images captured in Nagasaki, Hiroshima, Kyoto, Shizuoka, Tokyo and Hokkaido are selected by the image selection section  278 , the sound acquiring section  262  determines that the period (t 1 -t 50 ) is relatively long and acquires the sound data of the detailed description about Japan as the sound data for describing about the image capturing regions from the explanation sound database  170 . 
     The sound acquiring section  262  calculates the rate of the period for which the image is captured in the specified partial region to the period for which the selected image is captured, and then acquires the sound data for describing about the specified partial region from the explanation sound data base  170  when the ratio is larger than a predetermined ratio. For example, when the image storage section  210  stores images captured in Nagasaki, Hiroshima, Kyoto, Tokyo and Hokkaido, the sound acquiring section  262  acquires the sound data about Kyoto from the explanation sound database  170  provided that the period for which the image is captured (t 64 -t 93 ) in Kyoto is more than half period of the total period for which the selected image is captured (t 51 -t 56 , t 57 - 63 , t 64 -t 93 , t 94 -t 97  and t 98 -t 10 ). Therefore, the output apparatus  140  can provide the sound for describing about the location at which the user  180  stayed particularly long time and captured the images to the user  180 . 
       FIG. 20  shows an example of a block configuration of an image capturing apparatus  600 . The image capturing apparatus  600  is another example of the image capturing apparatus  100  described with reference to  FIG. 15 .

     The image capturing section  602  captures images. Specifically, the image capturing section  602  receives light from a subject by an image capturing device such as a CCD to capture an image of the subject. Here, the image capturing section  602  may continuously capture the subject at a predetermined time interval. Then, the image capturing section  602  may hold a predetermined number of images which are continuously captured. The image capturing section  602  may determine the image captured at the timing proximate to the instructed image-capturing time among the images held in the image capturing section  602  as the captured image. 
     The display section  670  displays the image of light received by light receiving elements included in the image capturing section  602 . The mode setting section  692  sets the image capturing apparatus  600  to an image capturing mode in which the display section  670  displays an image or an non-image capturing mode in which the display section  670  does not display any image. 
     The recording section  650  records sounds surrounding the image capturing section  602 . Here, the recording section  650  records the sounds surrounding the image capturing section  602  in both of the case that the mode setting section  692  sets the image capturing mode and the case that the mode setting section  692  sets the non-image capturing mode. 
     The characteristic sound extraction section  694  extracts a predetermined kind of sound from the sounds recorded by the recording section  650 . For example, the characteristic sound extraction section  694  extracts music from the sounds recorded by the recording section  650 . In this case, the characteristic sound extraction section  694  extracts the fundamental frequency based on the fundamental frequency of the sound to determine the scale. Then, the characteristic sound extraction section  694  determines the amount of characteristic of music, such as rhythm, tempo and tonality based on the determined scale to extract note data. Additionally, the characteristic sound extraction section  694  may extract the chord progression of music based on the note data. 
     The condition storage section  660  previously store the condition to identify each kind of the environmental sounds extracted by the characteristic sound extraction section  694 . Specifically, the condition storage section  660  stores the characteristic frequency spectrum for each kind of the environmental sounds, such as a bark of dog, a bird call and sound of the waves. Then, the characteristic sound extraction section  694  extracts the environmental sound corresponding to the condition stored in the condition storage section  660  from the sounds recorded by the recording section  650 . For example, the characteristic sound extraction section  694  extracts the environmental sound corresponding to the frequency spectrum stored in the condition storage section  660  with more predetermined coincidence from the sounds recorded by the recording section  650 . Here, the condition sound extraction section  694  may store the environmental sound in itself for each kind thereof. In this case, the characteristic sound extraction section  694  may compares the environmental sound stored in the condition storage section  660  with the sound recorded by the recording section  650  and extract the environmental sound of which amount of characteristic (such as a frequency spectrum) corresponds to most the sound in the condition storage section  660  to determine the kind of the environmental sound. 
     The characteristic sound extraction section  694  extracts the predetermined kind of sound from the sounds recorded by the recording section  650  within a predetermined period since the image capturing section  602  captures the image. For example, the characteristic sound extraction section  694  extracts the music or the environmental sound from the sounds recorded by the recording section  650  within a predetermined period since the image capturing section  602  captures the image. Specifically, the characteristic sound extraction section  694  extracts the predetermined kind of sound from the sounds recorded by the recording section  650  within the preset period equal to or longer than the period for which the mode setting section  692  sets the image capturing mode. More specifically, the characteristic sound extraction section  694  extracts the music or the environmental sound from the sounds recorded by the recording section  650  within the preset period equal to or longer than the period for which the mode setting section  692  sets the image capturing mode.

Here, the sound acquiring section  696  extracts the play list ID stored as the play list information  792  in the music database  172  in association with the music ID for identifying the music acquired in S 920  or S 924 . Then, the sound acquiring section  696  selects a plurality of music IDs stored as the play list information  792  in the music database  172  in association with the extracted play list IDs, and acquires plural pieces of music identified by each of the plurality of selected music IDs from the music data table  791  stored in the music database  172 . Then, the data storage section  698  stores the plural pieces of music acquired by the sound acquiring section  696  in association with the images captured by the images capturing section  602  in order to simultaneously and continuously output the images and the plural pieces of music. Therefore, the image capturing apparatus  600  can record images and music in order that a series of pieces of music with the preferred combination are sequentially reproduced when the user  180  views the images. 
     Here, the sound acquiring section  696  previously stores the play list acquiring condition to acquire a plural pieces of music included in the play list. For example, the sound acquiring section  696  stores threshold sound volume which is the threshold value for the sound volume as the play list acquiring condition. Then, the sound acquiring section  696  may acquire the plural pieces of music included in the play list provided that the sound volume of the music extracted by the characteristic sound extraction section  694  is larger than the threshold sound volume previously stored in the sound acquiring section  696 . Additionally, the sound acquiring section may store low noise, selection frequency and recommendation degree as the play list acquiring condition. Specifically, the sound acquiring section  696  previously stores the threshold value for the magnitude of noise, and may acquire the plural pieces of music included in the play list provided that the characteristic sound extraction section  694  extracts the music having the amount of noise less than the threshold value. Here, the amount of noise may be a value derived based on the difference between the sound waveform data of the music acquired by the sound acquiring section  696  and the sound waveform data of the music extracted by the characteristic sound extraction section  694 . Additionally, the sound acquiring section  696  may extract the selection frequency or the recommendation degree stored as the music recommendation degree information  793  in the music database  172  in association with the acquired music and acquire the plural pieces of music included in the play list provided that the extracted selection frequency or recommendation degree is more than a predetermined reference value. 
     Here, the selection frequency may be an index indicative of the number of times at which the music acquired by the sound acquiring section  696  is selected. The image capturing apparatus  600  sends information indicating that the music is acquired to the music database  172 , and then, the music database  172  adds the selection frequency stored in the music recommendation degree information  793  in association with the acquired music. Additionally, the selection frequency may be an index indicative of the number of times at which the image capturing apparatus  600  reproduces the music when the image capturing apparatus  600  actually reproduces the music and the images. In this case, the selection frequency stored in the music recommendation degree information  793  is added in the image capturing apparatus every time the image capturing apparatus  600  reproduces the music. Here, the image capturing apparatus  600  may count the number of times at which the music is reproduced provided that the music is reproduced for a period longer than a predetermined length. For example, if the user  180  performs a fast-forward operation as soon as a music is reproduced, the image capturing apparatus  600  does not count the music as the reproduced music. Additionally, the sound acquiring section  696  may calculate the recommendation degree by itself based on the coincidence between the musical attribute, such as the favorite genre of the user  180 , the record company, the label, the composer, the songwriter, the arranger, the player and the broadcasting means such as a radio, a cable broadcast or programs, and that of the music acquired by the sound acquiring section  696 , and the hit degree. Here, each of the favorite attribute of the user  180  is previously stored in the image capturing apparatus  600 . 
     The sound acquiring section  696  may preferentially select the play list including more plural pieces of acquired music and acquire the plural pieces of music included in the selected play list when the sound acquiring section  696  acquires plural pieces of music in S 920  or S 924 . For example, the sound acquiring section  696  first preferentially selects the play list including all the acquired music. Additionally, the sound acquiring section  696  may preferentially select the play list including all the music which satisfy the above-described play list acquiring condition among the plural pieces of music acquired by the sound acquiring section  696  when the play list including all the acquired music is not stored in the play list information  792 . Additionally, the sound acquiring section  696  may calculate the ratio between the number of music included in the play list among the acquired music and the total number of music included in the play list and preferentially select the play list of which ratio is larger. 
     The sound acquiring section  696  previously stores the play list selection condition to select at least one of play list among a plurality of play lists when the music acquired in S 920  or S 924  is included in the plurality of play lists. For example, the sound acquiring section  696  stores the play list selection condition indicating that the play list should be selected based on the selection frequency at which the play list is selected, the number of music which satisfies the above-described play list acquiring condition and the recommendation degree of the play list. Then, the sound acquiring section  696  may preferentially select the play list of which the selection frequency stored in the play list information  792  is larger, the play list including more pieces of music which satisfy the play list acquiring condition and the play list of which recommendation degree stored in the play list information  792  is larger. Additionally, the sound acquiring section  696  may preferentially select the play list created by the play list creator who is more preferred by the user  180 . Here, the sound acquiring section  696  previously stores the preference degree of the user  180  regarding the play list creator for each play list creator ID. Then, the sound acquiring section  696  may preferentially select the play list associated with the play list creator ID which is more preferred by the user in the play list information  792 . 
     Now, it is described that the operation of the image capturing apparatus  600  when plural pieces of music included in the play list selected by the sound acquiring section  696  are stored along with images. The sound acquiring section  696  acquires the other music included in the selected play list provided that the sound acquiring section  696  detects that the music extracted by the characteristic sound extraction section  694  is changed. At this time, the sound acquiring section  696  may select the music having the information thereof stored in the play list information  792  that it should be reproduced next to the music acquired immediately before that. Additionally, the sound acquiring section  696  may preferentially select the music having higher recommendation degree calculated from the play list acquiring condition. Further, the sound acquiring section  696  may select the music at random. At this time, the sound acquiring section  696  may preferentially select the music having less selection frequency. Here, the sound acquiring section  696  may calculate the amount of change of the scene among a plurality of images captured by the image capturing section  602  and acquire the other music stored in the selected play list provided that the calculated amount of change of the scene is larger than a predetermined reference value. Additionally, the sound acquiring section  696  may calculate the amount of change of the scene based on various indexes such as the amount of change of the average luminance or the luminance distribution, the amount of change of the average luminance per color component or the luminance distribution per color component, or the amount of change of the object included in the image. 
     Here, the sound acquiring section  696  may select a new play list and acquire plural pieces of music included in the selected play list provided that the sound acquiring section  696  detects that the sound extracted by the characteristic sound extraction section  694  is changed, or that the scene among the plurality of images is changes. Additionally, the sound acquiring section  696  may select a new play list provided that the sound acquiring section  696  acquires the predetermined number of music and that are stored in the data storage section  698 . Additionally, the sound acquiring section  696  may select a new play list provided that the reproduction time of the music included in one play list which is continuously recorded on the data storage section  698  is longer than a predetermined reference value. Here, the sound acquiring section  696  may select a new play list based on the above-described play list selection condition. For example, the sound acquiring section  696  may preferentially select the play list having larger recommendation degree as the new play list. 
     The sound acquiring section  696  stores the determination condition to determine whether a new music is selected from the currently selected play list or a new play list is selected using a parameter being the change of music and the change of scene. Specifically, when the scene is changed, the sound acquiring section  696  stores the determination condition to select a new play list provided that the music is changed, and to select a new music among the currently selected play list provided that the music is not changed. Additionally, when the scene is not changed, the sound acquiring section  696  stores the determination condition to select a new music among the currently selected play list provided that the music is changed. Further, when both of the scene and the music are not changed, the sound acquiring section  696  stores the determination condition to select a new music in order to reproduce the new music at a timing allowing the same music to be continuously reproduced for a predetermined period. 
     The data storage section  698  may record a control signal indicating that the music to be reproduced is faded out at the timing before a switching timing at which a new music is reproduced by a predetermined time interval when plural pieces of music are stored in order to be continuously reproduced. Additionally, the data storage section  698  may record the control signal indicating that the new music is faded in for the period after the switching timing by a predetermined time interval. Further, the data storage section  698  may record the control signal indicating that the music reproduced before the switching timing and the music newly reproduced are cross-faded for a period with a predetermined time interval before and after the switching timing including the switching timing. 
     As described above, the image capturing apparatus  600  can select plural pieces of music in the play list including the music extracted from the environmental sound and reproduce the same along with the images. Therefore, the image capturing apparatus  600  can reproduce a series of music which are the music related to the environmental sound at capturing the image and which are preferred by the user  180  along with the images. 
     Hereinbefore, the operation that the sound acquiring section  696  acquires music from the music database  172  with reference to  FIGS. 21 to 23 . Additionally the sound acquiring section  696  can acquire environmental sounds through an operation same as the above. Further, the sound acquiring section  696  can various kinds of sounds which should be recorded in association with the images in addition to the music and the environmental sound, of course. 
       FIG. 24  shows an example of a block configuration of an output apparatus  1040 . The output apparatus  1040  may be another example of the output apparatus  140  included in the sound provision system. Here, the image capturing apparatus  100  transmits the time at which the sound surrounding thereof is recorded in addition to the captured image and the surrounding sound at the image-capturing. 
     The output apparatus  140  includes an image storing section  1010 , an output section  1024 , a sound acquiring section  1096 , a characteristic sound extraction section  1094 , a condition storage section  1060 , a sound storage section  1020 , an allowed time setting section  1043 , an output time detection section  1044  and an output request acquiring section  1048 . 
     The image storage section  1010  stores the image captured by the image acquiring section  100 . The image storage section stores the time at which the image is captured in association with the image. 
     The sound storage section  1020  stores the sound recorded by the image capturing section  100 . The sound storage section  1020  stores the time at which the sound is recorded in association with the sound. Specifically, the sound storage section  1020  stores the sound surrounding the image capturing apparatus  100 . Here, the recording time may be a time at which the recording is started and may be a time at which the recording is terminated. 
     The characteristic sound extraction section  1094  extracts a predetermined kind of sound from the sounds stored in the sound storage section  1020 . Specifically, the sound acquiring section  1096  acquired the sound of which kind is same as the sound extracted by the characteristic sound extraction section  1094 . For example, the characteristic sound extraction section  1094  extracts the sound from the sounds stored in the sound storage section  1020 . Then, the sound acquiring section  1096  acquires the music of which kind is same as that of the sound extracted by the characteristic sound extraction section  1094 . Additionally, the sound acquiring section  1096  acquires the environmental sound of which kind is the same as that of the environmental sound extracted by the characteristic sound extraction section  1094 . Here, the concrete operation that the sound acquiring section  1096  acquires a sound or an environmental sound is same as the operation of the sound acquiring section  696  described above with reference to  FIG. 9 , so that the description is omitted. 
     The output request acquiring section  1048  acquires a request for outputting the image stored in the image storage section  1010 . The allowed time setting section  1043  sets an allowed time which is the period for which a sound is captured to be longer when the difference between the time at which the output request acquiring section  1048  acquires the output request and the image capturing time of the image stored in the image storage section  1010  is larger. Then, the characteristic sound extraction section  1094  extracts the music from the sounds recorded within a predetermined allowed time since the image is captured. The output section  1024  synchronously outputs the sound acquired by the sound acquiring section  1096  and the image stored in the image storage section  1010 . Specifically, the output section  1024  synchronously outputs the music or environmental sound acquired by the sound acquiring section  1096  and the image stored in the image storage section  1010 . 
     The output apparatus  1040  according to the present embodiment can provide the captured image along with the sound put on at the time at which the image was captured, such as the popular music at that time to the user  180 . 
       FIG. 25  shows an example of an allowed time set by the allowed time setting section  1043 . For example, on receiving from the user  180  at a time t 13  an instruction on outputting the image captured at a time t 12 , the allowed time setting section  1043  determines a tolerance Δt 52  for which the characteristic sound extraction section  1094  extracts music base on a difference between the time at which the instructed output time and the time at which the image to be outputted is captured (t 13 -t 12 ). Then, the characteristic sound extraction section  1094  extracts the music from the sound recorded within the time range before/after the time t 12  by the Δt 52  (the time t 12 −Δt 52 ˜the time t 12 +Δt 52 ) among the sounds stored in the sound storage section  1020 . 
     Here, the characteristic sound extraction section  1094  may extracts the sound from the sounds recorded within a period from a time before the time t 12  by theΔt 52  to the time t 12 . Alternatively, the characteristic sound extraction section  1094  may extracts the sound from the sounds recorded within a period from the time  12  to a time after the time t 12  by theΔt 52 . 
     Additionally, the allowed time setting section  1043  sets the allowed time to be larger in proportion to the magnitude of the difference between the time at which the captured image stored in the image storage section  1010  is captured and the time at which the instruction on outputting is received. In  FIG. 25 , the allowed time setting section  1043  sets a tolerance Δt 51  longer than the tolerance Δt 52  when it receives at a time t  13  the instruction on outputting the image captured at a time t 11  before the time t 12 . Then, the characteristic sound extraction section  1094  extracts music from the sound recorded within the time range from the time (t 11 −Δt 51 ) to the time (t 11 +Δt 51 ). 
     Here, the allowed time setting section  1043  may set a period obtained by dividing the period between the time at which the image is captured and the time at which the instruction on outputting is received by the predetermined number. In this case, the characteristic sound extraction section  1094  extracts music from the sound recorded before/after one day of the time at which the image is captured when the image captured ten days ago is outputted. Additionally, the sound extraction section  1094  extracts music from the sound recorded before/after one year of the time at which the image is captured when the image captured ten years ago is outputted. 
     As thus described above, the output apparatus  1040  can appropriately determine the music put on the location at which user  180  visited, such as a music in the car and a music of the cable broadcast in the souvenir shop in the sightseeing spot and download the music to reproduce along with the images. Additionally, the output apparatus  1040  can download the environmental sound of which kind is same as the environmental sound in the location at which the user  180  visited to reproduce along with the images. Further, the output apparatus  1040  selects the sound including the music and the environmental sound among the sounds recorded within wider time range including the time at which the images were captured when the images captured at the relatively past are outputted. Therefore, the user  180  can enjoyably appreciate the images as remembering the music which is the most popular music at that time. 
       FIG. 26  shows an example of the hardware configuration of a computer  1500  involved in the image capturing apparatus  100  and the output apparatus  140 .

The ROM  1510  stores a boot program executed by the computer  1500  at activating and a program depending on the hardware of the computer  1500 . The flexible disk drive  1550  reads the program or data from a flexible disk  1590  and provides the same to the hard disk drive  1540  and the communication interface  1530  through the RAM  1520 . The input/output chip  1570  connects various input/output units through the flexible disk drive  1550  and such as a parallel port, a serial port, a keyboard port and a mouse port. 
     The program provided to the communication interface  1530  through the RAM  1620  is stored in a recording medium, such as the flexible disk  1590 , the CD-ROM  1595 , or an IC card and provided by the user. The program is read from the recording medium, provided to the communication interface  1530  through the RAM  1520  and transmitted to the output apparatus  140  through the network. Then the program transmitted to the output apparatus  140  is installed in the output apparatus  140  and executed. 
     The program installed and executed in the output apparatus  140  operates the image capturing apparatus  100  as described above with reference to  FIG. 1-FIG .  14 . Additionally, the program installed and executed in the image capturing apparatus  100  operates the image capturing apparatus  100  as described above with reference to  FIG. 1-FIG .  14 . 
     The above-described program may be stored in an external storage medium.
