         [0004]    It is desirable to view a large number of images more easily. 
         [0005]    According to an exemplary image display control apparatus embodiment, the apparatus includes a detector that detects an object being in proximity to a display; the display; and a controller that changes from a first image to a second image in response to a movement of the object that remains in proximity to the display. 
         [0006]    According to one aspect of the apparatus, the detector also detects a touch of the object to the display, and the controller processes the touch differently than the object being in proximity to the display. 
         [0007]    According to another aspect of the apparatus, the detector detects multiple touches of the object to the display as a tapping operation. 
         [0008]    According to another aspect of the apparatus, the controller responds to the detector detecting the object remaining in proximity to the display while the object moves a predetermined lateral distance over a surface of the display by scrolling the first image off the display while scrolling the second image on the display. 
         [0009]    According to another aspect of the apparatus, the detector detects a last lateral speed of the object, and the controller performs a proximity flick operation when the last lateral speed of the object is less than a predetermined threshold, the proximity flick operation performs scroll animation of the second image on the display. 
         [0010]    According to another aspect of the apparatus, the controller determines if a lateral movement amount of the object while remaining in proximity to the display is less than a predetermined threshold, and when less, the controller returns the first image to an initial position on the display before the detector detected the object being in proximity. 
         [0011]    According to another aspect of the apparatus, the controller determines if a lateral movement amount of the object while remaining in proximity to the display is more than a predetermined threshold, and when more, the controller scrolls the second image on the display. 
         [0012]    According to another aspect of the apparatus, the controller is configured to display a menu when in a proximity flicking operation mode, and jumps to a predetermined image in an ordered set of stored images so the predetermined image is displayed when the object is detected as performing a proximity flicking movement. 
         [0013]    According to another aspect of the apparatus, the ordered set of stored images are ordered by at least one of date and a storage folder. 
         [0014]    According to another aspect of the apparatus, the controller displays a proximity menu when a time that the object remains in proximity exceeds a predetermined threshold time. 
         [0015]    According to another aspect of the apparatus, the controller displays the proximity menu in accordance with a position of the object with respect to the display. 
         [0016]    According to another aspect of the apparatus, the controller deletes the proximity menu when a latest speed of the object when moved away from the display is less than a predetermined threshold speed. 
         [0017]    According to another aspect of the apparatus, the controller determines the object performs a proximity flicking movement when a latest speed of the object when moved away from the display is greater than a predetermined threshold speed, and the controller performs a scroll animation of the second image on the display that corresponds with a content of the proximity menu. 
         [0018]    According to another aspect of the apparatus, an electrostatic touch panel that includes the detector and the display. 
         [0019]    According to another aspect of the apparatus, the controller performs scroll animation of the first image and the second image with a first effect in response to the touch and with a second effect in response to the object being in proximity to the display. 
         [0020]    According to another exemplary image display control apparatus embodiment, the apparatus includes a detector that detects an object being in proximity to a display; the display; and a controller that responds to a change in a proximity of the object by changing from a first image to a second image, the second image being selected from a plurality of images stored in a predetermined order. 
         [0021]    According to one aspect of the apparatus, the detector also detects a touch of the object to the display, and the controller processes the touch differently than the object being in proximity to the display.

     DETAILED DESCRIPTION OF EMBODIMENTS 
     Configuration Example of Image Pickup Apparatus 
       [0035]      FIG. 1  is a block diagram illustrating a configuration of an image pickup apparatus serving as an image display control apparatus according to an embodiment of the present disclosure. 
         [0036]    An image pickup apparatus  1  shown in  FIG. 1  includes a lens unit  11  to a RAM  27 . 
         [0037]    The lens unit  11  includes a photographing lens, an aperture, a focus lens, and the like. On an optical path of object light which emitted through the lens unit  11 , an image pickup element  12  such as a CCD (Change Coupled Device) sensor is disposed. 
         [0038]    The image pickup element  12 , an analog signal processor  13 , an A/D (Analog/Digital) converter  14 , and a digital signal processor  15  are connected in this order. 
         [0039]    Furthermore, a display unit  17  and a recording device  19  are connected to the digital signal processor  15 . A touch panel  16  is disposed on an image display screen of the display unit  17 . The touch panel  16  and the display unit  17  constitute a touch screen  18 . The display unit  17  includes a liquid crystal display (LCD) or the like. 
         [0040]    To the lens unit  11 , an actuator  20  used to control the aperture included in the lens unit  11  and move the focus lens included in the lens unit  11  is connected. To the actuator  20 , a motor driver  21  is also connected. The motor driver  21  controls driving of the actuator  20 . 
         [0041]    A CPU (Central Processing Unit)  23  controls the entire image pickup apparatus  1 . Therefore, the analog signal processor  13 , the A/D converter  14 , the digital signal processor  15 , the motor driver  21 , a TG (Timing Generator)  22 , an operation unit  24 , an EEPROM (Electrically Erasable Programmable ROM)  25 , a program ROM (Read Only Memory)  26 , the RAM (Random Access Memory)  27 , and the touch panel  16  are connected to the CPU  23 . 
         [0042]    The touch panel  16  which is an electrostatic touch panel, for example, detects tapping (touch) performed on the touch panel  16  and outputs information on a tapped position on the touch panel  16  to the CPU  23 . Furthermore, the touch panel  16  may detect the user&#39;s finger approaching the touch panel  16  within a predetermined distance (hereinafter referred to as “proximity”, where appropriate) according to change (a level) of electrostatic capacitance even though the user&#39;s finger has not yet touched the touch panel  16 . A distance within which the touch panel  16  may detect the proximity is a distance within approximately 20 mm from the screen. Within a distance of 10 mm, a position on the touch panel  16  to which the finger comes close may be recognized. Note that a target of detection of contact or proximity using the touch panel  16  is not limited to a user&#39;s finger, but similar dielectric object may be detected. Hereinafter, it is assumed that a user&#39;s finger is to be detected. 
         [0043]    The user may perform a dragging operation and a flicking operation by touching the touch panel  16  or bringing the finger close to the touch panel  16 . The CPU  23  which obtains a signal from the touch panel  16  may detect such a user&#39;s operation. 
         [0044]    The dragging operation and the flicking operation are the same as each other in terms of an operation of tracing a plane which is parallel to the touch panel  16 . However, the dragging operation and the flicking operation are different from each other in that when the dragging operation is performed, a speed of the finger which moves (or which is immediately before moving) away from the plane is low (not larger than a predetermined value) whereas when the flicking operation which is an operation of flick is performed, a speed of the finger which moves (or which is immediately before moving) away from the plane is high (larger than the predetermined value). In other words, the dragging operation is an operation of stopping a movement of the finger which is performing tracing and moving the finger upward away from the traced plane whereas the flicking operation is an operation of moving the finger which is performing tracing laterally away from the traced plane while a speed of the movement is maintained. 
         [0045]    The recording device  19  is constituted by a removable recording medium including an optical disc such as a DVD (Digital Versatile Disc) and a semiconductor memory such as a memory card. The recording device  19  records a (signal of) image obtained through image capturing. The recording device  19  is detachable from a body of the image pickup apparatus  1 . 
         [0046]    The EEPROM  25  stores various set information. The EEPROM  25  further stores other information such as information to be held even when a power source is brought to an off state. 
         [0047]    The program ROM  26  stores programs to be executed by the CPU  23  and data used to execute the programs. 
         [0048]    The RAM  27  serving as a work area temporarily stores programs and data used when the CPU  23  executes various processes. 
         [0049]    Hereinafter, entire operation of the image pickup apparatus  1  of the configuration in  FIG. 1  will be briefly described. 
         [0050]    The CPU  23  controls the various units included in the image pickup apparatus  1  by executing the programs recorded in the program ROM  26 . Then, the CPU  23  executes predetermined processes including an image capturing process and a process of controlling display of an image in the display unit  17  in accordance with a signal supplied from the touch panel  16  or a signal supplied from the operation unit  24 . 
         [0051]    The operation unit  24  is operated by the user and supplies a signal corresponding to the operation to the CPU  23 . The operation unit  24  includes a zoom lever (TELE/WIDE)  41  and a shutter button  42  which will be described hereinafter with reference to  FIG. 2 , for example. 
         [0052]    When the actuator  20  is driven, the lens unit  11  is exposed from or accommodated in a case of the image pickup apparatus  1 . Furthermore, when the actuator  20  is driven, the aperture included in the lens unit  11  is controlled and the focus lens included in the lens unit  11  is moved. 
         [0053]    The TG  22  supplies a timing signal to the image pickup element  12  under control of the CPU  23 . In accordance with the timing signal, an exposure time and the like in the image pickup element  12  are controlled. 
         [0054]    The image pickup element  12  operates in response to the timing signal supplied from the TG  22  so as to receive object light incident through the lens unit  11  and perform photoelectric conversion. Then, the image pickup element  12  supplies an analog image signal corresponding to an amount of the received light to the analog signal processor  13 . Here, the motor driver  21  drives the actuator  20  under control of the CPU  23 . 
         [0055]    The analog signal processor  13  performs an analog signal process such as amplification on the analog image signal supplied from the image pickup element  12  under control of the CPU  23 . A resultant analog image signal is supplied from the analog signal processor  13  to the A/D converter  14 . 
         [0056]    The A/D converter  14  performs A/D conversion on the analog image signal supplied from the analog signal processor  13  under control of the CPU  23 . A resultant digital image signal is supplied from the A/D converter  14  to the digital signal processor  15 . 
         [0057]    The digital signal processor  15  performs a digital signal process such as a noise removal process on the digital image signal supplied from the A/D converter  14  under control of the CPU  23 . The digital signal processor  15  causes the display unit  17  to display an image corresponding to the digital image signal. 
         [0058]    Furthermore, the digital signal processor  15  performs compression encoding on the digital image signal supplied from the A/D converter  14  in accordance with a predetermined compression encoding method such as JPEG (Joint Photographic Experts Group). The digital signal processor  15  causes the recording device  19  to record the digital image signal which has been subjected to the compression encoding. 
         [0059]    The digital signal processor  15  also reads the digital image signal which has been subjected to the compression encoding from the recording device  19  and performs decompression decoding in accordance with a decompression decoding method corresponding to the predetermined compression encoding method. The digital signal processor  15  causes the display unit  17  to display an image corresponding to the digital image signal. 
         [0060]    In addition, the digital signal processor  15  generates an image of an AF (auto focus) frame used to fulfill an AF function and an image of a menu button under control of the CPU  23  and causes the display unit  17  to display the images. 
         [0061]    The image captured by the image pickup element  12  is displayed in the display unit  17 . In this case, the AF frame is set on the image displayed in the display unit  17 . In accordance with an image included in the AF frame, focus control is performed. 
         [0062]    As described above, the image pickup apparatus  1  has the AF function. The image pickup apparatus  1  further has an AE (Automatic Exposure) function and an AWB (Auto White Balance) function. These functions are realized when the CPU  23  reads and executes programs stored in the program ROM  26 . Furthermore, the AF function, the AE function, and the AWB function are merely examples of functions included in the image pickup apparatus  1 . That is, the image pickup apparatus  1  has various functions relating to photographing. 
         [0063]      FIGS. 2A and 2B  are perspective views illustrating configurations of appearances of the image pickup apparatus  1  shown in  FIG. 1 . 
         [0064]    Note that, among planes of the image pickup apparatus  1 , a plane which faces an object when the user captures the object, that is, a plane including the lens unit  11  disposed thereon is referred to as a “front face”. On the other hand, among the planes of the image pickup apparatus  1 , a plane which faces the user when the user captures the object, that is, a plane positioned opposite to the front face is referred to as a “rear face”. Furthermore, among the planes of the image pickup apparatus  1 , a plane located on an upper side and a plane disposed on a lower side when the user captures the object are referred to as an “upper face” and a “lower face”, respectively. 
         [0065]      FIG. 2A  is a perspective view illustrating a configuration of an appearance of the front face of the image pickup apparatus  1  shown in  FIG. 1 .  FIG. 2B  is a perspective view illustrating a configuration of an appearance of the rear face of the image pickup apparatus  1 . 
         [0066]    The front face of the image pickup apparatus  1  may be covered by a lens cover  47 . When the lens cover  47  is opened downward in the drawing, a state shown in  FIG. 2A  is obtained. As shown in  FIG. 2A , an upper portion of the front face in which the lens cover  47  is removed includes a photographing lens  45  and an AF illuminator  46  included in the lens unit  11  in this order from the right side. 
         [0067]    The AF illuminator  46  also serves as a self-timer lamp. The upper face of the image pickup apparatus  1  includes the zoom lever (TELE/WIDE)  41 , the shutter button  42 , a reproducing button  43 , and a power button  44  arranged thereon in this order from the left side of  FIG. 2A . The zoom lever  41 , the shutter button  42 , the reproducing button  43 , and the power button  44  are included in the operation unit  24  shown in  FIG. 1 . 
         [0068]    As shown in  FIG. 2B , the touch screen  18  is disposed on the entire rear face of the image pickup apparatus  1 . 
         [0069]    In the touch screen  18 , an image captured by the image pickup element  12  is displayed in a photographing mode for capturing an object whereas an image recorded in the recording device  19  is displayed in a reproducing mode for displaying an image which has been captured. In addition, in the touch screen  18 , a menu button used to set (change) various setting items of the image pickup apparatus  1 , a list display button used to display a list of a plurality of images which have been stored, a deletion button used to delete a displayed image, and a photographing mode button used to enter the photographing mode are displayed as GUIs (Graphical User Interfaces). 
       Image Display Control in First Embodiment 
       [0070]    Next, a first display control performed by the image pickup apparatus  1  (CPU  23 ) which is image display control according to a first embodiment of the present disclosure will be described. 
         [0071]    In the image pickup apparatus  1 , a captured image which is read from the recording device  19  and which is displayed in the display unit  17  may be scrolled by performing an operation of touching and tracing the touch screen  18  by a finger of the user (a dragging operation and a flicking operation) in the reproducing mode. Furthermore, in the image pickup apparatus  1 , as with the operation of touching and tracing the touch screen  18 , by performing an operation of bringing a finger of the user close to the touch screen  18  and tracing the touch screen  18 , a captured image may be scrolled. 
       Example of Screen in First Display Control 
       [0072]      FIG. 3  shows a state in which the user&#39;s finger is brought close to the touch screen  18  in the reproducing mode. 
         [0073]    A captured image P 1  is displayed at the center of the display screen in the reproducing mode. A menu button M 1 , a calendar display button M 2 , a list display button M 3 , a slide-show button M 4 , and a deletion button M 5  are displayed in a left-end region of the display screen and a wide-zoom button M 6  and a photographing mode button M 7  are displayed in a right-end region of the display screen (as images). When the user&#39;s finger is merely brought close to the touch screen  18 , the display screen is not changed. 
         [0074]      FIG. 4  shows a display screen in a state in which the user&#39;s finger brought close to the touch screen  18  as shown in  FIG. 3  is laterally (rightward) moved while a proximity state is maintained. 
         [0075]    The image pickup apparatus  1  (CPU  23 ) detects the movement of the user&#39;s finger in the detected proximity state by a certain distance or more. Then, in the image pickup apparatus  1 , the captured image P 1  which is disposed at the center of the display screen is scrolled in accordance with the movement of the finger. As shown in  FIG. 4 , when the captured image P 1  is scrolled rightward, a portion of a captured image P 2  which is to be displayed next is displayed in the left side of the captured image P 1 . 
         [0076]    The relationship between the captured images P 1  and P 2  will be described. In the recording device  19 , a plurality of captured images obtained through image capturing performed by the image pickup apparatus  1  are recorded. In the image pickup apparatus  1 , the captured images are displayed one by one forward or backward in a predetermined order such as in order of captured date, in order of file names (alphanumeric characters), or in order of arrangement in the recording device  19 . The captured image P 2  is displayed after the captured image P 1  in order of display of the captured images forward or backward. 
         [0077]      FIG. 5  shows a display screen displayed after the user&#39;s finger is further moved from the state shown in  FIG. 4  and moved away from the touch screen  18  while a speed of the movement is not lowered. That is,  FIG. 5  shows a display screen displayed after the flicking operation (proximity flicking operation) is performed by the user&#39;s finger which is in the proximity state. 
         [0078]    The image pickup apparatus  1  detects the speed at the time when the user&#39;s finger in the proximity state is moved away from the touch screen  18 . Since the speed is equal to or larger than a predetermined threshold value, the image pickup apparatus  1  determines that the proximity flicking operation has been performed. Then, the image pickup apparatus  1  displays the entire captured image P 2  to be displayed next which is displayed when the captured image P 1  is scrolled rightward as shown in  FIG. 4 . That is, the captured image P 1  shown in  FIG. 3  is replaced by the captured image P 2 . Here, in the display screen, the captured image P 2  is also scrolled along with the rightward scroll of the captured image P 1 , and the captured image P 2  is displayed as scroll animation gradually from a right portion of the captured image P 2 . 
       Flowchart of First Display Control 
       [0079]      FIG. 6  is a flowchart illustrating a process of the first display control described with reference to  FIGS. 3 to 5 . 
         [0080]    First, in step S 1 , the image pickup apparatus  1  determines whether touch or proximity of the user&#39;s finger relative to the touch panel  16  is detected. 
         [0081]    The process in step S 1  is repeatedly performed until the touch or the proximity of the user&#39;s finger is detected. Then, when it is determined that the touch of the user&#39;s finger is detected in step S 1 , the process proceeds to step S 2  where the image pickup apparatus  1  executes a predetermined process (tapping process) corresponding to the touch of the finger. Thereafter, the process returns to step S 1 . 
         [0082]    On the other hand, when it is determined that the proximity of the user&#39;s finger is detected in step S 1 , the process proceeds to step S 3  where the image pickup apparatus  1  determines whether a movement of the finger detected as a proximity state is detected. When it is determined that the movement of the finger is not detected in step S 3 , the process returns to step S 1 . 
         [0083]    On the other hand, when it is determined that the movement of the finger is detected in step S 3 , the process proceeds to step S 4  where the image pickup apparatus  1  determines whether the finger moves from a first proximity detection position by a distance DS or more. When it is determined that the finger does not move from the first proximity detection position by the predetermined distance DS or more, the process returns to step S 1 . 
         [0084]    On the other hand, when it is determined that the finger moves from the first proximity detection position by the predetermined distance DS or more in step S 4 , the process proceeds to step S 5  where the image pickup apparatus  1  scrolls a captured image in accordance with the movement of the finger detected as the proximity state. 
         [0085]    Then, in step S 6 , the image pickup apparatus  1  determines whether the finger detected as the proximity state moves away from the screen. When it is determined that the finger detected as the proximity state does not move away from the screen in step S 6 , the process returns to step S 5  where the captured image is scrolled in accordance with a movement of the finger. 
         [0086]    On the other hand, when it is determined that the finger detected as the proximity state moves away from the screen in step S 6 , the process proceeds to step S 7  where the image pickup apparatus  1  determines whether the latest speed of the finger (speed immediately before the finger moves away from the screen) is equal to or larger than a predetermined threshold value THa. 
         [0087]    When it is determined that the latest speed of the finger is equal to or larger than the predetermined threshold value THa in step S 7 , the process proceeds to step S 8  where the image pickup apparatus  1  determines that the proximity flicking operation is performed and performs scroll animation is performed to display the next captured image. 
         [0088]    On the other hand, when it is determined that the latest speed of the finger is smaller than the predetermined threshold value THa in step S 7 , the process proceeds to step S 9  where the image pickup apparatus  1  determines whether a sum of movements of the finger from the first proximity detection position to a position in which the finger moves away is equal to or larger than a predetermined threshold value THb. That is, it is determined whether a movement distance of the finger from the first proximity detection position to the position in which the finger moves away is equal to or larger than the predetermined threshold value THb. 
         [0089]    When it is determined that the sum of the movement amounts of the finger is equal to or larger than the predetermined threshold value THb in step S 9 , the process proceeds to step S 10  where the image pickup apparatus  1  determines that a proximity dragging operation has been performed and perform scroll animation to display the next captured image. 
         [0090]    On the other hand, when it is determined that the sum of the movement amounts of the finger is smaller than the predetermined threshold value THb in step S 9 , the process proceeds to step S 11  where the image pickup apparatus  1  performs scroll animation so that the scrolled captured image is restored to the center of the screen (a position located before the proximity dragging operation is started). 
         [0091]    After the processes in step S 8 , S 10 , and S 11 , the process returns to step S 1  and the processes following the process of step S 1  are executed again. 
         [0092]    The first display control process described above is executed until the power of the image pickup apparatus  1  is turned off. 
         [0093]    As described above, according to the first display control of the present disclosure, as with the case of a touch operation, the user may perform scroll display of the captured images by bringing the finger close to the touch screen  18  and performing tracing (a dragging operation or a flicking operation). In this case, since the finger does not contact the touch screen  18 , airy operational feeling can be attained. Furthermore, since the touch screen  18  is not touched, a failure rate of a user&#39;s operation may be reduced and finger prints and dirt are prevented from being attached due to the touch operation. 
         [0094]    Note that, in the foregoing example, the image pickup apparatus  1  performs the scroll animation by the proximity-and-tracing operation similarly to the case of the touch-and-tracing operation. However, different effects of the scroll animation may be attained (scroll states may be switched from one to another) between the proximity operation and the touch operation. For example, scroll speeds may be different and the numbers of fed images may be different between the proximity operation and the touch operation. More specifically, the scroll speed of the proximity operation may be higher than the scroll speed of the touch operation, or the number of the fed images may be determined such that images are fed one by one in the touch operation and images are fed in a unit of several images, for example. Since different processes are performed between the proximity operation and the touch operation, a more number of operations may be performed. 
       Image Display Control in Second Embodiment 
       [0095]    Next, second display control performed by the image pickup apparatus  1  (CPU  23 ) which is image display control according to a second embodiment of the present disclosure will be described. The second display control of the image pickup apparatus  1  is attained by adding a certain function to the first display control described above. 
         [0096]    Specifically, when a proximity holding operation performed by the user is detected, an operation menu which is different from those of a normal proximity dragging operation and a normal proximity flicking operation is displayed. The proximity holding operation is an operation of holding a state in which the user&#39;s finger is located in a certain position close to the recording device  19  for a predetermined period of time. 
       Example of Screen in Second Display Control 
       [0097]      FIG. 7  shows an example of display of the operation menu displayed when the proximity holding operation performed by the user is detected. 
         [0098]    In the example shown in  FIG. 7 , unlike menus of the normal proximity dragging operation and the normal proximity flicking operation, a menu Q 1  is displayed to jump to a captured image positioned hundred images forward or backward in a predetermined order when the proximity flocking operation is performed. When the user performed the proximity flicking operation rightward or leftward, a captured image positioned a hundred images forward or backward in a predetermined order is displayed after scrolling, that is, scroll animation is executed. 
         [0099]    Note that, although a captured image positioned a hundred images forward or backward is displayed by jumping as content of a menu in the example shown in  FIG. 7 , the content of the menu displayed by performing the proximity holding operation may be appropriately determined. For example, a jump to a captured image having a date before or after an image of interest or a jump to a captured image included in a different folder may be displayed. Furthermore, the user may select (determine) a menu to be displayed in a setting screen. 
       Flowchart of Second Display Control 
       [0100]      FIG. 8  is a flowchart illustrating second display control performed by the image pickup apparatus  1  (CPU  23 ). 
         [0101]    As described above, the second display control is obtained by newly adding functions to the first display control and is the same as the process shown in  FIG. 6  except for a portion relating to the additional functions. More specifically, the second display control is the same as the process shown in  FIG. 6  except that processes in step S 25  and step S 26  are added. Step S 21  to step S 24  and step S 27  to step S 33  shown in  FIG. 8  correspond to step S 1  to step S 4  and step S 5  to step S 11  shown in  FIG. 6 , respectively. Therefore, descriptions other than descriptions of the processes associated with step S 25  and step S 26  which are newly added are omitted. 
         [0102]    When it is determined that a movement of the finger in the proximity state is detected in step S 23 , the process proceeds to step S 24 . On the other hand, when it is determined that a movement of the finger in the proximity state is not detected in step S 23 , the process proceeds to step S 25 . Furthermore, also when it is determined that the finger in the proximity state has not moved from the proximity detection position obtained at the beginning by a predetermined distance DS or more, the process proceeds to step S 25 . Specifically, when it is determined that the finger has not substantially moved from the beginning proximity detection position, the process in step S 25  is performed. 
         [0103]    In step S 25 , the image pickup apparatus  1  determines whether a predetermined period of time DT has elapsed after first proximity detection. When it is determined that the predetermined period of time DT has not elapsed after the first proximity detection in step S 25 , the process returns to step S 21 . 
         [0104]    On the other hand, when it is determined that the predetermined period of time DT has elapsed after the first proximity detection, the process proceeds to step S 26  where the image pickup apparatus  1  executes a proximity menu display process. After the proximity menu display process is performed, the process returns to step S 21 . 
         [0105]    Referring now to a flowchart shown in  FIG. 9 , the proximity menu display process performed in step S 26  will be described in detail. 
         [0106]    First, in step S 51 , the image pickup apparatus  1  causes the touch screen  18  to display a menu in accordance with a position of the finger detected as the proximity state. 
         [0107]    Then, the image pickup apparatus  1  detects a subsequent state of the user&#39;s finger detected as the proximity state. Specifically, the image pickup apparatus  1  determines whether the finger detected as the proximity state is in a touch state, holds the proximity state, or is moved away. 
         [0108]    When it is determined that the touch of the user&#39;s finger detected as the proximity state is detected in step S 52 , the process proceeds to step S 53  where the image pickup apparatus  1  executes a predetermined process (tapping process) corresponding to the touch of the finger. Thereafter, the process returns to step S 21 . 
         [0109]    On the other hand, when it is determined that the proximity state of the finger is held in step S 52 , the process proceeds to step S 54  where the image pickup apparatus  1  determines whether the user&#39;s finger moves from the first proximity detection position by the distance DS or more. When it is determined that the finger does not move from the first proximity detection position by the predetermined distance DS or more, the process returns to step S 52 . 
         [0110]    On the other hand, when it is determined that the finger moves from the first proximity detection position by the predetermined distance DS or more in step S 54 , the process proceeds to step S 55  where the image pickup apparatus  1  scrolls a captured image in accordance with the movement of the finger detected as the proximity state. 
         [0111]    Specifically, in the processes in step S 54  and step S 55 , when the proximity of the user&#39;s finger is detected, the menu is displayed, and the finger moves, the captured image is scrolled as with the case of the normal proximity dragging operation. 
         [0112]    On the other hand, when it is determined that the finger detected as the proximity state moves away in step S 52 , the process proceeds to step S 56 . Then, in step S 56 , the image pickup apparatus  1  determines whether the latest speed of the finger (a speed immediately before the finger moves away from the screen) is equal to or larger than a predetermined threshold value THa. 
         [0113]    When it is determined that the latest speed of the finger is smaller than the threshold value THa in step S 56 , the process proceeds to step S 57  where the image pickup apparatus  1  deletes the menu displayed in step S 51 . 
         [0114]    On the other hand, when it is determined that the latest speed of the finger is equal to or larger than the threshold value THa in step S 56 , the process proceeds to step S 58  where the image pickup apparatus  1  determines that a proximity flicking operation has been performed and performs scroll animation for a captured image corresponding to content of the displayed menu. 
         [0115]    In step S 56  to step S 58 , when the user gradually moves away the finger in the proximity state, it is determined that a menu cancel operation is to be performed and the menu is deleted. When the proximity flicking operation is performed, scroll animation for a captured image corresponding to content of the menu. 
         [0116]    After step S 57  or step S 58 , the process returns to step S 21  shown in  FIG. 8 . 
         [0117]    In the second display control process described above, in addition to the function of the first display control, a proximity flicking operation which is different from the normal proximity flocking operation becomes available in a state in which the proximity is held in a certain position of the touch screen  18 . Since a plurality of operations may be performed by the proximity flicking operation and a more number of operations may be performed. Accordingly, operability is improved. 
         [0118]    As described above, since the image pickup apparatus serving as the image display control apparatus according to the embodiment of the present disclosure has the scroll animation function corresponding to a proximity operation and a tracing operation, a large number of captured images recorded in the recording device  19  may be more easily viewed. 
       Example of Configuration of Computer 
       [0119]    The series of processes described above may be executed by hardware or software. 
         [0120]    In this case, it is apparent that the image pickup apparatus  1  shown in  FIG. 1  may execute the series of processes, and alternatively, a personal computer shown in  FIG. 10  may execute the series of processes. 
         [0121]    In  FIG. 10 , a CPU  101  executes various processes in accordance with programs stored in a ROM (Read Only Memory)  102  and programs loaded in a RAM (Random Access Memory)  103  from a storage unit  108 . The RAM  103  also stores data used to execute the various processes by the CPU  101  where appropriate. 
         [0122]    The CPU  101 , the ROM  102 , and the RAM  103  are connected to one another through a bus  104 . Furthermore, an input/output interface  105  is also connected to the bus  104 . 
         [0123]    To the input/output interface  105 , an input unit  106  including a keyboard and a mouse, an output unit  107  including a touch panel display and a speaker, the storage unit  108  including a hard disk, and a communication unit  109  including a modem and a terminal adapter are connected. The communication unit  109  controls communication with another apparatus (not shown) through a network such as the Internet. 
         [0124]    To the input/output interface  105 , a drive  110  is also connected where appropriate, and a removable medium  111  such as a magnetic disk, an optical disc, a magneto-optical disc, or a semiconductor memory is attached where appropriate. A computer program read from the removable medium  111  is installed in the storage unit  108  where appropriate. 
         [0125]    When the series of processes is to be executed by software, programs included in the software is installed in a computer incorporated in dedicated hardware or a general personal computer capable of executing various functions by installing various programs, for example, by a network or a recording medium. 
         [0126]    In this specification, a step of writing a program to be recorded in a recording medium apparently includes processes performed in a certain order in a time-series manner and also includes processes which are not executed in a time-series manner, that is, executed in parallel, or individually executed. 
         [0127]    Hereinabove, the liquid crystal display is used as the display unit  17  in which display thereof is controlled by the image display control apparatus according to the present disclosure. However, the present disclosure is applicable to not only the liquid crystal display but also the following display apparatus. Specifically, the present disclosure is applicable to a display apparatus which receives an instruction for display in a unit of a frame, a field, or the like which constitutes a moving image (hereinafter, such a unit is referred to as a comma). In such a display apparatus, a plurality of pixels included in a comma include display elements and some of the display elements are held for a predetermined period of time. Note that, such a display element is referred to as a hold display element hereinafter, and such a display apparatus including a screen including such hold display elements is referred to as a hold display apparatus. Specifically, the liquid crystal display apparatus is merely an example of the hold display apparatus, and the present disclosure is applicable to all hold display apparatuses. 
         [0128]    Furthermore, in addition to the hold display device, the present disclosure is applicable to a flat self-luminance display apparatus utilizing an organic EL (Electro Luminescent) device as a light-emitting device. Specifically, the present disclosure is applicable to all display apparatuses including display elements which display pixels constituting an image. Note that such a display apparatus is referred to as a pixel display apparatus. Here, in the pixel display apparatus, it is not necessarily the case that a single pixel corresponds to a single display element. 
         [0129]    In other words, any display apparatus in which display thereof is controlled by an image display control apparatus according to the present disclosure may be employed as long as the display apparatus is capable of executing the series of processes described above. 
         [0130]    Furthermore, in the foregoing embodiments, the case where the present disclosure is applied to the image pickup apparatus (such as a digital still camera) including the display apparatus (display unit) has been described. However, the image display control according to the present disclosure is applicable to other electronic apparatuses including display apparatuses such as a PDA (Personal Digital Assistants), a cellular phone, a portable game device, a portable reproducing apparatus, a television receiver, and the like. 
         [0131]    The embodiments of the present disclosure are not limited to the foregoing embodiments and various modifications may be made without departing from the scope of the present disclosure.
