US 7843494 B2Abstract
a determining part that determines whether the image data has been captured by the image taking apparatus, and controls the correction control part to one of (i) continuously execute the image correction processes on the image data when it is determined that the image data has been captured by the image taking apparatus, and (ii) stop the image correction processes on the image data when it is determined that the image data has not been captured by the image taking apparatus. Description
As described above, at the time of capturing, a user determines the composition and timing and performs a shooting operation while viewing the image displayed on the display part 18 (color panel display 20). To ensure near real time display of an image signal from the image pickup device 13, image data restricted to the display size by the AFE part 14 is processed at a high speed by the image processing part 15, and is displayed on the display part 18 via the display control part 18 a. At the time of image playback, compressed data recorded in the recording medium 19 is read by the record/playback control part 19 a, played back by the image processing part 15, and displayed on the display part 18.
As mentioned above, the shutter control part 12 e controls the opening/closing of the shutter 12 b. The shutter control part 12 e performs exposure control to keep the amount of light input to the image pickup device 13 to a predetermined amount by performing such control as to close the shutter 12 b in a short time under a bright environment and close the shutter 12 b in a long time under a dark environment. At the time of exposure control, the shutter control part 12 e may perform control with the ND filter 12 a intervened between the lens part 12 and the image pickup device 13 in addition to switching the release time of the shutter 12 b. The flash part 16 is a fill light illuminating member which aids exposure. When the subject 90 is relatively or absolute dark, the flash part 16 which irradiates intensive light is used as a fill light. The flash part 16 is premised on a light source, such as white light LED or Xe discharge emission lamp, so that the amount of light can be controlled by the amount of current flowing.
The release button 21 activates the shutter 12 b via the shutter control part 12 e. The zoom button 22 adjusts the angle of view at the time of capturing.
The tag information 101 is unique information to the main image 102, where information, such as a shooting condition, on the main image 102 is stored. In the embodiment, stored in the tag information is information, such as camera-shake information 101 a, flash use information 101 b, AF position information 101 c, zoom position information 101 d, shutter speed 101 e, device model information 101 f and correction history information 101 g. The camera-shake information 101 a is information on the amount of shake, the shake direction, the time and the like of a camera shake detected at the time of capturing the main image 102.
After sequentially performing one correction process or a plurality of correction processes needed on the image data 100 based on information in the tag information 101 in this manner, the control program 500 instructs the image processing part 15 to compress the image data 100 according to the standards of JPEG or the like (step 411). Then, the control program 500 stores the compressed image data 100 in the recording medium 19 via the record/playback control part 19 a (step 412). At this time, the information in the tag information 101 before image correction is inherited directly, and information on the correction result of the electronic camera-shake correcting process A, the tone correcting process B, the red-eye detecting process C, or the red-eye correcting process D actually executed is stored in part of the tag information 101 as the correction history information 101 g. The transition of the screen of the color panel display 20 and the image data 100 in the one-touch correcting process 400 will be explained referring to FIGS. 6A, 6B, 7, 8 and 9. Note that the operations of displaying images or the like on the color panel display 20 in those diagrams are executed by the display control part 18 a based on an instruction from the control program 500.
In this case, it is shown that the main image 102 contains the camera-shake noise 102 a, the tone noise 102 b and the red-eye noise 102 c. In the present specification, the “tone noise 102 b” includes a word “noise” for the sake of convenience, does not means that specific noise data is mixed in the main image 102 but indicates that the main image 102 is in a state where tone (brightness, gradation) needs to be corrected.
In the example of FIGS. 6A and 6B, the main image 102 (display in the step 306) first displayed on a display screen 601 of the color panel display 20 contains the camera-shake noise 102 a, the tone noise 102 b and the red-eye noise 102 c. When a key operation associated with correction is executed from the state of the display screen 601, the control program 500 displays the frame-like one-touch correction wizard 201 over the main image 102 as exemplified in a display screen 602.
In the embodiment, next, the control program 500 instructs the display control part 18 a to separate the color panel display 20 to a left segment area 20 a and a right segment area 20 b. Then, the right segment area 20 b or the right half is filled in black. Next, based on the AF position information 101 c, the control program 500 zooms in the main image 102 toward the left segment area 20 a or the left half while sliding the main image 102 toward the left segment area 20 a in such a way that the autofocus portion of the main image 102 comes nearly the center of the left segment area 20 a. This state is shown as a display screen 604. Even during transition from the display screen 603 to the display screen 604, the progress indicator 202 is kept displayed, so that the user can observe the progress of the electronic camera-shake correcting process A.
Otherwise, the left half or the right half of the camera-shake corrected image 102 d, whichever has a larger change in the tone correcting process B, is displayed on the left segment area 20 a. When the red-eye correcting process D is executed at the time of displaying the display screen 608, the display screen 608 is displayed until the red-eye correcting process D is terminated.
As exemplified in a display screen 609, when the red-eye correcting process D is terminated during the display of the display screen 608, the all corrected image 102 g (red-eye corrected image 102 f) in which all of the camera-shake noise 102 a, the tone noise 102 b and the red-eye noise 102 c are corrected is faded into the right segment area 20 b. The display screen 609 is displayed until writing of the all corrected image 102 g into the recording medium 19 is completed (the steps 411 and 412 in FIG. 5), or for a predetermined time.
In this case, a display screen 631 shows the main image 102 which is displayed on the color panel display 20 in the step 306, and contains the tone noise 102 b and the red-eye noise 102 c, not the camera-shake noise 102 a. When a key operation associated with correction is executed from the state of the display screen 631, the control program 500 displays the frame-like one-touch correction wizard 201 over the main image 102 as exemplified in a display screen 632.
As exemplified in a display screen 635, after the red-eye correcting process D is terminated, the all corrected image 102 g (red-eye corrected image 102 f) in which all of the tone noise 102 b and the red-eye noise 102 c are corrected is faded into the right segment area 20 b. The display state of the display screen 635 is maintained only for the time for compressing an image (step 411) and of writing the image in the recording medium 19 (step 412) in the flowchart in FIG. 5 or only for a predetermined time.
The correction process combination 705 shows a case where the image data 100 is data captured by another device model different from the image taking apparatus 10, so that non of the correcting processes is executed. Whether the image data 100 is data captured by another device model can be known based on the device model information 101 f. The correction process combination table 700 is implemented as a part of the control program 500 as needed, and is used to control the one-touch correcting process 400.
