The image data generation unit 4 appropriately adjusts the gain for each of the RGB color components with respect to the analog value signal of the image frame transferred from the electronic imaging unit 2, and then performs sample holding by a sample hold circuit (not shown). RAW image data is generated by converting into digital data by a D converter (not shown). Further, the image data generation unit 4 performs reduction processing of the RGB luminance information of the RAW image data at a predetermined magnification both horizontally and vertically to generate reduced resolution reduced luminance image data.
RAW image data and reduced luminance image data are DMA-transferred to an image memory 5 used as a buffer memory via a DMA controller (not shown).

The image memory 5 is composed of, for example, a DRAM or the like, and includes a first image selection unit 6, a change instruction detection unit 7, a display image specifying unit 8, a second image selection unit 9, a selection criterion control unit 10, Data and the like processed by the developing unit 13 and the central control unit 16 are temporarily stored.

The first image selection unit 6 is picked up from a plurality of image frames temporarily stored in the image memory 5 before a predetermined time from the operation timing (recording instruction timing) of the shutter key 15a of the operation input unit 15 by the user. Automatically select the selected image frame. More specifically, the first image selection unit 6 actually controls the shutter key 15a after a time lag set in advance, that is, when the user determines a photo opportunity, under the control of the selection reference control unit 10 (described later). Is determined based on the operation timing of the shutter key 15a from among a plurality of image frames temporarily stored in the image memory 5 on the basis of a time difference (for example, 0.2 seconds) from when the button is operated to when a recording instruction is output. One image frame captured before time (for example, 0.2 seconds) is selected.
Note that the first image selection unit 6 displays an image frame at a timing (recording instruction timing) when the shutter key 15a of the operation input unit 15 is operated by the user when the time lag is not set by the selection reference control unit 10. You may choose.
Here, the first image selection unit 6 selects, from a plurality of captured images acquired by the image memory 5, a captured image captured at a recording instructed timing or a predetermined time before the timing. It constitutes a selection means.

The change instruction detection unit 7 displays the image frame (captured image of the storage candidate) selected by the first image selection unit 6 on the display unit 12, and then selects the operation candidate unit 15 when the user selects the storage candidate image. The instruction signal output from the central control unit 16 based on the operation of the selection key 15c and the determination key 15d is detected as an instruction to change the image frame displayed on the display unit 12 as a storage candidate image.
Here, the change instruction detection unit 7 displays the captured image (captured image of the storage candidate) selected by the first image selection unit 6 and then displays the captured image displayed on the display unit 12 as the captured image of the storage candidate. Detecting means for detecting the change instruction.

  When the change instruction detection unit 7 detects a change instruction of the captured image, the display image specifying unit 8 is selected by the first image selection unit 6 as a captured image to be displayed under the control of the display control unit 11. A plurality of image frames captured at a plurality of timings before the timing at which the image frames are captured are specified.

The second image selection unit 9 includes a plurality of images captured at a plurality of timings before the imaging timing of the plurality of image frames specified by the display image specifying unit 8, that is, the image frames selected by the first image selection unit 6. A specific image frame (captured image) is selected from a plurality of displayed image frames by detecting a predetermined operation of the operation input unit 15 by the user while the image frame is displayed on the display unit 12. . Specifically, the second image selection unit 9 outputs from the central control unit 16 an instruction to select a specific image frame selected based on a predetermined operation of the selection key 15c or the determination key 15d of the operation input unit 15 by the user. If it is input, the specific image frame is selected as a captured image to be stored in the recording medium M based on the selection signal.

The selection criterion control unit 10 includes a timing acquisition unit 10a and a criterion correction unit 10b.
The timing acquisition unit 10a, as an imaging timing acquisition unit, captures a specific image frame (captured image) selected by the second image selection unit 9 by the imaging unit (lens unit 1, electronic imaging unit 2, and imaging control unit 3). The imaging timing at the time is acquired.

The reference correction unit 10b, as a selection reference correction unit, corrects the image frame selection criterion from among a plurality of image frames by the first image selection unit 6 based on the imaging timing acquired by the timing acquisition unit 10a. Specifically, since the imaging timing of the specific image frame acquired by the timing acquisition unit 10a is before a preset time lag (for example, 0.2 seconds), the reference correction unit 10b A time difference (for example, 0.3 seconds) between the image capturing timing of the frame and the operation timing (recording instruction timing) of the shutter key 15a is set as a new time lag.
Thereby, in the case of continuous shooting in the future, the first image selection unit 6 uses the shutter key 15a by the user from among a plurality of image frames on the basis of a newly set time lag (for example, 0.3 seconds). One image frame imaged before a predetermined time (for example, 0.3 seconds) from the operation timing is selected.

The display control unit 11 performs control to read out display image data temporarily stored in the image memory 5 and display the data on the display unit 12.
Specifically, the display control unit 11 includes a VRAM, a VRAM controller, a digital video encoder, and the like. The digital video encoder receives the luminance signal Y and the color difference signals Cb and Cr read from the image memory 5 and stored in the VRAM (not shown) under the control of the central control unit 16 via the VRAM controller. The data is periodically read from the VRAM, a video signal is generated based on these data, and is output to the display unit 12.

Further, the display control unit 11 converts the luminance signal Y and the color difference signals Cb and Cr (YUV data) generated by the developing unit 13 based on the luminance reduced image data of the image frame selected by the first image selection unit 6 into an image. Obtained from the memory 5, a video signal is generated based on these data and displayed on the display unit 12 as a storage candidate image.
Here, the display control unit 11 constitutes a first display control unit that causes the display unit 12 to display the captured image selected by the first image selection unit 6 as a captured image of a storage candidate.

In addition, after the change instruction detection unit 7 detects the change instruction of the storage candidate image, the display control unit 11 develops the development unit 13 based on the reduced-luminance image data of the plurality of image frames specified by the display image specifying unit 8. The luminance signal Y and the color difference signals Cb, Cr (YUV data) generated by the above are acquired from the image memory 5, and a video signal is generated based on these data and displayed on the display unit 12. That is, the display control unit 11 selects a plurality of image frames captured at a plurality of timings before the timing at which the image frame selected by the first image selection unit 6 is captured based on a predetermined operation of the operation input unit 15 by the user. Are displayed on the display unit 12 in a selectable manner.
Here, when the change instruction detection unit 7 detects the change instruction of the captured image, the display control unit 11 at least one captured image captured before the timing when the captured image selected by the first image selection unit 6 is captured. Is displayed on the display unit 12 in a selectable manner.

  The display unit 12 is, for example, a liquid crystal display device, and displays an image captured by the electronic imaging unit 2 on the display screen based on a video signal from the display control unit 11. Specifically, the display unit 12 displays a live view image based on a plurality of image frames generated by imaging the subject by the lens unit 1, the electronic imaging unit 2, and the imaging control unit 3, or records and saves an image. The REC view image is displayed.

  The developing unit 13 performs color process processing including pixel interpolation processing and γ correction processing on the RAW image data and the luminance reduced image data generated by the image data generation unit 4 using a color process circuit (not shown). The digital value luminance signal Y and the color difference signals Cb and Cr (YUV data) are generated.

The storage control unit 14 controls the writing of data to the recording medium M and the reading of data from the recording medium M under the control of the central control unit 16.
That is, the storage control unit 14 stores the image data for recording the image frame encoded by the JPEG compression unit (not shown) of the developing unit 13 in the recording medium (storage unit) M as a storage control unit. Specifically, when the change instruction detection unit 7 does not detect the change instruction of the stored image, the storage control unit 14 stores the image data of the image frame selected by the first image selection unit 6 in the recording medium M. On the other hand, when the change instruction detecting unit 7 detects the change instruction of the stored image, the image data of the image frame selected by the second image selecting unit 9 is stored in the recording medium M.
The recording medium M is composed of, for example, a non-volatile memory (flash memory) or the like. However, the recording medium M is an example and is not limited to this, and can be arbitrarily changed as appropriate.

  The operation input unit 15 is for performing a predetermined operation of the imaging apparatus 100. Specifically, the operation input unit 15 includes a shutter key 15a related to a subject shooting instruction, a mode key 15b related to an imaging mode selection instruction, a selection key 15c and a determination key 15d related to selection of various functions and display images, and the like. And a predetermined operation signal is output to the central control unit 16 in accordance with these key operations.

  The central control unit 16 controls each unit of the imaging device 100. Specifically, the central control unit 16 includes a CPU, a RAM, a ROM, and the like (all not shown), and performs various control operations according to various processing programs (not shown) for the imaging apparatus 100.

Next, image selection processing according to the image selection method performed by the imaging apparatus 100 will be described with reference to FIG. FIG. 2 is a flowchart illustrating an example of an operation related to the image selection process.
Here, the image selection process is executed when an image automatic selection mode is selected from a plurality of imaging modes displayed on the menu screen based on a predetermined operation of the mode key 15b of the operation input unit 15 by the user. Process.

As shown in FIG. 2, first, the central control unit 16 determines whether or not a continuous shooting recording instruction is input based on a predetermined operation of the shutter key 15a of the operation input unit 15 by the user (step S1).
If it is determined that the continuous shooting recording instruction is not input (step S1; NO), the central control unit 16 determines that the continuous shooting recording instruction is input (step S1; YES). The determination is repeatedly executed.
If it is determined in step S1 that a recording instruction for continuous shooting has been input (step S1; YES), the imaging control unit 3 determines the focus lens focus position and exposure conditions (shutter speed, aperture, amplification factor). Etc.) and white balance and other imaging conditions are adjusted, and an optical image of the subject is continuously captured by the electronic imaging unit 2 at a predetermined imaging frame rate (for example, 30 fps) for a predetermined number (for example, 20). (Step S2). Then, the image data generation unit 4 generates RAW image data and reduced luminance image data of each image frame of the subject transferred from the electronic imaging unit 2, and temporarily stores these image data in the image memory 5 (Step S1). S3).

  Next, the first image selection unit 6 selects a predetermined time (for example, 0.2 from the recording instruction timing (operation timing) of the shutter key 15 a by the user from among a plurality of image frames temporarily stored in the image memory 5. Second) automatically identifies the image frame (captured image) captured before (step S4). The display control unit 11 acquires the YUV data generated by the developing unit 13 from the image memory 5 based on the luminance reduced image data of the image frame (captured image) selected by the first image selection unit 6, and the video A signal is generated and displayed as a storage candidate image on the display unit 12 (step S5).

Subsequently, whether the change instruction detection unit 7 has detected an instruction to change the captured image displayed on the display unit 12 as a storage candidate image based on the operation of the selection key 15c or the determination key 15d of the operation input unit 15 by the user. It is determined whether or not (step S6).
Here, when it is determined that the change instruction is detected by the change instruction detection unit 7 (step S6; YES), the display image specifying unit 8 is before the imaging timing of the image frame selected by the first image selection unit 6. A plurality of image frames (captured images) captured at a plurality of timings are specified (step S7), and the display control unit 11 operates the operation input unit by the user with the plurality of image frames specified by the display image specifying unit 8. Based on the predetermined operation of 15, it is displayed on the display unit 12 so as to be selectable (step S8).

Next, the second image selection unit 9 selects a specific image from a plurality of image frames displayed on the display unit 12 based on a predetermined operation of the selection key 15c or the determination key 15d of the operation input unit 15 by the user. It is determined whether or not a frame (captured image) selection instruction has been detected (step S9).
If it is determined that a specific image frame selection instruction has not been detected (step S9; NO), the process proceeds to step S7, and the subsequent processes are executed.
When it is determined in step S9 that an instruction for selecting a specific image frame has been detected (step S9; YES), the second image selection unit 9 selects the selection key 15c or the determination key of the operation input unit 15 by the user. A specific image frame selected based on the predetermined operation 15d is selected (specified) as a captured image to be stored in the recording medium M (step S10).

Thereafter, the timing acquisition unit 10a of the selection reference control unit 10 acquires the imaging timing of the specific image frame (captured image) selected by the second image selection unit 9, and then the reference correction unit 10b sets the imaging timing. Based on the selection criterion of the image frame from the plurality of image frames by the first image selection unit 6, that is, the operation timing of the shutter key 15a from the imaging timing of the specific image frame selected by the second image selection unit 9. The time difference until (for example, 0.3 seconds) is corrected and set as a new time lag (step S11).
Here, whether or not the reference correction unit 10b corrects the selection criterion of the image frame from the plurality of image frames by the first image selection unit 6 can be selected based on a predetermined operation of the operation input unit 15 by the user. You may comprise.

  Thereafter, the central control unit 16 causes the development unit 13 to perform development processing of RAW image data relating to the specific image frame selected by the second image selection unit 9 and encoding processing in JPEG format, and the storage control unit 14. Stores image data for recording the specific image frame (captured image) in the recording medium M (step S12).

  On the other hand, when it is determined in step S6 that the change instruction is not detected by the change instruction detection unit 7 (step S6; NO), the process proceeds to step S12, and the subsequent processes are performed. That is, in step S12, the central control unit 16 causes the developing unit 13 to perform development processing of RAW image data related to the image frame selected by the first image selection unit 6 and encoding processing in JPEG format, and save the data. The control unit 14 stores the image data for recording the image frame in the recording medium M (step S12).

As described above, according to the imaging apparatus 100 of the present embodiment, an image frame as a storage candidate image captured before a predetermined time from the recording instruction timing is automatically selected from a plurality of image frames generated by continuous shooting. The specific image frame is selected by selecting a specific image frame captured before the capturing timing of the storage candidate image based on a predetermined operation of the operation input unit 15 by the user after being selected and displayed. Can be stored in the recording medium M.
That is, the time lag relating to the reflection time of the human or the full-press (stroke) operation of the shutter key 15a from when the user determines that the photo opportunity is taken until the user actually operates the shutter key 15a and outputs a recording instruction. There is a time lag related to time. However, in consideration of the time lag, a selection condition is set in advance so as to uniformly select one image frame captured before a predetermined time (for example, 0.2 seconds) from the operation timing of the shutter key 15a. Even in such a case, there is a possibility that an image captured at a timing different from the user-desired image is selected and stored.
Therefore, when an instruction to change the storage candidate image displayed on the display unit 12 is detected, a plurality of image frames captured before the image capturing timing of the storage candidate image are displayed on the display unit 12 in a selectable manner. A user-desired captured image (specific image frame) can be selected again based on a predetermined operation of the operation input unit 15. That is, when an image captured at a timing different from the user-desired image is selected instead of automatically selecting the captured image to be stored from the continuous captured image by the imaging apparatus 100. The captured image at the user-desired imaging timing can be selected based on a predetermined user operation from the outside, and the stored image stored in the recording medium M can be selected appropriately and simply.

In addition, after acquiring the imaging timing of a captured image (specific image frame) selected based on a predetermined operation by the user from the outside, a plurality of image frames by the first image selection unit 6 are acquired based on the imaging timing. Since the selection criterion for any one of the image frames from the inside is corrected, the time difference from the imaging timing of the specific image frame selected by the second image selection unit 9 to the operation timing of the shutter key 15a (for example, 0.3 Seconds) can be corrected and set as a new time lag. Thereby, in the case of continuous shooting in the future, the first image selection unit 6 uses the shutter key 15a by the user from among a plurality of image frames based on a newly set time lag (for example, 0.3 seconds). It is possible to automatically select one image frame imaged before a predetermined time (for example, 0.3 seconds) from the operation timing.
As described above, the imaging apparatus 100 can be made to learn to reflect the personality of the user to be used in the automatic selection of the captured image by the first image selection unit 6, and is automatically performed by the first image selection unit 6. After the picked-up image selected in the above is displayed on the display unit 12 as a picked-up image of a candidate for saving, if the instruction to change the picked-up image is not detected, the displayed picked-up image may be stored in the recording medium M. it can. Therefore, even when the image capturing apparatus 100 automatically selects a stored image from continuous shot images, the stored image can be selected appropriately and simply, and is more convenient to use. 100 can be provided.

The present invention is not limited to the above-described embodiment, and various improvements and design changes may be made without departing from the spirit of the present invention.
For example, the second image selection unit 9 captures a specific image frame (captured image) among a plurality of image frames captured at a plurality of timings before the imaging timing of the image frame selected by the first image selection unit 6. In addition to this, or in addition, for example, it is possible to select from a plurality of captured images captured at a timing after the imaging timing of the image frame selected by the first image selection unit 6 good.
That is, the display control unit 11 can select, as the second display control unit, at least one captured image captured at a timing after the imaging timing of the image frame selected by the first image selection unit 6 on the display unit 12. The second image selection unit 9 displays a specific captured image from at least one captured image displayed by detecting an external operation (such as the operation input unit 15) as a second selection unit. You may make it select.

  Furthermore, as described above, when a specific image frame is selected from a plurality of captured images captured at a timing after the imaging timing of the image frame selected by the first image selection unit 6, a timing acquisition unit Since the imaging timing related to the specific image frame acquired by 10a is after a preset time lag (for example, 0.2 seconds), the reference correction unit 10b detects the imaging timing of the specific image frame and the shutter key. A time difference (for example, 0.1 second) from the operation timing (recording instruction timing) 15a may be set as a new time lag.

The reference correction unit 10b does not necessarily need to set a time difference (actual time difference) between the imaging timing of a specific image frame and the operation timing of the shutter key 15a as a new time lag. Set a time difference (for example, 0.25 seconds or 0.15 seconds) as a new time lag so that (for example, 0.2 seconds) approaches the actual time difference (for example, 0.3 seconds or 0.1 seconds). May be.
Further, the reference correction unit 10b may acquire and set a new time lag from these average values after acquiring the actual time difference a predetermined number of times.

  In addition, the imaging apparatus 100 is provided with a user specifying unit that specifies a user to be used from at least one preset user, and a time lag controlled by the selection reference control unit 10 or a time lag by the reference correction unit 10b. Whether to correct or not may be set for each user in use.

  In addition, the configuration of the imaging apparatus 100 is merely an example illustrated in the above embodiment, and is not limited thereto. That is, the imaging apparatus 100 is illustrated as the image selection apparatus, but is not limited thereto. For example, an image selection apparatus that performs continuous shooting using an imaging apparatus different from the imaging apparatus 100, records only image data transferred from the imaging apparatus, and executes only an image selection process may be used.

In addition, in the above embodiment, the functions as an acquisition unit, a first selection unit, a first display control unit, a detection unit, a second display control unit, a second selection unit, and a storage control unit are provided. Under the control of the central control unit 16, the image memory 5, the first image selection unit 6, the display control unit 11, the change instruction detection unit 7, the display image specifying unit 8, the second image selection unit 9, and the storage control unit 14 are stored. However, the present invention is not limited to this, and may be realized by executing a predetermined program or the like by the CPU of the central control unit 16.
That is, in a program memory (not shown) that stores a program, an acquisition processing routine, a first selection processing routine, a first display control processing routine, a detection processing routine, a second display control processing routine, and a second selection processing are stored. A program including a routine and a storage control processing routine is stored. And you may make it the central control part 16 (acquisition means) acquire the some captured image produced | generated when the imaging part imaged a to-be-photographed object continuously by an acquisition process routine. In addition, the central control unit 16 (first selection unit) captures images from a plurality of captured images acquired by the acquisition unit by the first selection processing routine or at a timing instructed to be recorded or before a predetermined time from the timing. Alternatively, the captured image may be selected. The central control unit 16 (first display control unit) causes the display unit 12 to display the captured image selected by the first selection unit as a storage candidate captured image by the first display control processing routine. May be. In addition, after the display of the storage candidate captured image by the first display control unit on the central control unit 16 (detection unit) by the detection processing routine, the captured image displayed on the display unit 12 as the storage candidate captured image is displayed. A change instruction may be detected. In addition, when a change instruction is detected by the detection unit in the central control unit 16 (second display control unit) by the second display control processing routine, the timing before the timing when the captured image selected by the first selection unit is captured and You may make it display at least one picked-up image imaged at at least one timing after that on the display part 12 so that selection is possible. Further, from the at least one captured image displayed by the second display control means by detecting the operation from the operation input section 15 to the central control section 16 (second selection means) by the second selection processing routine. A specific captured image may be selected. Further, a specific captured image selected by the second selection unit may be stored in the recording medium M by the central control unit 16 (storage control unit) by a storage control processing routine.
