(First embodiment)
FIG. 1 is a block diagram showing a schematic electrical configuration of an electronic still camera 1 common to the embodiments of the present invention. The electronic still camera 1 is mainly configured by an MPU 4 having an image processing function such as converting image data obtained by a CCD 3 constituting an imaging unit together with a zoom lens 2 and the like into a JPEG format. An optical image of the subject that has passed through the zoom lens 2, the focus lens 5, and the diaphragm 6 is formed on the light receiving surface of the CCD 3.

  The zoom lens 2 is a lens group having a plurality of lenses and capable of changing the focal length (changing magnification) and correcting the optical characteristics, and is held by a drive mechanism 7 including a zoom motor or the like. Then, the MPU 4 outputs a control signal to the zoom driver 8 in accordance with the operation of the zoom key and the like, and the zoom driver 8 supplies the drive signal to the drive mechanism 7, whereby the zoom lens 2 is zoom-driven. The focus lens 5 is held by a drive mechanism 9 such as an AF motor, and the drive signal output from the AF driver 10 is supplied to the drive mechanism 9 by a control signal from the MPU 4 so that the focus lens 5 moves back and forth on the optical axis. Perform the focusing operation. The diaphragm 6 is driven by a drive signal generated by the diaphragm drive unit 11 based on a control signal from the MPU 4 and adjusts the light quantity of the subject image incident on the CCD 3.

  Further, a TG (Timing Generator) 12 that generates a timing signal is connected to the MPU 4, and a V driver 13 (vertical driver) drives the CCD 3 based on the timing signal generated by the TG 12. An analog imaging signal corresponding to the luminance of the image is output and sent to the unit circuit 14. The unit circuit 14 receives a CDS that holds an imaging signal output from the CCD 3, a gain adjustment amplifier (AGC) that is an analog amplifier to which the imaging signal is supplied from the CDS, and an imaging signal that is amplified and adjusted by the gain adjustment amplifier. It comprises an A / D converter (AD) that converts it into image data, and the output signal of the CCD 3 is sampled with the black level matched here and sent to the MPU 4 as a digital signal. The sent digital signal (imaging signal) is temporarily stored in the DRAM 15, and after being subjected to various image processing such as digital zoom processing, filter processing, white balance processing and the like by the MPU 4, the video is finally compressed. The signal is stored in a flash memory (FLASH) 16 as a signal. The stored video signal is read to the MPU 4 as necessary, and is generated into a digital video signal or an analog video signal through processing such as expansion processing, addition of a luminance signal and a color signal.

  Further, the MPU 4 includes operations including various keys and switches such as an MROM 17, a power supply circuit 18, the zoom key and shutter button, a mode setting key, and a selection key for selecting any through image displayed on the multi-screen described later. A key unit 19 and a TFT liquid crystal monitor 20 as display means are connected. The MROM 17 is a program ROM in which an operation program or the like of the MPU 4 shown in the flowchart described later is recorded. The MROM 17 also stores program AE data constituting a program diagram showing a combination of an aperture value (F) corresponding to an appropriate exposure value (EV) at the time of shooting and a shutter speed.

  The MPU 4 functions as display control means, selection means, recording control means, and the like of the present invention by operating in accordance with the operation program using the built-in RAM as a working memory. Further, according to the program diagram, the charge accumulation time of the CCD 3, the degree of opening of the diaphragm 6, the gain setting of the gain adjustment amplifier (AGC) of the unit circuit 14 and the like are performed. The charge accumulation time set by the MPU 4 is supplied as a shutter pulse to the V driver 13 via the TG 12, and the charge accumulation time, that is, the exposure time is controlled by the V driver 13 driving the CCD 3 according to this. That is, the CCD 3 functions as an electronic shutter. The operation program stored in the MROM 17 includes a program related to autofocus control. Based on the program, the MPU 4 drives the focus lens 5 to perform focusing (autofocus).

  The TFT liquid crystal monitor 20 displays images taken sequentially in a shooting mode as a through image or a multi-screen display, which will be described later, and displays an analog video signal generated from image data recorded in the flash memory 16 in a reproduction mode. Display video based.

  The program data and the like stored in the MROM 17 described above may be stored on another recording medium such as an IC card that is separately provided or detachably mounted as long as the recorded contents can be retained. The program data may be recorded, and the program data or the like may be supplied from another device such as a personal computer.

  Next, the operation of the electronic still camera 1 having the above configuration in the first embodiment will be described. In a state where the power switch is operated to turn on the power and the shooting mode is set by operating the mode setting key, the MPU 4 performs the procedure shown in the flowchart of FIG. 2 according to the program stored in the MROM 17. Execute the process. That is, the subject image formed on the CCD 3 is displayed on the full screen of the TFT liquid crystal monitor 20 as a through image (step S101). At this time, the lens (zoom lens) 2 is set at the standard position by the drive mechanism 7, and the digital zoom function of the MPU 4 is maintained in the off state. Therefore, the TFT liquid crystal monitor 20 has an angle of view with a standard magnification (optical zoom value of 1), and a subject image formed by the zoom lens 2 and not subjected to digital zoom processing is displayed as a through image. .

  Next, it is determined whether or not a multi-screen display mode is set by operating a mode setting key provided in the operation key unit 19 (step S102). If not set, the process proceeds to step S110 described later. . When the multi-screen display mode is set, digital zoom processing is performed on the image data of the subject from the unit circuit 14 so as to have different angles of view, as shown in FIG. In addition, a plurality of through images “1”, “2”, “3”, and “4” having different angles of view are displayed on the TFT liquid crystal monitor 20 in multiple screens (step S103).

  Subsequently, it is determined whether or not an angle of view change operation has been performed, that is, whether or not the zoom key has been operated (step S104). If the zoom key is not operated, it is further determined whether or not the shutter button is operated (step S105). Then, when the shutter button is operated without operating the zoom key (step S105; YES), the captured images with the angle of view currently set in the through images “1”, “2”, “3”, and “4” ( (Photographed image data) is generated and stored in the flash memory 16 (step S106).

  In generating the captured image data having a plurality of angles of view in step S106, either digital zoom or optical zoom may be used. That is, in the case of using the digital zoom, one shooting process is executed to obtain one subject image data from the unit circuit 14, and the through images “1” and “2” are obtained from the obtained subject image data. Image data of the angle of view currently set to “3” and “4” is generated, and each of these image data is stored and recorded in the flash memory 16. In the case of using the optical zoom, a control signal is output to the zoom driver 8 and the zoom lens 2 is driven by the drive mechanism 7, and the zoom value is converted into through images “1”, “2”, “3”, and “4”. The value is sequentially changed to a value corresponding to the currently set angle of view, and each time the zoom value is changed, one piece of subject image data is obtained from the unit circuit 14 and the image data is stored and recorded in the flash memory 16. .

  On the other hand, if the result of determination in step S104 is that a zoom operation has been performed, the view angles of the through images “1”, “2”, “3”, and “4” are slid by the amount corresponding to the zoom operation (step S107). That is, when the zoom-in operation is performed, the view angles of all the through images “1”, “2”, “3”, and “4” are enlarged and changed by the zoom-in operation, and when the zoom-out operation is performed, The angle of view of all the through images “1”, “2”, “3”, and “4” is reduced and changed by a zoom-out operation. Accordingly, the angle of view of each of the plurality of through images “1”, “2”, “3”, and “4” displayed on the multi-screen display on the TFT liquid crystal monitor 20 can be easily achieved by a simple operation of operating the zoom key in the multi-screen display state. In other words, a plurality of through images each having a different angle of view can be displayed on a multi-screen.

  Next, it is determined whether or not any of the through images “1”, “2”, “3” and “4” currently displayed on the TFT liquid crystal monitor 20 is selected by operating the selection key (step S108). The process from step S102 is repeated until it is selected.

  If any of the through images “1”, “2”, “3”, and “4” currently displayed on the TFT liquid crystal monitor 20 is selected (step S108; YES), the angle of view of the selected through image is displayed. The control signal is output to the zoom driver 8 until the zoom lens 8 is set, and the zoom lens 2 is set to the angle of view by the drive mechanism 7 and the subject image formed by the zoom lens 2 is displayed on the TFT liquid crystal monitor 20 alone on the full screen. It is displayed (step S109). Therefore, when the through image “2” is selected in FIG. 3A, the through image is displayed at the angle of view of the through image “2” as shown in FIG. The entire screen is displayed on the TFT liquid crystal monitor 20 alone.

  Further, it is determined whether or not the zoom key has been operated (step S110). If the zoom key has been operated, the zoom lens 2 is zoomed by the amount of the zoom operation in the same manner as described above (step S111). Therefore, in the present embodiment, a desired through image is selected from through images of different angles of view displayed on a multi-screen and displayed alone on the full screen, and then the angle of view of the through image is further finely adjusted. You can also

  In step S112 following step S110 or step S111, it is determined whether or not the shutter button has been operated. If the shutter button has been operated, a photographing process (step S113) and a recording process (step S114) are executed. To do. That is, the image pickup signal output from the CCD 3 is sent from the unit circuit 14 to the MPU 4 as a digital signal, and after necessary processing is performed by the MPU 4, it is finally stored in the flash memory 16 as a compressed video signal. The Rukoto.

  In the present embodiment, the process of step S109 is handled by optical zoom, the zoom lens 2 is set to the angle of view, and the subject image formed by the zoom lens 2 is displayed on the TFT liquid crystal monitor 20. Although the full screen display is performed independently, it may be supported only by digital zoom. That is, the selected through image may be enlarged and displayed on the entire screen of the TFT liquid crystal monitor 20. Alternatively, the digital zoom and the optical zoom may be used in combination, and an image with an angle of view that becomes the selected through image may be enlarged and displayed on the TFT liquid crystal monitor 20.

(Second Embodiment)
FIG. 4 shows the processing procedure of the MPU 4 in the second embodiment of the present invention. In a state where the power switch is operated and the power is turned on and the shooting mode is set by operating the mode setting key, the MPU 4 performs the procedure shown in the flowchart of FIG. 4 according to the program stored in the MROM 17. Execute the process. In other words, the subject image formed on the CCD 3 is displayed on the full screen as a through image on the TFT liquid crystal monitor 20 (step S201). At this time, a standard white balance of the MPU 4 is set as described below using white balance as image processing. Therefore, a subject image formed by the zoom lens 2 and having a standard white balance is displayed on the TFT liquid crystal monitor 20 as a through image.

  Next, it is determined whether or not a multi-screen display mode is set by operating a mode setting key provided in the operation key unit 19 (step S202). If not set, the process proceeds to step S210 to be described later. . When the multi-screen display mode is set, different white balance processing is performed on the subject image data from the unit circuit 14 to perform image processing (see FIG. 5A). Multiple through images with different white balances “1”, “2”, “3”, “4” (for example, through white images adjusted for auto white balance, sunlight, fluorescent lights, shades of trees, etc.) (Through image) is displayed on the TFT liquid crystal monitor 20 on a multi-screen (step S203).

  Subsequently, it is determined whether or not an image processing (white balance) change operation has been performed, that is, whether or not a white balance adjustment key provided in the operation key unit 19 has been operated (step S204). If the white balance adjustment key is not operated, it is further determined whether or not the shutter button has been operated (step S205). If the shutter button is operated without operating the white balance adjustment key (step S205; YES), the image processing currently set for the through images “1”, “2”, “3”, and “4” ( White balance) photographed images (photographed image data) are generated and stored in the flash memory 16 (step S206).

  When each piece of photographic image data having different white balance is generated in step S206, one photographic process is executed to obtain one piece of subject image data from the unit circuit 14, and one piece of obtained subject image data is obtained. The image data of the white balance currently set for the through images “1”, “2”, “3”, and “4” is generated from the image data, and these image data are stored and recorded in the flash memory 16. Of course, as in the first embodiment, the imaging process may be executed a plurality of times while sequentially changing the white balance value, and the obtained plurality of image data may be stored and recorded in the flash memory 16.

  On the other hand, if the image processing change operation is performed as a result of the determination in step S204, the image processing (white balance) of the through images “1”, “2”, “3”, and “4” is slid by the operation amount ( Step S207). Accordingly, the white of each of the plurality of through images “1”, “2”, “3”, and “4” displayed on the multi-screen on the TFT liquid crystal monitor 20 by a simple operation of operating the white balance adjustment key in the multi-screen display state. By simply changing the balance, a plurality of through images each having a different white balance from the conventional one can be displayed on a multi-screen.

  Next, it is determined whether or not any of the through images “1”, “2”, “3”, and “4” currently displayed on the TFT liquid crystal monitor 20 is selected by operating the selection key (step S208). The process from step S202 is repeated until it is selected.

  If any one of the through images “1”, “2”, “3”, and “4” currently displayed on the TFT liquid crystal monitor 20 is selected (step S208; YES), the through image including the selected white balance is selected. The image is displayed on the TFT liquid crystal monitor 20 alone on the full screen (step S209). Therefore, when the through image “2” is selected in FIG. 5A, the through image composed of the white balance of the through image “2” as shown in FIG. 5B by the processing in step S209. Is displayed on the TFT liquid crystal monitor 20 alone on the full screen.

  Further, it is determined whether or not the white balance adjustment key has been operated (step S210), and if it has been operated, the image processing is changed by the amount of operation, and the entire screen is displayed alone on the TFT liquid crystal monitor 20. The white balance of the through image “2” is changed (step S211). Therefore, in the present embodiment, a desired through image is selected from through images of different white balances displayed on a multi-screen and displayed alone on a full screen, and then the white balance of the through image is further finely adjusted. You can also

  In step S212 following step S210 or step S211, it is determined whether or not the shutter button has been operated. If the shutter button has been operated, a photographing process (step S213) and a recording process (step S214) are executed. To do. In other words, the image pickup signal output from the CCD 3 is sent as a digital signal from the unit circuit 14 to the MPU 4, and is subjected to the same white balance processing as the white balance of the through image “2” displayed alone on the full screen. After that, it is finally stored in the flash memory 16 as a compressed video signal.

  In the present embodiment, the white balance has been described as the image processing. However, the present invention is not limited to this and can be applied to other image processing such as filter processing. For example, blue and red. It is conceivable to display through images with filters such as black and white and sepia displayed on multiple screens, or display through images with different brightness, color enhancement level, skin color correction level, and edge enhancement level on multiple screens.

  Further, in the present embodiment, as a result of the determination in step S204 of FIG. 4, when the image processing change operation is performed, the white balance values (adjustment amounts) of the plurality of through images displayed on the multi-screen are slid and changed. However, when there is an image processing change operation (or an operation for selecting a desired type of image processing), the processing is switched to another type of image processing (for example, filter processing) other than the white balance processing. A plurality of through images having different image adjustment amounts in different types of image processing may be displayed on a multi-screen. Furthermore, the slide change operation for changing the adjustment amount of the image processing (for example, white balance) for the plurality of through images displayed on the multi-screen and the image processing for the plurality of through-images displayed on the multi-screen are different. Both the image processing change operation for switching to the type of image processing may be validated.

  In the present embodiment, a plurality of through images having different image adjustment amounts are displayed on a multi-screen in one type of image processing. However, a plurality of through images subjected to different types of image processing are displayed on a multi-screen. You may make it display on a screen. For example, in addition to displaying a plurality of through images with different degrees of red filter (color density) on a multi-screen display, a through image with a red filter, a through image with a blue filter, or the like may be displayed on a multi-screen. It is done.

  In the first and second embodiments, when shooting is instructed while a plurality of through images are displayed on a multi-screen, a plurality of shot image data corresponding to each through image is generated. However, after shooting, a plurality of generated shot image data may be displayed on a multi-screen, and only the shot image data selected by the user may be recorded.

  In the first and second embodiments, the case where the present invention is applied to an electronic still camera has been described. However, the present invention is not limited to this, and other camera-equipped mobile phones. The present invention can be easily applied to terminals, PDAs with cameras (Personal Digital Assistants), personal computers with cameras, and the like.
