Step S2: A mode selection screen for image capture is displayed. FIG. 9 is a diagram showing a capture mode selection screen according to this embodiment. As shown in FIG. 9, a mode selection screen is displayed to determine in which mode the image is captured and displayed. There are three options: “image parameter setting”, “timing capture”, and “display area setting”. One of the modes on the mode selection screen is selected by the key input device 2b.

Step S3: "Image parameter setting" is selected from the mode selection screen by the key input device 2b. FIG. 8 is a view showing an image parameter setting screen according to this embodiment. This image parameter setting screen has five elements: [saturation], [brightness], [hue: red], [hue: green], and [hue: blue]. Decide whether to import as. For example,
When [brightness] is selected, it is determined that nine images in which the brightness is changed in nine levels, that is, images in which “dark → bright” is changed in certain steps, are displayed in order. At this time, PARA1M, PARA2M,... Which are [brightness] elements in the image parameter buffer (GAZO PARA BUFF).
... Values 1 to 9 are sequentially set in PARA9M.

Since “lightness 1 → 9” indicates “dark → bright”,
Therefore, the image 1 has the darkest setting and the image 9 has the brightest setting. Similarly, [Saturation] indicates the sharpness (clearness) of an image, and is represented by PARA1S to PARA9S.
And [hue] changes the redness, greenness, and bluish to large and small, respectively, and PARA1R to PARA9R and PAR, respectively.
A1G to PARA9G and PARA1B to PARA9B are set.

Step S4: "Display area setting" is selected from the mode selection screen by the key input device 2b. FIG. 10 is a diagram showing a display area setting screen according to the present embodiment.

Display / display for each image by the key input device 2b
The setting information for which non-display is set is stored in the display area management table (DISPNO) of FIG. 12, and display control is performed in step S10 based on this information.

Step S5: When "timing capture" is selected from the mode selection screen by the key input device 2b, the mode is automatically switched to the timing capture mode of the image. During this mode, images are captured by the video signal capture circuit 6 at predetermined time intervals, transmitted to the image processing unit 7, and sequentially stored in the RAM of the image processing unit in nine images.

Step S6: After the processing of steps S3 to S5 is performed, the control unit 1 sends a display start signal of the display image to the image processing unit 7, and upon receiving the signal, the image processing unit 7
Causes the video signal capture circuit 6 to start capturing a video signal. The display image is not a fetched video signal itself but a video signal thinned out to some extent. The video signal received at regular intervals is converted into a digital video signal for display by an image processing circuit each time, and written into the VRAM 4 by the control unit 1 and displayed by the display device 3. By performing this at regular intervals, a moving image is displayed.

Step S7: In displaying a moving image, an image to be actually captured is designated by a mouse or a keyboard of the key input device 2b. In response to this designation, the control section 1 requests the image processing section 7 for an actual video signal which is not thinned out. Then, the control unit 1 converts the image parameter setting information in step S3 and the timing capture setting information in step S5 into a request signal and transmits the request signal to the image processing unit 7. The image conversion request signal shown in FIG. 2 is prepared as the request signal. FIG. 2 is a diagram showing the contents of the image conversion request signal according to the present embodiment.

When "image parameter setting" is selected, the image parameter buffer 9 (GAZO PARA) is selected.
BUFF), the saturation value of PARA1S is the sai port signal, and the brightness value of PARA1M is mei po
The rt signal, the red value (hue) of PARA1R is the red port signal, the green value (hue) of PARA1G is the gre port signal, P
The blue value (hue) of the ARA1B is transmitted to the image processing unit 7 set in the blu port signal. This is performed for nine images.

When the image processing is started, an image capture mode request signal (mode port signal) indicating "image change mode" or "timing capture mode" shown in FIG. I do. "Image quality change mode" is "0",
“Timing capture mode” is set to “1”.

Step S8: Image Parameter Buffer 9
, And a buffer pointer (JBUFPT) provided in the image memory 5 are initialized. The buffer pointer indicates where the captured image is stored. FIG. 11 is a diagram showing one configuration of the RAM of the image memory according to the present embodiment. To set the first image in the image memory 5, 1 is set in the image number counter, and the buffer pointer (JBUFP
T) is set to 1 to control the capture and display of the incoming video signal.

Step S9: The digital video signal (image data) transmitted via the video signal capture circuit 6 and the image processing section 7 is stored in a buffer pointer (JBUF).
PT) in the area of the image memory 5 pointed to. At this time, in the case of the image quality change mode, the transmitted image has been subjected to image processing according to the image parameters set in step S7. For example, an image number counter (GAZ
When O NO) is 1, the image parameter PAR
A1S, PARA1M, PARA1R, PARA1G,
The image is set in PARA1B.

Step S10: It is determined whether to display the received image. Image number counter (GAZO
NO), the image number is identified, and the contents set in the display area management table (DISPNO) of FIG. 12 are referred to. If the received image is to be displayed based on the content, the process proceeds to step S13.

Step S11: The received image is compressed to a size that can be displayed. By performing the compression processing, nine images can be displayed as shown in FIG.
In the compression process, image data pointed to by the buffer pointer (JBUFPT) is transferred to the image compression unit 10 to be converted into compressed image data.

For example, if the size of the actually received image is 320 dots wide × 240 dots high, the display device 3 having a resolution of 640 dots wide × 240 dots high as shown in FIG. In order to display nine images, it is necessary to perform a compression process of 縦 times each in the vertical and horizontal directions so that the image has a size of 80 horizontal dots × 60 vertical dots.

Step S12: The image data compressed in step S11 is stored in an image number counter (GAZO
No.) is displayed at the display position managed. For example,
If the image number counter is 2, position information is obtained so as to be displayed at the position of the image 2 shown in FIG. 5, and the image data is stored in the address on the VRAM 4 corresponding to the position information.
Is converted by the image processing unit 7 into a recognizable format and stored. After the storage, the display is executed by the display device 3. Steps S9 to S12 are executed once for one image.

Step S13: In order to receive and display the next image, the image number counter (GAZO NO) is incremented, the buffer pointer (JBUFPT) is shifted by the size of one image, and the next image memory 5 is stored.
Set the address of

Step S14: It is determined whether or not the updated image number counter has exceeded nine. Step S9
It is determined whether or not the image is the ninth image for the number of images processed in S13. If there are still images to be processed, the process proceeds to step S9, and if completed, the process proceeds to step S15.

Step S15: The image number is input by the key input device 2b. Display of all nine images is completed, and the display of a plurality of images in FIG. 5 or FIG. 7 is completed. FIG. 7 shows a case where only the areas of the images 1, 5, and 9 are designated for display in the display area setting in step S4. In the display screen of FIG. 5, in the image quality change mode, image parameters in the order of 1 to 9 are image-processed with values of 1 to 9, and in the timing capture mode, 1 to 9
It is a new thing in the order of.

After the display, a screen is displayed for selecting an image to be actually captured and stored or to be edited / processed from the plurality of image types. Here, it is assumed that only one image can be selected, and the selection is performed by inputting numbers 1 to 9 using the key input device 2b. The input image number is sent to the image processing unit 7. In this way, many images whose image quality and timing have been delicately changed can be viewed at once, and this is an effective method for selecting an image suitable for the purpose.

Step S16: The entire image is displayed based on the input image number. The buffer pointer indicating the storage area of the image memory 5 is moved to the image position of that number. This image is not subjected to the compression processing performed for the list display in step S11, but is converted into image data to be displayed as it is, and only one image having the size shown in FIG. 6 is displayed.
For example, when image number 5 is input, only image 5 is enlarged and displayed on one sheet. This completes the capture of the video signal.

Step S17: If the above processing is in the image quality change mode, the image parameters of the designated image are taken out and stored in the image parameter buffer (GAZO P
(ARA BUFF) images 1 to 9 respectively. For example, in the process in which [Saturation] is fetched in nine steps, if image number 3 is selected in step S16, the image parameters of the image, PARA3S, P
ARA3M, PARA3R, PARA3G, PARA3
Extract the value of B.

Next, the value of PARA3S is changed from PARA1S to
In PARA9S, the value of PARA3M is set to PARA1M-P.
In ARA9M, the value of PARA3R is
Similarly, PARA3G and PARA3B are stored in RA9R. As a result, when the next capture is performed, one element of the selected image, here [saturation], is fixed to it, and the other elements can be changed and captured in nine levels. By repeating this operation, a wider variety of images can be viewed, and images suitable for the purpose can be effectively captured. In addition, the image quality change mode and the timing mode are also stored, and the recapture operation is performed in accordance with the mode.

The image quality adjustment and moving image capturing for a moving image have been described above. Hereinafter, an embodiment in which the image quality adjusting and the moving image capturing have an organic relationship will be described. FIG. 14 is a flowchart showing a subroutine of step S15 in FIG. In FIG. 14, step S15
In the state (time mode), one image is selected from the state in which the display of all nine images has been completed (see FIG. 15A).

Step S15-1: The display data (image data) on the VRAM 4 is saved. Step S15-2: 1 corresponding to the designated image number
The image is transferred to the 9-split screen of the VRAM 4 (1 in FIG.
9). The parameters shown in step S3 are set. Step S15-3: When the image capture mode request signal shown in FIG. 3 is set to “2” (VRAM data image quality change mode), nine pieces of image data in the VRAM are displayed according to the set parameters (FIG. 15). (B)). Here, the image number is input by the user.

Step S15-4: The parameters corresponding to the image of the designated number are set for all the images. Step S15-5: 9 saved in step S15-1
Returning the image data (display data) of the sheet to the VRAM 4;
It is displayed (see FIG. 15C). Here, the image number is input by the user. S15-6: Move to step S16 (FIG. 15D)

(A): A moving image whose timing is changed is captured. 9 time-series moving images are displayed. (B): One image (for example, the fifth image) is selected from the images, and the result of performing image quality adjustment of nine patterns on the one image is displayed. (C): When an image having a desired image quality (for example, No. 5 image quality) is selected from among these images, nine images are displayed in the selected image quality for all the moving images (A) at that image quality. A desired image (for example, the fourth image) is selected from these. (D): An image of the image quality selected by the user can be captured.

According to the image processing, it is possible to select from the number of screens according to the user's preference, and it is possible to provide more image quality adjustment methods. The operability of user parameter setting is improved. An image intended by the user can be captured. More images can be displayed, and images with desired image quality can be selected more quickly.
