In this sense, the input image storage device 100, the frame memory 200, and the processor 300 constitute the image data acquisition means.

The processor 300 is connected to the user interface unit 400 and the frame memory 500, can exchange data with the user interface unit 400, and can output data to the frame memory 500. Here, the user interface unit 400
Has an output medium such as a display (not shown) and an input medium such as a keyboard (not shown), and displays the pseudo moving image generation reference parameters such as edge direction, edge intensity, brightness, saturation, hue, and randomness on the output medium. It is possible for the user to select the pseudo moving image generation reference parameter using this input medium, and to input the number of frames of the pseudo moving image and the display order of the representative values in the generated moving image.

The pseudo moving image generation reference parameters, the number of frames of the pseudo image, and the display order of the representative values in the generated moving image selected by the user are output to the processor 300. It is possible to apply an edge detection filter and to convert its color space, and each pixel is based on a pseudo moving image generation reference parameter specified by the user through the user interface unit 400. Edge detection filters are applied or converted to color space. Each pixel subjected to this filter application or color conversion is output to the frame memory 500 for each belonging range in accordance with the display order of the representative values specified by the user interface unit 400.

The frame memory 500 holds input image data and outputs the image data.
The pixels input to the frame memory 500 by the processor 300 are converted into image data of one frame for each belonging range, and are output to the output image storage device 600. The output image data is acquired and held by the output image storage device 600 in the order specified by the user interface unit 400,
This is used as moving image data. In this sense, the processor 30
0, user interface unit 400, and frame memory 5
00 and the output image storage device 600 constitute the pseudo moving image generation device.

FIGS. 2 to 5 show flowcharts of control of the processor 300 in the present embodiment. First, an original image for generating a moving image is acquired from the input image storage device in the frame memory 200 (step S100). Next, the number of frames corresponding to the number of frames of the pseudo moving image (hereinafter referred to as f
), And obtains the pseudo moving image generation reference parameter and a display order indicating whether to display the representative value of the pseudo moving image generation reference parameter in descending order or in the ascending order (step S110). ). Then, the pseudo moving image generation parameters acquired in step S110 are determined (step S120), and control according to each pseudo moving image generation reference parameter is performed.

FIG. 3 is a flowchart when the edge direction is selected as the pseudo moving image generation reference parameter. First, the number (hereinafter, referred to as d) of dividing the edge direction from the display order acquired in step S110 is acquired (step S200). Here, the number of divided edge directions means the number of designated directions when designating which edge direction is displayed in which order. For example, the display order is the vertical direction, the horizontal direction, If it is in an oblique direction, the number of divisions is three. Next, the number of frames f obtained in step S110 is divided by the number of divisions d in the direction to obtain the number of frames in each direction (hereinafter referred to as e) (step S210). Then, a Sobel filter is applied to each pixel of the image data acquired in step S100 (step S220) to determine an edge gradient of each pixel, and among the edge gradients, a maximum value in each direction of the edge direction is determined for each direction. By dividing by the number of frames e, a change value (hereinafter referred to as n) of an edge gradient in one frame in each direction is obtained (step S230).

Once this change value n is obtained, step S11 is performed.
For the direction initially displayed as 0, pixels whose gradient values are included in the belonging range “(e−1) × n to e × n” of one frame are obtained and output to the frame memory 500 (step S240). . In step S240, the pixels in the belonging range are obtained one by one, and it is determined whether or not all the pixels in the range are obtained (step S250). If all the pixels in the range are not obtained, the process returns to step S240. This processing is repeated, and if all of the pixels in the range have been acquired, the image data stored in the frame memory 500 is output to the output image storage device 600 (step S).
260). Thereafter, “e = e−1” is set (step S270), and it is determined whether or not “e <1” is satisfied (step S280). If it is determined that “e <1” is not satisfied, step S240 is performed. And the above processing is repeated. That is, the above process is repeated by the number of frames in the direction.

If it is determined in step S280 that "e <1", it is determined whether or not the above processing has been performed for all the directions specified in step S110 (step S290). Is determined not to have been performed, an edge direction to be displayed next to the edge direction of the image from which the image data has been obtained is obtained (step S295), and the process returns to step S240 to perform the above-described processing for this obtained direction. Do. If it is determined in step S290 that the above processing has been performed for all directions, the display order specified in step S110 is obtained, and the output image storage device 600
Then, an image sequence of the moving image is generated by creating an output image sequence such that the image data stored in the image data is in the display order (step S296), and the image generation processing is ended.

FIG. 4 shows a flowchart when brightness is selected as a pseudo moving image generation reference parameter. In this case, color space conversion is performed for each pixel of the image data acquired in step S100 (step S30).
0), converting from the RGB color space to a color space such as HSI, HSV, HSL, etc. Next, the maximum value of the brightness of the pixel data obtained as a result is divided by the number of frames f obtained in step S110 to obtain a change in brightness (hereinafter referred to as n) in one frame (step S310).

When the change value n is obtained, the pixels whose lightness values are included in the belonging range "(f-1) × n to f × n" of one frame are obtained and output to the frame memory 500 (step S320). . Then, in step S320, the pixels in the belonging range are obtained one by one, and it is determined whether or not all the pixels in the range are obtained (step S330). If not all the pixels in the range are obtained, step S3 is performed.
20, the process is repeated, and if all of the range pixels have been acquired, the image data stored in the frame memory 500 is output to the output image storage device 600 (step S340). Thereafter, “f = f−1” is set (step S350), it is determined whether or not “f <1” is satisfied (step S360). If it is determined that “f <1” is not satisfied, step S320 is performed. And the above processing is repeated. That is, the above processing is repeated by the number of frames.

If it is determined in step S320 that "f <1", the display order specified in step S110 is obtained, and the image data stored in the output image storage device 600 is displayed in this display order. The image data of the moving image is generated by creating an output image sequence as follows (step S370), and the image generation processing ends.

Here, FIG. 4 shows a flowchart when brightness is selected as the pseudo moving image generation reference parameter. However, even when edge strength, saturation, and hue are selected as the pseudo moving image generation reference parameters, the above control is performed. It is almost the same as FIG. That is, in FIG. 4, the maximum value of the lightness is divided by the number f of frames acquired in the step S110 in the step S310, but the edge strength or the saturation may be removed here. However, when the pseudo moving image generation reference parameter is hue, the hue value is generally 0.
It has a value from degrees to 360 degrees, and since 0 degree and 360 degrees have the same hue and the hue circulates, the result of dividing 360 by the number of frames f is set as the hue change value in one frame.

FIG. 5 shows a flowchart when random is selected as the pseudo moving image generation reference parameter. First, the total number of pixels is divided by the number f of frames acquired in step S110 to determine the number of display pixels in one frame (hereinafter, referred to as n) (step S400). Next, n is substituted for a variable N (step S410), and pixels are randomly acquired and output to the frame memory 500 (step S420). Then, "N = N-1" is set (step S430), and it is determined whether or not "N <1" (step S440). If not "N <1", the process returns to step S420 to repeat the above processing. . That is, it is determined whether the number of pixels required for one frame has been acquired using the variable N.

When the number of pixels required for one frame has been obtained by the above processing, the image data stored in the frame memory 500 is output to the output image storage device 600 (step S450). Thereafter, “f = f−1” is set (step S460), it is determined whether or not “f <1” is satisfied (step S470). If it is determined that “f <1” is not satisfied, step S410 is performed. And the above processing is repeated. That is, the above processing is repeated by the number of frames. If it is determined in step S410 that “f <1”, the image generation processing ends. In this case, the image data output to the output image storage device 600 is the output image sequence regardless of the display order unlike the other pseudo moving image generation reference parameters.

Next, the operation of this embodiment having the above configuration will be described. First, the user holds an original image for generating a moving image as shown in FIG. 6 in the input image storage device 100. When the user activates the pseudo-moving image generation apparatus of the present embodiment, the processor 300 stores the image of FIG. 6 in the frame memory 200 as image data, and the user operates the user interface unit 400 to determine the number of frames and the pseudo-moving image generation standard. After entering the parameters and display order,
The processor 300 performs the control shown in the flowcharts of FIGS. 2 to 5 and acquires a brightness value or the like for each pixel as a pseudo moving image generation reference parameter value for each pixel.

By obtaining this pseudo moving image generation reference parameter value and dividing by the above-mentioned number of frames, the range to which the pseudo moving image generation reference parameter value of the pixel to be obtained for each frame belongs is determined. Image data is generated and stored in the output image storage device 600. When the next image is displayed so as to be superimposed on the previous image in the order specified in the display order, the pixels belonging to the respective belonging ranges are gradually displayed to complete the original image. Data is generated.

When a random moving image, an edge direction, or an edge strength is selected as a pseudo moving image generation reference parameter, these pseudo moving image generation reference parameters are calculated from the luminance components of the original image. It can also be applied to monochrome images. When lightness, saturation, or hue is selected as the pseudo moving image generation reference parameter, these pseudo moving image generation reference parameters are calculated from the RGB components of each pixel of the original image, and thus can be applied only to a color image.

Here, the state of the acquired image data when each pseudo moving image generation reference parameter is selected will be described. FIG. 7 shows an image when a random number is set as the pseudo moving image generation reference parameter and the number of frames is about 8 to 10. By displaying such an image gradually, the original image is gradually gradually reduced. Image data of a moving image in which an image is completed is generated.

FIG. 8 shows an image when the edge direction is set as the pseudo moving image generation reference parameter and the number of frames is about 8 to 10. By displaying such an image gradually, the edge is displayed. Moving image data is generated in which the original image is gradually completed for each direction in which the direction changes. That is, since the edge direction indicates a relative relationship with surrounding pixels by a gradient, when image data of a moving image is acquired so as to be displayed in accordance with the directionality of the edge, the moving image has, for example, a vertical edge direction, Pixels in an oblique direction and a horizontal direction are sequentially displayed.

FIG. 9 shows an image when the edge strength is used as a pseudo moving image generation reference parameter and the number of frames is about 8 to 10. By displaying such an image gradually, the edge is displayed. Moving image data is generated in which the intensity gradually changes and the original image is completed. That is, since the edge strength indicates a relative relationship with surrounding pixels, when image data of a moving image that completes the original image is generated by displaying pixels in order from the representative value of the edge intensity, the moving image Is displayed from a flat part with little image change, and if image data of a moving image that completes the original image is displayed in order from the pixel with the representative value of edge strength being large, the moving image Will be displayed starting from the contour part with the largest number.

FIG. 10 shows an image when the hue is taken as the pseudo moving image generation reference parameter and the number of frames is about 8 to 10. By displaying such an image gradually, the hue is changed. Image data of a moving image that gradually changes to complete the original image is generated. That is, as described above, generally, the hue value changes from 0 degree to 360 degrees, returns to the hue of 0 degree at 360 degrees, and gradually becomes red, yellow, green, and the like from 0 degree to 360 degrees. Light blue, blue,
Changes to purple and red. Therefore, when the image data of a moving image that completes the original image is generated by displaying the representative values of the hue in order from the smallest pixel, the moving image includes pixels of red, yellow, green, light blue, blue, purple, and red shades. It will be displayed in order. Also, when the image data of a moving image that completes the original image is generated by displaying the representative values of the hue in order from the pixel having the largest value, the moving image includes pixels of red, purple, blue, light blue, green, yellow, and red shades. It will be displayed in order.

FIG. 11 shows an image when the saturation is taken as the pseudo moving image generation reference parameter and the number of frames is about 8 to 10. By displaying such an image gradually, the saturation is increased. Moving image data is generated in which the degree gradually changes and the original image is completed. That is, since the saturation represents the vividness of the color, if the representative image of the saturation is displayed in order from the pixel having the smallest value and the image data of the moving image that completes the original image is generated, the moving image starts from the thin pixel. This gradually displays dark pixels. Also, when image data of a moving image that completes the original image is generated by displaying pixels in order from the representative value of the saturation value, the moving image gradually displays lighter pixels from darker pixels.

FIG. 12 shows an image when the brightness is taken as a pseudo moving image generation reference parameter and the number of frames is about 8 to 10. By displaying such an image gradually, the brightness is increased. Image data of a moving image that gradually changes to complete the original image is generated. That is, since the lightness represents the lightness and darkness of the color, the representative value of the lightness is displayed in order from the pixel having the smallest value, and when the image data of the moving image that completes the original image is generated, the moving image gradually starts from the dark pixel. Bright pixels are displayed. In addition, when pixels are displayed in order from the pixel having the largest brightness representative value and image data of a moving image that completes the original image is generated, the moving image gradually displays dark pixels from bright pixels.

Further, as described above, a method of generating a pseudo moving image based on the pseudo moving image generation reference parameter can be in various modes. As one example, for example, for a pixel included in the range of the parameter selected as the pseudo moving image generation standard, the edge direction θ at the position of the pixel is obtained, and a small area such as a rectangle or an ellipse is written. By such a method, a pseudo moving image having an illustration-like atmosphere is generated. Images at this time are shown in FIGS.
13 shows the pseudo moving image generation reference parameters, FIG. 14 shows the edge direction, FIG. 15 shows the edge strength, FIG. 16 shows the hue, FIG. 17 shows the saturation, and FIG. 18 shows the brightness.

The pseudo moving picture generating apparatus can be incorporated in digital equipment, and an embodiment thereof is shown in FIG. In FIG. 19, the CCD imaging device 110 can acquire an image as digital data, and generates still image data of a captured image. The CCD image sensor 110 is connected to a frame memory 210, and can output the generated still image data to the frame memory 210. Further, the frame memory 210
Is connected to the processor 310 and converts the input data to 1
The image data can be held as still image data for a frame and can be output to the processor 310.

The processor 310 is connected to a user interface unit 410 and a merge processing unit 510, can exchange data with the user interface unit 410, and can output data to the merge processing unit 510. Here, the user interface unit 410
Has an output medium such as a liquid crystal display (not shown) and an input medium such as a push button (not shown). The output medium has pseudo moving image generation reference parameters such as edge direction, edge intensity, brightness, saturation, hue, and random. Can be displayed, and the user can select the pseudo moving image generation reference parameter by using this input medium and input the number of frames of the pseudo moving image and the display order of the representative values in the generated moving image.

The pseudo moving image generation reference parameters selected by the user, the number of frames of the pseudo image, and the display order of the representative values in the generated moving image are output to the processor 310.
The processor 310 can apply an edge detection filter to each pixel of the input image data, and can convert the color space thereof. An edge detection filter is applied or converted to a color space based on a pseudo moving image generation reference parameter specified by the user. Each pixel that has been subjected to this filter application or color conversion is generated as one piece of image data for each range to which the representative value belongs instructed by the user interface unit 410, and the generated image data is merged with the merge processing unit 51.
Output to 0.

The input image data is merged into one image by the merge processing unit 510 and can be output to the output image storage device 610.
The image data merged into the merge processing unit 510 by the processor 310 is stored in the output image storage device 610. Here, the output image storage device 610
Is a recording medium such as a floppy disk or a flash card.

In the embodiment shown in FIG. 1, the pseudo moving image is a sequence of a plurality of output frames. However, in the embodiment shown in FIG. 19, each output frame is considered as one image, and these are regarded as one image file. The data is recorded by merging with. That is, the CCD image sensor 1
The image captured in step 10 is stored in the frame memory 210 as image data, and the processor 310 generates pseudo moving image frames “# 1 to #n” based on information selected by the user through the user interface 410, and the merge processing unit 5
10 merges these pseudo moving image frames into one file and outputs it to the output image storage device 610. As a result, a pseudo moving image file can be generated by a digital camera or the like using a CCD image sensor.

As described above, in the present invention, the pseudo moving image generation reference parameter value is obtained from the still image data, and the range to which the representative value of the pseudo moving image generation reference parameter belongs is determined.
The image data of the moving image in which the original image is completed is generated by gradually displaying the pixels belonging to each belonging range. Therefore, a pseudo moving image can be easily generated from one still image without performing a complicated operation of preparing images that change little by little one by one.

[0049]

As described above, according to the present invention, since a pseudo moving image can be generated from one still image, a highly versatile pseudo moving image generating apparatus capable of easily generating a pseudo moving image can be provided. According to the second aspect of the present invention,
Since the brightness can be gradually changed, a pseudo moving image having a moving image visual effect can be easily generated. Further, according to the third aspect of the present invention, since the saturation can be gradually changed, a pseudo moving image having a moving image visual effect can be easily generated.
