Abstract

PURPOSE:To improve the operability of an operator by processing the preparation of a fringed picture with exclusive OR and constituting image data to a pseudo stereoscopic body. CONSTITUTION:In order to prepare a fringed picture 26, a picture processor 4, microprogram 4a, and image controller 5 are actuated and two copies of an original picture 21 are taken. One copy 22 is parallel-displaced in the X-axis direction by one dot and the other copy 23 is similarly parallel-displaced in the Y-axis direction by one dot. Then exclusive OR are respectively taken by means of the controller 5 between the original picture 21 and displaced copies 22 and 23 so as to obtain the X-axis changing point picture 24 and Y-axis changing point picture 25 of the original picture 21. Then the controller 5 takes the exclusive OR of the picture 24 and 25 and prepares the data of a fringed picture 26. When the data are transferred to a picture memory 8 for display, the fringed picture 26 can be obtained. Therefore, a graphic can be constituted to a pseudo stereoscopic body quickly and easily and the operability of an operator can be improved.

However, no consideration has been given to pseudo-stereoscopic conversion of input two-dimensional image data.

[Problem to be solved by the invention]

Conventionally, the main function of a graphic processing program is processing such as drawing and editing graphics, but the only functions related to processing the two-dimensional image data itself include enlarging and reducing. Therefore, when performing pseudo three-dimensionalization of image data, even simple graphics require complicated operations by an operator.

As a result, the burden on the operator increases and the number of erroneous inputs increases, making graphic processing virtually impossible.

It is an object of the present invention to provide an image data processing method that can be easily executed and can greatly improve operability for an operator.

[Means for Solving the Problems] The above-mentioned object of the present invention is to provide an apparatus having a microprocessor, an image memory for storing data for display, and an output unit for outputting the contents of the image memory. The original figure A of the character figure inside and the horizontal direction (X
Create a figure B that has been moved a few dots in the vertical direction (direction) and a figure C that has been moved a few dots in the vertical direction (Y direction), and then create a figure that has been subjected to exclusive OR processing of the above figure B and the original figure A, and a figure that has been C
Image data characterized in that a white figure F of the above-mentioned character figure is obtained by performing a logical OR process with a figure E which is an exclusive OR process of the original figure A, and outputs this to the above-mentioned output section. Processing method, or in addition to the above processing steps, create a figure G by moving the original figure A in the diagonal directions of the X and Y axes, and create a logic between the figure G and the inverted figure of the original figure A. A projected figure H is created by performing product processing, and the projected figure H and the above-mentioned figure F are synthesized by logical sum processing to obtain a pseudo three-dimensional figure, which is output to the output section. This is achieved by the image data processing method according to claim 1.

[Effect]

In the image data processing method according to the present invention, the processing required when performing pseudo three-dimensionalization of image data includes:
Creation of a projection There are three elements: synthesis of a binary image and a projection, and creation of a border image to emphasize the contrast between the projection and the original image.

Creation of the projection is performed by logical product, synthesis of the one-dimensional image and projection is performed by logical sum, and creation of the border image is processed by exclusive logical sum. By controlling these processes, image data can be made into a pseudo three-dimensional image.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 2 is a block diagram of an image data processing system showing an embodiment of the present invention. In the figure, 1 is a microprocessor (CPU) for overall control.

An outline of the operation of the pseudo three-dimensional processing by the image data processing system shown in this embodiment is as follows.

In response to instructions from the microprocessor 1, image data is read from the display image memory 8 of the graphics processing device 7 and transferred to the video memory 6 in the image processing section 3 via the system bus 2. This data is transferred by the image controller 5 to the display image memory 8 after the pseudo three-dimensional processing is completed, and is displayed on the CRT 9.

FIG. 3 shows a memory map of the video memory 6.

The video memory 6 has an optical image storage area 10. X-axis scaled point image storage area 11 for creating a border image. Y-axis scaled point image storage area 12 for creating a border image. Border image creation area 13. Projection image creation area 14 and pseudo three-dimensional image storage area 15-6
It has two work areas and exchanges image data with the display image memory 8.

FIG. 1 shows a procedure for creating a pseudo three-dimensional image data using the image processing processor 4, microprogram 4a, and image controller 5 described above.

The above image processing processor 4 and microprogram 4
a. Start the image controller 5, and first copy the original image 21 on two sides in order to create the border image 26, and
The surface 22 is translated by one dot in the X-axis direction, and similarly, the other surface 23 is translated by one dot in the Y1111 direction. Next, the image controller 5 performs exclusive OR processing with the one-original image 21, respectively. As a result, an X-axis scaled point image 24 of the original image 21 and a Y-axis scaled point image 25 of the original image 21 are obtained. Next, the image controller 5 performs a logical OR process on these two images to create a border image 26. By transferring this data to the display image memory 8, a bordered image can be obtained.

In addition, in order to create a projected image 28, the original image 21 is translated by several dots in the diagonal directions of the X and Y axes and copied to obtain one image 27.Next, the image controller 5 is used to copy A logical AND process is performed between the image 27 and the inverted image of the original image 21.

As a result, a difference image 28 moved in the diagonal direction is created. This image 28 is just a projection of the original image 21. Finally, the image controller 5 performs a logical OR process on the border image 26 and the projection image 28 to transfer the two pieces of data for creating a pseudo-stereoscopic image 29 to the display image memory 8. You can get the image.

According to the above embodiment, in the graphic processing program, the image data itself is processed by the logical operation processing function, such as white outline display and pseudo three-dimensionalization of the two-dimensional image data, so complicated operations by the operator are not required. This method has the advantage that it is possible to easily display two-dimensional image data as a white outline, create a pseudo three-dimensional image, etc. By using this method, it is possible to easily display a figure or a heading character of a table in white or in pseudo three-dimensional form to make it easier to find.
