Abstract

PURPOSE:To expand the variation of an image output by providing a thinning processing part, synthesizing image data and thinning data and executing the thinning processing of a image data. CONSTITUTION:The image data composed of a two-dimensional arrangement are stored into an image data arranging part 1 and a desired numerical value is stored into a counter arranging part 4. A masking pattern in accordance with the numeric value stored in the arranging part 4 is set by a masking pattern developing processing part 5 and generated from a masking pattern generating part 3. The generated masking pattern is developed to a corresponding masking data arranging part 2 and stored as the thinning data. Next, a thinning processing part 6 synthesizes the image data of the arranging part 1 and the thinning data of the arranging part 2, the image data are thinned and the result is stored into a thinning processing completion data arranging part 7. Thus, the thinning processing of the image data can be executed by the setting of the arranging part 4, the partial variable density becomes free for the image data and the image variation can be extended.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to an image processing device used in various office automation equipment that handles image data.

(Prior Art) Various types of OA equipment have traditionally been equipped with a display screen that displays images, and by performing various processes on the image data displayed on this display screen, images can be rotated and enlarged. / Reduction and further shading adjustments are being made.

Incidentally, recently in this field, it has been desired to further expand the variation of image output by adding partial shading to the output image.

However, since the conventional shading adjustment is aimed at the entire image, there is a problem in that it is difficult to add the above-mentioned partial shading changes to the image.

(Problems to be Solved by the Invention) The present invention is intended to solve the above-mentioned problems with conventional image processing devices, and is capable of freely selecting and adding partial gradation changes to image data. The present invention aims to provide an image processing device that can further expand the variation of image output.

[Structure of the Invention] (Means for Solving the Problem) In order to achieve the above-mentioned object, the image processing device of the present invention includes an image data storage means for storing image data in a two-dimensional array, and this image data storage means. a thinned-out data storage means for storing thinned-out data having an arrangement substantially the same as that of the image data stored in the image data storage means; a setting means for setting a pattern of the thinned-out data to be stored in the thinned-out data storage means; The image data processing apparatus includes thinning processing means for synthesizing the stored image data and the thinning data stored in the thinning data storage means to perform thinning processing on the image data.

(Function) In the image processing device of the present invention, the thinned data set by the setting means is stored in the thinned data storage means, and then the thinned data stored in the thinned data storage means and the image data stored in the thinned data storage means are stored. Since the image data is combined with the image data stored in the device and the image data is thinned out, it is possible to freely select and perform partial shading adjustments to the image data, thereby further expanding the variation of image output. be able to.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

FIG. 1 is a diagram for explaining the configuration of an image processing device according to an embodiment of the present invention.

In the figure, 1 is an image data array section in which image data is stored in a two-dimensional array, 2 is a masking data array section in which masking data for thinning is stored, and this masking data array section 2 is an image data array section. It consists of the same array as 1.

Reference numeral 3 denotes a masking pattern generating section that generates a six-insert masking pattern that is a component of the masking data stored in the masking data array section 2.

As shown in FIG. 2, this masking pattern consists of, for example, a 2×2 signal array, and all possible combination patterns of this array are prepared. Each of these patterns is assigned a numerical value for identification.

Furthermore, 4 is a counter array section in which numerical values corresponding to each masking pattern are stored, and 5 is a counter array section in which a masking pattern corresponding to the numerical values stored in the counter array section 4 is generated from the masking pattern generation section 3 and is stored in the masking data array section 2. a masking pattern development processing section for development; 6 a thinning processing section for synthesizing the image data in the image data arrangement section 1 and the masking data in the masking data arrangement section 2 and thinning out the image data; 7;
is a thinned-out processing completed data array section that stores thinned-out image data.

Next, the operation of this embodiment device will be explained using FIG. 3.

First, some image data consisting of a 4×4 two-dimensional array is stored in the image data array section 1.

Here, desired numerical values (here, 1.0.3.2 from the upper left to the lower right) are stored in the counter array section 4.

As an operation for inputting numerical values into the counter array section 4, for example, there is a method of selecting from a masking pattern selection list displayed on the display screen using a mouse, a light pen, or the like.

Thereafter, the masking pattern development processing section 5 causes the masking pattern generation section 3 to generate masking patterns corresponding to each numerical value stored in the counter arrangement section 4, and develops these into the corresponding masking data arrangement section 2.

Thereafter, the thinning processing unit 6 uses the masking data developed in the masking data array unit 2 and the image data array unit 1.
The thinning processing is performed by combining the image data expanded into the image data by a predetermined method, and the result is stored in the thinning processing completed data array section 7.

That is, in the thinning process described above, for example, AN
When thinning processing is performed using the D gate, the output data appears visually darker as the data developed in the masking data array section 2 contains r IJ times as many signals.

Thus, according to the image processing device of this embodiment, the masking pattern to be developed in the masking data array section 2 is set in the counter array section 4, and the masking data and image data array developed in the masking data array section 2 are set. Since the image data can be thinned out by combining it with the image data developed in part 1, the operator can freely select and perform partial shading adjustment of the image data.

Note that in this embodiment, processing is performed using a masking pattern consisting of a 2 x 2 array in accordance with the image data consisting of a 4 x 4 two-dimensional array. Thinning processing may also be performed.

[Effects of the Invention] As explained above, according to the image processing device of the present invention, it is possible to freely select and perform partial shading adjustment on image data, thereby further expanding the variation of image output. Can be done.
