Image output control system, image output device, and image processing device

Abstract

In the image output control system of the present invention, image processing is performed on image data by an image processing device, and the obtained data is supplied to the image output device to output an image. In the image processing device, for a pixel group in which a plurality of pixels constituting an image are summarized according to a predetermined number, the number of pixels formed in the pixel group is calculated, and the obtained number of pixels is calculated. The data is output to the image output device. In the image output device, a sequence of pixels in which dots are formed among pixels in a plurality of pixel groups is stored. Then, after receiving the data of the number of dots, one sequence is selected, and the pixel position in the pixel group is determined, a dot is formed at the pixel position, and an image is output. In this way, by supplying data on the number of pixels from the image processing device to the image output device, even an image with a large number of pixels can be quickly supplied with data, and thus the image can be output quickly.

Description

technical field [0001] The present invention relates to a technique for outputting images after performing predetermined image processing on image data. Specifically, it relates to rapidly transmitting image data after image processing to an image output device, thereby speeding up image output. Technology. Background technique [0002] Image output devices that represent images by forming dots on various output media such as printing media and liquid crystal screens are widely used as output devices for various image devices. In these image output devices, an image is subdivided into small areas called "pixels", on which dots are formed. When dots are formed on a pixel, there is no doubt that each pixel can only be in a certain state of forming a dot or not forming a dot. However, when viewed from the entire image, densely formed areas and sparsely formed areas of dots may occur. Thus, by changing the formation density of dots, an image can be output. For example, when ...

Problems solved by technology

[0005] However, after satisfying the high-quality and large-scale requirements of the output image, it is difficult to quickly output the image. That is to say, it is needless to say that the number of pixels is increased for the purpose of large-scale image. In order to improve the quality of the image, the number of pixels contained in one image is also increased by reducing the size of each pixel.

As mentioned above, since the image output device outputs the image after receiving the supplied data for controlling the formation of dots, when the number of pixels included in one image increases, the time required for supplying the data will increase. It becomes difficult to quickly output images
