Image processing system

Claim 1

An image processing system, in which image data are displayed on a display screen within a display period, comprising: transformation means for transforming image data to form transmission image data defined by a plurality of color vectors, in which each color vector is composed of plural color vectors factors each comprising brightness and color difference data so that each color-vector factor manages a plurality of dots on the display screen; a memory for storing the transmission image data; encoder means for encoding the transmission image data transmitted from the memory to form video data to be displayed on the display screen within the display period; a clock generator for generating dot-clock signals each corresponding to each dot of the display screen; a start time generator for generating a normal start time relative to the beginning of the display period and at least one offset start time offset from the normal start time, the amount of offset being based on the number of the dot-clock signals; and transmission means responsive to the start time generator for transmitting each color vector of the transmission data stored in the memory to the encoder means, by which each color vector starts being transmitted with the normal start time when no horizontal scrolling will be carried out, and being transmitted with the offset start time when horizontal scrolling will be carried out.
