Patent ID: 8514253

Claim:
An image data processing method for an image display system, comprising: providing the image display system with an image display device adapted to display an image based on image data, an information processing device adapted to transfer the image data to the image display device, and a transfer section intervening between the information processing device and the image display device; obtaining a transfer ratio from a ratio between an amount of data the image display device can display every unit time and an amount of data the transfer section can transfer every unit time; setting a plurality of pixel data extraction blocks, each of which includes a corresponding number of pixels to the transfer ratio, to the image data; comparing present frame data and previous frame data of consecutive frames in the image data; setting a pixel position of pixel data to be transferred at present moment in the present frame out of the pixel data of pixels included in each of the plurality of pixel data extraction blocks based on the result of the comparison in the comparing; transferring the pixel data to be transferred, from the information processing device to the image display device; setting a plurality of pixel data writing blocks corresponding to the plurality of pixel data extraction blocks in a display area of the image data; receiving the pixel data, which is transferred from the information processing device, by the image display device; setting a writing pixel position and a writing pixel count used when writing the pixel data, which is transferred in the transferring, into the pixel data writing block; and updating pixel data in the pixel data writing block by writing the pixel data into the pixel data writing block.
