Image processing apparatus and image display system

摘要

According to one embodiment, an image processing apparatus includes a receiver, a write controller, and a transmission controller. The receiver is configured to receive image data which forms an image to be displayed on a display apparatus. The write controller is configured to control to divide the image data into a plurality of regions and write compressed image data obtained by compressing the image data for each region, to a frame memory. The transmission controller is configured to control to transmit, to the display apparatus, original image data, which is restored by reading the compressed image data from the frame memory and decompressing the compressed image data for each region. Each of the regions has an overlap portion which is overlapped by a part of an adjacent region.

1. An image processing apparatus comprising:
a receiver configured to receive image data which forms an image to be displayed on a display apparatus; a write controller configured to control to divide the image data into a plurality of regions and write compressed image data obtained by compressing the image data for each region, to a frame memory; and a transmission controller configured to control to transmit, to the display apparatus, original image data, which is restored by reading the compressed image data from the frame memory and decompressing the compressed image data for each region, wherein each of the regions comprises an overlap portion which is overlapped by a part of an adjacent region, the overlap portion being used for compression and decompression of the image data at a boundary of adjacent two regions, and the transmission controller controls to transmit, to the display apparatus, a first region from which the image data of the overlap portion is removed, the first region being compressed later than a second region, the first region being adjacent to the second region, each of the first region and the second region being one of the plurality of regions.
