Image Generation

摘要

A method of generating an image comprises receiving a signal over a USB interface comprising encoded display data for one or more groups of pixels within an image, the encoded display data comprising display data for less than the whole of the image, and position data for the or each group of pixels. The encoded display data is decoded to generate pixel data for each group of pixels. A frame buffer, which may be part of the display, is then updated with the generated pixel data according to the position data ready for output to the display device.

1. A method of generating an image comprising:
maintaining, at a display control device, a frame buffer having display data for an entire image, the display data comprising pixel data for each pixel of the image; receiving a signal over a general purpose data connection at the display control device, the signal comprising encoded display data for one or more groups of pixels within the image, the encoded display data comprising display data for less than the whole of the image, and position data indicating a position of the one or more groups of pixels within the image, decoding the encoded display data to generate pixel data for the one or more groups of pixels, updating the frame buffer with the generated pixel data for the one or more groups of pixels according to the position data for the one or more groups of pixels, whereby the pixel data for the one or more groups of pixels provide a partial update of the image, and outputting at least a portion of the display data stored in the frame buffer to a display over a display-specific data standard connection.
