Abstract
A programmable display controller for use in a digital imaging system has a video control register, a data access controller and a programmable modulator. The programmable display control is designed to be used with a digital imaging systems, such as digital cameras, having a variety of display different devices that require respective different control signals, different image signal modulations, and so on. The video control register stores video mode bits indicating the type of video signal to output. The data access controller has a buffer for requesting image data and storing the requested image data in the buffer. The programmable modulator, in response to the video mode bits, generates a video signal from the image data stored in the buffer. In some embodiments, a decoder detects and decodes a link code in received image data. An address generator is responsive to the decoder and outputs a link address corresponding to the decoded link code for fetching image data that is stored at the link address.
