Imaging serial interface ROM

Imaging serial interface ROM (ISIROM). An integrated circuit imaging device presents to external circuitry as a read-only memory (ROM) with a serial interface. The ISIROM contains internal memory which stores data from the imaging array. When active, the imaging array automatically fills an image buffer in the internal memory with image data. This image data may be accessed by external circuitry in random-access fashion. Control and status registers may be used to start and stop the imaging process, set and interrogate imaging parameters. The ISIROM may also include auxiliary processing circuitry to perform functions such as image compression, scaling, edge and feature extraction, and the like.
