Dual image sensor stereo camera reference design

January 06, 2012 // By Julien Happich
Lattice Semiconductor and Aptina have jointly developed a low cost, dual image sensor design using two Aptina MT9M024/MT9M034, 720P image sensors. The images are combined into a single bus on which an ISP (Image Signal Processor) can operate. The output stream can be used to implement 3D stereoscopic video or for other multi-camera applications.

The low cost of the solution enables other consumer applications such as automotive black box drive recorders and surround view cameras. The low cost, low power Lattice MachXO2 PLD and a small SDRAM chip implement the necessary logic and frame buffering that allow the two image sensors to be merged into one ISP bus. The dual image sensor design allows ISP vendors to quickly offer multiple camera solutions for the consumer market. Because the MachXO2 device is programmable, many other dual camera implementations are also possible.
