High performance and flexible imaging Sub-system

Imaging Sub-system (ISS) enables capturing photographs or live video from raw image sensors. This consists of a set of sensor interfaces and cascaded set of algorithms to improve image/video quality. This paper illustrates typical imaging sub-system architectures consisting of a Sensor front end, an Image Signal Processor (ISP) and an Image Co-processor (sIMCOP). Here we describe the ISS developed by Texas Instruments (TI) for the OMAP 5432 processor. The given solution is flexible to interface with various kinds of image sensors and provides hooks to tune visual quality for specific customers as well as end applications. This solution is also flexible by providing options to enable customized data flows based on actual algorithm needs. The overall solution runs at a high throughput of 1 pixel/clock cycle to enable full HD video at high visual quality.
