Quick Capture camera interface

The Quick Capture camera interface is a component of Intel Quick Capture technology which provides a connection between the PXA270 processor and a camera image sensor. The Quick Capture interface is designed to work primarily with CMOS-type image sensors and supports up to 4 Megapixel resolution. However, it may be possible to connect some CCD-type image sensors to the PXA27x processor (PXA27x processor), depending on a specific CCD sensor’s interface requirements.

The Quick Capture interface acquires data and control signals from the image sensor, and performs the appropriate data formatting prior to routing the data to memory, using direct memory access (DMA). A broad range of interface and signalling options provides direct connection. The image sensor can provide raw data through a variety of parallel and serial formats. For sensors that provide pre-processing capabilities, the Quick Capture interface supports several formats for RGB and YCbCr colour space.

The Quick Capture interface signals are connected to the header J9. The I2C interface is available on the same header since most of the camera image sensors require an I2C control interface. For I2C bus address map on the ZEUS, see the section I²C bus on the previous page. For connector details, see the section J9 – Camera interface connector, page 82.
