Quick Capture camera interface

The Quick Capture interface is a component of Intel
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 resolutions up to 4 mega pixels. However, it may be possible to connect
some CCD-type image sensors to the PXA27x processor, depending on the 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 J2. An I
available on the same header since most of the camera image sensors require an I
control interface. For connector details see the section
page 67.
