Pcam 5C Reference Manual

The Pcam 5C is an imaging module meant for use with FPGA development boards. The module is
designed around the Omnivision OV5640 5 megapixel (MP) color image sensor. This sensor
includes various internal processing functions that can improve image quality, including automatic
white balance, automatic black level calibration, and controls for adjusting saturation, hue, gamma
and sharpness. Data is transferred over a dual-lane MIPI CSI-2 interface, which provides enough
data bandwidth to support common video streaming formats such as 1080p (at 30 frames per
second) and 720p (at 60 frames per second). The module is connected to the FPGA development
board via a 15-pin flat-flexible cable (FFC) that is pin compatible with the connector found on the
popular Raspberry Pi development board. The Pcam 5C comes with a 10 cm flat-flexible cable and a
factory-installed fixed focus lens with M12 lens mount, so it is ready to use out of the box.

FPGA host there are two realistic options 1 Pay a license fee to acquire MIPI CSI 2 IP that is designed to work in FPGAs Typically this will provide a very robust solution and good software support including embedded Linux drivers The licensing fees are steep for these and can be cost prohibitive to many The source code is also often encrypted so it can not be studied for educational purposes 2 D...
