Overview
The OV5017 is a black and white digital camera
chip that uses OmniVision’s CMOS image core
technology. Combining the CMOS sensor technol-
ogy and an easy to use digital interface, the
OV5017 offers a low cost solution for high-quality
video image applications.
The digital video port supplies a continuous byte-
wide image data. On-chip programmable features
include variable frame rate, exposure setting, and
image size. All the camera features are register
based, accessing the video data and configuring
the chip is as easy as read/write of a static mem-
ory.

registers affects the basic camera operation, care must be taken when write occurs during the middle of
active window. These effects are described in the individual register section. As a guide line, registers
affects the frame rate, exposure time, window size, are better updated during the vertical sync
