High-Speed VGA Image Sensor for Video, Gaming
and Portable Entertainment
The OV7735 is an advanced VGA image sensor that can
capture video at 60 frames per second (fps) enabling
smoother motion video and achieve improved accuracy for
motion detection applications. Implementing OmniVision's
proven 3.0 µm OmniPixel3-HS™ high sensitivity pixel
architecture ensures high quality video recording even in
the most challenging lighting conditions, achieving lowlight performance of 3300 mV/lux-sec. The image sensor's
design enables some of the thinnest (<3 mm) VGA camera
solutions capable of high-speed recording, making the
OV7735 ideal for portable applications including digital
video cameras, portable media players (PMPs), gaming
devices and webcams.
The OV7735 offers complete user control over image
quality, resolution and output data format. The OV7735
provides full frame, sub-sampled, windowed or scaled
8-bit/10-bit images in RAW RGB and YUV formats over
a parallel DVP or serial MIPI port, offering a versatile
platform for use in single and multi-camera applications.
All required image processing functions, including
exposure control, white balance, and defective pixel
detection and correction are programmable through the
serial camera control bus (SCCB) interface. The OV7735
also addresses image contamination issues such as fixed
pattern noise, smearing and blooming, producing a clear,
crisp color image. Designed largely for portable or wireless
applications, the new sensor offers low power
consumption, requiring just 100 mW under normal
operating conditions.
