OV3647 3 megapixel product brief
available in
a lead-free
package
high-performance 1/4-inch, 3 megapixel CameraChip™
sensor with MDDI high speed serial and parallel interfaces
The OV3647 is a 3 megapixel RGB raw image sensor using
OmniVision's high performance 1.75 μm OmniPixel3™
technology, with a sensitivity of 700 mV/(Lux-sec) and small
enough to enable camera module sizes of 7 x 7 x 5 mm.
The embedded image processing functions include exposure
control, white balance, defective pixel canceling and lens
shading compensation, and these are programmable
through the SCCB interface or MDDI interface.
The OV3647 is the first 3 megapixel sensor to support an
MDDI high speed serial interface. It is also equipped with a
standard parallel interface with the unique ability to act as
an input for a secondary camera and then share the MDDI
interface, i.e. also functioning as an MDDI hub. MDDI
reduces the number of interconnects to the baseband
processor, enabling rapid two-way data transfer, increasing
reliability, reducing power consumption and also eliminating
high frequency electro-magnetic interference (EMI) issues.
The OV3647 uses proprietary OmniPixel3 technology to
improve image quality by reducing or eliminating common
lighting/electrical sources of image contamination, such as
fixed pattern noise and smearing, to produce a clean, fully
stable, color image.
The OV3647 has a 3 megapixel image array, capable of
operating at 15 frames per second in QXGA (2048 x 1536)
resolution, with complete user control over image quality,
formatting and output data transfer.
The OV3647’s embedded, one time programmable (OTP)
memory is designed for part recognition and simplification
of module designs using different lenses.
