3 megapixel product brief
OV3647
high-performance 1/4-inch, 3 megapixel CameraChip™
sensor with MDDI high speed serial and parallel interfaces
available in
a lead-free
package
The OV3647 is a 3 megapixel RGB raw image sensor using
OmniVision's high performance 1.75 μm OmniPixel3™
The embedded image processing functions include exposure
control, white balance, defective pixel canceling and lens
technology, with a sensitivity of 700 mV/(Lux-sec) and small shading compensation, and these are programmable
enough to enable camera module sizes of 7 x 7 x 5 mm.
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’s embedded, one time programmable (OTP)
memory is designed for part recognition and simplification
of module designs using different lenses.
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.
