Confidential for truly Only
color CMOS QSXGA (5 megapixel) image sensor with OmniBSI™ technology
OV5647
proprietary to OmniVision Technologies PRELIMINARY SPECIFICATION version 1.0
5.5 post binning function
CFA image subsample will suffer zig_zag issues around slant edges and color shift for it is an non-uniform method in
physical coordinate. Post binning will map these pixels to their physically correct location.
