An apparatus for panning and scaling a window in CMOS image sensor is described.
The apparatus comprises a pixel array having a plurality of unit pixels, a row
driving part, an analog-digital converting part, an address generating part for
generating a row address and a column address for the panning and scaling, and
a line buffering part for receiving the digital pixel data outputted from the analog-digital
converting part and outputting a pixel data according to the column address. According
to the apparatus, CMOS image sensor can directly extract a pixel data of a desired
resolution and scale offset.
