PAS005B
PAS005B SXGA Color/Mono Digital CMOS Image Sensor
General Description
The PAS005B is a highly integrated CMOS active-pixel image sensor that has a SXGA resolution of 1280(H) x
1024(V). To have an excellent image quality, the PAS005B outputs 10-bit RGB raw data through a parallel data
bus. It is available in color or monochrome in 48-pin LCC.
The PAS005B can be programmed to set the exposure time for different luminance conditions via I²C^TM serial
control bus. By programming the internal register sets, it performs on-chip frame rate adjustment, offset correction
DAC, programmable gain control, 10-bits ADC, 8-bits output companding, interpolated sub-sampling and defect
compensation.
