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 I2CTM 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.
