.. CMOS Monochrome Digital Video Camera CHRONTEL Features - 352 x 288 monochrome active pixel array, 1/3 inch lens format - - Programmable formats CIF 352x288, QCIF 176x144, CCIR601 704x288 - Digital output CCIR601 4:2:2 (8-bit) - Multidimensional automatic shutter control - Below 1 LUX sensitivity - Programmable I2C Serial bus control: Frame rate: 30fps-1fps in eight steps Gamma correction Shutter speed Analog gain 16 backlight pensation zones Black clamp level Power down modes Description The CH5101 is a single chip active pixel CMOS monochrome video camera with digital video output in several formats. Using sophisticated noise correction circuitry to minimize fixed pattern noise and dark current effects, the CH5101 provides a supurb quality picture in a low cost device. The CH5101 uses a proprietary autoshutter algorithm to dynamically control the shutter time, analog gain, and black clamp level, providing optimum picture and contrast under all lighting conditions. The CH5101 also incorporates extensive on-chip programmable digital signal processing to maximize the usefulness of the device in processor driven applications. This includes 16 programmable zones for backlight pensation, allowing the user to adjust the image to their unique lighting environment. Additionally, at power-up the backlight pensation zone, power-up condition, and direct A/D output modes are selectable without IIC control by using the PUD pins. Requiring a minimum of parts for operation, the CH5101 provides a low cost camera for the next generation videophone, toy, and surveillance products. - Stand-alone 25fps PAL and 30fps NTSC operation with all automatic Features - Single crystal operation: Video timing on-chip - Single 5V power supply - Less than 0.5 watt power dissipation - Patent number x,xxx,xxx patents pending 352 Columns Photocell Array R O W T I M I N G Shutter Control I 2C BUS SD SC AS 288 Rows Timing & Mode Control Row...
