Holtek HT82V863R CCD监控摄影机处理方案
Holtek(盛群半导体)公司的HT82V863R是新一代的 CCD监控摄影机处理器, 采用更精简的 64LQFP封装, 新的影像处理器在低照,色彩及噪声等各项影像处理上，其性能都比 HT82V862R 优秀,提供数字式高动态处理,自动背光补偿及数字式线锁定同步等功能.本文介绍了HT82V863R主要特性,方框图以及系统应用框图.
The HT82V863R is a single chip digital image processor for Ye, Cy, Mg and G colour CCD video camera systems. It receives CFA patterns from colour CCDs and generates NTSC/PAL CVBS signals using internal video encoders and the 10-bit DAC. In addition, it also provides an AE/AWB algorithm, timing generation module together with other circuitry. The device contains a microcontroller in which an OTP ROM is integrated internally to implement the basic camera functions such as the AE/AWB algorithm. The video camera system consists of a CDS/AGC/ADC IC (HT82V842A), DSP IC (HT82V863R), Vertical Driver IC (HT82V805) and CCD sensors. It also provides a proprietary function to eliminate so called “line crawl” and automatic CCD defect compensation function to correct up to 30 bad pixels and 4 consequential bad pixels.
HT82V863R主要特性:
• Input: Supports Ye, Mg, Cy, G colour filters for NTSC/PAL, 270K/320K/410K/470K CCD sensors
• Output: NTSC/PAL Analog CVBS
