LR38630
DESCRIPTION
The LR38630 is a CMOS digital signal processor
for color camera systems of 110 k-pixel CMOS
image sensor with primary color mosaic filters. The
camera system consists of CIF CMOS image
sensor (LZ34C10) and DSP IC (LR38630) with 2 k-
bit EEPROM. Depending on application, 1 M-bit
SRAM can be added in order to get slower frame
rate at video output.
FEATURES
• Designed for 110 k-pixel color CMOS image
sensors with R, G, and B color mosaic filters
• Compatible with CIF standard
• External control interface input/output
• Variable GAMMA and KNEE response
• 8-bit digital input
• Available for digital video 4 : 2 : 2 (U/Y/V/Y)
output
• Built-in synchronous signal generation circuit to
drive CMOS image sensor
• Built-in 2 k-bit EEPROM controller to set the
camera adjustment data
• Built-in auto exposure control
• Built-in auto white balance control
• Built-in auto carrier balance control
• Built-in white blemish compensator
• Lower power consumption by dual clocking signal
process technology
• Single +3.0 V power supply
• Package :
80-pin LQFP (LQFP080-P-1212) 0.5 mm pin-pitch
