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

(2) 0010 : 2 frames of image output per second with CKI clock
(1) 0011 : 15 frames of image output per second with CKI clock
(0) 0101 : 1 frame of image output per second with EXCK clock
(1 frame data is written to RAM in vertical blanking.)
ACT_MODE
0110 : 2 frames of image output per second with EXCK clock
(2 frames data are written to RAM in vertical blanking.)
0111 : Image output with EXMCK clock
(EXMCK should be lower than 4.5 MHz.)
1XXX : Except 0000, works with 30 frames after power-on.
(example) 1001 : 1 frame of image output per second with CKI starting
with 30 frames after power-on.
1000 : Prohibited to use
05h 8 Setting a period to work with 30 frames after power-on.
ACT_TIM
A period = (Data + 1) x frame rate
06h REF_IRIS 8 Electronic exposure reference level.
07h 8 The second target area of electronic exposure control.
CTLD_01
In the case that exposure control data is within (data of address 06h ± data of
address 07h), the exposure control is completed.
08h 8 The first target area of electronic exposure control.
CTLD_02
If exposure control data is over (data of address 06h ± data of address 08h), the
exposure control is restarted.
09h REF_BLC 8 Exposure reference level in BLC (valid with BLC of address 03h = 1).
0Ah 8 The second target area of electronic exposure control in BLC.
CTLD_11
In the case that exposure control data is within (data of address 09h ± data of
address 0Ah), the exposure control is completed.
0Bh 8 The first target area of electronic exposure control in BLC.
CTLD_12
If exposure control data is over (data of address 09h ± data of address 0Bh), the
exposure control is restarted.
