ADDRESS NAME BITS
FUNCTION
04h
2 Option of output mode.
OUT_SEL (7) 00 : QCIF1
01 : CIF
(6) 10 : QVGA
11 : QCIF2
2 Clock timing for input.
IN_TIM (5) 00 : Delayed by one CK 01 : Delayed by two CK
(4) 10 : Not delayed
4 0000 : CIF image output with CKI clock of CMOS image sensor
(3) 0001 : 1 frame of image output per second with CKI clock
(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.
