(12) Reset Level Control Register (Address 30h, default:38h, R/W)
This register controls reference voltage level for start point of data reading. If the register value is too large or
too small, the vertical Fixed Pattern Noise(FPN) can be occurred. To Get rid of FPN, this register must have a
suitable value. Optimum reset revel can be found using Low reference number registers 57h ~ 58h and High
reference number registers 59h ~ 5ah. If there is some large value in Low reference number registers, the
value of Reset Level control register should be increased. If there is some large value in High reference
number registers, the value of register should be decrease. Optimum reset revel is achieved when value of
Low reference level number registers and value of High reference number registers is minimized.
(13) Color Gain Register
Red Color Gain Register : (Address 31h, default:1Eh, R/W)
Green Color Gain Register : (Address 32h, default:h1Eh, R/W)
Blue Color Gain Register : (Address 33h, default:h1Eh, R/W)
These registers are used to amplify the analog pixel output. If the gain register value is decreased, the
amplification is increased. Therefore under the dark light source condition, the pixel output have to be amplified
by decreasing gain value to get good image. There are three Gain registers to control RGB colors
independently. In the case of monochrome image sensor, use only Green Color Gain Register. Available
program range is 0 ~ 63 but too small value can cause FPN. The register value have to chosen within the range
that doesn’t cause FPN. Recommended range is 20 ~63. These register can be used for Auto White Balance
control and Auto Exposure control.
(14) Pixel Bias Voltage Register (Address 34h, default:02h, R/W)
This register controls pixel reference level by controlling bias current of pixel output sensing load transistor. It
controls pixel output level itself, compare with that revel register adjust A/D Converter circuit to calibrate
reference level for data reading. Available program range is 0 ~ 7. The larger register value causes the higher
bias current and low pixel output reference level. This register is option for manufacturer. Users may use default
setting and don’t changed value.
