1/7” CIF CMOS IMAGE SENSOR

Figure 8. Recommended Minimum Global Gain Control Value

By appropriately programming these four register values, the different output resolution according to the signal

can be achieved and the intra-scene dynamic range can be increased by 16 times. In another application, the

sectional global gain control can be used as a rough gamma correction with four sectional linear approximation

curve as shown in Figure 9.

3. Post Processing

3-1. Dark Level Compensation

The dark level of Image sensor is defined as average output level without illumination. It includes pixel ouput

caused by leakage current of the photodiodes and ADC offset. To compensate the dark level, the output level of

optical black(OB) pixels can be a good reference value. When Auto Dark Level Compensation Register (dlcm) is

set, the image sensor detects the OB pixel level at the start of every frame and anglog-to-digital conversion range

is shifted to compensate the dark level for that frame. So, the resulting output data of that frame will be almost zero

under dark state. If user wants the dark level which is not zero, the ADC Offset Register (adcoffs) can be used.

The lower 7-bit value represent the offset value in outout code for compensation and the MSB is the sign to define

whether the offset is positive (adcoffs[7]=0) or negative (adcoffs[7]=1). When not in auto dark level

compensation mode, the adcoffs[7:0] act as a output code value to subtract the output image data. Please notify

that the all the 8-bit data are used for an offset value without sign bit.

3-2. Bad Pixel Replacement

When the Bad Pixel Replacement Register (bprm) is enabled, the image sensor check that the image data is

less or greater than horizontally neighboring pixels in same color channel by the preset threshold value (pthresh).

If satisfied, the output of the pixel is replaced by the averaged value of the neghiboring two pixels. The detectable

defected pixels are rare and the bad pixel replacement action can remove defected image effectively. But it

reduces the line resolution in horizontal direction.
