General Description
This is a single-chip digital color imaging device. It incorporates a 640 x 480 sensor array operating at max. 30 frames per second in progressive manner. Each pixel is covered by a color filter, which formed a so-called Bayer pattern. Correlated double sampling is performed by the internal ADC and timing circuitry. Depending on the brightness of the scene, the raw data can be adjusted by the digital gain for all pixels, or be adjusted separately for the 4 Bayer pattern pixels. This is done either by the built-in automatic exposure control circuit, or can be done manually by the external CPU via serial bus control. The data are then processed by the color interpolation module so that each pixel will get a complete set of RGB values. To correct or enhance color, automatic white balance circuit is built-in. The user may perform white balancing and color correction manually by external CPU via serial bus too. Color saturation control is programmable via serial bus, if user is not satisfied with the default settings At the final stage, the gamma correction can also be performed, in addition to default value. The output formats include 8/16-bit YCbCr, 24-bit, 16-bit RGB, and 8-bit raw data which can be fed to other DSP, color processing, or compression chips.

Functional Description Image Array
The image array consists of 640x480 pixels. Each pixel has a light sensitive photo diode and a set of control and transfer transistors. At the beginning of the cycle, a row of pixels are pre-charged to its maximum value. Then they are exposed to light for several lines worth of time and sampled by the ADC. Correlated double sampling (CDS) is performed by subtracting the reset value (sampled right before sampling the signal) from the signal value. The purpose of CDS is to eliminate the point-wise fixed pattern noise (FPN). The output of CDS is approximately proportional to the amount of received light, ranging from 0 to 255.
Color Filter
Each pixel is covered by a color filter. They form the Bayer Pattern as shown in Figure 2. (Row 0, Column 0) is covered by a Red filter, (Row 0, Column 1) and (Row 1, Column 0) by Green filters, and (Row 1, Column 1) by a Blue filter. Since each pixel only gets part of the frequency band, the data need further processing (i.e., color interpolation and color correction) in order to approximate the full visible spectrum.

Exposure and Gain Control
The brightness of the scene may change by a great amount that renders the captured image either over-exposed or under-exposed. To accommodate for different brightness, the user may change the exposure time by adjusting the AD_EXPOSE_TIMEH, and AD_EXPOSE_TIMEL. The exposure time is measured in terms of the time to read out one line of data, which is equal to 64 s (assuming the line length is 770 @ 24 MHz). If the number of lines per frame is set at 520 (the default), the exposure time can vary from 1 to 519 lines.
50/60Hz anti-flickering control
To eliminate the flickering caused by the 50Hz or 60Hz light source normally found indoor, an anti-flickering control circuit is build in. The selection is between off and on. When it is on, then the selection is between 50 or 60Hz.

Auto Exposure
The Auto Exposure circuit control the Exposure Time, Digital Gain, and Anti-flickering function automatically. The following features are provided: . Disable/Enable AE . Disable/Enable Anti-flickering . Disable/Enable Digital Gain . Disable/Enable Fix Frame Rate . Adjustable Maximum/Minimum Frame Rate . Adjustable AE Target brightness value The following registers are use to control these features: 0x3A (AD_AE_CTRL, Default = 7) bit 0 : Disable/Enable AE bit 1 : Disable/Enable Digital Gain bit 2 : Disable/Enable Anti-flickering bit 3 : Disable/Enable Fix Frame Rate The default value enable AE, Anti-flickering, and Digital Gain. 0x3B (AD_AE_HIGH,AE Target value High Limit, Default = 0x65) 0x3C (AD_AE_LOW,AE Target value Low Limit, Default = 0x55) Use AD_AEHIGH and AD_AELOW to set the target brightness of AE function. 0x3F,0x40 (AD_MAXFH, Maximum Frame Height, Default = 0x1450) AD_MAXFH set the minimum frame rate of AE . 0x41,0x42 (AD_MINFH, Minimum Frame Height, Default = 0x208) AD_MINFH set the maximum frame rate of AE . 0x44 (AD_AFSTEP, Anti-flickering Exposure Time Step, Default = 0x82) Use AD_AFSTEP to setup 50 /60HZ Anti-flickering step.
Color Interpolation
Since the raw data coming out the sensor array has only one of the R, G, or B value for each pixel, we need to perform interpolation to obtain a set of correlated RGB value for each pixel. The method used is based on a 3x3 interpolation window. The result of this operation is a data stream consisting of 24-bit RGB per pixel. After this step, the whole frame can be viewed as a color picture. However, since the RGB filters and the photodiode are not perfect, the RGB values may have different strength. In addition, there are some cross-talk among the RGB channels. That's why we need the color correction (or white balancing) step.

Auto White Balancing
Due to the different transparency and the overlapping spectrum response of the R, G, and B filters, the interpolated color may not be balanced. The Auto White Balancing performs the White Balance function automatically . The following register are used to control the AWB function: 0x33 (AD_AWB_CTRL, Default = 3) 0 : Disable AWB 1 : Enable AWB with R,G,B range limited 3 : Enable AWB with no range limited 0x34 (AD_AWB_OVERFLOW, Default = 255) Set the overflow value of the sampling pixel, if the sampling data is larger than AD_AWB_OVERFLOW, then it will not be used for AWB processing. The default value 255 means there is no limit on sampling data. 0x35 (AD_AWB_BRIGHT, Default = 0) Set the minimum bright value of the sampling pixel, if the sampling data is less than AD_AWB_BRIGHT, then it will not be used for AWB processing. The default value 0 means there is no limit on sampling data. When AWB function is disabled, the following registers are used to adjust the White Balance manually: 0x37 (AD_WB_RED, Default = 0x80 ) Set the RED Gain manually. 0x38 (AD_WB_GREEN, Default = 0x80) Set the GREEN Gain manually. 0x39 (AD_WB_BLUE, Default = 0x80) Set the BLUE Gain manually.
Sharpening
The following register are used to control the Sharpening function: 0x30 (AD_SHARP_CTRL, Default =9) 0 : Disable Sharpening. 8 : Sharpen Weight = 0.5 (light Sharpening) 9 : Sharpen Weight = 1 (default) a : Sharpen Weight = 2 b : Sharpen Weight = 3 c : Sharpen Weight = 4 d : Sharpen Weight = 5 e : Sharpen Weight = 6 f : Sharpen Weight = 7 (heavy Sharpening) 0x31 (AD_SHARP_HIGH,Default =0x0a) Sharpening High Tone Threshold. 0x32 (AD_SHARP_LOW,Default = 0x05) Sharpening Low Tone Threshold.

ICM205B: VGA CMOS sensor with digital YUV output Data Sheet V1.3, Oct. 2002
Color saturation control
The color saturation can be enhanced by adjusting the Saturation Factor register 0x2D (AD_SATURATION, Default = 0x30). The following examples show how to set the Saturation to 0, 1, 1.5, and 2: Saturation 0 : AD_SATURATION = 0x00, no color (B/W) 1 : AD_SATURATION = 0x20 1.5: AD_SATURATION = 0x30 2.0: AD_SATURATION = 0x40
Gamma Correction
To boost darker signal to match the video monitor characteristic, gamma correction are performed:
Vo = Vi1 /
where Vi is normalized (ranged from 0 to 1) R, G, or B signal coming from the white balancing module, and Vo is normalized final output. The Gamma values (parameter ) are provided in 205B, use register 0x2c (AD_GAMMA) to select one of them: AD_GAMMA 0 : Gamma = 1 (no Gamma) AD_GAMMA 1 : Gamma = 1.3 AD_GAMMA 2 : Gamma = 1.5 AD_GAMMA 3 : Gamma = 1.7 AD_GAMMA 4 : Gamma = 1.9 AD_GAMMA 5 : Gamma = 2.2 AD_GAMMA 6 : Gamma = 2.5
Brightness
The Brightness offset can be adjusted by Brightness Offset register 0x2B (AD_BRIGHT_OFFSET, Default =0). The default value =0 means the Brightness is not adjusted. The following examples show how to increase/decrease the Brightness Level: Increase Brightness by 10: AD_BRIGHT_OFFSET = 0x0A Decrease Brightness by10: AD_BRIGHT_OFFSET = 0x8A

Hue
The Hue function is used to change the image color temperature. The color temperature is changed by rotating the (U,V) vector: U' = U * COS + V * SIN V' = U * COS - V * SIN The value of COS and SIN is define in the following registers: 0x29 (AD_SIN, Default = 0) The SIN value. Default = 0x00 is equal to AD_SIN = 0. 0x2A (AD_COS, Default = 0x7F) The COS value. Default = 0x7F is equal to AD_COS = 1.
Contrast
The Contrast function is control by the following function Y' = Y * CONTRAST The following registers: 0x28 (AD_CONTRAST, Default = 0x20) Unsigned 1.5 format(bit5~bit0).
Output Format
The following output data format is provided: 8-bit YCbCr 16-bit YCbCr 16-bit RGB 24-bit RGB 8-bit raw data The output mode can be VGA or Sub-sampling QVGA and QQVGA. Register 0x52 (AD_OUTSEL) is used to select the various output format and output mode.
