• Manufacturer Part Number: ICM-205BSA
• Description: VGA/QVGA CMOS image sensor with digital YUV output
• Manufacturer: ETC1 [List of Unclassifed Manufacturers]

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
The following registers:
0x28 (AD_CONTRAST, Default = 0x20)
Unsigned 1.5 format(bit5~bit0).
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.
