ICM205B: VGA CMOS sensor with digital YUV output
Data Sheet V1.3, Oct. 2002
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.
