Chapter 3
Using the D8M Board
his chapter provides instructions on how to use the MIPI camera module, MIPI
Decoder and GPIO connector on the D8M board.
3.1 MIPI Camera Module
Terasic D8M board equips with an 8M pixel MIPI camera module named OV8865 (See
Figure 3-1). The OV8865 color image sensor is a high performance, 8 megapixel RAW
image sensor that delivers 3264x2448. It provides options for multiple resolutions while
maintaining full field of view. Users can program image resolution, frame rate, and
image quality parameters. Camera functions are controlled via I2C bus
(CAMERA_I2C_SDA and CAMERA_I2C_SCL). The I2C device address is 0x6C.
Figure 3-1 MIPI Camera Module
Figure 3-2 shows a cross-section of the image sensor array. The color filter is
arranged in a Bayer pattern. Of the 8,332,288 pixels, 7990,272 (3264x2448) are active
pixels and can be output. The other pixels are used for black level calibration and
interpolation.
