This reflects the actual layout of the array on the die. Also, the first pixel data read out of the sensor in default condition is that of pixel (112, 44). When the sensor is imaging, the active surface of the sensor faces the scene as shown in Figure 6. When the image is read out of the sensor, it is read one row at a time, with the rows and columns sequenced as shown in Figure 6. Figure 6. Imaging a Scene Lens Pixel (0,0) Row Readout Order Column Readout Order Scene Sensor (rear view) Digital Gain Control MT9M034 supports four digital gains for the color channels: Red, Green1 (green pixels on the red rows), Green2 (green pixels on the blue rows), and Blue. Digital gain control of the MT9M034 is dependent on the configuration of the x_addr_start register. Table 4 illustrates how the digital gains are applied when x_addr_start is even or odd number.
