The sensor further includes a timing generator (TG), a correlated double sampling (CDS) circuit, an auto gain control (AGC) circuit and an analog-to-digital converter (ADC) circuit. With approximately 110 000 pixels (393 horizontal x 299 vertical), the sensor provides a stable digital color image with extremely low power consumption.

Total current of analog and digital power supplies, in the dark and at the standard load conditions. 8. One mean horizontal line signal <bi> is obtained by adding all the horizontal line signals <aij> vertically and dividing them by the line number. <xi> is the deviation of the center pixel from the average of successive 5 pixels in <bi>. VFPN is the maximum absolute value of <xi>. 1. The average output voltage of G signal under uniform illumination. The standard exposure conditions are defined as when VO is 150 mV. 2. The image area is divided into 10 x 10 segments under the standard exposure conditions. Each segment's voltage is the average output voltage of all pixels within the segment. PRNU is defined by (Vmax – Vmin)/VO, where Vmax and Vmin are the maximum and minimum values of each segment's voltage respectively. 3. The image area is divided into 10 x 10 segments. Each segment's voltage is the average output voltage of all pixels within the segment. VSAT is the minimum segment's voltage under 10 times exposure of the standard exposure conditions. 4.
