摘要： A digital white balance device is simply implemented in a digital processing scheme by employing a grey world algorithm. In the device, a timing controller receives vertical and horizontal synchronization signals of an input image and produces a timing control signal. An RGB multiplier multiplies input RGB image data by RGB gains received from an RGB gain controller. A first YCbCr averaging unit converts input RGB image data to YCbCr image data, and obtains first YCbCr averages of this YCbCr image data. A second YCbCr averaging unit converts output RGB image data to YCbCr image data, and obtains second YCbCr averages of this YCbCr image data. According to the timing control signal, the RGB gain controller compares the second YCbCr averages with predetermined target YCbCr averages, respectively, and obtains RGB gains based on the first YCbCr averages, according to the compared result, and provides them to the RGB multiplier.

摘要： In a CMOS image sensor of the invention, a dynamic range is varied at a per-pixel level by a light amount to prevent saturation without degrading color reproduction of an overall image. A photo diode generates charges in accordance with a received light amount. A drive transistor amplifies the charges generated in the photodiode at a given gain. Further, a saturation detector receives an output voltage from the drive transistor and judges the image sensor saturated if the output voltage is beyond a limited level. A switch switches on/off in response to the judgment of the saturation detector. Also, a plurality of floating diffusions store the charges of the photodiode transferred through the switch. The floating diffusions are selectively connected to both the photodiode and a gate of the drive transistor at on/off the switch.
