Abstract
An image signal processor that generates a display signal receives an input image signal having a first pedestal level from an image sensor, generates a first signal from the input image signal, the first signal including a second pedestal level, the second pedestal level being different from the first pedestal level and being determined in accordance with the first pedestal level and a processing gain of the image signal processor, generates a second signal having the second pedestal level by amplifying the first signal in accordance with the processing gain, generates a third signal having the second pedestal level by removing a noise signal from the second signal; and generates a fourth signal by subtracting the second pedestal level from the third signal.
