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.

Abstract: An image pickup apparatus, an image pickup method and a non-transitory computer readable recording medium are provided. The image pickup apparatus includes an image sensor including a first pixel group and a second pixel group, a controller which controls the image sensor to capture an image of an object by using the first pixel group and to capture a live view of the object by using the second pixel group, a storage which stores the image captured by the first pixel group, and an auto focusing (AF) processor which generates AF information by using the live view captured by the second pixel group.
