摘要： An imaging device includes a pixel array with a plurality of pixels each configured to generate a reset signal and an image signal, a sampling circuit including a plurality of samplers connected to column lines, where each sampler generates a first comparison signal by comparing the reset signal with a ramp signal and generates a second comparison signal by comparing the image signal with the ramp signal. An ADC converts each of the first and second comparison signals into a digital signal. Each sampler performs an auto-zero operation for initializing itself before performing the comparing with respect to the reset signal in a first mode, and performs a respective auto-zero operation before performing the comparing for each of the reset signal and the image signal in a second mode.

摘要： An electronic device includes an image signal processor and a memory. The image signal processor receives a signal of a first code value that corresponds to an active pixel included in an active area, calculates a correction value based on a second code value associated with a first area and a third code value associated with a second area, and calculates an output code value based on the first code value and the correction value. The first area and the second area are different from the active area. The correction value includes a component of the third code value in proportion to a distance between the active pixel and the first area and includes a component of the second code value in proportion to a distance between the active pixel and the second area.
