    摘要: An image sensor includes a pixel array including at least one active pixel and at least one line-optical black (L-OB) pixel arranged in a matrix including first to nth rows and first to mth columns, the pixel array configured to output a pixel signal and a dark-level offset signal in units of columns during a read-out operation in one of the first to nth rows; a row driver configured to output a selection control signal to the first to nth rows; and an analog-to-digital converter (ADC) block configured to digitize the pixel signal and the dark-level offset signal. In the pixel array, a dark-level offset signal is simultaneously output from an L-OB pixel in another row during the read-out operation in one of the first to nth rows. Here, ‘n’ and ‘m’ each denote an integer that is equal to or greater than ‘2’.

    摘要: An image sensor includes multiple counters and a counter controller. Each counter of the multiple counters is configured to perform counting of a comparison result signal and to generate a count result, the comparison result signal being obtained by comparing a ramp signal and a pixel signal of a column of multiple columns. The counter controller is configured to generate and transmit a counter clock signal and (n−1) delay clock signals to the counters, respectively, “n” being a natural number equal to or greater than two. Each delay clock signal of the (n−1) delay clock signals is obtained by delaying the counter clock signal by a corresponding offset code.
