An image sensor is disclosed. The image sensor includes a plurality of pixels, a switch circuit coupled to the pixels and configured to substantially simultaneously output signals output only from pixels having similar characteristics among the pixels in response to a control signal; and a comparison circuit configured to convert the signals output from the switch circuit into digital signals. The pixels having similar characteristics are located across among the plurality of pixels.

Image sensor for performing coupling-free readout, and device having the same

An image sensor includes a pixel array including a plurality of pixels, a row driver configured to control an operation of each of the plurality of pixels, a voltage supply line connected to a reset transistor included in each of the plurality of pixels, and a voltage supply circuit which detects a signal from the voltage supply line and supplies one of a first voltage and a second voltage to the voltage supply line based on the signal from the voltage supply line.

Image sensor for supplying a different voltage to pixels based on illumination change, operation method thereof, and device having an image sensor

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 nrows and first to mcolumns, 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 nrows; a row driver configured to output a selection control signal to the first to nrows; 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 nrows. Here, 'n' and 'm' each denote an integer that is equal to or greater than &#x2018;2&#x2019;.
