An image sensor includes a pixel array including a plurality of pixels, a readout circuit configured to generate a digital signal from the pixel signal received from the pixel array, and a signal processor configured to determine whether to perform a binning on a first pixel group and a second pixel group among the plurality of pixels based on at least one of a first value of the digital signal corresponding to the first pixel group and a second value corresponding to the second pixel group adjacent to the first pixel group, and generate image data based on a first operation with the first value and the second value are used as operands when the binning being determined to be performed.

Image sensor with low noise and high resolution and operating method thereof

An image sensor is provided. The image sensor includes: a plurality of pixels provided in a pixel array; a controller configured to control a first pixel group of the plurality of pixels to have a first exposure integration time and a second pixel group of the plurality of pixels to have a second exposure integration time; and a signal processor configured to generate image data based on digital signals corresponding to pixel signals generated by the pixel array, by performing operations on a first value of the digital signals corresponding to the first pixel group and a second value of the digital signals corresponding to the second pixel group. The first exposure integration time of the first pixel group is independent of illuminance of the image data.

Wide dynamic range image sensor and method performed by the same

Disclosed is an image sensor including a pixel array including a plurality of pixels, each of the pixels including a first photodiode and a second photodiode, each of which outputs a first pixel signal based on a first conversion gain using the second photodiode in a first period, outputs a second pixel signal based on a second conversion gain using the second photodiode in a second period, outputs a third pixel signal based on the first conversion gain using the first photodiode in a third period, and outputs a fourth pixel signal based on the second conversion gain using the first photodiode in a fourth period, an ADC circuit that performs sampling on a reset signal and an image signal of each of the first to fourth pixel signal. A sampling count and the number of sampling bits are adjusted differently from each of the first to fourth period.

Image sensor performing selective multiple sampling and operating method thereof

An electronic circuit includes a unit pixel, a first clamp circuit, and a second clamp circuit. The unit pixel outputs a voltage having an output voltage level at a first output voltage level in a first time interval and at a second output voltage level in a second time interval different from the first time interval. The first clamp circuit is configured to clamp the output voltage level from the unit pixel to a first voltage level responsive to the first output voltage level being not greater than the first voltage level in the first time interval. The second clamp circuit is configured to clamp the output voltage level from the unit pixel to a second voltage level responsive to the second output voltage level being not greater than the second voltage level in the second time interval.
