Abstract: Image sensors include an array of image sensor pixels therein. This array of image sensor pixels includes a first focus detection pixel and at least a first color pixel. A switching network is provided, which is electrically coupled to the array. This switching network may be configured to generate a first mixed image signal by electronically mixing a focus detection signal generated by the first focus detection pixel with at least one color pixel signal generated by the at least a first color pixel. The first focus detection pixel can be a color-blind pixel, which may include a light-blocking shield mask therein.

Abstract: An image sensor includes a pixel array and N analog-to-digital converters (ADCs). The pixel array includes N pixels arranged in each of a plurality of rows, and each of the N pixels include M photoelectric conversion elements. At least one of the N ADCs are shared by at least one of the M photoelectric conversion elements included in each of the N pixels.

Abstract: An image sensor and an image processing system including the same are provided. The image sensor includes a pixel array including a plurality of pixels each connected to one of first through m-th column lines to output a pixel signal, where “m” is an integer of at least 2; analog-to-digital converters each configured to receive the pixel signal corresponding to one of the first through m-th column lines, to compare the pixel signal with a ramp signal, and to convert the pixel signal to a digital pixel signal; and a blocking circuit connected to an input terminal of at least one of the analog-to-digital converters to block an influence of an operation of others among the analog-to-digital converters.

Abstract: An image sensor includes a pixel array including first to fourth pixels having an R, G, and B Bayer pattern. An analog-to-digital converter (ADC) block converts a pixel signal of each of the first to fourth pixels into a digital pixel signal. At least one among the first to fourth pixels includes two photo diodes separated in a first direction, and at least one other of the first to fourth pixels includes two photo diodes separated in a second direction which is different from the first direction.
