An image sensing device providing improved image quality includes a pixel array that outputs a pixel signal, a comparator that outputs a comparison result signal by comparing a reference signal and the pixel signal, a counter that outputs a count result signal having m bits by counting the comparison result signal, and an image signal processor that outputs an image signal having n bits by correcting the count result signal, wherein m and n are integers, and m is greater than n.

Image sensing device for generating an image signal by deleting bits based on a count result signal

An image sensor includes a pixel array and a readout circuit. The pixel array includes a first unit pixel region including first, second and third sub-pixel regions having a first color filter, sequentially disposed along a first row line, and sharing a first floating diffusion region, and a second unit pixel region including a first, second and third sub-pixel regions having a second color filter, sequentially disposed along a second row line, and sharing a second floating diffusion region. The readout circuit includes a first analog-digital converter receiving a first pixel signal from the first unit pixel region through a first pixel signal output line and converting the first pixel signal into digital data, and a second analog-digital converter receiving a second pixel signal from the second unit pixel region through a second pixel signal output line and converting the second pixel signal into digital data, wherein at least one of the first unit pixel region and the second unit pixel region further includes a phase detection pixel region.

Image sensor with shared floating diffusion region

An electronic device includes a pixel array that outputs a raw image including color pixels and specific pixels, a logic circuit that outputs a first binned image by performing first binning on pixels in a row direction for each unit kernel of the raw image, and a processor that outputs a second binned image by performing second binning on the first binned image. When a unit kernel includes at least one of the specific pixels, a column to which the at least one specific pixel belongs is read out at a readout timing different from a readout timing of a column to which none of the specific pixels belong and undergoes the first binning. The second binning combines a third binned image of the column to which none of the specific pixels belong with a fourth binned image of the column to which the at least one specific pixel belongs.

Electronic device and image binning method thereof

An image sensor is provided. The image sensor includes a pixel configured to generate a reset signal and an image signal, a comparator configured to compare the reset signal with a reference signal and generate a first comparison signal, a counter configured to generate a first count value corresponding to the reset signal based on a clock signal and the first comparison signal, and a reference signal generator configured to generate the reference signal which changes between a first level corresponding to a maximum reset count value of the counter and a second level corresponding to a minimum reset count value of the counter during a reset signal period.

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 first column pair and a second column pair among a plurality of columns of a pixel array, an analog-to-digital converter pair, and a switch arrangement circuit configured to connect the first column pair with the analog-to-digital converter pair in response to first switch control signals such that two rows among a plurality of rows in the pixel array are read during a single access time.

Image sensor and system including the same

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;.
