摘要： 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.

摘要： Disclosed is a camera module. The camera module includes an image sensor that captures an image of a target to generate first image data, outputs the first image data, and outputs an interval information signal; an image signal processor that receives the first image data, performs image processing on the first image data to generate second image data and outputs the second image data; and an interface circuit that receives the second image data and the interval information signal and outputs the second image data as third image data. The interface circuit adjusts a timing to output the third image data, based on the interval information signal.

摘要： 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.

摘要： An image sensor includes a pixel including a reset circuit and a floating diffusion node, and outputting a pixel signal that is generated based on a voltage at the floating diffusion node, the pixel signal including a reset output that is generated based on the voltage at the floating diffusion node being reset by the reset circuit. The image sensor further includes a sampler sampling the output pixel signal to generate a sampling signal having a time interval corresponding to a magnitude of the output pixel signal, and a counter counting the generated sampling signal, based on a counter clock, to generate a counting value corresponding to the time interval of the sampling signal. The sampler samples the reset output of the output pixel signal n times to generate first to n-th reset sampling signals, where n is an integer of 2 or more.

摘要： An electronic device includes an image signal processor and a memory. The image signal processor receives a signal of a first code value that corresponds to an active pixel included in an active area, calculates a correction value based on a second code value associated with a first area and a third code value associated with a second area, and calculates an output code value based on the first code value and the correction value. The first area and the second area are different from the active area. The correction value includes a component of the third code value in proportion to a distance between the active pixel and the first area and includes a component of the second code value in proportion to a distance between the active pixel and the second area.

摘要： Disclosed is an image sensor device which includes a pixel that outputs a first pixel signal to a first column line during a first time period and outputs a second pixel signal to the first column line during a second time period, and a clamp circuit that outputs a first clamp signal to the first column line during the first time period. During the first time period, a voltage of the first column line is determined based on the first pixel signal and the first clamp signal. The pixel operates based on a first power supply voltage, and the clamp circuit operates based on a second power supply voltage lower than the first power supply voltage.
