An image sensor includes a test image generator configured to receive pixel data of a group of pixels including channel that corresponds to a size of a plurality of row regions of a pixel array that includes the plurality of row regions and a plurality of column regions, and is configured to generate test image data based on the pixel data, and an interface configured to transmit the test image data from the test image generator to a test device. The test image generator is configured to divide the pixel data into a first column region corresponding to 2n-th column region of the column regions of the pixel data and a second column region corresponding to 2n−1-th column region of the column regions of the pixel data and configured to generate a test image based on the first column region.

Image sensor, processor of image sensor, and image processing method

An interface circuit including: a first transmission circuit outputting a first signal to a transmission line via first transfer pads; and a second transmission circuit outputting a second signal to the transmission line via second transfer pads, the first transmission circuit includes a first termination resistor block including a switch and a first termination resistor connected between the first transfer pads, the second transmission circuit includes a second termination resistor block including a switch and a second termination resistor connected between the second transfer pads, and when the first transmission circuit outputs the first signal, the second termination resistor block detects the first signal, and when the first transmission circuit is in a low-power operation mode, the second termination resistor block disconnects the second termination resistor, and when the first transmission circuit is in a high-speed data transfer mode, the second termination resistor block connects the second termination resistor.

Interface circuit for controlling output impedance of a transmission circuit and an image sensor including ihe same

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.
