Abstract: 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.

Abstract: 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.
