Abstract: An image processing device includes an image sensor including a pixel array that includes a first pixel group, and a correlated double sampling circuit. The first pixel group includes a first plurality of normal pixels, a second plurality of normal pixels, and at least one first phase detection pixel. The correlated double sampling circuit is configured to generate first video data, based on charges of the first plurality of normal pixels, generate second video data, based on charges of the second plurality of normal pixels, and generate first phase detection data, based on an output of the at least one first phase detection pixel. The image processing device further includes an image signal processor configured to apply a first weight to the generated first video data, and apply a second weight to the generated second video data.

Abstract: Disclosed is a camera module which includes an image sensor including pixels outputting raw image data based on light incident from at least one of a display or the exterior, and control logic receiving the raw image data and generating image data. In a first operation mode, the control logic turns off calibration of the image sensor, receives first raw image data, which are based on the light incident from the display, from the image sensor, and generates crosstalk calibration data based on first output values included in the first raw image data. In a second operation mode, the control logic turns on the calibration of the image sensor, receives second raw image data, which are based on light incident from the display and the exterior, from the image sensor, and generates the image data based on second output values included in the second raw image data.

Abstract: A system for testing whether or not an image sensor included in an image frame is defective includes including a processor configured to execute machine-readable instructions that, when executed by the processor, cause the test device to generate a test image by performing one or more preprocessing operations on a raw image output from an image sensor, and to classify an image pattern of the test image as any one of patterns included in a first data set by using a first deep learning neural network trained based on the first data set and to determine, based on a classifying result, whether or not the image sensor is defective. The first data set comprises a data set for each pattern, classified to correspond to each of one or more defect patterns and to a normal pattern of an image.
