Abstract: A method for evaluating performance of an image signal processor according to various example embodiments includes: selecting at least two target colors from an original image generated by the image signal processor; defining a true color range in each of the target colors and identifying at least one false color pixel having a color deviating from the true color range in the original image; generating a reference image by changing a color of the false color pixel; and calculating a color error between the original image and the reference image.

Abstract: An image sensor including an image signal processor and an operating method of the image sensor are provided. An image sensor may include a pixel array configured to convert a received optical signal into electrical signals, a readout circuit configured to analog-digital convert the electrical signals to generate image data, and an image signal processor configured to perform one-dimensional filtering in each of a first direction and a second direction on the image data to remove noise of the image data, the second direction being different than the first direction.

Abstract: An image signal processor may be configured to process an image based on simultaneously performing auto zoom and auto focus. An image signal processor may be configured to receive a first image from an image sensor may include processing circuitry configured to determine auto focus information on an object in the first image using a depth map, set a first area based on calculating a first outer point and a second outer point associated with the object using the depth map, set a second area based on a particular ratio that is determined based on the first outer point and the second outer point, and determine auto zoom information based on calculating a zoom ratio corresponding to a size of the second area.
