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.

Abstract: A method of operating an electronic device includes receiving a plurality of reference code values respectively corresponding to a plurality of reference images captured by an image sensor during different exposure times, receiving a plurality of target code values corresponding to a target image captured by the image sensor, estimating an inverse camera response function (CRF) by adjusting a scale of the plurality of reference code values so that the scale of the plurality of reference code values is equal to a scale of the inverse CRF, wherein the inverse CRF estimates radiance corresponding to the plurality of reference code values, generating a radiance map based on the plurality of reference code values and the inverse CRF, and measuring an effective dynamic range (DR) length of the image sensor based on the radiance map and the plurality of target code values.

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.
