Abstract: An electronic device is provided. The electronic device includes a first camera, a display, a second camera disposed below the display, and at least one processor, wherein the at least one processor is configured to acquire first image data and first environment information associated with the first image data by using the first camera, acquire second image data and second environment information associated with the second image data by using the second camera, determine whether to correct a correction value related to the second camera based on the second image data, the correction value including at least one of a white balance correction value for correcting white balance of the second camera or a lens shading correction value for correcting lens shading of the second camera, identify a similarity between the first environment information and the second environment information in response to determining to correct the correction value related to the second camera, and correct the correction value related to the second camera by using at least the similarity based on the first image data.

Abstract: An image processing circuit, an image signal processor including the same, and an image processing method are disclosed. The image processing circuit may include a contents-aware circuit configured to receive histograms of a current image and a previous image, classify content for each pixel of the current image, and generate a shifting value representing a color shifting effect for each pixel of the current image, a color shifting circuit configured to generate an enhanced image by applying color shifting depending on the shifting value to each pixel of the current image, based on the shifting value, and a histogram generator configured to generate a histogram of the current image based on the classified content of the current image, wherein the generated histogram of the current image is used to generate a shifting value of a subsequent image.
