Abstract: An image sensor includes a Bayer pattern-type pixel array including a plurality of Bayer pattern-type extended blocks each having first to fourth pixel blocks, each of the first to fourth pixel blocks including first to fourth pixels, the first and fourth pixels of the first and fourth pixel blocks being configured to sense green light, the first and fourth pixels of the second and third pixel blocks being configured to sense red light and blue light, respectively, and the second and third pixels of the first to fourth pixel blocks being configured to sense white light, and a signal processing unit merging Bayer pattern color information generated from the first and fourth pixels of the first to fourth pixel blocks, and the Bayer pattern illuminance information generated from the second and third pixels of the first to fourth pixel blocks.

Abstract: An image processing method of an image signal processor includes obtaining a first estimated image by interpolating signals output from first color pixels, among a plurality of unit pixels included in a pixel array, in a first direction, obtaining a second estimated image by interpolating signals output from the first color pixels in a second direction, intersecting the first direction, detecting a first artifact component in the first direction with respect to pixels included in the first estimated image, detecting a second artifact component in the second direction with respect to pixels included in the second estimated image, obtaining a first weight based on at least a portion of the first artifact component and the second artifact component, and generating a first output image from the first estimated image and the second estimated image using the first weight.
