Abstract: An image sensor is provided. The image sensor includes: a pixel array of pixels arranged in a row and column directions. A first pixel provided in a first row of the pixel array includes a first sub-pixel connected with a first metal line, a second sub-pixel connected with a second metal line, a third sub-pixel connected with a third metal line, and a fourth sub-pixel connected with a fourth metal line. When a read-out operation is performed on the first pixel, signals applied to the first through fourth metal lines are sequentially enabled. Based on the applied signals, at least a part of charges accumulated in the first through fourth sub-pixels is diffused to a first floating diffusion node. The first sub-pixel and the third sub-pixel are adjacent in the column direction, and the first sub-pixel and the second sub-pixel are adjacent in the row direction.

Abstract: Provided is an image encoding method including generating a first picture reconstructed by using a residual picture and a predicted picture; generating a second picture by applying a first artifact reduction filter to the first picture; determining a picture having a smaller bit-rate distortion cost from among the first and second pictures by comparing a first bit-rate distortion cost of the first picture with a second bit-rate distortion cost of the second picture; generating a third picture by applying an in-loop filter to the determined picture; generating a fourth picture by applying a second artifact reduction filter to the third picture; determining a picture having smaller distortion from among the third and fourth pictures by comparing first distortion of the third picture with second distortion of the fourth picture; and generating, via a processor, a bitstream including information about whether the second artifact reduction filter is applied.
