Abstract
Various embodiments provide an electronic device and a method for controlling an operation of the electronic device. An electronic device according to various embodiments of the present invention may comprise: a lens unit; an image sensor; a memory used for intra-prediction of an image captured using the image sensor, and storing direction modes differently configured according to characteristics of a partial area of the lens unit; and a processor, wherein the processor: acquires a raw image corresponding to an external object by using the image sensor; divides the raw image into multiple blocks; selects a block, on which intra-prediction is to be performed, from among the multiple blocks; determines a direction mode to be used for intra-prediction of the selected block on the basis of a distortion parameter of a partial area of the lens unit corresponding to the selected block; performs the intra-prediction on the selected block on the basis of the determined direction mode; and generates a compressed image corresponding to the raw image on the basis of a result of the intra-prediction. In addition, various embodiments are possible.
