Electronic device, and method for electronic device compressing high dynamic range image data

Abstract

Various embodiments of the present invention relate to an electronic device comprising: a processor; an image sensor that includes a first sensor pixel set and a second sensor pixel set; and a control circuit that is electrically connected to the image sensor, wherein the control circuit can be configured so as to obtain raw image data by using the image sensor in which the exposure of the first sensor pixel set and the exposure of the second sensor pixel set are configured differently, divide the raw image data into first channel data corresponding to a first color and second channel data corresponding to a second color, generate first channel compression data that are compressed on the basis of the first channel data such that at least a part of data obtained using the first sensor pixel set adjoins and at least a part of data obtained using the second sensor pixel set adjoins, generate second channel compression data that are compressed on the basis of the second channel data such that at least a part of the data obtained using the first sensor pixel set adjoins and at least a part of the data obtained using the second sensor pixel set adjoins, and transmit the compressed first channel compression data and the compressed second channel compression data to the processor. In addition, among the various embodiments of the present invention other embodiments may be possible.
