Method for processing image and electronic device supporting the same

A method for processing an image, performed in an electronic device including a display, the method comprising:

• generating, at a processor, first image data to be transmitted together with a first command and second image data to be transmitted together with a second command;
• transmitting, at the processor, the first image data and the second image data to a display driver integrated circuit driving the display;
• and
• storing, at the display driver integrated circuit, the first image data and the second image data separately in a memory area of the display driver integrated circuit;
• combining, at the display driver integrated circuit, the first image data with the second image data;
• outputting, at the display driver integrated circuit, the combined image data to a display panel, and
• periodically updating, at the display driver integrated circuit, for presenting time flow,
• wherein the first image data corresponds to a watch dial and the second image data corresponds to watch hands.

An electronic device comprising:

• a display panel configured to output content through a plurality of pixels;
• a display driver integrated circuit configured to transmit a driving signal for driving the display panel;
• and
• a processor configured to transmit image data and a control signal to the display driver integrated circuit,
• wherein, when the display driver integrated circuit receives first image data transmitted together with a first command and second image data transmitted together with a second command from the processor, the display driver integrated circuit is configured to store the first image data and the second image data separately in a memory of the display driver integrated circuit,
• wherein the display driver integrated circuit is configured to combine the first image data with the second image data, and output the combined image data to the display panel,
• wherein the second image data to be combined is periodically modified for presenting time flow by the display driver integrated circuit while the processor is in a sleep state, and
• wherein the first image data corresponds to a background image of a watch and the second image data corresponds to time information of the watch.
