Abstract: Disclosed is an image data compression method including calculating an estimated error of each of a plurality of compression modes for compressing image data based on the image data and a weighted value in each sub-pixel, selecting one mode among the plurality of compression modes based on the estimated error of each of the plurality of compression modes, and encoding the image data according to the selected mode.

Abstract: Disclosed is an image data compression method including determining whether image data can be compressed by a target compression ratio using one of at least one lossless compression scheme for compressing image data, when the image data can be compressed by the target compression ratio using the one of the at least one lossless compression scheme, encoding the image data using the one of the at least one lossless compression scheme, and when the image data cannot be compressed by the target compression ratio using the one of the at least one lossless compression scheme, encoding the image data by the target compression ratio using one of at least one lossy compression scheme.

Abstract: An electronic device having a display and a sensor and methods for operating the same are provided. The electronic device includes a housing, a display disposed on a surface of the housing, a sensor mounted under the display inside the housing to detect light received through the display, and a processor electrically connected with the display and the sensor, wherein the processor is configured to determine an illuminance of an outside of the housing using detection data obtained by the sensor while the display displays an image and relevant information between the display and the sensor.
