1. An electronic device comprising:
a first housing;
a second housing configured to be movable with respect to the first housing;
a flexible display coupled to the first housing or the second housing;
an illuminance sensor disposed under the flexible display;
at least one processor comprising processing circuitry, and
memory storing instructions that, when executed by the at least one processor, cause the electronic device to:
measure an illuminance value corresponding to a time at which the flexible display is off, using the illuminance sensor,
determine a movement speed of the flexible display,
determine an area of interest of the illuminance sensor based on the determined movement speed of the flexible display,
obtain color information of multiple images displayed in the area of interest,
calculate, based on determining that the movement speed of the flexible display is constant, a correction value using an average value of color information obtained from the multiple images,
assign, based on determining that the movement speed of the flexible display is not constant, a weight value to color information obtained from multiple images and calculate the correction value using the color information to which the weight value is assigned, the weight value being determined based on the movement speed of the flexible display,
correct the measured illuminance value based on the calculated correction value, and
adjust luminance of the flexible display using the corrected illuminance value.
