ELECTRONIC DEVICE AND METHOD FOR INCREASING EXPOSURE CONTROL PERFORMANCE OF A CAMERA BY ADJUSTING EXPOSURE PARAMETER OF THE CAMERA

An electronic device and a method of controlling the electronic device are provided. The electronic device includes a camera configured to generate a detection signal by photoelectrically converting incident light, and one or more processors configured to control operations of the camera and process the detection signal, wherein the one or more processors are further configured to generate a plurality of input images from the detection signal, determine a first parameter applied to the camera, based on brightness information of each of the plurality of input images, detect at least one feature from each of the plurality of input images, determine whether to update the first parameter, based on a result of detecting the at least one feature, and adjust the first parameter, based on a brightness of the at least one feature upon determining to update the first parameter.
