Abstract
A correction method for ill-exposed (IE) images, comprises the following steps. (1) A series of original images are captured. (2) The original images are classified as a set of first well-exposed (WE) images and IE images by utilizing a first computational model, according to a lightness distribution of each of the original images. The IE images have a plurality of exposure types including a back-lit (BL) type, an over-exposed (OE) type, and an under-exposed (UE) type. (3) The IE images are corrected to obtain a set of second WE images by utilizing a second computational model. A plurality of perceptual parameters and structural parameters of each of the IE images are extracted and then adjusted according to the BL, OE, and UE types respectively. (4) The first WE images and the second WE images are provided as a set of output images.
