Abstract
A computer readable recording media, having at least one program code recorded thereon, an image adjusting method can be performed when the program code is read and executed. The image adjusting method comprises: catching a current image; computing at least one kind of brightness information of the current image; respectively setting corresponding threshold values to different kinds of the brightness information; and determining if a contrast enhancing operation should be performed to the current image to generate an adjusted image according to a number that the brightness information is over the threshold value.
