Claim Text:
1. A non-transitory computer readable recording medium, having at least one program code recorded thereon, an image adjusting method can be performed when the program code is read and executed, wherein the image adjusting method is applied to an optical navigating apparatus comprising an image sensor and a displacement detecting module, wherein the image adjusting method comprises: (a) catching a current image via the image sensor; (b) computing at least one kind of brightness information of the current image via the displacement detecting module; (c) respectively setting corresponding threshold values to different kinds of the brightness information via the displacement detecting module; and (d) 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 via the displacement detecting module, and determining a ratio for the contrast enhancing operation according to the number that the brightness information is over the threshold value via the displacement detecting module.
