Abstract

An optical detecting device includes an image capturing device and a processor. The processor is coupled to a light source and an image capturing device. The processor is configured to adjust a light intensity of the light source for irradiating a correction object in order that a gray value of at least one image block, captured by the image capturing device, of the correction object matches a target correction value, and record a target light intensity while the target light intensity matches the target correction value; control the light source to irradiate light on a testing object with the target light intensity, and control the image capturing device to capture a testing object image of the testing object; and calculate ratios of a target gray value to the gray value of a plurality of pixels of the testing object image to obtain a mapping table.
