摘要： There is provided an image system including at least one image sensor, a light source and a processing unit. The at least one image sensor sequentially acquires at least two images within each of the brightness variation intervals of an ambient light source. The light source lights once within each of the brightness variation intervals and the lighting of the light source is synchronized to one of the images acquired by the at least one image sensor. The processing unit calculates an image difference between the image synchronizing to the lighting of the light source and the image not synchronizing to the lighting of the light source thereby eliminating interference from the ambient light source. There is further provided a denoising method for an image system.

摘要： A shooting parameter adjustment method for face detection includes (A) acquiring an image; (B) dividing the image into a plurality of blocks, and calculating a brightness value of each of the blocks; (C) selecting at least one of the plurality of blocks, and adjusting a shooting parameter according to the brightness value of the selected block; and (D) acquiring another image according to the shooting parameter, and performing a face detection procedure with the another image. The shooting parameter adjustment method can automatically adjust a shooting parameter of an image capturing device according to brightness of different blocks in an image. Therefore, by using this method, the brightness of a face, no matter being too high or too low, can be adjusted to a value suitable for face detection, so as to improve the accuracy of the face detection procedure.
