    摘要： A human face detection device includes a photosensitive element, a human face detection unit, and a skin color threshold generation unit. The photosensitive element is used for capturing a first image containing a first human face block. The human face detection unit compares the first image with at least one human face feature, so as to detect the first human face block. The skin color threshold generation unit is used for updating a skin color threshold value according to the detected first human face block. The skin color threshold value is used for filtering the first image signal to obtain a candidate region, the human face detection unit compares the candidate region with the at least one human face feature to obtain the first human face block, and the skin color threshold value determines whether the first human face block detected by the human face detection unit is correct.

    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： There is provided an interference removing method of an image system including the steps of: respectively acquiring different numbers of images within two brightness intervals having different brightness variations using an image sensor having a sampling frequency; lighting a light source with a lighting frequency, which is a half of the sampling frequency, and synchronizing to the sampling frequency; and subtracting a first image, which is associated with the lighting of the light source, acquired in a later brightness interval of two adjacent brightness intervals having identical brightness variations by a second image, which is associated with a sampling time of the first image, acquired in an earlier brightness interval of the two adjacent brightness intervals. The present disclosure further provides an image system.
