摘要： A calibrating method of calibrating a measured distance of a measured object measured by a distance-measuring device according to an ambient temperature includes providing a temperature sensor for measuring the ambient temperature of the distance-measuring device, calculating a calibrated imaging location of the measured object according to the ambient temperature and an imaging location of the measured object, and calibrating the measured distance according to the calibrated imaging location. In this way, when the distance-measuring device measures the measured object, the error due to the variation of the ambient temperature is avoided according to the calibrating method.

摘要： A dynamic image compression method for human face detection includes the following steps. An original image is acquired. The image is divided into a plurality of blocks. A first brightness and a plurality of gradient values of each block are calculated. A second brightness of each block is calculated according to a brightness transformation function and the first brightness. A reconstruction image is generated according to the second brightness and the plurality of gradient values of each block. Human face detection is performed according to the reconstruction image. Therefore, gradient values within an original square are. When the human face detection process is performed through gradient direction information, a success rate of detection is greatly increased.

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.
