The invention discloses a method of achieving fast driving of an area array charge coupled device (CCD) by means of inductive charge accumulation. The method comprises the steps that model parameter setting is carried out according to imaging requirements; an area array CCD driving schedule is generated; the area array CCD enters into an integration phase and inductive charges are generated; the integration phase ends and the inductive charges are transferred to a storage area; the area array CCD enters into the next integration phase; the inductive charges are transferred to a horizontal shifting register; the inductive charge accumulation is carried out by repeating the previous operation according to a given parameter; the horizontal shifting register outputs a line of inductive charges; the previous operation is repeated according to the given parameter until inductive charges of one frame of images are all output; and output of the next frame of images is carried out by repeating the fourth step to the ninth step. According to the method of achieving the fast driving of the area array CCD by means of the inductive charge accumulation, fast output of inductive charges of the area array CCD is achieved by means of the model parameter setting under the circumstance that external imaging environment changes, and the light adaptation range of the area array CCD can be widened greatly.

The invention discloses a light adaptation human skin colour detection method in the model identification and image processing technical field. The method disclosed in the invention comprises the following steps of: collecting a training database; using the training database to train a basal skin colour model and a light model; using the basal skin colour model to screen pixels of an image to be detected; finding out a light model closest to the image to be detected from the light model; using the model to correct the image to be detected and the basal skin colour model; and outputting the corrected image to be detected after being detected by the basal skin colour model. By means of the invention, the light component in a skin colour region in the image to be detected is obviously improved; the detection precision is improved; the accuracy of the skin colour detection is improved; and the noise interference is reduced.

A method of compensating an image based on light adaptation, a display device using the method, and an electronic device are disclosed. In one aspect, the method includes the steps of: determining a degree of light adaptation based on the amount of long-wavelength light in the lighting environment at which the image is displayed; The image data used to realize the image is converted via the CIE-XYZ color space into image data expressed in the CIE Long-Medium-Short (LMS) color space; the degree of light adaptation is applied to the converted image data expressed in the CIE-LMS color space, to generate compensated image data; and converting the compensated image data expressed in the CIE-LMS color space into image data to be displayed in the CIE-RGB color space via the CIE-XYZ color space.
