  • Patent number: 8891867
    Abstract: An image processing method is provided and includes the following steps. A source image arranged in a Bayer pattern is captured. A first-order image process is performed on the source image to produce a first image in YCbCr format. A second-order image process is performed on the source image to produce a second image in YCbCr format. Then, a noise-reducing process is performed on the first image in YCbCr format to produce a noise-reduced image. A blending operation is performed on luminance image of the noise-reduced image and luminance image of the second image in YCbCr format, and thereafter a chrominance image is combined with the blended image to produce a processed image. A noise reducing degree of the noise-reduced image is higher than that of the second image in YCbCr format.

    Abstract: A method for adjusting head mounted display adaptively and a head mounted display are provided. The method includes the following steps. Eye state parameters of a user wearing the head-mounted display are sensed by using a first sensing unit, and whether the user's eyes are discomfort or not is determined according to the eye state parameters. If yes, environmental parameters of the user's location are sensed by using a second sensing unit. The eyes state parameters and the environmental parameters are analyzed synthetically, such that the projection display setting of the head-mounted display could be adjusted adaptively.

  • Patent number: 8786729
    Abstract: An entered image is divided into a plurality of windows and it is determined, on a per-window basis, whether the image data within an applicable window is indicative of the color white, based upon the position of each window in the image and the continuity to its surrounding divided windows. A white balance method is performed based upon data of a window determined to be indicative of the color white. The present invention conducts a white balance process through the addition of determining the light source type weight and calculating the continuity of each divided window and its surrounding divided windows. In order the white balance process to accurately obtain the colors of an entered image even under the conditions of specific scenes with distinctive colors.
