Filed: 2003-03-28
Granted: 2005-01-01
Abstract: The present invention relates to a method for automatically detecting the region of interest (ROI) in the image. In the method for automatically detecting ROI in the image, by conferring the coefficient after conversion of the image in the compression process, the incorporation of the variations of position and frequency of the coefficient block, and the compression bit rate requirement, detection is automatically conducted to generate the ROI of an image-related content variation. The bit flow of the related application is encoded for the different compressing process selections of the specified region based on each compressed standard so as to raise the vision quality of the ROI image after the decompression. In addition, the coefficient data after analysis and conversion is proposed, and is sorted into a small unit block so as to locate the center point of the interested small unit block assembly and use image processing skill to generate a continuous and closed mask for the ROI. The present invention is capable of having more adaptable characteristic for the requirement of the image content and the compressed bit rate. In addition, because the generation mechanism of the ROI mask is embedded in the compression procedure, the present invention also has the characteristic of low calculation cost.

Title: Reflector and liquid crystal display device
Inventor: NAGAYAMA KOHEI
IPC: G02B5/02
Filed: 2003-05-08
Granted: 2004-06-21
Abstract: The present invention provides a liquid crystal display device which reduces coloring caused by interference and provides ideal reflection characteristics and has a satisfactory display quality. Projecting patterns 20 of reflective pixel electrode 20 are so arranged in parallel respectively in a skew state of rotating an angle of 60 DEG formed in grid translation vectors of central hexagonal grids. The grid translation vectors are distributed uniformly in all directions. Since two-dimensional periodicity of arrangement of projecting patterns 20 is reduced as the whole, coloring caused by interference is suppressed. Since intervals of projecting patterns 20 can be made fixed, an ideal tilt angle distribution is obtained by matching a maximum interval of an interval distribution of projection patterns 20 to an interval of projecting patterns which gives the most suitable tilt angle distribution.
