The input unit is used for receiving an image data, and obtaining a plurality of color signal values for forming the image data. The first multiplier is used for multiplying the color signals by a transfer matrix to obtain a plurality of transfer color signal values, so as to form a display image. | 10-15-2009 |
| 20100034475 | IMAGE COMPRESSION/DECOMPRESSION DEVICE AND METHOD THEREOF - An image compression/decompression device and a method thereof are provided. In the method, a first array is generated according to an input image array, and further, a second array is generated by performing an edge detection algorithm according to the input image array. Besides, a plurality of elements of a third array is generated according to the first array. Furthermore, a group of elements of the third array is selected according to the second array. In addition, an average value of the group of elements is computed to obtain an element of an output image array. Each element of the input image array and the third array is M bits, and each element of the first array is N bits, wherein M and N are natural numbers, and M is larger than N. Thereby, the quality of a decompressed image is improved. | 02-11-2010 |
| 20100061646 | IMAGE PROCESSING METHOD - An image processing method is provided. The image processing method includes obtaining a least significant bit (LSB) associated with a pixel block. Further, two bits are reduced from a bit number of each of the pixels of the pixel block. Thereafter whether to carry the pixel or not is determined according to the LSB. When the LSB is 01 or 11, the carry manners of each pixel of the pixel block in two consecutive frames are asymmetric one to another. Further, under the conditions of when the LSB is 01 and 11, respectively, the carry manners of the pixels of the pixel block mutually compensate. Therefore, the display performance of a display is improved. | 03-11-2010 |
| 20100085386 | DRIVING CRICUIT AND GRAY INSERTION METHOD OF LIQUID CRYSTAL DISPLAY - A driving circuit and a gray insertion method of a liquid crystal display (LCD) are provided. The gray insertion method includes analyzing whether a current frame belongs to a dynamic frame or a static frame. When the current frame belongs to a dynamic frame, charging time of a gray insertion image is extended. When the current frame belongs to a static frame, the charging time of a gray insertion image is shortened. As a result, motion blur on the LCD can be reduced and image quality can be increased. | 04-08-2010 |
| 20100265280 | DRIVING CIRCUIT AND GRAY INSERTION METHOD OF LIQUID CRYSTAL DISPLAY - A driving circuit and a gray insertion method of a liquid crystal display (LCD) are described. In the gray insertion method, whether a dynamic frame or a static frame display by the LCD is determined. When the LCD displays the dynamic frame, a gray insertion level of a frame of the display and a duty cycle of a pulse width module (PWM) signal are increased synchronously, wherein the PWM signal drives a back light module of the display. When the LCD displays the static frame, the gray insertion level of a frame of the display and the duty cycle of the PWM signal are decreased synchronously. As a result, a motion blur on LCD is reduced and luminance of a display frame is maintained. | 10-21-2010 |
| 20100289814 | COLOR TRANSFORMATION METHOD AND CORRESPONDING COLOR DISPLAY METHOD - A color transformation method includes following steps. First, a color signal is received. Then, a saturation calculation step is performed to generate a saturation value of the color signal, and a hue-angle-weighting calculation step is performed to generate a first hue-angle weighting of the color signal corresponding to a first LUT and a second hue-angle weighting of the color signal corresponding to a second LUT. Next, a color calculation step is performed to transform the color signal into a first color output signal according to the saturation value and the first hue-angle weighting and to transform the color signal to a second color output signal according to the saturation value and the second hue-angle weighting. | 11-18-2010 |
| 20100302234 | METHOD OF ESTABLISHING DOF DATA OF 3D IMAGE AND SYSTEM THEREOF - A method and a system of establishing depth of field data of a 3D image, applicable to a 3D image including a first and a second visual image. The system includes a storage module, an offset calculator, and a comparator. An offset vector matrix includes data fields in the same number as that of pixels of a first visual image. An offset calculator divides a reference frame by taking an a | 12-02-2010 |
| 20100322535 | IMAGE TRANSFORMATION METHOD ADAPTED TO COMPUTER PROGRAM PRODUCT AND IMAGE DISPLAY DEVICE - An image transformation method for use in a computer program product and an image display device is provided. In the image transformation method, a two dimensional image and a corresponding depth image are acquired first. A motion process is performed on the two dimensional image to obtain a plurality of motion images according to the depth image and a plurality of gain values. Then, a plurality of view images are provided and an interpolation process is performed on each motion image to obtain the corresponding view image. Finally, a synthesis process is performed on the view images to obtain a three dimensional image. | 12-23-2010 |
