| 20090238463 | METHOD FOR DETECTING IMAGE EDGE AND IMAGE INTERPOLATION USING THE SAME - A method for detecting an image edge is provided. Pixel data of neighbor lines of an image are read to generate a first and a second inclined edge areas between two neighbor lines. The incline edge areas are determined by detecting whether a difference of two corresponding pixel data exceeds a preset edge threshold. Then, whether there is an overlapped or nearby portion between the inclined edge areas is determined, so as to find an incline edge. | 09-24-2009 |
| 20090252438 | METHOD AND DEVICE FOR IMAGE INTERPOLATION CHARACTERISTIC PROCESSING DEVICE AND IMAGE INTERPOLATION DEVICE USING THE SAME - An image interpolation processing device is provided for interpolating at least one line between two adjacent lines. A prefetch unit is to prefetch pixel data of the two adjacent lines with a predetermined pixel length, so as to obtain a plurality of basic characteristics that are then stored in a first register. A characteristic processing unit is used for cutting and/or linking the basic characteristics to generate at least one set of linked characteristics. The linked characteristics are stored in a second register, as a reference for an operation unit to perform the interpolation. The operations between the operation unit and the prefetch unit are separated by a predetermined edge length. | 10-08-2009 |
| 20090257678 | IMAGE PROCESSING CIRCUIT AND METHOD THEREOF FOR ENHANCING TEXT DISPLAYING - An image processing circuit and method thereof for enhancing text displaying of an image are provided. The image processing circuit performs the method. Firstly, at least a first illumination area and at least a second illumination, which is located adjacent to the first illumination area in the image are defined according to luminance values of a plurality of pixels of the image. Next, a luminance regulation value of at least one of the pixels in the first illumination area is calculated, and the luminance value of the corresponding pixel in the first illumination area is adjusted according to the luminance regulation value. During processing of the image, the luminance values of all of the pixels in the second illumination area are restricted from any adjustment. | 10-15-2009 |

| 20100231489 | ORGANIC ELECTROLUMINESCENCE STRUCTURE HAVING A HEIGHT DIFFERENCE BETWEEN SURFACES OF A CONTROL DEVICE AND AN ORGANIC ELECTROLUMINESCENCE DEVICE - An organic electroluminescence structure comprises a first substrate, an organic electroluminescence device, and a control device. Forming either a lifting layer under the control device or a recess under the organic electroluminescence device, or forming both of them, creates a difference between their tops, in order to reduce the dark spots and promote the yield of the end product. The lifting layer preferably has a thickness greater than about 0.5 micro meters and the recess has a depth ranges of about 0.1 micro meters to about 100 micro meters. Alternatively, the height difference between the upper surfaces of the control device and the organic electroluminescence device is controlled to be greater than about 2 micro meters or substantially equal to 2 micro meters. | 09-16-2010 |
