Patent number: 7982752Abstract: An image display apparatus and method are disclosed. In the present invention, image frames of various data information sizes are displayed with a selected output data information size. If the selected output data information size is below a limit of a storage medium for buffering image frames to be displayed, the data information size of an input image frame is adjusted to the output data information, and the image frame is displayed in the output data information size. If the output data information exceeds the limit of the storage medium, the input image is over-compressed to have a lower data information size. Then an image processing is performed to the image frame, so that the processed image frame is decompressed to have the output data information size before being displayed. Therefore, the decompressed image frame can be displayed in the selected output data information size.Type: GrantFiled: July 28, 2008Date of Patent: July 19, 2011Assignee: Mediatek Inc.Inventors: Chi-chin Lien, Ting-hsun Wei, Hui-cheng Hsu

The buffer is capable of storing scaling reference lines retrieved from the video source. The scaler is used for generating scaled lines based on the scaling reference lines stored in the buffer, wherein the scaled lines are used in the video stream supplied to the display apparatus, and an input line period length of the scaler receiving the video source and an output line period length of the scaler supplying the video stream to the display apparatus are the same. Valid scaled lines generated for each frame by the scaler is less than a total number of output line periods for each frame of the video stream.Type: ApplicationFiled: January 12, 2009Publication date: July 15, 2010Inventors: Te-Wei Chen, Chi-Chin Lien, Hui-Cheng Hsu
