Patent ID: 7463816

Claim:
A method for enhancing image resolution, wherein the method is applied to a high-resolution image data carrier for storing or playing a high-resolution image at least twice the standard image resolution, the method comprising the following steps: defining a video-audio data format and a plurality of user data formats on the high-resolution image data carrier; evenly decomposing and distributing the plural image pixels of the high-resolution image, adjacent along a vertical direction or a horizontal screen on a screen, into corresponding plural pixels of primary image data of standard image resolution, wherein the corresponding plural pixels are located at a same pixel position; encoding at least one primary image data to form a disc playable image data; storing one set of the primary image data into the video-audio data format of the high-resolution image data carrier and storing another primary image data set separately into the plural of user data formats; playing back one set of the primary image data from the video-audio data format by any playback apparatus if low resolution is required; and combining one set of the primary image data from the video-audio data format and another primary image data from the user data formats to form a combined playable image data and playing back the combined playable image data by a specific playback apparatus if high resolution is required; wherein the specific playback apparatus comprises: a readout unit for reading out the plural user data formats on the high-resolution image data carrier; and an image-combining unit for acquiring the primary image data at a same position of the user data format to combine and restore the high-resolution image.
