Method of encoding and decoding pictured data for enhancing image resolution
First Claim
1. 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.

Abstract
The present invention is a method for enhancing image resolution. A high-resolution image is decomposed into plural primary image data with DVD/SVCD/VCD standard image resolution and then these plural primary image data are stored in plural user data format or secondary viewing angle data format of DVD/VCD/SVCD image data carrier. Next, the average value of pixels at the same positions of the plural primary image data is calculated and secondary image data are formed. Finally, the secondary image data are stored in a video-audio data format or a primary viewing angle data format of DVD/VCD/SVCD image data carrier. In order to play the high-resolution image data carrier, the plural primary image data is combined and restored to form a high-resolution image, hence achieving the goal of enhancing the image resolution of DVD/SVCD/VCD.

9. A method for enhancing the image resolution, wherein the method is applied to a high-resolution image data carrier for storing or playing a high-resolution image that is at least twice the standard resolution, the method comprising the following steps:
-
setting the high-resolution image data carrier to have a video-audio data format and plural user data format; decomposing the high-resolution image into plural primary image data of standard image resolution; storing the plural primary image data into the user data format; calculating an average of the pixels at the same positions in the plural primary image data for forming a secondary image data; encoding the secondary image data to form a disc playable image data; storing the secondary image data into the video-audio data format of the high-resolution image data carrier; playing back the secondary image data from the video-audio data format by any playback apparatus if standard resolution is required; and combining and restoring secondary image data from the video-audio data formats and another primary image data from the user data formats to form the high-resolution image and playable 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 secondary image data and the primary image data at a same position of the user data format to combine and restore the high-resolution image. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. An apparatus for encoding picture data to enhance image resolution and storing the high-resolution image at least twice the standard image resolution to a image data carrier, the encoding apparatus comprising at least:
-
an image-decomposing unit, for reading out the high-resolution image and decomposing the high-resolution image into plural primary image data of standard image resolution; an image operation unit, for calculating an average value of pixels at the same position from plural primary image data for forming secondary image data; an image-encoding unit utilizing an image compression technique to encode the primary and secondary image data and form a playable image data; an image storage unit, separately storing the plural primary image data into plural user data format of the image data carrier; and
storing the secondary image data in a video-audio data format of the image data carrier;an image-combining unit for acquiring the secondary image data from the video-audio data format and the primary image data from the user data format to form a combined playable image data; and a playing unit for playing back one set of the primary image data from the video-audio data format if low resolution is required and playing back the combined playable image data if high resolution is required. - View Dependent Claims (18, 19, 20)
