Method and apparatus for processing continuous image data captured by digital image processor
View Patent ↗Provided are a method and apparatus for processing continuous image data captured by a digital image processor which encodes/decodes a plurality of continuous images in a Moving Picture Expert Group (MPEG) format. The apparatus includes a digital signal processing unit which compresses the continuous image data into video data in consideration of correlations between neighboring images, or converts the compressed video data into displayable data.
1. An apparatus for processing continuous image data captured by a digital image processor, comprising:
a digital signal processing unit
configured to compress the continuous image data using correlations between neighboring images,
configured to compress screennail images of the continuous image data independently of the correlations and include the independently compressed screennail images in the compressed continuous image data using the correlations, and
configured to convert the compressed continuous image data into displayable data.
2. The apparatus of claim 1 , wherein the digital signal processing unit comprises:
a data converter configured to convert the continuous image data into YCrCb (YCC) data;
a Moving Picture Expert Group (MPEG) encoder configured to compress the YCC data into MPEG data using correlations between neighboring images;
an MPEG decoder configured to decode the compressed MPEG data; and
a video driver configured to process the decoded data into a displayable signal.
3. The apparatus of claim 2 , wherein the video driver is configured to display a plurality of frames of the continuous image data as a still image.
4. The apparatus of claim 3 , wherein the apparatus is further configured to pseudo delete an image in response to a user selecting delete of a frame when the continuous image data is displayed, wherein pseudo delete is performed such that delete is only marked on a header of the selected frame and the selected frame is not actually deleted.
5. The apparatus of claim 2 , wherein the digital signal processing unit further comprises:
a Joint Photographic Experts Group (JPEG) encoder configured to convert the compressed MPEG data into YCC data and to compress the YCC data into JPEG data.
6. A method of processing continuous image data captured by a digital image processor, the method comprising:
compressing the continuous image data using correlations between neighboring images;
compressing screennail images of the continuous image data independently of the correlations and including the independently compressed screennail images in the compressed continuous image data using the correlations; and
converting the compressed continuous image data into displayable data.
7. The method of claim 6 , wherein the compressing of the continuous image data comprises:
converting the continuous image data into YCrCb (YCC) data; and
compressing the YCC data into Moving Picture Expert Group (MPEG) data using correlations between neighboring images.
8. The method of claim 6 , wherein the converting of the compressed continuous image data comprises:
decoding the compressed MPEG data; and
processing the decoded data into a displayable signal.
9. The method of claim 6 , wherein a plurality of frames of the continuous image data is displayed as a still image.
10. The method of claim 9 , further comprising, responsive to a delete request of a frame from a user, performing a pseudo delete such that delete is only marked on a header of the frame and the frame is not actually deleted.
11. The method of claim 8 , further comprising converting the compressed MPEG data into YCC data and compressing the YCC data into Joint Photographic Experts Group (JPEG) data.
