Abstract

Disclosed is an electronic device including a memory that stores at least one command associated with an image encoding and a processor electrically connected to the memory. The command executed while the processor is operated divides a content generation buffer allocated in association with a specified content generation into a plurality of partial areas, stitches a previous image and a present image with respect to at least a portion of an area in which the present image overlaps with the previous image, and performs a parallel encoding on each of the partial areas of the stitched images in a specified block size when the stitched images are stored in the content generation buffer.

First claim

1 . An electronic device comprising:
a memory configured to store at least one command associated with an image encoding; and a processor configured to be electrically connected to the memory, wherein the command executed while the processor is operated is configured to:
divide a content generation buffer allocated in association with a specified content generation into a plurality of partial areas;
stitch a previous image and a present image with respect to at least a portion of an area in which a received present image overlaps with the previous image; and
perform a parallel encoding on each of the partial areas of the stitched images in a specified block size when the stitched images are stored in the content generation buffer.

2 . The electronic device of claim 1 , wherein the command executed while the processor is operated is configured to:
determine an image acquiring direction associated with the content generation based on a variation in movement of received preview images; or determine the image acquiring direction associated with the content generation using at least one sensor.

3 . The electronic device of claim 2 , wherein the command executed while the processor is operated is configured to allocate a content generation buffer having a different size depending on a shooting direction.

4 . The electronic device of claim 2 , wherein the command executed while the processor is operated is configured to:
allocate a content generation buffer having a first length in a first direction and a second length in a second direction with respect to a first shooting direction, or allocate a content generation buffer having a third length smaller than the first length in the first direction and the second length in the second direction with respect to a second shooting direction.

5 . The electronic device of claim 1 , wherein the command executed while the processor is operated is configured to:
output an image, which is to be acquired, to a background area of a display; and output the stitched images to the background area to be overlaid.

6 . The electronic device of claim 1 , wherein the command executed while the processor is operated is configured to output a preview area having a ratio corresponding to an entire size of the content generation buffer to a display during a image collection or after the image collection.

7 . The electronic device of claim 6 , wherein the command executed while the processor is operated is configured to output the preview area including a stitching area corresponding to the stitched images and a remaining area corresponding to the entire size of the content generation buffer.

8 . The electronic device of claim 1 , wherein the command executed while the processor is operated is configured to, when the image collection for the stitching is ended:
dispose a specified identifier, which indicates that a last block of the partial area is not used for processing a first block of another partial area, in the last block of each of the partial areas; dispose an end identifier, which indicates a last block of a last partial area of the content, in an area adjacent to the last block of the last partial area of the content; and dispose header information corresponding to an entire content area in front of a first partial area.

9 . The electronic device of claim 1 , wherein the command executed while the processor is operated is configured to select and stitch an image, in which a similar area with respect to the pervious image is within a certain range, among received images.

10 . The electronic device of claim 1 , wherein the command executed while the processor is operated is configured to exclude an area of the present image having a height different from the previous image from a buffering of the content generation buffer when the image is stitched.

11 . An image processing method by a processor of an electronic device, the method comprising:
dividing a content generation buffer allocated in association with a specified content generation into a plurality of partial areas; stitching a previous image and a present image with respect to an area in which a received present image overlaps with the previous image to store the stitched images in the content generation buffer; and performing a parallel encoding on each of the partial areas of the stitched images in a specified block size when the stitched images are stored in the content generation buffer.

12 . The method of claim 11 , further comprising at least one of determining an image acquiring direction associated with the content generation based on a variation in movement of received preview images or determining the image acquiring direction associated with the content generation using at least one sensor.

13 . The method of claim 12 , further comprising allocating a content generation buffer having a different size depending on the shooting direction.

14 . The method of claim 13 , wherein the allocating of the content generation buffer includes:
allocating a content generation buffer having a first length in a first direction and a second length in a second direction with respect to a first shooting direction; and allocating a content generation buffer having a third length smaller than the first length in the first direction and the second length in the second direction with respect to a second shooting direction.

15 . The method of claim 11 , further comprising:
outputting an image, which is to be acquired, to a background area of a display; and outputting the stitched images to the background area to be overlaid.

16 . The method of claim 11 , further comprising outputting a preview area having a ratio corresponding to an entire size of the content generation buffer to a display during a image collection or after the image collection.

17 . The method of claim 16 , wherein the outputting includes outputting the preview area including a stitching area corresponding to the stitched images and a remaining area corresponding to the entire size of the content generation buffer.

18 . The method of claim 11 , further comprising, when the image collection for the stitching is ended:
disposing a specified identifier, which indicates that a last block of the partial area is not used for processing a first block of another partial area, in the last block of each of the partial areas; disposing an end identifier, which indicates a last block of a last partial area of the content, in an area adjacent to the last block of the last partial area of the content; and disposing header information corresponding to an entire content area in front of a first partial area.

19 . The method of claim 11 , wherein the stitching includes selecting and stitching an image, in which a similar area with respect to the pervious image is within a certain range, among received images.

20 . The method of claim 11 , further comprising excluding an area of the present image having a height different from the previous image from a buffering of the content generation buffer when the image is stitched.
