Method for resizing image in wireless terminal and wireless terminal adapted for resizing
First Claim
1. A method for converting an image size in a wireless terminal, the method comprising the steps of:
- outputting two images from a camera module, whereby the two images are two interlaced fields of a television scanning scheme;
determining a size of the images output from the camera module;
extracting one image of the two images output from the camera module;
resizing the size of the extracted image to a size suitable for a display unit through at least two resizing steps when the size of the image output from the camera module differs from the size of the image to be output through the display unit; and
outputting the resized image,wherein resizing the extracted image comprises dividing columns of pixels of the image into a plurality of groups of columns based on a pattern of the columns, and removing one of the plurality of groups of columns.

Abstract
An apparatus and method for converting an image in a wireless terminal are disclosed. An apparatus and method for resizing an image output from a camera module such that the image has a size suitable for a display unit in a wireless terminal are provided. The method involves determining a size of an image output from a camera module, resizing the size of the image output from the camera module to a size suitable for a display unit when the size of the image output from the camera module differs from the size of the image to be output through the display unit, and outputting the resized image. The method involves determining a size of an image output from a camera module, and resizing a 720×480 image to a 320×240 image to be output through a display unit when the camera module has output the 720×480 image, and outputting the 320×240 image.

2. A method for converting an image size in a wireless terminal, the method comprising the steps of:
-
outputting two 720×
240 images from a camera module, whereby the two 720×
240 images are two interlaced fields of a television scanning scheme;determining a size of the images output from the camera module; extracting one 720×
240 image of the two 720×
240 images output from the camera module;resizing the extracted 720×
240 image to a 320×
240 image to be output through a display unit through at least two steps when the camera module has output the 720×
480 image; andoutputting the 320×
240 image,wherein resizing the extracted 720×
240 image comprises dividing columns of pixels of the image into a plurality of groups of columns based on a pattern of the columns, and removing one of the plurality of groups of columns.- View Dependent Claims (3, 4, 5, 6, 7, 8, 9)
second-resizing the 360×
240 image resized through a first-resizing step to a 320×
240 image.

4. The method as claimed in claim 3, wherein, in the first-resizing step, 720 pixels constituting a horizontal image of the 720×
- 240 image are reduced by half, whereby the 720×
240 image is resized to the 360×
240 image.
- 240 image are reduced by half, whereby the 720×

5. The method as claimed in claim 4, wherein one per two pixels is removed in the 720 pixels constituting the horizontal image, whereby the 720×
- 240 image is resized to the 360×
240 image.
- 240 image is resized to the 360×
-
6. The method as claimed in claim 4, wherein 360 pixels are randomly selected and removed from the 720 pixels constituting the horizontal image, whereby the 720×
- 240 image is resized to the 360×
240 image.
- 240 image is resized to the 360×
-
7. The method as claimed in claim 3, wherein, 40 pixels are removed from 360 pixels constituting a horizontal image of the 360×
- 240 image in a second resizing, thereby resizing the 360×
240 image to the 320×
240 image.
- 240 image in a second resizing, thereby resizing the 360×
-
8. The method as claimed in claim 7, wherein the 360 pixels constituting the horizontal image are divided into nine groups comprising 40 pixels in each group, and 40 pixels comprised in at least one of the nine groups are removed, thereby resizing the 360×
- 240 image to the 320×
240 image.
- 240 image to the 320×
-
9. The method as claimed in claim 7, wherein 40 pixels are randomly selected and removed from the 360 pixels constituting the horizontal image, thereby resizing the 360×
- 240 image to the 320×
240 image.
- 240 image to the 320×

10. A wireless terminal comprising:
-
a controller for determining a size of an image output from a camera module, whereby the camera module outputs two images as two interlaced fields of a television scanning scheme; an image processing unit for extracting one image of the two images output from the camera module, and for resizing the extracted image output to a size suitable for a display unit through at least two resizing steps when the size of the extracted image differs from the size of the image to be output through the display unit, wherein the image processing unit divides columns of pixels of the image into a plurality of groups of columns based on a pattern of the columns, and removes one of the plurality of groups of columns; and
a display unit for outputting the resized image.- View Dependent Claims (11, 12)
