Abstract

Methods and apparatuses for generating image data, and systems thereof determine position information of a transceiving device by using characteristics of an electric wave transmitted from the transceiving device; set a region of interest (ROI) in an image by using the determined position information of the transceiving device; and generate an output image.

First claim

The invention claimed is:

1. A method of operating an image capturing apparatus, the method comprising:
receiving, by a transceiver, a directional electric wave transmitted from an external device accompanied by an object;
obtaining, by an image sensor, a full frame image including an image of the object;
determining, by at least one processor, a direction of the object by using a direction from which the directional electric wave is received;
determining, by the at least one processor, a distance between the object and the image capturing apparatus by using an intensity of the received directional electric wave;
determining, by the at least one processor, a region of interest (ROI) as a portion of the full frame image, based on the determined direction and the determined distance, wherein the image of the object is included in the ROI; and
generating, by the at least one processor, image data by using the ROI.

2. The method of claim 1 , wherein the determining of the direction of the object comprises:
determining, by the at least one processor, the direction from which the directional electric wave is received with strongest intensity by using a beam forming method; and
determining, by the at least one processor, the direction of the object by using the determined direction from which the directional electric wave is received.

3. The method of claim 1 , wherein the determining of the ROI comprises:
determining, by the at least one processor, a position of the ROI in the full frame image by using the direction of the object.

4. The method of claim 1 , wherein the determining of the ROI comprises:
determining, by the at least one processor, a size of the ROI in the full frame image by using the distance between the object and the image capturing apparatus.

5. The method of claim 1 , wherein the generating of the image data by using the ROI comprises:
generating, by the at least one processor, image data of the full frame image; and
outputting, by the at least one processor, image data of an image portion corresponding to the ROI among the image data of the full frame image.

6. The method of claim 1 , wherein the generating of the image data by using the ROI comprises:
generating, by the at least one processor, image data of an image portion corresponding to the ROI in the full frame image; and
outputting, by the at least one processor, the generated image data.

7. The method of claim 1 , wherein the generating of the image data by using the ROI comprises:
generating, by the at least one processor, first image data of the full frame image with low resolution;
and
generating, by the at least one processor, second image data of an image portion corresponding to the ROI in the full frame image with high resolution.

8. The method of claim 1 , wherein the determining of the ROI comprises determining a position of the ROI according to a position of the image of the object in the full frame image.

9. A non-transitory computer-readable recording medium recorded with a program for performing a method of operating an image capturing apparatus, the method comprising:
receiving, by a transceiver, a directional electric wave transmitted from an external device accompanied by an object;
obtaining, by an image sensor, a full frame image including an image of the object;
determining, by at least one processor, a direction of the object by using a direction from which the directional electric wave is received;
determining, by the at least one processor, a distance between the object and the image capturing apparatus by using an intensity of the received directional electric wave;
determining, by the at least one processor, a region of interest (ROI) as a portion of the full frame image, based on the determined direction and the determined distance, wherein the image of the object is included in the ROI; and
generating, by the at least one processor, image data by using the ROI.

10. An apparatus for capturing an image, the apparatus comprising:
