Abstract

An electronic device for image processing and a method thereof are provided. The electronic device includes a lens part, an image sensor, a memory, and at least one image processor. The at least one image processor for processing an image signal of the image sensor is configured to collect first image data through the image sensor at a first time, collect first recognition information about a plurality of objects recognized from the first image data, collect second image data through the image sensor at a second time, collect second recognition information about an object recognized from the second image data, and determine an object of interest of a user based on a difference between the first recognition information and the second recognition information.

First claim

What is claimed is:

1 . An electronic device comprising:
a lens part configured to collect light from outside of the electronic device; an image sensor configured to change light passing through the lens part to an electrical signal; a memory; and at least one image processor for processing an image signal of the image sensor configured to:
collect first image data through the image sensor at a first time,
collect first recognition information about a plurality of objects recognized from the first image data,
collect second image data through the image sensor at a second time,
collect second recognition information about an object recognized from the second image data, and
determine an object of interest of a user based on a difference between the first recognition information and the second recognition information.

2 . The electronic device of claim 1 , wherein the at least one image processor is further configured to:
generate a control signal for controlling the lens part or the image sensor, by using the determined object of interest.

3 . The electronic device of claim 2 , wherein the at least one image processor is further configured to:
perform at least one of auto focus (AF), auto exposure (AE), auto white balance (AWB), or color correction by using the control signal.

4 . The electronic device of claim 1 ,
wherein the memory stores priority information about an external object, and wherein the at least one image processor is further configured to:
determine the object of interest before the second time, based on the first recognition information or the priority information, and
determine the object of interest after the second time, based on the difference between the first recognition information and the second recognition information.

5 . The electronic device of claim 1 , wherein, if a capture input associated with a still image occurs, the at least one image processor is further configured to:
update priority information based on the first recognition information and the second recognition information.

6 . The electronic device of claim 5 , wherein the at least one image processor is further configured to:
update the priority information about an object recognized from an image stored in response to the capture input.

7 . The electronic device of claim 5 , further comprising:
a transceiver,
wherein the at least one image processor is further configured to transmit the updated priority information to an external device by using the transceiver.

8 . The electronic device of claim 1 , wherein, if a capture end input or a storage input associated with a video occurs, the at least one image processor is further configured to:
update priority information based on the first recognition information and the second recognition information.

9 . The electronic device of claim 8 , wherein the at least one image processor is further configured to:
update the priority information about an object recognized from the video stored in response to the capture end input or the storage input.

10 . The electronic device of claim 1 , further comprising:
at least one sensor configured to obtain information associated with the electronic device or a situation of a periphery of the electronic device.

11 . The electronic device of claim 10 , wherein the at least one image processor is further configured to:
determine whether the electronic device moves by a specified range or more or the electronic device rotates by the specified range or more, through the at least one sensor.

12 . The electronic device of claim 10 , wherein the at least one image processor is further configured to:
compare the first image with the second image to extract movement information of an object, extract movement information of the electronic device through the at least one sensor, and if the movement information of the object is synchronized with the movement information of the electronic device, set a priority of the object to be high.

13 . The electronic device of claim 10 , wherein, if movement of the electronic device that is not less than a specified range is sensed through the at least one sensor between the first time and the second time, the at least one image processor is further configured to:
determine the object of interest of the user based on the difference between the first recognition information and the second recognition information.

14 . The electronic device of claim 4 , wherein the priority information includes at least part of the priority information, a capture frequency, composition information, information about a capture date, or capture location information of the object.

15 . The electronic device of claim 4 , wherein the at least one image processor is further configured to:
update the priority information based on search information of the user.

16 . The electronic device of claim 1 , wherein the at least one image processor is further configured to:
continuously receive an image signal through the image sensor between the first time and the second time.

17 . The electronic device of claim 1 , further comprising:
a display configured to output contents, wherein the at least one image processor is further configured to:
display information associated with a priority of an object included in an image output through the display, at a third time after the second time.

18 . A method for image processing performed in an electronic device, the method comprising:
collecting a first image through an image sensor at a first time; collecting first recognition information about a plurality of objects recognized from the first image; collecting a second image through the image sensor at a second time; collecting second recognition information about an object recognized from the second image; and determining an object of interest of a user based on a difference between the first recognition information and the second recognition information.

19 . The method of claim 18 , further comprising:
generating a control signal for controlling a lens part or the image sensor, by using the determined object of interest.

20 . The method of claim 18 , further comprising:
if a capture input associated with a still image is generated, updating priority information about an external object stored in a memory based on the first recognition information and the second recognition information; and if a capture end input or a storage input associated with a video is generated, updating priority information about an external object stored in a memory based on the first recognition information and the second recognition information.
