Electronic device, and autofocus processing method in electronic device

A method for autofocus processing in an electronic device, the method comprising:

• receiving a first image obtained by photographing a subject at a first position of at least one lens when an autofocus search is implemented;
• performing image processing and autofocus processing on the first image;
• receiving a second image obtained by photographing the subject at a second position of the lens;
• generating compensation information using first brightness information on the first image and second brightness information on the second image;
• compensating for a brightness of the second image using the compensation information;
• and
• performing image processing and autofocus processing on the second image with the compensated brightness.

A non-transitory computer-readable recording medium configured to store a program that, when executed by a processor, cause the processor to perform:

• an operation of receiving a first image obtained by photographing a subject at a first position of at least one lens when an autofocus search is implemented;
• an operation of performing image processing and autofocus processing on the first image;
• an operation of receiving a second image obtained by photographing the subject at a second position of the lens;
• an operation of generating compensation information using first brightness information on the first image and second brightness information on the second image;
• an operation of compensating for a brightness of the second image using the compensation information;
• and
• an operation of performing image processing and autofocus processing on the second image with the compensated brightness.
