Image processing device and operational method thereof

A method of image processing by an image processing device that includes an image sensor module and a processor, the method comprising:

• obtaining, using the image sensor module, which includes a lens and an image sensor, a first image having first color information, the first image corresponding to an external object;
• moving at least one of the lens and the image sensor based on a designated pixel unit;
• obtaining, using the image sensor module with the moved at least one of the lens and the image sensor, a second image having second color information, the second image corresponding to the external object;
• and
• generating, by using the processor, a third image having third color information based on at least the first color information and the second color information, the third image corresponding to the external object,
• wherein obtaining the second image comprises:
• obtaining brightness information by using the image sensor;
• and
• obtaining the second image based on the sensed brightness information.

A non-transitory computer readable recording medium that records a program for implementing operations in an image processing device including an image sensor module and a processor, the operations comprising:

• obtaining, using the image sensor module, which includes a lens and an image sensor, a first image having first color information, the first image corresponding to an external object;
• moving at least one of the lens and the image sensor based on a designated pixel unit;
• obtaining, using the image sensor module with the moved at least one of the lens and the image sensor, a second image having second color information, the second image corresponding to the external object;
• generating, by using the processor, a third image having third color information based on at least the first color information and the second color information, the third image corresponding to the external object,
• wherein obtaining the second image comprises:
• obtaining brightness information by using the image sensor;
• and
• obtaining the second image based on the sensed brightness information.
