Electronic device for providing function by using RGB image and IR image acquired through one image sensor

An electronic device comprising:

• an image sensor including a color filter array, the color filter array including a first region transmitting visible light and infrared light and a second region transmitting infrared light;
• a memory;
• and
• a processor electrically connected to the image sensor and the memory,
• wherein the processor is configured to:
• execute an application,
• obtain first raw image data using a first image data set corresponding to the first region among raw image data obtained through the image sensor in response to a request to obtain a red-green-blue (RGB) image from the application, and provide the RGB image generated based at least on the obtained first raw image data to the application, and
• obtain second raw image data using a second image data set corresponding to the second region among raw image data obtained through the image sensor in response to a request to obtain an infrared (IR) image from the application, and provide the IR image generated based at least on the obtained second raw image data to the application,
• wherein the processor is further configured to
• obtain the first raw image data using the first image data set according to an illuminance corresponding to the raw image data falling within a first range, and
• obtain the first raw image data using at least a part of the raw image data in which a component corresponding to infrared light included in the raw image data is corrected in the first image data set based at least on the second image data set, according to the illuminance corresponding to the raw image data falling within a second range including a range which is higher than the first range, and
• wherein the RGB image obtained according to the illuminance corresponding to the raw image data falling within the first range includes an infrared component, and the RGB image obtained according to the illuminance corresponding to the raw image data falling within the second range does not include the infrared component.
