Apparatus for acquiring image and electronic device including the same

An electronic device for acquiring images, the electronic device comprising:

• a multispectral sensor configured to sense light reflected from an object;
• an input unit configured to receive a user input;
• a display;
• a processor configured to generate and display an output image on the display based on a multispectral signal received from the multispectral sensor and an input signal received from the input unit;
• and
• a memory storing instructions that, when executed by the processor, cause the electronic device to:
• generate N channel images based on the multispectral signal obtained from a plurality of channels of the multispectral sensor, N being a positive integer greater than zero;
• select at least one first channel image corresponding to a visible wavelength band from among the N channel images;
• generate a reference image based on the at least one first channel image;
• select a second channel image from remaining channel images of the N channel images, the remaining channel images corresponding to remaining channels of the plurality of channels of the multispectral sensor distinct from first channels corresponding to the at least one first channel image;
• generate object information by analyzing the second channel image;
• and
• generate the output image by combining the reference image with the object information.
