System and method for detecting light sources in a multi-illuminated environment using a composite RGB-IR sensor

An electronic device for detecting light sources in a multi-illuminated environment, the electronic device comprises:

• a composite red-green-blue-infrared (RGB-IR) sensor configured to obtain an image;
• and
• at least one processor configured to:
• detect a multi-illuminant area using a visible raw image and a near-infrared (NIR) raw image of the image obtained using a composite RGB-IR sensor;
• divide each of the visible raw image and the NIR raw image into a plurality of grid samples;
• extract a plurality of illuminant features based on a green/NIR pixel ratio and a blue/NIR pixel ratio;
• estimate at least one illuminant feature for each of the plurality of grid samples by passing the each of the plurality of grid samples through a convolution neural network (CNN) module using the extracted plurality of illuminant features;
• process the image based on the estimated at least one illuminant feature;
• and
• display the processed image on a display panel of the electronic device.
