Abstract: A projector is provided. The projector includes: a projection part including a light source configured to project an image, an infrared emitter comprising circuitry configured to emit infrared ray to a projection area where the image is projected, an infrared camera module including an infrared camera configured to generate an image by photographing the projection area using an image sensor, a memory storing correction data including correction values for correcting brightness of the image, and at least one processor configured to: correct brightness of an image obtained through the infrared camera module using the correction data, and identify whether a touch input for the projected image is entered based on the corrected brightness, wherein the correction data is generated based on first correction data and second correction data, the first correction data includes correction values for correcting a decrease in intensity of the infrared ray according to a distance from the infrared emitter, and the second correction data includes correction values for correcting lens shading.
