Abstract: Provided in the present invention is a camera module comprising: an imaging lens on which incident light from an external environment is reflected; and an image sensor for obtaining image data related to the external environment by means of the light, and further comprising a filter portion, which is arranged on the image sensor to cut light having a predetermined wavelength, is sectioned into a center zone in which the incidence angle of the light is a first incidence angle, and a peripheral zone surrounding the center zone in which the incidence angle of the light is a second incidence angle that is bigger than the first incidence angle, wherein the filter portion having the center zone and the peripheral zone is formed so that light having wavelengths that differ from the incident light having the first and second incidence angle is cut.

Abstract: An optical device includes: a first light emitting device that emits a plurality of line pattern lights spaced apart from each other to a target area; at least one sensor device that detects a received light, which is the emitted line pattern light, that is reflected from the target area; and a controller that calculates a parallax distance from a pattern of the detected received light, and acquires depth information of the target area by using the calculated parallax distance, wherein the first light emitting device includes: at least one light emitting unit including at least one light emitting element and emitting light of a specific wavelength; and a first optical member that generates light emitted from the at least one light emitting unit into at least one line pattern light.
