Camera module
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.
1. A camera module, comprising:
a lens group including a plurality of lenses;
an imaging lens on which incident light from an external environment is reflected;
an image sensor for obtaining image data related to the external environment by means of the light; and
a filter portion for cutting light having a preset wavelength, and sectioned into a center zone on which light is incident at a first incidence angle, and a peripheral zone which surrounds the center zone and on which light is incident at a second incidence angle that is greater than the first incidence angle,
wherein the filter portion having the center zone and the peripheral zone is configured to cut light having different wavelengths, among the incident light having the first and second incidence angles,
wherein the filter portion includes a plurality of filter members,
wherein the plurality of filter members are coated on different surfaces among the plurality of lenses, the imaging lens and the image sensor, and
wherein the plurality of filter members are arranged in an overlapping manner on one area thereof, so as to cut light with the preset wavelength, among the incident light having the first and second incidence angles.
2. The camera module of claim 1 , wherein the filter portion is formed of a coating material cutting light with wavelengths except for infrared light, among the incident light.
3. The camera module of claim 1 , wherein the filter portion is formed of a coating material preventing a transmission of infrared light among the incident light.
4. The camera module of claim 1 , wherein at least one of the plurality of filter members is formed on at least one surface of the imaging lens.
5. The camera module of claim 1 , wherein at least one of the plurality of filter members is formed on one surface of the image sensor.
6. The camera module of claim 1 , further comprising a cover glass configuring a part of an outer surface of the camera module and made of a transparent material for allowing an introduction of light,
wherein at least one of the plurality of filter members is formed on one surface of the cover glass.
7. The camera module of claim 1 , wherein the center zone comprises an area on which light transmitted through the imaging lens is incident at an angle of 0°.
