Camera module and forming method thereof

Various embodiments of the present disclosure are directed to a camera module including a planar lens and a method of forming the same. According to the present invention, the planar lens has a reduced thickness compared to other types of lenses, whereby the camera module may have a smaller size, and a camera bump may be omitted or a size of the camera bump may be reduced on a mobile phone or the like incorporating the camera module. The planar lens is configured to concentrate visible light into a white light beam, separate the light beam into red, green and blue sub-beams, and guide the sub-beams to separate image sensors for red, green and blue light, respectively. The image sensor generates images of corresponding colors, and the images are combined into a panchromatic image. Optically separating the beam into sub-beams and using separate image sensors for the sub-beams allows omission of color filters and smaller pixel sensors. This in turn allows for higher quality imaging. 本公开的各种实施例针对包括平面透镜的相机模组及其形成方法。
