Abstract
A plurality of lenses (-) of a lens module (), a plurality of wavelength selection regions (-) each having at least one optical filter, and a plurality of imaging regions (-) are placed in one-to-one correspondence. At least two of the plurality of wavelength selection regions transmit light in at least one wavelength band among infrared light, red light, green light, and blue light. The distance to an object is calculated based on at least two pieces of image information outputted respectively from at least two imaging regions respectively corresponding to the at least two wavelength selection regions. Furthermore, a camera module outputs an image signal based on image information outputted from at least one of the plurality of imaging regions. This can realize a small and low-cost camera module capable of measuring the distance to an object and capturing the object.
