Abstract
Disclosed are a camera module and a method of measuring a distance by using the same. The camera module includes a light source to irradiate a light, a film having a pattern through which the light irradiated by the light source passes, an image sensor to acquire an image of a subject, and a distance estimating module to estimate a distance from the subject by using the image acquired by the image sensor. The acquired image includes a pattern image projected by the light passing through the pattern, and the distance estimating module estimates the distance by using the pattern image.
