Abstract

An apparatus and method for compensating for backlight in a mobile terminal with a camera, which includes a camera unit having a camera lens and an ultraviolet sensor, which are disposed adjacent to each other and oriented in a same direction; and a control unit for generating a photographing control signal when a photographing mode key is input and controlling compensation for backlight while in the photographing mode.

Description

technical field [0001] The present invention relates to portable terminals. In particular, the present invention relates to an apparatus and method for compensating backlight in a mobile terminal with a camera. Background technique [0002] The portable terminal can communicate with others through various functions including a text message function. The cellular phone can also incorporate a camera function for performing ordinary camera functions. In addition, a compact and light-weight portable phone with a camera function is more popular than a bulky general camera. [0003] When a user photographs an object with a portable phone with a camera, the object may be photographed by the backlight of the camera. Backlight means that the object is in a position with a light source behind it, and the photographer is shooting the object with the light source behind it. Since the camera is facing the light source, the object may be underexposed or completely black. As described...
