Image signal processing apparatus and method thereof in mobile communications terminal
First Claim
1. An image signal processing apparatus in a mobile communications terminal, comprising:
- a plurality of camera modules for capturing a subject;
a digital signal processor (DSP) for outputting a switch control signal and control signals to control the plurality of camera modules according to a capture mode, and processing an image signal into a digital signal; and
a switch module distributing the control signals of the DSP to the plurality of camera modules, and selectively outputting image signals captured by the plurality of camera modules to the DSP according to the switch control signal.

Abstract
An image signal processing apparatus and a method thereof which can simplify design of a circuit for controlling each of camera modules when a terminal has two camera modules therein, the image signal processing apparatus includes: first and second camera modules for capturing a subject; a digital signal processor for controlling each operation of the first and second camera modules and processing image signals captured by the first and the second camera modules; and a switch module for supplying control signals inputted through the digital signal processor to the first and second camera modules, and selectively outputting the image signals captured by the first and second camera modules to the digital signal processor.

18. A method for processing an image signal in a mobile communications terminal having a plurality of camera modules, comprising:
-
outputting, if a user selects one capture mode, control signals and a first switch control signal for the capture mode;
distributing the control signals to the first and second camera modules and selectively outputting first image signals captured by the first and second camera modules according to the first switch control signal outputting a new second switch control signal if the user selects one of the first and second camera modules again in the same capture mode; and
selectively outputting second image signals captured by the first and the second camera modules according to the second switch control signal. - View Dependent Claims (19, 20, 21, 22, 23, 24)
