Problems solved by technology

But there is such defect in the mobile phone that has camera in the prior art: it is to utilize baseband module 30 ' to control the operation of camera module 20 ' and LCD module 10 ' usually
[0005] First of all, since the image captured by the camera needs to pass through the baseband module before being transmitted to the LCD module, there is a delay of several frames between the image displayed on the LCD module and the actual picture;
[0006] Secondly, the structural design of the existing mobile communication device with a camera also causes an excessive load on the baseband module
The existence of these defects makes the above-mentioned device unable to achieve satisfactory use effect in actual operation, so the solution of new camera mobile communication terminal device is demanded

Embodiment Construction

[0022] In the following description, well-known functions or structures will not be described in detail to avoid unnecessary confusion with the content of the present invention.

[0023] figure 2 is a block diagram of an embodiment of a mobile phone with a camera according to the present invention, see figure 2 : For the camera module 20, the optical sensor 22 converts the light image captured by the lens 21 into an electrical image signal, and the video processing module 22 converts the electrical image signal input from the optical sensor 22 into a digital signal and further processes the converted digital signal After processing, it is sent to the LCD module 10 or the baseband module 30 .

[0024] The baseband module 30 is the core part of the whole device, it controls the whole operation of the mobile device, and is connected with the SIM card (Subscriber Identity Module user identification card), the storage module 60, the keyboard part 70, the audio module 90 and the ...

Abstract

The device comprises at least a picking up module, baseband module, and LCD module. The baseband module does not connect to the LCD module directly. The baseband module through the picking up module controls operation of LCD module. The picking up module provides a transparent bridge between the baseband module and the LCD module. Image and data are transferred between LCD module of the picking up module and the LCD module. Comparing with prior art, advantages of the invention are: delay phenomenon between displayed image and actual frame is better eliminated since the picking up module and LCD module is connected directly. Thus, user can capture any watched suitable image.

Description

technical field [0001] The invention relates to a mobile communication terminal device, in particular to a mobile communication terminal device with a camera. technical background [0002] In recent years, mobile communication technology has developed rapidly. Mobile communication devices, such as mobile phones, provide various additional functions in addition to original functions for the convenience of users. For example, Internet phones that can smoothly access the Internet and send and receive e-mails, TV phones combined with TV receivers, and camera phones combined with cameras, etc. This composite mobile phone is popular because it improves the efficiency of applications and facilitates users. [0003] Along with the continuous innovation of image technology, it will be the general trend to carry out multimedia communication, and the kind of mobile phone with camera that combines mobile phone and video camera to be able to carry out image acquisition and transmission ...
