Description

{In dark places, using method of the front camera using a screen of a mobile terminal}

According to the present invention, when an application corresponding to an application is selected on a screen of a mobile terminal and the application is executed while illuminating the face on the front camera, light is generated on the screen, so that the user's face reflected on the screen of the portable terminal can be clearly photographed. Through the front camera of the user, the user can shoot the subject in a dark place without a separate flash, so it is convenient and easy to take a picture of the subject in a dark place such as at night, a blanket, or karaoke. You can make a video call regardless of time and place by using it, and it is possible to make a video call at night, so that there is no inconvenience to turn on a light or move to a bright place to make a video call. The front camera Brightness and sharpness of incoming image data can be set on its own, and the brightness and sharpness of the image data can be set high in the application itself, thereby greatly reducing the burden on eyes caused by bright backlight. This is a technique for using the front camera using the screen of the mobile terminal in a dark place to improve the convenience and satisfaction of the.

Current mobile terminals are becoming a device that can use various types of information as well as voice call function. In particular, as a user's demand for a mobile terminal moves to a smart phone, types of functions and applications implemented in the mobile terminal are increasing at a rapid rate.

Also, as the listening cell phone evolves into the cell phone that it sees, imaginary things are now becoming a part of natural daily life. Being able to take pictures and watch videos on a cell phone that you only talk and listen to is already a long time ago, and even video calls that allow you to talk to each other on the phone.

In the era of voice information, the mobile phone has evolved from the stage of video information to the next level. Moreover, its use is becoming innumerable as mobile phones are transformed into information management and entertainment terminals rather than communication means. The more you see and enjoy, the more important the display on your phone.

The video call feature, which lets you show your face and make phone calls while looking at the other person's face, is one of the most interesting and useful mobile phone features. Freely moving and making video calls is very convenient and useful when used well.

To take advantage of these video calls, the camera needs to have enough light to recognize your face.

However, in the case of a mobile phone capable of making a video call, the picture quality of the captured image is very poor when the surrounding environment is dark, or the picture quality can not be recognized at all. Due to these limitations, a problem arises in that it cannot be applied to a mobile phone providing a free call regardless of a place that can be said to be the biggest advantage of the mobile phone.

As a result, a user may freely make a video call without restriction in place, resulting in great inconvenience.

In addition, there is a problem that it is difficult not only to make a video call in a dark place, but also to take a picture of oneself who cannot receive a flash. Where there is no such dark or light, the camera of the mobile phone has a limit that is useless.

Therefore, the light is generated on the screen, so that you can take a clear picture of your face reflected on the screen of the mobile terminal, and through the front camera of the mobile terminal, the user can shoot a subject in a dark place without having to use a separate flash at night or bedding You can easily and easily take pictures of subjects in dark places such as inside and karaoke, and use the screen of a mobile terminal in a dark place where you can make video calls regardless of time and place using the screen and front camera. The development of the use of the front camera is urgently required.

Accordingly, the present invention has been conceived to solve the above problems, by selecting the icon corresponding to the application on the screen of the mobile terminal, when the application is executed while illuminating the face on the front camera, the light is generated on the screen, so that the light is reflected on the screen of the mobile terminal. The purpose of the present invention is to provide a method of using the front camera using the screen of the mobile terminal in a dark place that can clearly photograph the face.

Another object of the present invention is that the user can shoot a subject in a dark place without a separate flash through the front camera of the mobile terminal, so that the image of the subject can be conveniently and easily taken at night or in a dark place such as a blanket or karaoke.
