Portable electronic device

The present invention relates to a portable electronic device, and more particularly to a portable electronic device that can use a headset device of a portable electronic device to control a portable electronic device to take a picture.

With the rapid development of multimedia technology, various portable electronic devices such as personal digital assistants (PDAs) and mobile phones have become more and more indispensable items for people's lives. At the same time that people are looking for a light and short appearance, they hope that their functions will be more powerful. Therefore, many portable electronic devices that integrate multimedia functions, such as MP3 playback and camera functions, have become mainstream products in the market and are popular among people.

The digital camera module in the mobile phone is mainly composed of a combination of an optical lens module and a photosensitive module for image recording purposes. At present, the development of mobile phone camera functions has reached advanced functions such as millions of pictures, auto focus, electronic shutter, optical zoom, etc., and the image quality has been greatly improved, and can be applied in various occasions, such as a low illumination environment such as a night scene. When it is necessary to shoot for a long time, it is necessary to have a stable bearing to maintain the image quality, and to avoid vibration when the shutter is pressed, but because the mobile phone itself is light, thin, short, and small, when the hand is photographed, the shutter is pressed. It is easy to cause shaking in an instant, which may result in poor image quality, and it is difficult to operate when the camera is held against the fixed end during long exposure. For the use of camera phones, people often use self-photographing, so they are often limited by the length of the control arm, which makes the shooting method limited, and there are many inconveniences.

The reason for this inconvenience is that the camera button of a portable electronic device such as a mobile phone is generally disposed at the end of the mobile phone body, and it is inconvenient to hold the mobile phone for shooting when using the camera function. For long time shooting, it is also difficult to avoid the problem of poor image quality caused by hand shake.

In view of the above, it is necessary to provide a portable electronic device with a camera button on the earphone device, thereby improving the convenience of controlling the photographing of the portable electronic device and improving the quality of the camera.

A portable electronic device includes a body and a headphone device, the body having a camera module and an information transceiving interface, the earphone device having a headphone body and an information transceiver module and an operation module disposed in the headphone body The information transmission and reception interface of the portable electronic device can transmit signals between the information transceiver module of the earphone device. The camera body is provided with a camera button. When the portable electronic device is in the camera mode, pressing the camera button can control the camera module of the portable electronic device to take a picture.

Compared with the prior art, the portable electronic device sets the camera button on the earphone device, so that the camera module of the portable electronic device can be controlled to take a picture by operating the camera button on the earphone device. By using the original peripheral accessories of the portable electronic device, the convenience of controlling the photographing of the portable electronic device can be improved, and the shooting quality can be improved. In addition, when self-photographing is performed, the distance of control can be increased, and the degree of freedom of photographing and image quality can be improved.
