The advantages and spirit of the present invention will be further understood from the following detailed description of the invention.

The invention provides a portable electronic device capable of automatically taking a picture according to dynamic sensing and automatically taking pictures according to light sensing and a method for operating the same.

According to a first embodiment of the present invention, a portable electronic device having a camera function is provided. In fact, the portable electronic device can be a conventional camera, a digital camera, a camera phone, a PDA or other electronic device with camera functions. Please refer to FIG. 1 , which is a functional block diagram of the portable electronic device.

As shown in FIG. 1 , the portable electronic device 1 includes a dynamic sensing module 12 , a light sensing module 14 , an image capturing module 16 , and an image processing module 18 . The image capturing module 16 is coupled to the dynamic sensing module 12 and the light sensing module respectively. Group 14 and image processing module 18. Next, each module included in the portable electronic device 1 and its functions will be discussed separately.

First, the dynamic sensing module 12 will be introduced. In this embodiment, the dynamic sensing module 12 is configured to sense that the portable electronic device 1 moves information in one of a specific period. In fact, the specific period may be an exposure period when the portable electronic device 1 performs photographing; the movement information may be a displacement amount when the portable electronic device 1 moves.

In practical applications, the dynamic sensing module 12 can be a commonly used dynamic sensor, such as a G-sensor. In recent years, due to the rapid development of electronic sensing technology, dynamic sensors have been widely used in various electronic devices to sense the motion state of electronic devices, such as electronic devices being moved during a certain period of time. Dynamic parameters such as the acceleration, the amount of change in the tilt angle of the electronic device with respect to the reference angle. Then, the electronic device can further change the display screen or operation function of the electronic device according to the size of the dynamic parameter sensed by the electronic device. Therefore, the portable electronic device 1 uses the dynamic sensing module 12 to improve the shortcomings of the conventional camera.

During the exposure period of the portable electronic device 1, when the displacement amount of the portable electronic device 1 sensed by the dynamic sensing module 12 meets the first condition, the dynamic sensing module 12 generates the first signal. And transmitting the first signal to the image capturing module 16.

In this embodiment, the first condition means that the displacement amount of the portable electronic device 1 is within a range of displacement. The range of displacement can also be referred to as the sensitivity of the portable electronic device 1 for autofocus. When the displacement amount of the portable electronic device 1 does not exceed the displacement amount range, it means that the portable electronic device 1 is still within the tolerable range due to the influence of the user's hand vibration. In fact, the amount of displacement can be a preset value or set by the user. For example, if the three axial displacement ranges of the portable electronic device 1 are set to 5, as long as the portable electronic The displacement of the device 1 in three axial directions does not exceed 5, and the portable electronic device 1 automatically performs the focusing operation. Of course, the amount of displacement is not limited to three axial directions, and may be, for example, at least one of the axial directions.

Next, the light sensing module 14 will be introduced. The purpose of adding the light sensing module 14 to the portable electronic device 1 is to replace the function of the shutter button of the conventional camera, thereby improving the image blur caused by the camera pressing the shutter button.

Therefore, the second condition means that the light intensity is less than the light intensity threshold, that is, When the light intensity sensed by the light sensing module 14 is less than the threshold value, the light sensing module 14 generates a second signal and transmits the second signal to the image capturing module 16 .

In practice, the threshold value of the light intensity may be a preset value or set by the user; the user may use a finger or other object to slide or block the aperture of the light sensing module 14 to sense the light, so that the light sensing The intensity of the light sensed by the module 14 will be less than the threshold value. As long as the user needs to cover the light sensing module for a long time, the portable electronic device 1 will automatically take a picture, or it may be a preset value or set by the user.

After the portable electronic device 1 completes the auto-focusing, the user only needs to cover the aperture of the light sensing module 14 to sense the light with the finger, and the portable electronic device 1 automatically takes a picture. Thereby, the user can smoothly complete the photographing process without pressing the shutter button, so that the hand vibration phenomenon caused when the finger is pressed by the shutter button can be effectively avoided.
