Abstract
An image capture method is provided for a portable communication device having a display unit, which real-time displays an image at least including an object to be shot. The method includes sensing a moving acceleration of the portable communication device based on a first gravity-sensing threshold value. A touch focus signal is received so that the portable communication device focuses on one of the objects to be the focus-lock object. Then, according to the touch focus signal, the first gravity-sensing threshold value is changed to a second gravity-sensing threshold value, which is larger than the first gravity-sensing threshold value. The image at least including the focus-lock object is captured.
Claims10
An image capture method for a portable communication device being operated to capture an image including at least an object to be shot while sensing an environmental brightness is not enough, the image capture method comprising:
- performing a preliminary auto-focus operation for automatically focusing on at least one of the objects to be shot at least once;
- receiving an image capturing signal;
- performing a pre-capture auto-focus operation for automatically focusing on the focus-lock object by the portable communication device once more after the image capturing signal is received;
- and
- capturing the image including at least one of the objects to be shot after the pre-capture auto-focus operation is performed.
A portable communication device for being operated to capture an image including at least an object to be shot, the portable communication device comprising:
- a display unit for real-time displaying the image including at least one of the objects to be shot;
- a touch sensing unit for receiving a touch focus signal so that the portable communication device focuses on at least one of the objects to be shot as the focus-lock object;
- a gravity-sensing unit, wherein the gravity-sensing unit senses a moving acceleration based on a first gravity-sensing threshold value before the touch sensing unit receives the touch focus signal, and the gravity-sensing unit changes the first gravity-sensing threshold value to a second gravity-sensing threshold value after the touch sensing unit receives the touch focus signal, and the second gravity-sensing threshold value is larger than the first gravity-sensing threshold value;
- and
- an image capture unit for receiving an image capturing signal to capture the image including at least one of the objects to be shot.
