Capturing images using a predetermined motion to activate a button

摘要

An image capturing device (100) has an image sensor (200) for capturing images, a button controller (500) and a trigger detection unit (400) to detect a trigger condition based on a predetermined movement of the device. In response to the trigger condition S10 being detected by the trigger detection unit, the button controller activates a button S20 which on activation can receive an input from the user (e.g. pressing or selecting) S30 that is indicative of the user wanting to capture the image S40. As such, the button which receives user input indicative of the user wanting to capture the image is activated in response to the predetermined movement of the device. In effect, the device is put into camera-mode by the predetermined movement. The image sensor could be a camera in a mobile device. The movement could be sensed using accelerometers or gyroscopes. The button could be a hard-button or an icon on a touch-sensitive screen.
