Problems solved by technology

However, determining the exposure time when capturing images according to the detected ambient brightness does not help in capturing dynamic images of the subject
That is, the exposure time determined according to the brightness of the environment cannot accurately capture the moving moment of the dynamic subject, so the clarity of the captured image is affected, resulting in blurred images

Embodiment Construction

[0043] figure 1 It is a schematic diagram of an image capturing system according to an embodiment of the present invention. Please refer to figure 1 , the image capture system of this embodiment is suitable for a portable device 100 (please refer to figure 2 ). The portable device 100 is, for example, a personal digital assistant (PDA), a PDA mobile phone, a smart phone or a touch-sensitive mobile phone. In addition, the portable device 100 has a display unit 102 (please refer to figure 2 ), displaying at least one shooting entity (such as figure 2 A preview image (such as figure 2 preview image 202). It should be noted that the captured entity includes the object that the portable device 100 focuses on or the background object that the portable device 100 does not focus on.

[0044] The image capturing system includes: a brightness sensing unit 104 , a motion sensing unit 106 , a sensitivity modulating unit 108 , a shutter modulating unit 110 and an image capturing...

Abstract

An image acquisition method and an image acquisition system are provided. The image acquisition method is suitable for a portable device, which has a display unit to display a preview image comprising at least one photographing entity in a live-action manner. The image acquisition method comprises automatically setting a light sensitivity of the portable device as a first light sensitivity value according to the ambient brightness of a space where the photographing entity is located, sensing the relative movement between the portable device and the photographing entity, adjusting the first light sensitivity value of the light sensitivity to a second light sensitivity value when the relative movement is sensed, and acquiring the preview image at least comprising the photographing entity.

Description

technical field [0001] The present invention relates to a method and system for operating a portable device, in particular to an image capture method that changes the sensitivity value according to the relative position change between the portable device and the object to be photographed, and further changes the shutter speed accordingly with the system. Background technique [0002] In today's era of information explosion, human life is inseparable from electronic communication. It is quite common for people to use electronic communication devices to transmit information to each other, especially portable electronic devices that can be carried with them, such as mobile phones or An electronic device with wireless communication function. [0003] In today's increasingly developed mobile communication technology, the functions of mobile communication devices are still constantly being updated. In addition to functions such as listening to the radio, many mobile communicatio...
