Problems solved by technology

[0003] Generally, digital zoom technology will shorten the exposure time of the photographic lens and increase the brightness. Although this can reduce the user's hand shake and the image of the captured image, but the high brightness will also easily generate noise in the image and reduce the image quality.

Embodiment Construction

[0016] Please refer to figure 1 , which is a block diagram of an embodiment of the image capture device of the present invention. In the figure, the image capture device 70 includes a first lens module 10, a second lens module 20, an input unit 50, a control unit 80, a feature extraction unit 30, an image scaling and deformation unit 90, an image fusion unit 40, and a display unit 60 .

[0017] A shooting range of the first lens module 10 is larger than that of the second lens module 20 , and a viewing angle of the second lens module 20 is different from that of the first lens module 10 . In practice, the first lens module 10 and the second lens module 20 are disposed on the same side of the housing of the image capture device 70 and face the same direction. For example, the first lens module includes a wide-angle lens module (wide), the second lens module includes a telephoto lens module (tele), and the focal length of the second lens module is greater than that of the firs...

Abstract

The invention provides an image capture method and an image capture device using the method. This image capture method is applicable to an image capture device with a first lens module and a second lens module. The viewing angle of the first lens module is larger than that of the second lens module. The method includes: increasing the exposure time of the first lens module and reduce its photosensitive value, and use the first lens module to capture the first image; reduce the exposure time of the second lens module and increase its photosensitive value, and use the second lens module to capture the second image; respectively capture the first image and A plurality of image features in the second image are used to determine the area corresponding to the second image in the first image; finally, the second image is fused into the area in the first image to generate a shooting output image.

Description

technical field [0001] The present invention relates to an image capture method and an image capture device using the method, in particular to a method for improving the quality of shooting images by using two lenses with different viewing angles to achieve anti-shake and using the same Image capture device. Background technique [0002] Compared with the optical anti-shake technology, the digital anti-shake technology does not require an additional optical mechanism, which is beneficial to the thinning and reducing the cost of the camera. However, the digital zoom technology also has its problems to be solved. [0003] Generally, digital zoom technology will shorten the exposure time of the photographic lens and increase the brightness. Although this can reduce the user’s hand shake and the image of the captured image, but the high brightness will also easily generate noise in the image and reduce the image quality. Contents of the invention [0004] In view of the abov...
