Problems solved by technology

[0004] But these two methods have their own defects. In the method of focusing with the RGB camera first and then with the MONO camera, it needs to focus twice in a row, and the focusing time will increase a lot; and in weak light, the probability of camera focusing failure is relatively higher than that of ordinary cameras. Under high light, two consecutive focusing will lead to a greater probability of focusing failure; at the same t

Embodiment Construction

[0019] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0020] Such as figure 1 As shown, an image acquisition device includes: a focusing unit for driving a first camera and a second camera, wherein the first camera is driven to set the focal length of the first camera to infinity, and the The second camera focuses; the determination unit is used to determine whether the second camera is successfully focused; the image acquisition unit is used to collect the first image through the first camera after the second camera is successfully focused, and through the The second camera captures a second image.

[0021] The image acquisition device further includes a combining unit, configured to fuse the first image and the second image to obtain a third image and output it.

[0022] The third image ha...

Abstract

The present invention discloses an image collection device and method. The device comprises: a focusing unit configured to drive a first camera and a second camera, wherein the first camera is driven to set the focal length of the first camera to be infinity, and the second camera is driven to perform focusing; a determination unit configured to determine whether the second camera is successfully focused or not; an image collection unit configured to collect a first image through the first camera and collecting a second image through the second camera after the second is successfully focused. The image collection device and method allow a color camera to be directly pushed on the far focusing and allow a black and white video camera to perform normally focusing so as to reduce the focusing time and the risk of the focusing failure of the night mode shooting without adding the hardware technology difficulty.

Description

technical field [0001] The invention relates to the technical field of photography, in particular to an image acquisition device and an acquisition method. Background technique [0002] In recent years, with the rapid development of mobile phone camera functions, consumers' demand for cameras with more powerful functions has gradually increased. Night scene is a shooting scene commonly used by users, and its effect optimization can effectively improve the user experience of camera photography. At present, the commonly used night scene photography method in the industry is: use a color camera (RGB) and a black and white camera (MONO), and improve the night scene effect by fusing the images of the two cameras. [0003] In night scene photography, the brightness, details, and noise of the MONO camera are better than those of the RGB camera. Therefore, in the process of image fusion, the RGB camera is used to provide color, and the MONO camera provides brightness, details, etc....
