Embodiment Construction

[0045] In order to make the technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0046] The embodiment of the present invention is applied, for example, to a video camera with two image sensors, each image sensor has a shutter for controlling its shutter speed, and the shutter can be a mechanical shutter or an electronic shutter. The camera includes a lens, and a beam splitter is arranged behind the lens. The beam splitter splits the composite light received by the lens to obtain visible light and infrared light, and sends the visible light to an image sensor, and sends the infrared light to another image sensor. middle. The camera also has an image fusion function, which can fuse images acquired by two image sensors to obtain a target image.

Abstract

The invention provides an image shooting method and a camera, and relates to the technical field of image processing, and the method comprises the steps: carrying out the light splitting of received composite light, and obtaining visible light and infrared light; receiving the visible light on a first image sensor, and acquiring a first image according to a first shutter speed; receiving the infrared light on a second image sensor, acquiring a second image according to a second shutter speed, and the first shutter speed is larger than the second shutter speed; and carrying out image fusion onthe first image and the second image which are obtained at the same time to obtain a target image. According to the method, under the condition of weak visible light, the infrared light which cannot be perceived by human eyes can be fully utilized, the brightness and definition of the obtained image are higher while the original color rendition is maintained, and more identifiable information is provided.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for capturing images and a camera. Background technique [0002] With the development of technology, cameras have become an indispensable tool. The camera can be used in a series of security activities such as security inspection, real-time control, investigation and evidence collection, which provides us with a lot of convenience. For example, the camera on the road monitors the vehicles on the road and captures the target vehicle, so that it can be identified according to the photos taken in the subsequent process. In order to accurately identify the vehicle, it is necessary to ensure that the license plate number of the vehicle, the relevant information of the vehicle body and the details of the surrounding environment of the vehicle can be identified in the captured pictures. When the ambient brightness is low, such as at night, the shutter speed is genera...
