Photographing apparatus and photographing method

Abstract

The embodiments of the invention provide a photographing apparatus and a photographing method. The photographing apparatus comprises a photographing lens, a beam splitting component, at least two apertures, at least two imaging components and an image signal processor that are arranged in sequence; the at least two apertures are in one-to-one correspondence with the at least two imaging components; the photographing lens is used for collecting a light beam from a photographed target; the beam splitting component is used for splitting a light beam that passes through the photographing lens intodifferent light beams toward each of the at least two apertures, wherein the amount of light passing through each of the at least two apertures is set to be different from each other; each imaging component in the at least two imaging components is used for performing photoelectric conversion on a light beam that passes through a corresponding aperture to generate an initial image; and the imagesignal processor is used for performing image fusion processing on at least two initial images generated by the at least two imaging components to generate a target image. According to the apparatus and the method, on the basis of meeting the requirement on photographing performance, an image tail problem is solved; and an obtained image is clearer.

Description

technical field [0001] The present invention relates to the field of imaging, and more particularly relates to an imaging device and an imaging method. Background technique [0002] When the target area captured by the camera includes high-brightness areas irradiated by strong light sources (sunlight, lamps, or reflections, etc.) and areas with relatively low brightness caused by factors such as shadows and backlighting, the captured image will appear brighter and become white And the phenomenon that the darker area becomes black seriously affects the image quality. Wide dynamic technology is a technology used to allow the camera to see the characteristics of the image under very strong brightness contrast. [0003] The most common wide dynamic technologies are mostly developed based on a single camera. First, a camera is used to capture two or more images in succession with different exposure times. The longer the exposure time, the more electrical signals the light sign...

AI Technical Summary

Problems solved by technology

This processing method takes a long time to generate an image that meets the requirements

In addition, since a camera takes two or more images in chronological order, and the camera target itself may be in motion, there is a phenomenon of smear in the image obtained after image fusion processing
