Video signal processing method and photographic equipment

Abstract

The invention discloses a video signal processing method and photographic equipment, and belongs to the field of video cameras. The method comprises the following steps of: acquiring a video signal, and dividing a plurality of frames of images in the video signal into two or more than two sub-images; primarily processing the two or more than two sub-images of the plurality of frames of images by using two or more than two image sensor processor (ISP) processing units; and outputting the processed two or more than two sub-images of the plurality of frames of images. The photographic equipment comprises a lens, a sensor, an image divider, a controller and the two or more than two ISP processing units. Image division is used, and the two or more than two ISP processing units are used for performing path division processing on the divided sub-images, so that the resolution of the output images can be improved, image blurring at splicing parts can be avoided, an ultrahigh-definition video camera can be implemented, and the shortcomings of gap overlapping or deficiency, color differences, asynchrony and the like caused by the use of a plurality of video cameras for image splicing in the conventional ultrahigh-definition video camera system are overcome.

Description

technical field [0001] The invention relates to the field of cameras, in particular to a video signal processing method and camera equipment. Background technique [0002] With the development of video technology, people are still pursuing higher video resolution and larger display screens. The telepresence (Teleprence) conference system is the most typical application. The existing technology uses multiple 1920*1080 displays to splice into a larger display, or uses multiple projectors to realize the reality of a high-resolution seamless large screen through fusion technology. Similarly, such an application also requires a super-high resolution camera, and the prior art uses multiple cameras for image splicing to provide a video source of super high resolution. [0003] After analyzing the prior art, the inventor finds that the prior art has at least the following disadvantages: [0004] In the prior art, a plurality of high-definition cameras are generally arranged at a c...

Problems solved by technology

When the images obtained by multiple high-definition cameras are directly stitched together, because the optical centers of the cameras do not coincide, only the scenes at a certain distance can be seamlessly stitched, and the scenes that are closer than this distance will lack some images at the stitching place, which is larger than this distance. The distant scene will repeat some images at the splicing point, resulting in unclear images and low resolution at the splicing point
