Virtual framing and photographing device for camera

Abstract

The invention discloses a virtual framing and photographing device for a camera. According to the virtual framing and photographing device for the camera, foreground and background pictures in a data storage unit of the device are called and are processed into an image which has been subjected to picture matting and background matching when framing signals of the camera are acquired, and then, the image is output to a virtual framing and displaying unit for displaying, so that a photographer can frame and photograph. When the signals are received by a photographing synchronous signal acquisition unit, the device imports a photograph into a multi-task processor from a photograph data acquisition unit, carries out corresponding picture matting and background matching work on the photograph, and stores the photograph into the data storage unit of the device. The virtual framing and photographing device for the camera can help the photographer frame and photograph by virtue of the processed image which has been subjected to picture matting and background matching when a mono-color background is photographed, so that a lot of money and time for background making are saved for studios, photography studios, photo galleries and the like, and a preferable background color effect is obtained.

Description

technical field [0001] The invention discloses a virtual viewfinder photographic device for a camera, which is small and can be installed on the camera very conveniently. By collecting the viewfinder signal of the camera, the foreground and background pictures in the data storage unit of the device are called at the same time to process them into The images that seem to be matched with the background are cut out, and then output to the virtual viewfinder display unit for display by the photographer. When the photo synchronous signal acquisition unit receives the signal, the device imports the photo from the photo data acquisition unit into the multitasking processor and performs corresponding keying and background work on the photo, and then stores it in the data storage of the device within the unit. The present invention enables the photographer to take pictures with the processed image that has been processed into a cutout and matched with the background when shooting a mo...

Problems solved by technology

[0002] Nowadays, photography has entered the digital age in an all-round way. The convenience of digital photography and powerful post-processing have greatly increased people's enthusiasm for taking pictures. Photography practitioners such as photo studios, photography studios and photo studios are constantly changing more backgrounds. Or photography themes to meet the increasingly high aesthetic requirements of customers, the replaced background is often discarded, resulting in environmental pollution and great waste

For photography practitioners, the replacement of the background is also a big investment, so more and more practitioners start to take monochrome background shooting (usually blue or green background) and post-keying with background images to save money. Investment, and make the color texture of the background consistent (traditional backgrounds have disadvantages such as fading and the influence of light color temperature)

However, the method that photography practitioners currently adopt with a background image is: the photographer shoots for the customer in front of a monochrome background (the photographer has no way to watch the viewfinder image that has been keyed and matched with the background in real time when shooting, and can only rely on memory to arrange the position and proportion of the customer in the future background, rely on association to predict the final effect of the photo), and then use the camera data cable (or card reader) to import the photo data into the computer, and then use image processing It is very time-consuming and cumbersome to use software Adobe photoshop or other software to perform image keying and output with background. Based on the above-mentioned technical defects in the prior art, it is necessary to develop a virtual viewfinder photography device for cameras to meet the needs of the majority of photographers.
