Problems solved by technology

However, many special effect plug-ins only process a certain channel of the image, and the output result displayed on the special effect monitor may only display the image information of a certain color channel of the image. Therefore, how to obtain special effects from the image displayed on the special effect monitor The original color information of the input image is very necessary

Embodiment Construction

[0017] The present invention can complete the extraction of color information during the special effect processing process. In order to better illustrate the realization process, the realization steps of the present invention are introduced by taking the keying special effect as an example.

[0018] When we use a keying effect on the edited material, only the Alpha channel information of the image is displayed on the special effect monitor. In order to obtain the color information of a certain point or a certain area, we need to find the input through the input of the keying effect. The original image information, to get the real color we need. Therefore, obtaining the color information of the original input image is the key to solving the problem.

[0019] Since the inter-connection relationship between the effect plug-ins on the storyboard and on the flow chart is different, the methods for obtaining input image information are also different on different work pages. For ea...

Abstract

The invention discloses a method for picking a color of an adjustment interface of a special effect monitoring instrument. The method is used for picking the color in nonlinear editing and cutting software and video and audio later-stage specific processing and synthesis software. The technical problem is that an image is displayed on the special effect monitoring instrument, and original color information of an input special effect image is acquired at the same time. In order to solve the technical problem, bottom layer node information, current frame information and output pin information acquired according to input pin information are acquired by extracting image information on a special effect node; a topology relation of connection among nodes is finally established; and information of an input image is acquired. According to the method, the information of the input image of the current special effect plugin is acquired according to the connection relation of the nodes in a whole video special effect processing process, so that a color value of an appointed position can be acquired accurately; and furthermore, due to the mode, the image information in an appointed region on the adjustment interface of the special effect monitoring instrument can be acquired.

Description

technical field [0001] A color picking method in non-linear editing and editing software and video and audio post-processing and synthesis software. Background technique [0002] In non-linear editing and editing software and video and audio post-processing and synthesis software, many special effect plug-ins need to obtain some color information from the material. [0003] The most direct and intuitive method is to get the color of the current position through the eyedropper tool on the special effects monitor. However, many special effect plug-ins only process a certain channel of the image, and the output result displayed on the special effect monitor may only display the image information of a certain color channel of the image. Therefore, how to obtain special effects from the image displayed on the special effect monitor The original color information of the input image is very necessary. Contents of the invention [0004] In the context of the present invention, c...
