AI Technical Summary

Problems solved by technology

However, each method has its own drawbacks
For example, motion-based methods are often time-consuming because they require multiple clock cycles and dedicated processor bandwidth
When used alone, histogram-based methods are often not precise enough to correctly detect scene cuts
As a final note, using image feature-based methods is generally more difficult and time-consuming than using motion-based methods

Embodiment Construction

[0013] Hereinafter, presently preferred embodiments of the present invention are specifically described. Of course, the invention is not limited to the embodiments discussed hereinafter or to the embodiments shown in the drawings. Rather, the description and drawings only show the preferred embodiments of the invention so far.

[0014] One or more specific embodiments of the invention are described below. Not all features of a particular implementation are described in the specification, which is intended to briefly describe these examples. It should be clear that the implementation process of this specific implementation plan is the same as the implementation process of any engineering project or design project. The implementer must make many, many decisions on the implementation plan in order to achieve the set goals, for example: to comply with System-related constraints and business-related constraints, and these constraints change as the implementation process changes. ...

Abstract

A device (14, 24) and a method (30) for the detection of scene switching through absolute histogram difference, SAHD, absolute display frame difference and SADFD, find out the change using the time information of a same scene to accurately detect the scene switching, and are capable of being used for real-time operations (such as real-time video compression) and non-real-time operations (such as post production of film).

Description

technical field [0001] The present invention relates to video processing, in particular to a method and device for detecting scene switching. Background technique [0002] This section is intended to introduce the reader to various backgrounds related to aspects of the invention that are described and / or claimed below. It is believed that the description herein will help to provide background information for the reader, so that the reader can understand all aspects of the present invention more clearly. Therefore, it can be considered that the purpose of the description herein is for the convenience of the reader, rather than as an admission of prior art. [0003] Typically, cinematic video content data is captured, stored, transmitted, processed and output as a series of still images. When still pictures are output in a sufficiently compact time period, viewers will perceive small changes in data content from frame to frame as motion, and large changes in data content bet...
