Embodiment Construction

[0045] The film editing and screening auxiliary device based on the characteristics of the electroencephalogram signal of the present invention can be used for film editing in the process of film production, can also be used for grading the content of the film, and can also screen the film for individuals. According to the basic device and method of the invention, different specific applications can be developed, not only for video content evaluation, but also for other types of file content evaluation, such as image content evaluation or audio content evaluation. The detailed instructions for use are as follows:

[0046] The basic principle of the present invention is that when a user watches a movie, the movie content stimulates to induce relevant EEG signals, collects these EEG signals and sends them to a trained and more accurate classifier for category identification, helping users evaluate video content.

[0047] like figure 1 As shown, a schematic diagram of the device...

Abstract

The invention discloses a film editing and selecting auxiliary instrument and a realization method both based on characteristics of an electroencephalogram signal. The instrument mainly includes an electroencephalogram signal acquiring device, an electroencephalogram signal processing device, an electroencephalogram signal analyzing device and an output response device, wherein the electroencephalogram signal acquiring device comprises a plurality of brain region electrodes and is used for acquiring the electroencephalogram signal of a user watching a movie; the brain region electrodes are connected with an amplifier in the electroencephalogram signal processing device; the electroencephalogram signal processing device, the electroencephalogram signal analyzing device and the output response device are connected in sequence; and the final result is displayed on a liquid crystal display screen of the output response device. The film editing and selecting auxiliary instrument can be used in film production process for editing films, can be used for grading the contents of the films, and can select the films for an individual. Through acquiring the electroencephalogram signal of a spectator for evaluating the contents of the films, the influence of subjective experiences can be overcome, and the evaluation result is enabled to be more objective.

Description

technical field [0001] The invention relates to a device for analyzing electroencephalogram signals, in particular to an apparatus for objectively editing and screening film works based on the characteristics of electroencephalogram signals. Background technique [0002] In 1924, German psychiatry professor Ham Berger inserted two platinum needle-shaped electrodes into the cerebral cortex of patients with head trauma, and successfully recorded regular electrical activity. This discovery opened the prelude to the human study of brain physiological signals. [0003] With the continuous advancement of science and technology, scientists have discovered event-related potentials (ERP, event-related potentials) to observe the process of brain activity. ERP components associated with cognitive processes such as updating of working memory content, and through experiments, it can be found that different stimuli can induce different components, and different stimuli can also cause chan...
