Problems solved by technology

[0003] However, the current keying technology is used in a small range and cannot be combined with the current teaching. In the traditional multimedia teaching process, LED screens, TV screens and other display devices often have disadvantages such as flickering screens, reflections, and image attenuation. It is also mixed with problems such as the inconsistency between the screen of the multimedia teaching class and the screen of the teacher, and the high cost of the large display screen, which will greatly reduce the learning effect of the students, thereby reducing the quality of teaching

Abstract

The invention discloses a portable half-range image matting blackboard, and the blackboard comprises the following steps: arranging equipment, selecting a proper teaching classroom, moving the portable blackboard to a position where the portable blackboard needs to be used, placing a stored image matting blue cloth wall calendar on one side of the portable blackboard, and then adjusting online teaching equipment for subsequent use. The system is mainly used for online teaching and teaching video production, not only can effectively overcome the defects of splash screen, light reflection, image attenuation and the like caused by display equipment such as an LED screen and a television screen in the shooting process, but also can overcome the problems that the proportion of pictures and teacher pictures in multimedia teaching of a general recording and broadcasting system is not coordinated, the cost of a large display screen is high, and the like; therefore, the teaching quality can be effectively improved.

Description

technical field [0001] The invention relates to the field of teaching technology, in particular to a convenient half-frame matting blackboard. Background technique [0002] The term "keying" comes from early television production. It is called "Key" in English, which means to absorb a certain color in the picture as a transparent color, and cut it out of the picture, so that the background can be seen through, forming a superimposed composition of the two-layer picture. In this way, the characters shot indoors are superimposed with various scenes after keying, forming a magical artistic effect. [0003] However, the current keying technology is used in a small range and cannot be combined with the current teaching. In the traditional multimedia teaching process, LED screens, TV screens and other display devices often have disadvantages such as flickering screens, reflections, and image attenuation. It is also mixed with problems such as the inconsistency between the screen...
