Description

Picture-clip-turning contrast analysis device based on Chinese and foreign art history

Technical Field

The invention relates to the technical field of teaching devices, in particular to a device for clamp-turning, comparison and analysis of pictures based on Chinese and foreign art history.

Background

The history of Chinese art is long-running. Unlike europe, where the style of art is always changing, china art has remained a surprising continuation for centuries. The work in Ming dynasty can also see the effect of Tang dynasty. The composition of a Qing dynasty was very similar to that of a Song dynasty. One reason is that china is honored by the tradition. The primary task of an artist is not innovation, but the original works are copied as lifelike as possible, which is not considered as plagiarism but is innovative to a certain extent, at present, many universities have Chinese and foreign art history courses corresponding to major, and different pictures need to be compared during teaching, so that a device for comparison is needed.

For example, patent No. 201721190528.5 discloses a teaching device for Chinese and foreign art history with contrast areas, which comprises universal wheels, a leg frame and a vertical plate, wherein the universal wheels are fixed on the bottom side of the leg frame through bolts; the leg frames are arranged at the lower part of the hydraulic telescopic rod and are arranged at four positions, and the leg frames are uniformly distributed around the hydraulic telescopic rod at intervals of 90 degrees in pairs; the drawer is fixedly connected to the bottom of the bottom plate through screws and is provided with four positions; the vertical plate is fixed on the top side of the bottom plate; the slot is arranged in the center of the right side of the vertical plate; the drawing board is connected to the right side of the vertical plate through a pin shaft at the top and can rotate around the pin shaft by 90 degrees anticlockwise; the inserting plate is fixed on the drawing board through a T-shaped groove; the T-shaped groove is formed in the top of the drawing board; the supporting rod groove is formed in the center of the back of the drawing board; the side bottom of first display screen and second display screen is located to the data transmission district, simple structure, and low cost can realize drawing teaching, drawing show teaching and electronic drawing teaching simultaneously.

Based on the above, most of the existing image comparison and analysis devices rely on shooting and then displaying images on a screen when the images are compared and displayed, the screen has slight color difference, the original image effect is difficult to see, and other devices can fix the images through tensioning of rubber bands; therefore, the existing requirements are not met, and a picture clip-turning contrast analysis device based on Chinese and foreign art history is provided for the picture.
