Problems solved by technology

However, since multiple image sensors in a camera with an ultra-wide-angle lens are distributed in a two-dimensional plane, the virtual image captured by the camera will be distorted, resulting in a mismatch between the test result and the actual viewing situation of the human eye, resulting in the existence of a test result. error

Embodiment Construction

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the display effect testing device provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] see figure 1 , the existing display effect testing device includes an optical lens 3 and an image sensor 4, wherein the optical lens 3 is used to image the image displayed by the display screen 2 of the display device 1 under test in the image sensor 4; The optical signal of the image is converted into an electrical signal for evaluating the display effect of the display device 1 under test.

[0027] see figure 2 , there are a plurality of image sensors 4 arranged in an array, and the photosensitive surfaces 41 of the plurality of image sensors 4 form a two-dimensional plane 411, which will lead to distortion of the finally obtained image, thus causing the test results to be different from those obser...

Abstract

The invention provides a display effect test device. The device comprises an image collection unit and an image processing unit; the image collection unit is used for collecting light signals emittedby the display image of a tested display device and sending the light signals to the image processing unit; the image processing unit is used for converting the light signals into electrical signals;the image processing unit comprises a photosensitive curved surface; the photosensitive curved surface is opposite to the image collection unit and is used for receiving the light signals; and the shape of the photosensitive curved surface is similar to the shape of the eye of a person. The display effect test device provided by the present invention can more realistically reflect the effect of the watching of the tested display device by the eye.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display effect testing device. Background technique [0002] A virtual reality head-mounted display device, that is, a VR (virtual reality) head-mounted display, is a brand-new technology in modern display technology, and has very important applications in aspects such as augmented display, virtual reality, and stereoscopic display. [0003] At present, in order to evaluate the display effect of VR headsets, a camera with an ultra-wide-angle lens is used to get close to the VR headsets to capture the virtual image information of the VR headsets to simulate the effect of human eyes watching the VR headsets. However, since multiple image sensors in a camera with an ultra-wide-angle lens are distributed in a two-dimensional plane, the virtual image captured by the camera will be distorted, resulting in a mismatch between the test result and the actual viewing situation of...
