Problems solved by technology

The disadvantage of this method is that the amount of calculation is very large, and the accuracy and speed are not high enough; another method is direct forward imaging, where a half-transparent mirror is inserted in front of the display screen, and the camera is placed on the optical path of the vertical display , to realize the forward imaging of the human face, but the structure is relatively large

specific Embodiment

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Specific examples:

[0028] refer to figure 1 , the two-way imaging-display system comprises: liquid crystal panel display 11, is used for displaying image; Detector array 12, is used for detecting array imaging signal; Isolation plate 13, eliminates the signal crosstalk between microlens unit imaging; Microlens array 14, Used for far-field imaging of objects; observer (or object) 15.

[0029] Such as figure 2 As shown, the arrangement of the pixels of the liquid crystal panel display 11 is given, and four pixels are used in the illustration, and each pixel has a useless sub-pixel 16 in addition to three sub-pixels of R, G and B for display. .

[0030] Such as image 3 As shown, it corresponds to figure 2 The structure of the microlens array 14 . Each useless sub-pixel 16 corresponds to a microlens 17 . The transparent substr...

Abstract

The invention discloses a two-way imaging-display system based on micro lens array and panel display integration. The system comprises a micro lens array for imaging, a detector array for measuring optical signals on the image surface axis of the micro lens array, separators capable of eliminating signal crosstalk among images of micro lens units, and a panel display for display. The system has asimple structure, can acquire the image of front of a human face on the premise of not influencing the display, solve the problem of human eye contact in network videos and realize gesture recognition, and is applied to daily network video chatting / conference systems and optical contact-less human-computer interaction systems.

Description

technical field [0001] The invention relates to a two-way imaging-display system, in particular to a two-way imaging-display system based on the integration of a microlens array and a flat panel display. Background technique [0002] The rapid development of network technology enables people to communicate through video and audio. Compared with the general conference mode, this remote video conferencing system has the characteristics of low cost, so it has a wide application prospect. The traditional network video conferencing / chat system realizes imaging with the aid of a camera. When both parties in the video are paying attention to the displayed image on the display screen, the image captured by the camera is a side view of the person involved, which causes a problem called face-to-face communication difficulties, such as the inability of human eyes to look at each other, facial expressions and other information Much is lost. These issues reduce the effectiveness of we...
