Digital data reminder

Abstract

A prompt device of digital data is prepared as emitting light by illumination unit and using lens set to send light to projection surface of object to be projected, setting image pick-up camera lens at one side of image sensing element, adjusting light to forward along reflection direction of object to be projected to let light enter into image sensing element through image pick-up camera lens by the first light deviation unit.

Description

technical field [0001] The present invention relates to a digital data prompting device, in particular to a digital data prompting device which can improve the effective utilization rate of projected light. Background technique [0002] The so-called digital data prompter is a device that captures the image of the object to be projected through a camera system, and then plays the image on the screen so that the public can watch it. The working principle of the digital data prompter is that when an object to be projected is illuminated by a light source, the image of the object to be projected is captured by a special charge-coupled device (CCD) or complementary metal-oxide-semiconductor (CMOS) camera lens, and The image of the object to be projected is then converted from the original image signal (analog signal) into an electronic signal (digital signal) by the action of the chip. When the electronic signal is input into the projector, the image can be presented on the scre...

Problems solved by technology

However, integrating the lighting system into this digital data prompter still cannot solve the problem of uneven brightness of the projected light, because the projected light provided by it will still diverge, so when it is irradiated on the object 15 to be projected, it will still cause The edge of the illuminated area is darker and the middle is brighter, which affects the quality of the image
