Embodiment Construction

[0025] In order to improve the problem of insufficient brightness and unevenness of light projected by conventional digital data presentation devices, the present invention provides a digital data presentation device to solve the above problems and improve the projection quality of the object to be measured.

[0026] see figure 2 , which is a schematic diagram of component configuration of a digital data prompting device 2 according to a preferred embodiment of the present invention. In the present invention, the digital data presenting device 2 is a digital data presenter (visualizer). The digital data presentation device 2 is composed of an illumination system 21 and a photographing system 22. The function of the illumination system 21 is to provide a projection light to an object 23 to be projected, so that the object 23 to be projected can reflect the projection light , and at the same time, the projection light is sensed by the camera system 22, and then the image of th...

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...
