Abstract

The present invention relates to an optoelectronic seal impression comparison machine, and more specifically to a machine using the electric display screen to display the standard original seal impression image as the reference image for comparison. The image of the seal impression to be compared, through the optical path composed of the optical components, can be overlapped by projecting the image of the seal impression to be compared and the reference image onto the same optical plane so as to achieve the object for precise comparison of the seal impressions. Furthermore by alternating the brightness of each image for the overlapped but not matched image, it will generate the pulsating pictures due to the vision transience effect to achieve the function of rapid comparison for seal impressions.

Description

479204 Description of the invention (1) [Background of the invention] 1. Field of the invention The field of the present invention relates to a kind of utilization image, especially a reference mirror and a total reflection mirror for comparison. The light image and the reference image are projected on The purpose of the same optical material is five. The purpose of electronically displaying the glory image and the precise comparison with the originals to be studied. In addition, due to the effects of visual persistence ΐ function. B Caitongguan Technical Description M = Knowing seal comparison with A. Indetermination work, there is a square image on the seal H from 1 § 1〆 plane, also S now appears in the wide A t 祝 the phenomenon of wishing difference, Aunt, the device must have an image, so the double-printed seal f: the original seal image data ^, because the change in the image is small, for each seal = electricity check, there are often interactions between light and dark. The image displayed on the optical road plane of the comparison and printing of the optical and electronic screen is beaten, and the image is emphasized on the optical road plane. It is a seal comparison device. The standard original seal map image passes through the optical path to make the comparison stack. It achieves the seal stack but the disproportionate map print is quicker than the financial type. Because of the two maps, it is more necessary to configure only the image files that can be retrieved. Too many counts the wrong image work and document recognition. There is a wide comparison error between the display panel print and the LCD display. An electronic camera takes the single print image, and the image data file is checked by the computer. It is not only judged that it includes With its judgment, its check and settlement, The distance between the pictures of the pattern board is another, to capture, and the case and the electric judgment of the boundary and unique results exist and co-resolve, and therefore, the method of printing the clock to compare is whether the frame is in the brain or not. Ruler pattern, great
