Abstract

The present invention provides a true digital rangefinder structure, camera and macular focusing method. The lens is used to replace the viewfinder and rangefinder window of the traditional rangefinder, and the CMOS image sensor (CIS) is arranged in the linkage device of the traditional rangefinder. The linkage device can change the position, a reflector is set between the lens and the CIS, and a miniature high-brightness LCD screen is used to replace the macular window of the traditional rangefinder. In this way, the light coming in from the lens is transmitted to the CIS after passing through the reflector. The image after CIS imaging is transmitted to the LCD screen, and the image of the LCD screen is transmitted to the visual window, and then forms a macular imaging effect with the image of the viewfinder window, so as to realize the macular focusing of the true digital range axis; therefore, the present invention can truly realize The digital autofocus of the macula displays histogram, time, ISO and other information when focusing, and can get high-quality images.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a true digital rangefinder structure, a camera with a true digital rangefinder structure, and a macular focusing method. Background technique [0002] Rangefinder cameras, also known as rangefinder viewfinder cameras, are named "rangefinder" cameras because the optical axis of the viewfinder is located next to the optical axis of the photographic lens and parallel to each other. [0003] The rangefinder cameras currently on the market are mainly divided into two categories, the digital rangefinder camera represented by Leica of Germany and the pseudo rangefinder camera represented by Japan Fuji. [0004] Digital rangefinder cameras from Leica Germany, such as figure 1 , using the distance measuring window 101 and the viewfinder window 106 to view the view, the first incident light is reflected by the reflector 102 to the linkage device 103, and then transmitted to the vis...
