摘要:
The purpose of the present invention is to enable light having a desired light intensity to be outputted in a broad brightness range spanning from low to high brightness, even if light intensity characteristics of light sources have been changed. Light sources (11) emit inspection light of a fixed output and image light of an output based on an image signal. A light-branching unit (15) branches the light from the light sources (11). A light detection unit (16) detects the light intensity of reflected light (C1) branched by the light-branching unit (15). A signal conversion unit (500) converts a first detection signal (P1) from the light detection unit (16), and outputs the resultant signal as a third detection signal (P3). A main control unit (400) inputs the third detection signal (P3), and controls the output of the image light on the basis of the third detection signal (P3) . A refresh unit (600) refreshes the third detection signal (P3) inputted to the main control unit (400).
摘要(中):
本发明的目的在于,即使光源的光强度特性已经变化,也能够以从低亮度到高亮度的宽泛的亮度范围输出具有期望的光强度的光。 光源(11)基于图像信号发射固定输出的检测光和输出的图像光。 光分支单元(15)分支来自光源(11)的光。 光检测单元(16)检测由光分支单元(15)分支的反射光(C1)的光强度。 信号转换单元(500)将来自光检测单元(16)的第一检测信号(P1)转换,并输出作为第三检测信号(P3)的结果信号。 主控制单元(400)输入第三检测信号(P3),并且基于第三检测信号(P3)控制图像光的输出。 刷新单元(600)刷新输入到主控制单元(400)的第三检测信号(P3)。
