The invention relates to a light supplement control apparatus and method of a photographing type scanner, and a photographing type scanner. The light supplement control apparatus comprises a first signal emission apparatus, a first signal receiving apparatus, a second signal emission apparatus, a second signal receiving apparatus and a control apparatus, wherein the first signal emission apparatus is arranged at the top surface of a base of the photographing type scanner, the first signal receiving apparatus is arranged at a photographing rod of the photographing type scanner, and the second signal emission apparatus and the second signal receiving apparatus are arranged at the side surface of the base; the first signal receiving apparatus is used for receiving signals emitted by the first signal emission apparatus so as to obtain first signal values; the second signal receiving apparatus is used for receiving signals formed when signals emitted by the second signal emission apparatus are reflected so as to obtain second signal values; and the control apparatus is used for, according to the first signal values and the second signal values, controlling a light supplement lamp of the photographing type scanner to be turned on and turned off. By using the scheme provided by the invention, misjudgment can be effectively prevented while automatic control of the light supplement lamp is realized.
Description
technical field [0001] The present invention relates to the technical field of image supplementary light, in particular to a photographic scanner light supplementary control device and method, and a photographic scanner. Background technique [0002] The traditional photographic scanner, commonly known as the high-speed camera, is a digital instrument that captures images and converts them into computers that can be displayed, edited, stored, and input. It is mainly connected to a computer terminal through a USB interface to complete the scanning of images. It is a common office equipment that converts the image into various file formats through the supporting tools of the computer. The use of photographic scanners has brought a lot of convenience to the office. [0003] Such as figure 1 As shown, a traditional photo scanner includes a base 1, a support rod 2, and a shooting rod 3, on which a supplementary light 4 and a camera (not shown) are arranged. In the existing met...
