Digital camera

Abstract

The utility model adopts a reflector which is specially arranged between the screen and the ocular of the optical finder. This reflector can realize the total reflection and open or close. When this reflector opens, the light path is unclosed; all images on the screen arrive at the ocular for optical framing. When this reflector closes, all images on the screen are reflected to the pick-up head for view finding, so that the pick-up head specially used for the camera can obtain the maximum brightness of the screen image. Currently, the existing digital camera fails to shot the IR picture. So, this utility model can block the infrared light. Thus, only visible light goes through the optical filter, or the visible light is blocked off and only infrared light goes through the optical filter. Therefore, the daily shooting or night shooting can be switched via the open or close of these two lenses.

Description

technical field [0001] The present invention relates to a digital camera. Background technique [0002] Digital cameras are divided into two categories, one is a digital single-lens reflex camera, and the other is a consumer digital camera. At present, the structure of a digital single-lens reflex camera is composed of a lens, a total reflection mirror, an image sensor, and a viewfinder. When the shutter is pressed, the front mirror is closed, and the light beam of the image passes through the lens, and is completely reflected to the optical viewfinder when it meets the mirror; when the shutter is pressed, the mirror opens, and the light beam of the image passes through the lens, and all of it is directed to the image sensor. The disadvantage of this structure is that when the shutter is pressed to view the view, the light beams of the image are all blocked by the mirror, the image sensor cannot be sensitive, and the composition of the viewfinder cannot be transmitted to th...

Problems solved by technology

[0003] In order to overcome the problem that the existing digital camera with the eyepiece half-transmitting reflector has a dark problem in the electronic viewfinder, the present invention adopts a viewfinder-specific total reflection reflective mirror arranged between the image screen of the optical viewfinder and the eyepiece, which can be opened and closed.

In order to overcome the problem that existing digital cameras cannot take pictures of infrared images, the present invention adopts an openable and closed color filter that blocks infrared light and only allows visible light to pass through or a color filter that blocks visible light and only allows infrared light to pass through, and switches the camera by opening and closing these two lenses Day shot or night shot function
