Example Embodiment

[0037] As shown in Figure 1, a camera of the present invention is characterized in that it includes: lens 1-3, image preprocessing mirror A, image sensor 1-4, optical viewfinder 1-6, display 1-5, image preprocessing The treatment mirror contains a lens. 1-2 is the real object of the camera. The image reaches the sensor 1-4 through the translucent reflective lens A and is converted into an electric signal, and the electric signal is transmitted to the display 1-5 to display the image in real time. At the same time, a part of the light beam is reflected by the reflective lens A and reaches the optical viewfinder 1-6 to form an optical viewfinder virtual image. R is a light-shielding plate.

[0038] For example, when there is only one lens in the image preprocessing mirror, the lens can also be designed in a fixed form.

[0039] As shown in Figure 2, the structure diagram of the image pre-processing mirror with two color filter lenses.

Abstract

The invention discloses an image predisposing mirror between lens and image sensor of camera selectively and closely-openly, which comprises the following parts: lens with different optical properties with color filter to pass infrared only, color filter to pass visible light, color filter of kinds of color and metal coated semitransmitting reflector, wherein the lens can be selected to reach the shift function of infrared, visible light and specific scene shooting; the metal coated semitransmitting reflector separates the image from lens into two paths to optical viewer and image sensor, which realizes the real-time viewing function with the same structure as single-lens reflector camera.

Description

technical field [0001] The invention relates to a video camera. Background technique [0002] At present, the structure of a camera is composed of a lens, an image sensor, and a viewfinder. After the light beam of the image passes through the lens, it is directly directed to the image sensor, and the image electrical signal generated by the image sensor is used as the signal source of the viewfinder. One of the disadvantages of this structure is that there is no optical viewfinder to directly observe the scene through the lens, and high monitoring quality cannot be obtained; the second is that there is no optical image processing lens, and special camera effects cannot be achieved; the third is infrared images and natural light images There are overlapping and interference issues. Contents of the invention [0003] In order to overcome the problems of mutual interference between the infrared image and the natural light image of the existing camera and the inability to us...
