Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0025] It should also be noted that the orientation terms such as left, right, up, and down in the embodiments of the present invention are only relative concepts or refer to the normal use state of the product, and should ...

Abstract

The invention belongs to the optical imaging field and provides a lens and a photographing device. The lens includes a lens barrel and a lens group arranged between a light inlet and light outlets of the lens barrel; the lens barrel is provided with one coaxial light outlet which is coaxial with the light inlet, and at least one vertical light outlet; the vertical light outlet is arranged between the light inlet and the coaxial light outlet; a 90-degree angle is formed between the axial direction of the vertical light outlet and the axial direction of the light inlet; a transmission and refection beam splitter is arranged between the coaxial light outlet and the vertical light outlet; the center of the transmission and refection beam splitter is located at the point of intersection of the center axis of the coaxial light outlet and the center axis of the vertical light outlet; a 45-degree angle is formed between the mirror surface of the transmission and refection beam splitter and the axial direction of the vertical light outlet; and reflected light of the mirror surface of the transmission and refection beam splitter enters the vertical light outlet, and the transmitted light of the mirror surface of the transmission and refection beam splitter enters the coaxial light outlet. With the lens of the invention adopted, the problem of image overlapping which appears in a situation in which a traditional lens is utilized to photograph a moving object or a fusion exposure technology is used after moving photography can be solved.

Description

technical field [0001] The invention belongs to the field of optical imaging, in particular to a lens and a photographing device. Background technique [0002] The currently widely used lenses have one light inlet and one light outlet, which is sufficient for daily use. The light inlet is used for framing, the internal components of the lens are used to determine the size of the framing, depth of field, viewing angle, etc., and the light outlet is connected to the photoreceptor for final imaging. [0003] For application scenarios in low-light environments or high image quality requirements, ordinary technology for a single light outlet lens cannot meet the requirements of use. At present, the exposure fusion technology that improves image quality through the fusion of multiple photos is often used. Solve the above problems. Exposure fusion technology requires multiple photos to be obtained with different exposures in the same scene. When using traditional lens exposure fu...
