Abstract

The invention discloses a high-resolution moving image acquiring lens and an automobile data recorder with the same. The high-resolution moving image acquiring lens comprises a lens frame, a front pressing cover and a rear pressing cover. The inside of the lens frame is sequentially provided with a plano-concave lens, a convex-plano lens, a positive meniscus concave-convex lens, a first biconvex lens, a negative meniscus concave-convex lens and a second biconvex lens in a direction from an object-near side to an object-far side. Space rings are arranged between the plano-concave lens and the convex-plano lens as well as between the positive meniscus concave-convex lens and the first biconvex lens, and the contact surfaces between the first biconvex lens and the negative meniscus concave-convex lens are glued together. By utilizing the structure above of the high-resolution moving image acquiring lens, the automobile data recorder has the advantages of small viewing hole, no dark corner in field of view, large lighting quantity, no defocus and good night viewing effects, the focal distance is 3.6mm, and the resolution rate can reach up to five megapixel.

Description

technical field [0001] The invention belongs to the technical field of static and dynamic image acquisition equipment, and in particular relates to a high-pixel dynamic image acquisition lens and a driving recorder using the lens. Background technique [0002] In terms of long-distance image acquisition equipment, the combination of lenses inside the lens and the material of the lens determine the image acquisition effect, but at present, how some video image acquisition equipment achieves high pixels by adjusting the lens, but the amount of light is often insufficient to meet Day and night dual-use image acquisition requirements; when the amount of lighting meets the requirements and meets the day and night dual-use requirements, the pixels are often too low to achieve clarity, and the viewing range is small and the effect is not good. When the requirement of viewing range is large, it often cannot meet the requirement of clarity when the object moves dynamically. [0003]...
