Problems solved by technology

During driving, users mostly focus on the road conditions directly ahead. When users want to watch the images displayed on the head-up display during driving, users need to move their eyes to the front of the instrument panel seat or the windshield on the right front , causing the focal length of the user's eyes to change constantly, and the user's attention cannot always be focused on the road ahead, which may easily lead to traffic accidents

Abstract

The invention provides an optical imaging device. The optical imaging device comprises a housing, a display element, a first optical element and a second optical element, the display element, the first optical element and the second optical element are disposed in the housing, the display element is located at a position far from two times of focal length of the first optical element, a display image displayed by the display element is zoomed out by the first optical element and imaged at a position within one time of focal length of the second optical element, the display image zoomed out by the first optical element is zoomed in by the second optical element so as to generate a display image which is visually zoomed in and equivalently located in the distance, so that a user can view the display image which is zoomed in and equivalently located in the distance through the optical imaging device. The optical imaging device according to the invention uses the first optical element and the second optical element, the whole optical imaging path from the display element to the second optical element is shortened, and the size of the optical imaging device is reduced.

Description

technical field [0001] The present invention relates to an imaging device, in particular to an optical imaging device. Background technique [0002] Various display devices used in vehicles have been successively developed, such as driving recorders, satellite navigation, head up displays (head up displays, HUDs), among which head up displays have been widely used. However, taking the head-up display as an example, the displayed images are mostly projected on the windshield at the front left or right front of the dashboard seat. During driving, users mostly focus on the road conditions directly ahead. When users want to watch the images displayed on the head-up display during driving, users need to move their eyes to the front of the instrument panel seat or the windshield on the right front , causing the focal length of the user's eyes to change constantly, the user's attention cannot always be concentrated on the road conditions directly ahead, which easily leads to the o...
