example 1

[0047] Example 1: Achieve 2.5x optical zoom

[0048] In this example, the field angle α of the first camera module 1 is 74°, the field angle β of the light steering mechanism 2 is 30°, and the object distance is 5000 mm. When the first camera module 1 and the light steering mechanism 2 When the incident light axis spacing d is equal to 8.5mm, OH is equal to 3768, x1 is -1331, x2 is 1348, the ratio (x1 / OH) of x1 to the length of the half-field area OH is -0.35, and x2 to the half-field area The ratio (x2 / OH) of the length OH is 0.36.

Abstract

The invention discloses a double-camera zooming module. The double-camera zooming module comprises a first shooting module (1), a light steering mechanism (2) and a second shooting module (3), whereinthe first shooting module (1) is a wide-angle shooting module, the second shooting module (3) is a zooming shooting module, the second shooting module (3) and the light steering mechanism (2) form aperiscopic shooting module, and light reflected by the light steering mechanism (2) is incident to a lens of the second shooting module (3). The double-camera zooming module is characterized in that the first shooting module (1) and the light steering mechanism (2) are arranged in a co-plane mode, and an interval between an incident optical axis of the first shooting module (1) and an incident optical axis of the light steering mechanism (2) is in a range of 5-15mm. The double-camera zooming module is advantaged in that the optical axis interval of the two shooting modules is designed to be areasonable distance interval, zooming operation of the double-camera zooming module can be realized, and imaging resolution is effectively improved.

Description

technical field [0001] The invention relates to a dual-camera zoom module, in particular to a dual-camera zoom module for mobile terminals. Background technique [0002] Chinese patent CN201480051999.0 discloses tilting actuation of a reflector, wherein a reflector and a base supporting the reflector are provided. According to this patent, different pivots are used to support the mirror, and elements such as magnets, FP coils, Hall sensors, and springs are used to control the mirror to avoid vibration during use. [0003] The mirror tilt actuation result is complex, the number of parts is large, and the manufacture and maintenance are complicated. Contents of the invention [0004] The object of the present invention is to provide a dual-camera zoom module, which enables the parallelism of light entering one of the camera modules and the prism in the dual-camera module to be high, the imaging quality to be high, the overall strength to be high, and mass production to be e...
