no. 1 Embodiment

[0019] See Figure 1 Shown is a light valve-based multi-optical camera of the present invention. In the first embodiment, the optical lens is a plane mirror, and the image sensor is placed under the lens group.

[0020] The invention provides a light valve-based multi-optical camera, which is characterized in that it includes a lens group, a light valve group, an optical lens group and an image sensor.

[0021] The lens group includes lenses with different performances such as color lenses, black-and-white lenses, telephoto lenses, and super wide-angle lenses, and the lenses with required functions are selected according to actual application conditions. Each lens corresponds to a light valve. By controlling the switch of the light valve, which way of light enters is determined in turn. The incoming light is reflected or refracted by the optical lens and then irradiates the photosensitive surface of the image sensor.

[0022] Preferably, the described light valve-based multi-...

no. 2 Embodiment

[0025] See Figure II Shown is a light valve-based multi-optical camera of the present invention. This embodiment is different from the first embodiment in that the second embodiment uses prisms for the optical lenses, and the image sensor is placed on the right side of the lens group.

[0026] The invention provides a light valve-based multi-optical camera, which is characterized in that it includes a lens group, a light valve group, an optical lens group, an image sensor and a controller.

[0027] The lens group includes lenses with different performances such as color lenses, black-and-white lenses, telephoto lenses, and super wide-angle lenses, and the lenses with required functions are selected according to actual application conditions. Each lens corresponds to a light valve. By controlling the switch of the light valve, which way of light enters is determined in turn.

Abstract

The invention relates to a multi-light-path camera based on a light valve. The multi-light-path camera has a multi-light-path image acquisition function. The multi-light-path camera controls the light valve set to open a light path or block the light path through the controller, and natural light is made to alternately pass through the lens combination optical lens set to reach the image sensor to form optical imaging. And the controller transmits the acquired image information to the image processor for processing or transmitting the image information. Due to the fact that multiple paths of optical images are collected, the performance of collecting three-dimensional images is achieved. The multi-optical-path camera based on the light valve has the advantages that the structure is simple, the equipment size is small, sequential collection of multi-path optical images can be completed by adopting a single image sensor, the number of image sensors is reduced, and the production cost of the camera is reduced.

Description

technical field [0001] The invention relates to the technical field of electronic products, in particular to a light valve-based multi-light path camera. The invention relates to the field of optical image acquisition, in particular to an optical path conversion structure which can acquire multiple optical images by using a single image sensor. Background technique [0002] Existing multi-camera mobile phone products require multiple image sensors to realize the multi-camera shooting function, and also require multiple image sensors to realize the imaging of multiple cameras in industrial camera applications. Its product structure is bulky, uses many image sensors, and costs high. [0003] It is undeniable that the multi-camera has indeed brought us many functions that cannot be achieved by a single camera of a mobile phone: a shallow depth of field blur effect with a large aperture, and more diverse shooting environment adaptations. Theoretically speaking, if you want to ...
