Description

Technical Field

[0001] The present application relates to the technical field of in-cabin cameras, and in particular to a decorative cover for a camera and a camera. Background Art

[0002] At present, cars are developing rapidly in the direction of intelligent driving, and in-cabin monitoring plays an important role in the safety configuration of intelligent driving. In-cabin monitoring can be used to monitor the facial expressions, mental states, body movements, and information such as children and items left behind by the main driver, co-driver, and rear passengers, and provide monitoring information for the driver and the driving system. Due to the particularity of the driving environment, the current in-cabin monitoring system needs to use infrared light sources for fill light in low-light environments to provide the camera with a sufficient brightness environment for in-cabin shooting and recording and algorithm recognition, which places high requirements on the camera's stray light processing and transmittance.

[0003] Currently, mainstream in-cabin surveillance cameras use an integrated decorative cover for infrared fill light. The light from the infrared light source will be reflected to the lens inside the integrated cover to form stray light crosstalk. In addition, the infrared light source will be diffusely reflected to the decorative cover body to become a secondary light source to form stray light interference. Therefore, the current integrated decorative cover will reduce image quality, affect algorithm recognition, and reduce safe driving capabilities. Utility Model Content

Rather, the examples described herein have been provided only to illustrate some of the many possible ways of implementing the methods, devices and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0024] Throughout the specification, when an element (such as a layer, a region, or a substrate) is described as being “on”, “connected to”, “bound to”, “over”, or “covering” another element, it may be directly “on”, “connected to”, “bound to”, “over”, or “covering” another element, or one or more other elements may be present between them. In contrast, when an element is described as being “directly on”, “directly connected to”, “directly bound to”, “directly over”, or “directly covering” another element, there may be no other elements present between them.

[0025] As used herein, the term "and / or" includes any one of the associated listed items and any combination of any two or more items.

[0026] Although terms such as "first," "second," and "third" may be used herein to describe various members, components, regions, layers, or portions, these members, components, regions, layers, or portions are not limited by these terms. Rather, these terms are only used to distinguish one member, component, region, layer, or portion from another member, component, region, layer, or portion. Therefore, without departing from the teachings of the examples described herein, the first member, component, region, layer, or portion referred to may also be referred to as the second member, component, region, layer, or portion.

Such spatial relational terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is turned over, an element described as being "above" or "upper" relative to another element will subsequently be "below" or "lower" relative to the other element. Therefore, the term "above" includes both "above" and "below" orientations depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relational terms used herein will be interpreted accordingly.
