Problems solved by technology

Because the human eye and the image sensor respond differently to each wavelength, the human eye cannot see infrared light (IR, Infrared Radiation), but the image sensor can sense it. The image sensor is sensitive to both red light and infrared light, and too much red in the color will affect The color reproduction of the image makes it difficult to debug and restore the photos taken to look like the real scene
In addition, too much red light is easy to form stray light and cause the problem of flare

Embodiment Construction

[0012] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0013] The IR cut filter in the prior art is usually placed between the image sensor and the lens group, that is, the IR is built-in. The embodiment of the present invention changes this traditional design idea, and changes the infrared cut filter from built-in to external, which can reduce the length of the rear focus of the lens group, thereby reducing the overall height of the module.

[0014] An embodiment of the present invention provides a camera module, which can be applied to various electronic devices, such as smart phones, tablet computers / IPADs, personal digital assistants (PDAs), and portable notebook computers. The camera module includes a lens group, an image sensor and an infrared cut-off filter, wherein the image sensor and the infrared c...

Abstract

The present invention provides an electronic device and a camera module. The camera module comprises a lens group, an image sensor and an infrared cut filter. The image sensor and the infrared cut filter are arranged at two sides of the lens group. Through changing the infrared cut filter to an external mode from an internal mode, while red light is eliminated, the rear focal length of the lens group can be reduced significantly, thus the overall height of the lens group is reduced, the thin structure design of the electronic device is facilitated, and the use experience of the electronic device of the user is improved.

Description

technical field [0001] The invention relates to the technical field of camera modules, in particular to an electronic device and a camera module thereof. Background technique [0002] At present, the camera function has become a common configuration on user terminal equipment. Most user terminal equipment (including mobile phones, tablet computers / PADs, etc.) Convert, record and save image information, so as to realize the function of taking pictures and photography. [0003] In the camera module, an image sensor (Sensor) is used to convert optical signals into electrical signals. Because the human eye and the image sensor respond differently to each wavelength, the human eye cannot see infrared light (IR, Infrared Radiation), but the image sensor can sense it. The image sensor is sensitive to both red light and infrared light, and too much red in the color will affect The color reproduction of the image makes it difficult to debug and restore the photos taken to look like...
