Problems solved by technology

[0003] However, in the camera device, in order to reduce the infrared light entering the image sensor, a filter is set between the lens and the image sensor to filter the light. Although the setting of the filter can have a better filtering effect on the infrared light, to avoid Produces virtual images, but it also brings glare or ghosting problems, which seriously affects the effect of backlight photography

Abstract

The invention relates to an electronic device, a camera device and an optical filter thereof, the optical filter comprises an infrared filtering part, a first antireflection film and a second antireflection film, the infrared filtering part is provided with a first surface and a second surface which are arranged oppositely, the first antireflection film is formed on the first surface, and the second antireflection film is formed on the second surface. According to the electronic device, the camera device and the optical filter thereof, the first antireflection film and the second antireflection film are arranged on the surfaces of the two sides of the infrared filtering part of the optical filter respectively, so that the overall reflectivity of the optical filter is greatly reduced, and the reflectivity of the optical filter is not greatly changed in the visible light band even under the condition of large-angle incidence; therefore, the phenomenon of glare or ghosting is avoided, sothat the camera device adopting the optical filter can improve the backlight photographing effect while maintaining the imaging effect.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to electronic equipment, an imaging device and an optical filter thereof. Background technique [0002] With the popularity of electronic devices such as smart phones and tablet computers, users pay more and more attention to the experience of using the electronic devices. In electronic devices with camera devices, it is usually necessary to use the camera device to realize the shooting function. [0003] However, in the camera device, in order to reduce the infrared light entering the image sensor, a filter is set between the lens and the image sensor to filter the light. Although the setting of the filter can have a better filtering effect on the infrared light, to avoid It produces virtual images, but it also brings glare or ghosting problems, which seriously affects the effect of backlight photography.
