Embodiment Construction
[0036] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0037] The core idea of the present invention is: the terminal confirms that the terminal is in the applicable environment of the method by acquiring the real-time geographic location and time, and obtains the sun altitude from the known date, time, latitude and longitude, and altitude. The maximum likelihood of incident angle, light intensity and color temperature invokes the corresponding glare algorithm model to achieve sunlight gla...

The invention discloses a sunlight glare suppression method and device based on time, positioning, a lens angle, incident light intensity and color temperature, which are used for solving the problem that when a lens directly faces or laterally faces the sun when a video is shot outdoors, a shot picture is influenced by glare spots appearing in the video. According to the method, the terminal confirms that the terminal is in a method applicable environment by acquiring a real-time geographic position and time, the sun height is obtained according to the known date, time, longitude and latitude and the altitude, and when an interference light source is in a lens, a corresponding glare algorithm model is called according to a light incident angle, light intensity and color temperature maximum likelihood, so the sunlight glare suppression of outdoor shooting is realized.
Description
technical field [0001] The invention relates to the field of video analysis and database, in particular to a method and device for suppressing sunlight glare based on time, location, lens angle, incident light intensity and color temperature. Background technique [0002] When shooting a video outdoors, when the lens is facing directly or sideways to the sun, it is very common that there will be glare in the video. There can be one or more spots of glare. It can be big or small. For a single relatively small glare, it is commonly known as ghosting. In most cases, glare is not what users want, especially strong glare, which affects the shooting picture. Among the four basic actions of shooting: push, pull and pan, the action of panning is the most likely to cause glare interference. At the same time, the front and rear interferences are inconsistent, so that users can clearly feel the existence of glare. This is the source of the problem to be solved by the present invent...
