Embodiment Construction
[0058] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. 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.
[0059] The method for determining shooting parameters provided in the embodiments of the present invention may be applied to an application scenario in which a terminal device is used for video shooting or image shooting. Video camera products include optical accessories such as infrared fill light, visible light fill light, lighting or switchable filter. When these accessories open and close, it will cause the video image of the camera to be overexposed or und...

The invention provides a shooting parameter determination method and device and a storage medium, The method comprises the following steps of: according to the environment data of the environment where the terminal device is located; judging whether at least one optical accessory of the terminal device needs to be switched to a target state or not; if yes, obtaining a target state of at least oneoptical accessory, and at least one of the current exposure and the current time of the terminal device, according to the target state of the at least one optical accessory; and at least one of the current exposure quantity and the current moment inquires an image signal processing ISP parameter set database obtained in advance, a target ISP parameter set of the terminal device is obtained, and when at least one optical accessory is switched to a target state, shooting parameters of the terminal device are determined according to the target ISP parameter set. The corresponding shooting parameters are acquired according to the state of the optical accessory, so that the phenomenon of overexposure or underexposure of the image caused by the state change of the optical accessory is avoided, and the quality of the video image is improved.
Description
technical field [0001] The present invention relates to the technical field of intelligent terminals, in particular to a method, device and storage medium for determining shooting parameters. Background technique [0002] At present, with the development of the economy and the improvement of people's living standards, video cameras play an increasingly important role in users' daily life. In some cases, users need to obtain high-quality images. Video camera products include optical accessories such as infrared fill light, visible light fill light, illuminator, or switchable filter. When these accessories open and close, it will cause the video image of the camera to be over-exposed or under-exposed momentarily. [0003] In the prior art, when an image is momentarily overexposed or underexposed, the image processor of the video camera can gradually adjust the image signal processing (Image Signal Processor, ISP) parameter set in a stepwise manner. The ISP parameter set includ...
