Embodiment 1

[0043] The method embodiment provided in Embodiment 1 of the present application may be implemented in a camera device, where the camera device may include a camera module in a security monitoring system, or a camera module provided for other purposes in other devices. image 3 It is a hardware structural block diagram of an imaging device according to Embodiment 1 of the present invention. like image 3 As shown, the camera device 30 may include: a camera 301, a photosensitive unit 302 and a processing unit 303, wherein,

[0044] The photosensitive unit 302 is configured to detect a photosensitive value;

[0045] The processing unit 303 is configured to:

[0046] In the case that the current day and night mode of the camera 30 is a night mode, if it is judged that the first night to day switching condition or the second night to day switching condition is satisfied, the current day and night mode is switched to the day mode; and / or,

[0047] In the case that the current ...

Embodiment 2

[0090] In this embodiment, a device for switching between day and night modes is also provided, which is used to implement the above embodiments and preferred implementation modes, and what has been explained will not be repeated here. As used below, the term "module" may be a combination of software and / or hardware that realizes a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementations in hardware, or a combination of software and hardware are also possible and contemplated.

[0091] Figure 5 is a structural block diagram of a day and night mode switching device according to an embodiment of the present invention, such as Figure 5 As shown, the device includes:

[0092] The first mode switching module 52 is set to: when the current day and night mode of the imaging device is the night mode, if it is judged that the first night to day switching condition or the second night to day switching...

Embodiment 3

[0098] An embodiment of the present invention also provides a storage medium, in which a computer program is stored, wherein the computer program is set to execute the steps in any one of the above method embodiments when running.

[0099] Optionally, in this embodiment, the above-mentioned storage medium may be configured to store a computer program for performing the following steps:

[0100] S1, when the current day and night mode of the imaging device is the night mode, if it is judged that the first night to day switching condition or the second night to day switching condition is satisfied, the current day and night mode is switched to the day mode. In an embodiment, the first night-to-day switching condition includes: the photosensitive value detected by the photosensitive unit of the camera device is greater than the night-to-day switching photosensitive threshold T3, and the photosensitive parameters of the camera meet the night-to-day brightness switching condition; ...

Abstract

The invention provides a day and night mode switching method and device, a camera device and a storage medium. According to the method, under the condition that the current day and night mode of the camera device is a night mode, if it is judged that a first night-to-day switching condition or a second night-to-day switching condition is met, the current day and night mode is switched into the daymode; and / or under the condition that the current day and night mode of the camera device is a day-to-day mode, if it is judged that the day-to-night switching condition is met, the current day-to-night mode is switched into the night mode, the first night-to-day switching condition, the second night-to-day switching condition and the day-to-night switching condition are all based on photosensitive values, and judgment is conducted by further combining one or more of camera shooting sensitization and infrared scenes. Through the method and the device, the problem of how to accurately determine the switching of the day and night modes is solved, and the switching accuracy of the day and night modes is improved.

Description

technical field [0001] The present invention relates to the field of image capture, in particular to a day and night mode switching method and device, an imaging device and a storage medium. Background technique [0002] Day and night mode automatic switching is one of the necessary functions of the front-end camera device. The front-end camera device can determine whether the day mode or the night mode is currently used according to factors such as light intensity or image quality in the scene, and automatically switch between day and night modes when it is determined that the mode should change. [0003] Corresponding to different modes, the camera device can be set to use different filters. For example, IRCut filters can be used in day mode to give priority to ensuring the color reproduction of the image; fully transparent filters can be used in night mode to increase the sensitivity of the camera at night. [0004] The timing of day and night mode switching affects the...
