Detailed Description
The present disclosure is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the present disclosure and not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present disclosure are shown in the drawings.
It should be noted that the terms "system" and "network" are often used interchangeably herein in this disclosure. References to "and/or" in embodiments of the present disclosure are intended to "include any and all combinations of one or more of the associated listed items. The terms first, second and the like in the description and in the claims and drawings are used for distinguishing between different objects and not for limiting a particular order.
It should be further noted that, the following embodiments of the present disclosure may be implemented separately or in combination with each other, and the embodiments of the present disclosure are not limited in this regard.
In the following embodiments, optional features and examples are provided in each embodiment at the same time, and the features described in the embodiments may be combined to form multiple alternatives, and each numbered embodiment should not be considered as only one technical solution.
Referring to fig. 1, a flow chart of a method for adjusting brightness of a lamp according to an embodiment of the present disclosure is shown, where the method disclosed in the embodiment of the present disclosure is mainly applicable to a situation that brightness of the lamp is automatically adjusted according to an image captured by a camera on the lamp, for example, the method is applied to a scene where a user learns by using an intelligent desk lamp with a click-to-read function, and the image of a desktop or a book is captured by the camera on the click-to-read desk lamp in the scene, and the current environment brightness is determined according to the image of the desktop or the book, so that brightness of the intelligent desk lamp is adjusted to ensure that the user learns under comfortable light brightness; the method can also be used for determining the ambient brightness of the image shot by the monitoring camera under the monitoring shooting scene, and adjusting the brightness of the infrared lamp of the camera according to the continuous reading of the environment so as to ensure the quality of the image shot by the monitoring camera. The method can be executed by a corresponding lamp brightness adjusting device, and the device can be realized in a software and/or hardware mode and can be configured on a lamp, such as an intelligent click reading desk lamp with a camera or a monitoring camera.
As shown in fig. 1, the method specifically includes the following steps:
s101, acquiring exposure information of an image shot by the camera.
Wherein the exposure information includes at least exposure time and sensitivity. Since the basic information of the image, such as format, size or exposure information, is stored in the image captured by the camera, the exposure time and sensitivity of capturing the image stored in the image can be obtained by performing image recognition on the image captured by the camera. Alternatively, since photographing parameters, such as exposure information, at the time of photographing are also stored in the camera device, the exposure information may also be acquired through a specific interface.
S102, determining a current environment brightness value according to the exposure information.
For example, the ambient brightness value corresponding to the exposure information is determined according to a pre-stored mapping table of the exposure information and the ambient brightness value, wherein the mapping table stores the ambient brightness values corresponding to different exposure time and sensitivity, so that the current ambient brightness value corresponding to the exposure information can be determined only by acquiring the exposure time and the sensitivity of the image.
The mapping table is determined by counting exposure information of images shot by the camera under different environment brightness values. For example, in a light box, a camera is controlled to shoot images under different ambient brightness values, and exposure time and sensitivity corresponding to the images are acquired, wherein the different ambient brightness values are detected by standard light brightness detection equipment, for example, a standard illuminometer is used for measurement, so that a mapping table can be determined according to the different exposure time and sensitivity and the corresponding ambient brightness. Further, in order to ensure the accuracy of the obtained mapping table, the signal-to-noise ratio of the image shot by the camera can be obtained, and the accuracy of the mapping table of the exposure information and the ambient brightness value is determined according to the signal-to-noise ratio. Since the more the noise of the image is, the larger the sensitivity of the corresponding image should be, whether the sensitivity of the image is accurate or not can be determined by the noise in the calculated image, thereby achieving the purpose of verification.
In another alternative embodiment, fitting operation is performed according to the acquired different exposure time and sensitivity and the corresponding ambient brightness, so as to obtain a nonlinear equation of the ambient brightness, the exposure time and the sensitivity, and the brightness of the current environment is calculated directly according to the acquired nonlinear equation by the acquired exposure time and the acquired sensitivity.
S103, comparing the current ambient brightness value with a preset ambient brightness threshold value, and adjusting the brightness of the lamp according to a comparison result.
For example, the brightness of the lamp may be adjusted according to the difference between the current ambient brightness value and the preset ambient brightness threshold. For example, the current ambient brightness value is the same as the preset ambient brightness threshold by either turning up the brightness of the luminaire or turning down the luminaire brightness based on the difference between the current ambient brightness value and the preset ambient brightness threshold.
According to the embodiment of the disclosure, the current environment brightness value is determined according to the exposure information by acquiring the exposure information of the image shot by the camera on the lamp, the current environment brightness value is compared with the preset environment brightness threshold value, and the brightness of the lamp is adjusted according to the comparison result. Therefore, by analyzing the exposure information of the image shot by the camera, the dynamic adjustment of the brightness of the lamp is realized, the adjustment cost is reduced, and the adjustment efficiency is improved.
Referring to fig. 2, a flowchart of another method for adjusting brightness of a lamp according to an embodiment of the disclosure is shown, in order to avoid frequent adjustment of brightness of the lamp, an operation for determining whether adjustment of brightness of the lamp is required is added, and an operation for verifying an adjustment result is added. As shown in fig. 2, the method includes:
s201, acquiring exposure information of an image shot by the camera.
S202, judging whether the exposure information meets a preset condition, and if not, executing S203.
The preset condition is used for indicating that brightness adjustment of the lamp is not needed. Since the exposure information at least includes exposure time and sensitivity, the preset condition at least includes a preset exposure time interval and a preset sensitivity interval corresponding to the exposure time and the sensitivity, respectively; the preset exposure time interval and the preset sensitivity interval are used for representing the range of values of exposure time and sensitivity required for shooting images meeting the requirements of users. Thus, after the exposure time and the sensitivity of the captured image are obtained in S201, it may be determined whether the brightness of the lamp needs to be adjusted by determining whether the exposure time and the sensitivity are within respective preset intervals.
S203, determining the current ambient brightness value according to the exposure information.
S204, comparing the current ambient brightness value with a preset ambient brightness threshold value, and adjusting the brightness of the lamp according to a comparison result.
The preset ambient brightness threshold is an ambient brightness value corresponding to whether the exposure time and the sensitivity are within respective preset intervals. Therefore, if the determined current ambient brightness value is different from the preset ambient brightness threshold value, the current ambient brightness value and the preset ambient brightness threshold value can be the same by adjusting the brightness of the lamp. For example, when the current ambient brightness value is smaller than the preset ambient brightness threshold value, the current ambient brightness may be increased by increasing the brightness of the lamp.
Further, after the brightness of the lamp is adjusted, the exposure information of the image newly shot by the camera is obtained, and whether the exposure information meets the preset condition is judged, so that whether the brightness adjustment of the lamp light is accurate is verified. For example, after adjusting the brightness of the lamp, if the exposure time and the sensitivity of the newly shot image are both within the corresponding preset exposure time interval and preset sensitivity interval, respectively, the brightness adjustment of the lamp is considered to be accurate.
According to the embodiment of the disclosure, whether the brightness of the lamp needs to be adjusted or not is judged by judging whether the exposure time and the light sensitivity of the image shot by the camera on the lamp are in the respective preset intervals, so that frequent adjustment of the brightness of the lamp is avoided, and after the brightness of the lamp is adjusted each time, whether the exposure information of the newly shot image meets the preset conditions or not is judged to verify the accuracy of the adjustment operation.

an acquiring module 301, configured to acquire exposure information of an image captured by the camera;
an ambient brightness calculation module 302, configured to determine a current ambient brightness value according to the exposure information;
and the adjusting module 303 is used for comparing the current ambient brightness value with a preset ambient brightness threshold value and adjusting the brightness of the lamp according to a comparison result.

Therefore, by analyzing the exposure information of the image shot by the camera, the dynamic adjustment of the brightness of the lamp is realized, the adjustment cost is reduced, and the adjustment efficiency is improved.
