All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; the two elements may be directly connected or indirectly connected through an intermediate medium, or may be communicated with each other inside the two elements, or may be wirelessly connected or wired connected. The specific meanings of the above terms in the present invention can be understood in a specific case to those of ordinary skill in the art.
In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1, one or more embodiments of the present invention provide a method of lamp dimming including, but not limited to, the following steps.
Step S110: an environmental image of a target area is acquired, the environmental image having a first data format, at least one light disposed in the target area.
Specifically, in conjunction with the illustration in fig. 2, a power supply provides power to a Digital Signal Processing (DSP) that is electrically connected to the camera and from which an environmental image of a target area may be obtained, wherein the target area has at least one light (e.g., an LED light).
In one or more embodiments of the present invention, acquiring the environment image of the target area may include, but is not limited to, acquiring the environment image with a Camera in a Preview (Camera Preview) state, the Camera being used for acquiring the environment image.
Specifically, with reference to fig. 3, the camera may be turned on periodically or at regular time, and LOG information (LOG file, LOG) of the camera is read when the camera is in a preview state, so as to obtain an environmental image from the LOG information, thereby reducing the usage time of the camera and saving more energy.
In a specific example of the present invention, the camera sends the acquired image to the DSP, where the image has a first data format, and the first data format may be a BR data format or an RGB data format. The BR data format refers to a common method used when collecting digital images when a Charge Coupled Device (CCD) or a Complementary Metal Oxide Semiconductor (CMOS) device is used as a photosensor. The RGB data format is a color standard in the industry, which obtains various colors by changing three color channels of red (R), green (G) and blue (B) and superimposing them on each other, where RGB represents the colors of the three channels of red, green and blue, and the standard includes almost all colors that can be perceived by human vision, and is one of the most widely used color systems.
Step S120: and performing data format conversion processing on the environment image, and acquiring the current exposure index in the data format conversion processing process.
Specifically, in conjunction with fig. 2 and 3, the data format conversion process may be performed on the environment image by the DSP, and the current exposure index of the image is acquired by a designated Application program (APP).
In one or more embodiments of the present invention, the data format conversion processing of the environment image may include: the environment image is converted from a first data format to a second data format.
For example, in conjunction with fig. 4, the DSP may perform Image Signal Processing (ISP) on the received Image in the first data format (BR data format). The process of processing the image by the ISP may include converting the image in BR data format into an image in RGB data format by AEC, black level correction, dead pixel removal, bayer noise removal, lens screening, bilinear interpolation algorithm, etc., and then obtaining an image in a second data format (e.g., YUV data format) by processing such as auto white balance, color correction, tone mapping, chroma enhancement, skin color enhancement, hardware wavelet denoising, adaptive spatial filter, etc.
In the embodiment, the image in the BR data format which is easy to read by a computer is converted into the YUV data format which is convenient for human eye recognition, so that the image browsing is more convenient.
In one or more embodiments of the present invention, obtaining the current exposure index during the data format conversion process may include: the current exposure index is obtained before the environmental image is updated from the first data format to the second data format.
In one or more embodiments of the present invention, obtaining the current exposure index in the course of performing the data format conversion process includes:
after the process of automatic exposure control is finished, acquiring a current exposure index;
wherein the process of the data format conversion processing includes a process of automatic exposure control.
Specifically, in conjunction with fig. 4, the DSP may be utilized to obtain the current exposure index through the AEC process during the ISP process before the image in BR data format is converted into the image in YUV data format. Wherein, the APP reads LOG information of the AEC through a DSP provided in a Central Processing Unit (CPU) to read a current exposure index from the LOG information.
At least one embodiment of the invention can acquire the current exposure index before the environment image data format is updated to the second data format, for example, the exposure index is acquired before the environment image data format becomes the YUV data format, so that the current exposure index and the corresponding brightness parameter can be determined early, the aim of adjusting the lamp brightness based on the determined brightness parameter can be achieved, and the accuracy of adjusting the lamp brightness can be effectively improved by accelerating the speed of adjusting the lamp brightness. In addition, the AEC process can be utilized to adjust the image into the image with proper brightness, so that the resolution of human eyes on picture details and the identification of targets are met, and the color expression of the image can meet the visual and psychological needs and the indexes of actual engineering.
Step S130: and determining a current brightness parameter corresponding to the current exposure index according to a preset mapping relation, wherein the preset mapping relation is the mapping relation between the exposure index and the brightness parameter.
Specifically, in conjunction with fig. 3, the current luminance parameter (e.g., the actual luminance value) corresponding to the current exposure index may be determined by querying a mapping table that records a mapping relationship (i.e., a preset mapping relationship) between the exposure index and the luminance parameter, where the preset mapping relationship is obtained through a light box luminance test. The exposure index is changed by adjusting the luminance number of the light box, for example, the luminance parameter 1500 corresponds to the exposure index a, the luminance parameter 780 corresponds to the exposure index b, … …; reading the brightness parameter by a brightness meter, and recording the exposure index and the brightness parameter corresponding thereto as
Table 1.
TABLE 1
Step S140: the brightness of the at least one lamp is adjusted based on the current brightness parameter.
Specifically, in one or more embodiments of the present invention, adjusting the brightness of at least one lamp based on the current brightness parameter may include:
comparing the current brightness parameter with the standard brightness parameter to obtain a comparison result;
adjusting a supply current of the lamps based on the comparison result to adjust a brightness of at least one lamp;
the standard brightness parameter is a brightness parameter corresponding to the required ambient brightness.
In the above embodiment, the desired ambient brightness may be set according to a specific application scenario or a preference requirement of an individual, so that the whole lighting environment is more comfortable.
Specifically, in one or more embodiments of the present invention, adjusting the supply current of the lamp based on the comparison result may include:
if the current brightness parameter is greater than the standard brightness parameter, reducing a first percentage of the lamp supply current;
if the current brightness parameter is less than the standard brightness parameter, increasing the power supply current of the lamp by a second percentage;
if the current brightness parameter is equal to the standard brightness parameter, the supply current of the lamp is kept unchanged.
In the above embodiment, the current is adjusted according to the numerical relationship between the brightness parameters respectively corresponding to the actual ambient brightness and the required ambient brightness, so that the brightness of the lamp can be adjusted more accurately.
In one or more embodiments of the present invention, after adjusting the brightness of the at least one lamp based on the current brightness parameter, further comprising:
and returning to the step of acquiring the environment image of the target area.
In the above embodiment, the brightness of the lamp may also be adjusted by multiple steps, so that the brightness adjustment process is more linear, the loss of the lamp is reduced, and discomfort of people due to sudden brightness change is avoided.
Specifically, with reference to fig. 3, the actual brightness value may be compared with a preset standard brightness value (i.e., a standard brightness parameter), and if the actual brightness value is smaller than the preset standard brightness value, the power supply current of the lamp is increased, and if the actual brightness value is larger than the preset standard brightness value, the power supply current of the lamp is decreased.
In one specific example of the invention, in connection with fig. 2, the supply current of the lamp can be adjusted on the basis of the comparison of the actual brightness value X with a preset standard brightness value Y:
if X is larger than Y, the DSP reduces the current to the lamp by 10% through a Pulse Width Modulation (PWM), and after the lamp brightness is stable, the exposure index continues to feed back the current brightness value X until X is equal to Y.
If X is smaller than Y, the DSP increases the current to the lamp by 10% through PWM, and after the lamp brightness is stable, the exposure index continues to feed back the current brightness value X until X is equal to Y.
In one or more embodiments of the present invention, the first percentage and the second percentage may be determined by a difference of the current luminance parameter and the standard luminance parameter.
In the embodiment, the brightness of the lamp is adjusted through the accurate calculation process, so that the lamp is more suitable for the daily life and work needs of people, the brightness adjustment is more accurate, and the loss of electric power can be reduced.
In the foregoing embodiment, the DSP, PWM and camera may be connected via an Inter-Integrated Circuit (I2C), and the I2C bus is a simple, bi-directional two-wire synchronous serial bus. It requires only two wires to transfer information between devices connected to the bus.
In the embodiment, the brightness mapping relation is made by using a camera general AEC algorithm, so that the DSP has a function of reading the current brightness, the brightness of the lamp can be accurately and dynamically adjusted, and the science and technology can help to save energy and reduce emission.
Compared with the prior art that the digital camera photosensitivity quantification regulation (ISO) information is read from the photographed YUV picture and then the brightness mapping relation is deduced reversely, the exposure index can be read in real time in the first module AEC in the ISP processing flow, and compared with the brightness information fed back by other patents, the brightness control method is quicker in brightness regulation, more linear in brightness regulation and capable of reducing discomfort caused by flicker.
