The transceiver, which may be used for data transmission with other devices, for example, to send lighting parameter adjustment messages to the smart lamp, may include an antenna, a matching circuit, a modem, and the like. The image detection means may be a camera or the like. The terminal may further include an audio output part and an audio input part, etc. The audio output component may be a speaker, headphones, or the like. The audio input means may be a microphone or the like.
The process flow shown in fig. 1 will be described in detail below with reference to the embodiments, and the contents may be as follows:
in step 101, after receiving a photographing instruction, according to a preset detection period, calculating a photographing exposure value according to a photographing parameter to be used and a detected light intensity of a photographing object.
The photographing parameters can be obtained by automatically setting the image acquisition equipment according to the current environment, and under the condition, the image acquisition equipment is in a full-automatic mode; the photographing parameters can also be obtained by manually setting one part by a user and calculating the other part by the image acquisition equipment, and in this case, the image acquisition equipment is in a semi-automatic mode; the photographing parameters may also be set manually by the user, in which case the image capturing device is in a purely manual mode.
In the implementation, when the user is in the indoor that has the intelligent lamp, when wanting to use image acquisition equipment to shoot, the user can open image acquisition equipment, and through image acquisition equipment's screen, the user can see the image that the camera can be shot. The image acquisition equipment is adjusted, and when the user feels that the image that can shoot accords with the mind of the user, the user can click the option of shooing.
When the image acquisition equipment is in a full-automatic mode or a semi-automatic mode, the image acquisition equipment acquires current photographing parameters such as an aperture value, a shutter speed, sensitivity and the like according to a preset detection period after receiving a photographing instruction. Then, the image pickup apparatus may detect the light intensity of the photographic subject according to the current photometry manner. The light measurement method may be spot light measurement, average light measurement, center-weighted average light measurement, or the like. When the light measuring mode is point light measuring, the light intensity acquired by the image acquisition equipment is the light intensity of one point of the shooting object; when the light measuring mode is average light measuring, the light intensity obtained by the image acquisition equipment is the average value of the light intensity of each point which can be shot; when the light measuring mode is the central key point average light measuring, the light intensity acquired by the image acquisition equipment is the average value of the light intensity of each point in the central key point area.
The image acquisition equipment can calculate the exposure value of the photo according to the acquired photo parameters and the acquired light intensity, wherein the exposure value is the actual exposure value under the current light intensity.
In step 102, if the difference between the preset target exposure value and the exposure value is greater than the preset difference threshold, a light-emitting parameter adjustment message is sent to the smart lamp, where the light-emitting parameter adjustment message is used to instruct the smart lamp to adjust the light-emitting brightness by a preset value.
Alternatively, in an actual scene, when the user adjusts the photographing parameter so that the difference between the exposure and the preset target exposure is greater than the preset difference threshold, it is likely that the user intentionally overexposes the smart lamp for pursuing artistic effect, and in this case, the user does not want the light emission brightness of the smart lamp to be adjusted. Therefore, when this situation is eliminated, the corresponding processing of step 102 may be as follows: and if the difference value of the preset target exposure value minus the exposure value is greater than the preset difference threshold value, sending a light-emitting parameter adjusting message to the intelligent lamp, wherein the light-emitting parameter adjusting message is used for indicating the intelligent lamp to improve the light-emitting brightness by a preset value.
In implementation, after the exposure value is calculated according to the steps, the image acquisition equipment acquires a preset target exposure value. The target exposure value is obtained by a technician through a plurality of tests, so that the brightness of the shot picture is the best under the target exposure value. Then, the image acquisition device calculates a difference value of the target exposure value minus the calculated exposure value, and compares the difference value with a preset difference threshold value. If the calculated difference is larger than the preset difference threshold, it indicates that the exposure value of the image acquisition device is insufficient under the current light intensity, that is, the current light intensity is insufficient, and the picture taken under the light intensity may be dim.
Therefore, as shown in fig. 2, the image capturing device will send a lighting parameter adjustment message to the smart lamp, where the lighting parameter adjustment message is used to instruct the smart lamp to increase the lighting brightness by a preset value. And after receiving the light-emitting parameter adjusting message, the intelligent lamp improves the light-emitting brightness by a preset value. The preset value may be a smaller unit, for example, the brightness of the smart lamp is set to 0-100 level from turning off the lamp to full brightness, and after receiving the lighting parameter adjustment message, the smart lamp increases the lighting brightness by 1 level.
After the intelligent lamp is adjusted, the image acquisition equipment acquires the photographing parameters to be used and the current light intensity again according to a preset detection period, calculates an exposure value according to the acquired photographing parameters and light intensity, and compares the exposure value with a target exposure value. If the difference value of the target exposure value minus the exposure value is larger than the preset difference value threshold value, the image acquisition equipment sends a light-emitting parameter adjustment message to the intelligent lamp again, and the intelligent lamp increases the light-emitting brightness again by the preset value according to the received light-emitting parameter adjustment message. And repeating the steps until the difference value of the target exposure value minus the exposure value is less than or equal to the preset difference value threshold, and stopping sending the light-emitting parameter adjusting message to the intelligent lamp by the image acquisition equipment.
Optionally, in the same scene, there may be two or more than two intelligent lamps in a connection state with the same image capturing device, in this case, the corresponding processing may be as follows: and determining a target intelligent lamp closest to the equipment among the plurality of intelligent lamps, and sending a light-emitting parameter adjusting message to the target intelligent lamp.
In the above steps, the image acquisition device and the intelligent lamp can be connected through modes such as bluetooth, WIFI, honeycomb network and the like. If more than two intelligent lamps are arranged in the same scene and the more than two intelligent lamps are connected with the same image acquisition device, the relative position between the image acquisition device and each intelligent lamp is determined in a GPS mode and the like, and how to adjust the light-emitting parameters of the intelligent lamps is determined according to the relative position. For example, as shown in fig. 3, the distance between the image capturing device and each smart lamp is determined, the smart lamp closest to the distance is determined as the target smart lamp, a lighting parameter adjustment message is sent to the target smart lamp, and only the lighting parameter of the smart lamp is adjusted. In addition, at least one smart lamp within a preset distance may also be determined as a target smart lamp, as shown in fig. 4, while adjusting the lighting parameters of the smart lamps, and the disclosure is not limited herein.
In step 103, if the difference between the target exposure value and the exposure value is less than or equal to the preset difference threshold, the image is photographed based on the photographing parameters and the photographing process is ended.
Alternatively, in an actual scene, when the user adjusts the photographing parameter so that the difference between the exposure and the preset target exposure is greater than the preset difference threshold, it is likely that the user intentionally overexposes the smart lamp for pursuing artistic effect, and in this case, the user does not want the light emission brightness of the smart lamp to be adjusted. Therefore, when this situation is eliminated, the corresponding processing of step 103 may be as follows: and if the difference value of the target exposure value minus the exposure value is less than or equal to the preset difference threshold value, shooting the image based on the shooting parameters and finishing the shooting processing.
In an implementation, when the image capturing device compares the calculated exposure value with the target exposure value, if the difference between the target exposure value and the exposure value is smaller than or equal to the preset difference threshold, it indicates that the exposure value of the image capturing device is sufficient at the current light intensity, that is, the current light intensity is sufficient, and the picture taken at the light intensity is brighter. Therefore, the image capturing apparatus can capture an image based on the current photographing parameter and the current light intensity, and end the photographing process.
Optionally, when determining whether the lighting parameter of the smart lamp needs to be adjusted, the influence of the sensitivity in the photographing parameter on the photographed picture may also be considered, and the corresponding processing may be as follows: and if the difference value of the target exposure value minus the exposure value is less than or equal to a preset difference threshold value and the sensitivity in the photographing parameters is less than or equal to a preset sensitivity threshold value, photographing the image based on the photographing parameters and ending the photographing process.
In implementation, when the image capturing apparatus is in the fully automatic mode, the image capturing apparatus acquires a preset target exposure and a preset sensitivity threshold, and then compares the calculated exposure value with the target exposure value. If the difference between the target exposure value and the exposure value is smaller than or equal to the preset difference threshold and the sensitivity in the photographing parameters is smaller than the preset sensitivity threshold, the current ambient light intensity can make the photographed picture brighter and the current sensitivity can make the photographed picture clearer, so that photographing processing can be performed based on the photographing parameters.
If the difference between the target exposure value and the exposure value is smaller than or equal to the preset difference threshold and the sensitivity in the photographing parameters is greater than the preset sensitivity threshold, it is indicated that the current ambient light intensity can make the photographed picture brighter, but the current sensitivity may make the photographed picture more noisy, resulting in unclear photographed picture. Therefore, in this case, the image capture device sends a lighting parameter adjustment message to the smart lamp, causing the light intensity of the smart lamp to increase. At this time, in order to ensure that the exposure value is within the normal range, the image acquisition device automatically reduces the sensitivity and continuously increases the light intensity of the intelligent lamp, so that the sensitivity is continuously reduced until the sensitivity is less than or equal to a preset sensitivity threshold, the image acquisition device stops sending the light-emitting parameter adjustment message to the intelligent lamp, shoots an image based on the current shooting parameter and the current light intensity, and ends the shooting process.
Optionally, when determining whether to adjust the light emitting parameter of the smart lamp, it may also be considered that when the shutter speed is relatively high, the handheld image capturing device takes the influence on the quality of the taken picture, and the corresponding processing may be as follows: and if the difference value of the target exposure value minus the exposure value is less than or equal to a preset difference threshold value, and the shutter speed in the photographing parameters is greater than a preset shutter speed threshold value, photographing the image based on the photographing parameters and ending the photographing process.
In implementation, when the image capturing device is in the fully automatic mode, the image capturing device obtains a preset target exposure and a preset shutter speed threshold, and then compares the calculated exposure value with the target exposure value. If the difference between the target exposure value and the exposure value is smaller than or equal to the preset difference threshold value and the shutter speed in the photographing parameters is larger than the preset shutter speed threshold value, the current ambient light intensity can enable the photographed picture to be brighter, and the image acquisition equipment has little influence on the quality of the photographed picture no matter whether the image acquisition equipment is in a handheld state or not, so that photographing processing can be performed based on the current photographing parameters and the current light intensity.
If the difference between the target exposure value and the exposure value is smaller than or equal to the preset difference threshold value, and the shutter speed in the photographing parameters is smaller than or equal to the preset shutter speed threshold value, it is shown that the current ambient light intensity can make the photographed picture brighter, but the shutter speed is lower, and the quality of the photographed picture may be affected if the image acquisition device is in a handheld photographing state. Therefore, whether the image pickup apparatus is in a handheld shooting state is detected. If the image acquisition equipment is in a handheld shooting state, the image acquisition equipment sends a light-emitting parameter adjustment message to the intelligent lamp, so that the light-emitting brightness of the intelligent lamp is continuously increased. Under the condition, in order to ensure that the exposure value is in a normal range, the image acquisition equipment can automatically adjust the photographing parameters, so that the aperture value is reduced, and the shutter speed is increased. And stopping sending a light-emitting parameter adjusting message to the intelligent lamp by the image acquisition equipment until the shutter speed is greater than a preset shutter speed threshold value, shooting the image based on the current shooting parameter and the current light intensity, and finishing the shooting processing.
If the image acquisition equipment is not in a handheld shooting state, the quality of a shot picture cannot be reduced due to the fact that the shutter speed is low, and therefore shooting processing is conducted based on the current shooting parameters and the current light intensity.
In the above steps, there are many methods for detecting whether the image capturing device is in the handheld state, for example, the moving speed of the image capturing device may be detected according to a gyroscope sensor in the image capturing device, and if the moving speed of the image capturing device is greater than a preset moving speed threshold of the image capturing device, it is determined that the image capturing device is in the handheld state. If the image acquisition equipment is a camera, a detection switch can be arranged at a bracket interface of the camera, whether the camera is provided with a bracket or not can be detected, and if the camera is not provided with the bracket, the camera is determined to be in a handheld state.
Optionally, besides the above-mentioned adjusting of the luminous brightness of the smart lamp, the color temperature of the smart lamp may be adjusted according to the user's requirement, and the corresponding steps may be as follows: after receiving the photographing instruction, if the ambient light color temperature value is not equal to the color temperature value in the photographing parameter, determining a difference value between the ambient light color temperature value and the color temperature value in the photographing parameter to obtain a color temperature adjustment value. And sending a light-emitting parameter adjusting message carrying the color temperature adjusting value to the intelligent lamp, wherein the light-emitting parameter adjusting message is also used for indicating the intelligent lamp to adjust the light-emitting color temperature value based on the color temperature adjusting value.
In implementation, the user may turn on a semi-automatic mode or a purely manual mode of the image capturing device, in which both modes the user may manually set the color temperature value. When the user feels that the images which can be shot accord with the mind of the user, the user can click the shooting option. After receiving the shooting instruction, the image acquisition device can acquire the current shooting parameters, extract the color temperature value therein, and then acquire the current ambient light color temperature value. And comparing the color temperature value in the photographing parameter with the ambient light color temperature value, if the color temperature value in the photographing parameter is not equal to the ambient light color temperature value, calculating the difference value between the ambient light color temperature value and the color temperature value in the photographing parameter, and determining the difference value as the color temperature adjustment value.
Then, the image acquisition equipment adds the color temperature adjustment value to a light-emitting parameter adjustment message, and sends the light-emitting parameter adjustment message carrying the color temperature adjustment value to the intelligent lamp. And after receiving the light-emitting parameter adjusting message, the intelligent lamp analyzes the message, extracts the color temperature adjusting value in the message, and adjusts the light-emitting color temperature value according to the color temperature adjusting value. For example, as shown in fig. 5, the user manually sets the color temperature value to 5400K, that is, wants to take a picture of the ambient light color temperature value of 5400K, and after the user clicks the shooting option, the image capturing device obtains the current ambient light color temperature value of 2900K, and calculates the color temperature adjustment value to be 2500K. Then, the image acquisition equipment sends a light-emitting parameter adjustment message to the intelligent lamp, and the intelligent lamp increases the light-emitting color temperature value by 2500K after receiving the light-emitting parameter adjustment message.
In the above step, when the image capturing device sends the lighting parameter adjusting message to the smart lamp, the lighting parameter adjusting message may be used to adjust the lighting brightness of the smart lamp, may also be used to adjust the lighting color temperature value of the smart lamp, and may also be used to simultaneously adjust the lighting brightness and the lighting color temperature value of the smart lamp, which is not limited in this disclosure.
Optionally, in addition to the manner in which the photographing instruction in the above step triggers obtaining of the photographing parameter and calculating of the exposure value, there may be other triggering manners, and the corresponding processing may be as follows: and after a preset trigger event is detected, calculating a shot exposure value according to a preset detection period and the to-be-used shooting parameter and the detected light intensity of the shot object.
