To address this problem, the image processor of the video camera in the prior art can gradually adjust the image signal processing parameter set in a stepwise manner until the video image gradually returns to normal. However, in the above method, the ISP parameter set for restoring the image to normal is gradually approached by using a step adjustment method, and in the step adjustment process, the video image is still not ideal.
In view of the above problems, an embodiment of the present invention provides a method for determining a shooting parameter, where a terminal device determines, according to environmental data of an environment where the terminal device is located, whether at least one optical accessory of the terminal device needs to be switched to a target state, if so, at least one of the target state of the at least one optical accessory, a current exposure of the terminal device, and a current time is obtained, and according to at least one of the target state of the at least one optical accessory, the current exposure, and the current time, a pre-obtained image signal processing ISP parameter set database is queried, a target ISP parameter set of the terminal device is obtained, and a shooting parameter of the terminal device is determined according to the target ISP parameter set. The shooting parameters of the terminal equipment are adjusted according to the state of the optical accessory, so that the phenomenon of overexposure or underexposure of the video image caused by the state change of the optical accessory is avoided, and the quality of the video image is improved.
The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 1 is a first flowchart illustrating a method for determining a shooting parameter according to an embodiment of the present invention. The embodiment of the invention provides a method for determining shooting parameters, which can be executed by any device for executing the method for determining shooting parameters, and the device can be realized by software and/or hardware. In this embodiment, the apparatus may be integrated in a terminal device, and the terminal device may be a mobile phone, a computer, a video camera, and the like having a shooting function, which is not limited by the present solution. As shown in fig. 1, a method for shooting parameters according to an embodiment of the present invention includes the following steps:
step 101, judging whether at least one optical accessory of the terminal equipment needs to be switched to a target state according to the environment data of the environment where the terminal equipment is located.
The terminal equipment has a shooting function, and optical accessories can be arranged on the terminal equipment and comprise an infrared light supplementing lamp, a visible light supplementing lamp, an illuminating lamp, a switchable filter light sheet and the like. The optical accessory is used for providing auxiliary light when shooting under the condition of lacking light so as to shoot a reasonable image.
The target state of the optical accessory includes an on state or an off state.
In a possible implementation, the environmental data of terminal equipment place environment includes the light intensity of terminal equipment place environment, if the light intensity of terminal equipment place environment is less than preset light intensity, and current terminal equipment's light is not opened, then judge and to switch into the on-state with the light, perhaps, current terminal equipment's infrared light filling lamp is not opened, obtain more reasonable image for the shooting, then judge and to switch into the on-state with infrared light filling lamp, specific need opens which kind of optical accessories, can be according to actual conditions and decide, this scheme is all not the restriction to the quantity and the kind that need switch to the optical accessories of target state.
In another possible implementation manner, if the illumination lamp of the current terminal device is turned on and the light intensity of the environment where the terminal device is located is greater than the preset light intensity, it is determined that the illumination lamp can be switched to the off state, so as to reduce power consumption of the terminal device.
And 102, if so, acquiring at least one of a target state of at least one optical accessory, a current exposure of the terminal equipment and a current moment.
It should be noted that the shooting function of the terminal device may be affected by the natural optical environment of weather (sunny day or cloudy day), but because the terminal device such as a video camera is inconvenient to acquire the current weather condition, the current automatic exposure of the terminal device is used to indirectly measure the current weather condition, specifically, because the automatic exposure of the terminal device may be affected by the current weather condition, when the terminal device is used to shoot, the terminal device itself may adaptively adjust the automatic exposure according to the current weather condition, so the current exposure of the terminal device may be used to indirectly measure the current weather condition.
Optionally, the current time is a time of day, including morning, noon, and evening.
Specifically, if it is determined that at least one optical accessory of the terminal device needs to be switched to the target state, at least one of the target state of the at least one optical accessory, the current exposure of the terminal device, and the current time is obtained.
Step 103, inquiring a pre-acquired image signal processing ISP parameter set database according to at least one of the target state, the current exposure and the current time of at least one optical accessory, and acquiring a target ISP parameter set of the terminal equipment.
The ISP parameter set database is a set of a plurality of ISP parameter sets determined according to the exposure of the terminal equipment and the state of at least one optical accessory under a plurality of different historical moments.
Optionally, the ISP parameter set includes an automatic exposure parameter, a gain value, and a noise reduction parameter, and when shooting is performed, a reasonable ISP parameter set is set to obtain a reasonable and normal image.
Optionally, in the ISP parameter set database, at least one of the time, the exposure amount of the terminal device, and the state of at least one optical accessory may be in a one-to-one mapping relationship with the ISP parameter set, where the mapping relationship may be in a form of a table, a text form, or the like, and this is not limited in this embodiment.
It should be noted that, because the optical accessory may cause instantaneous overexposure or underexposure when opened and closed, in the prior art, the ISP parameter set is adjusted in a stepping manner and needs to be adjusted in a very short time, so that the adjustment effect is poor and the image quality is poor.
Then, according to at least one of the target state, the current exposure and the current time of at least one optical accessory, inquiring a pre-acquired image signal processing ISP parameter set database to obtain an ISP parameter set consistent with at least one of the target state, the current exposure and the current time of at least one optical accessory, wherein the ISP parameter set is a target ISP parameter set of the terminal equipment.
And step 104, when at least one optical accessory is switched to the target state, determining shooting parameters of the terminal equipment according to the target ISP parameter set.
And after the target ISP parameter set of the terminal equipment is acquired, when the state of the optical accessory is switched to the target state, taking the target ISP parameter set as a shooting parameter of the terminal equipment. The ISP parameter set can be adaptively adjusted along with the change of the state of the optical accessory, thereby avoiding the phenomenon of overexposure or underexposure of the image caused by the change of the state of the optical accessory and improving the quality of the video image.
The method for determining shooting parameters provided in this embodiment determines, according to environmental data of an environment where a terminal device is located, whether at least one optical accessory of the terminal device needs to be switched to a target state, where the target state includes an on state or an off state, if so, at least one of the target state of the at least one optical accessory, a current exposure amount of the terminal device, and a current time is obtained, and according to at least one of the target state of the at least one optical accessory, the current exposure amount, and the current time, a pre-obtained image signal processing ISP parameter set database is queried to obtain a target ISP parameter set of the terminal device, where the ISP parameter set database is a set of a plurality of ISP parameter sets determined according to the exposure amounts of the terminal device and the state of the at least one optical accessory at a plurality of different historical times, and when the at least one optical accessory is switched to the target, and determining the shooting parameters of the terminal equipment according to the target ISP parameter set. The method for determining the shooting parameters can adjust the shooting parameters of the terminal equipment according to the state of the optical accessory, thereby avoiding the overexposure or underexposure phenomenon of the video image caused by the state change of the optical accessory and improving the quality of the video image.
Fig. 2 is a schematic flowchart of a second method for determining shooting parameters according to an embodiment of the present invention, where this embodiment describes in detail a specific implementation process of step 103 on the basis of the embodiment of fig. 1, and as shown in fig. 2, the method includes:
step 201, obtaining a current state of at least one optical accessory.
The current state of the optical accessory includes an on state or an off state.
Step 202, according to at least one of the target state of at least one optical accessory, the current time of the current exposure and the current state of at least one optical accessory, querying a pre-acquired ISP parameter set database to acquire a target ISP parameter set.
The terminal equipment can acquire the current state of at least one optical accessory, and query the ISP parameter set database acquired in advance according to at least one of the target state of at least one optical accessory, the current moment of the current exposure and the current state of at least one optical accessory to acquire the target ISP parameter set.
Optionally, in the ISP parameter set database, at least one of time, an exposure amount of the terminal device, a target state of different optical accessories, and a current state of different optical accessories may be in a one-to-one mapping relationship with the ISP parameter set, where the mapping relationship may be in a form of a table, a text form, or the like, and this is not limited in this embodiment.
In a possible implementation manner, the terminal device may perform two queries to obtain the target ISP parameter set, and first query the ISP parameter set database obtained in advance according to the current exposure, the current time, and the current state of the at least one optical accessory. Specifically, an ISP parameter set is obtained, where a difference between a current exposure amount and an exposure amount in the ISP parameter set database is within a first preset range, a difference between a current time and a time in the ISP parameter set database is within a second preset range, and a current state of at least one optical accessory is the same as a state of the optical accessory in the ISP parameter set database, where the ISP parameter set is an initial ISP parameter set. The first preset range and the second preset range may be selected according to experiments or experiences, and the scheme is not limited to this.
Next, a set of target ISP parameters is determined in the initial set of ISP parameters based on the target state of the at least one optical accessory. Specifically, the target state of at least one optical accessory is used as a search condition, and the initial ISP parameter set is queried to obtain a target ISP parameter set.
The present embodiment will be specifically described below using a specific example.
Assuming a steady state set of ISP parameters can be expressed as:
Pisp＝F(T,W,La,Lb… …) function (1)
Wherein Pisp represents the ISP parameter set in a certain stable state;
t represents the time of day;
w represents the current weather;
Laindicating the state of the optical accessory a (including the current state and the target state);
Lbindicating the state (including the current state and the target state) of the optical accessory b.
Since a terminal device such as a video camera is inconvenient to acquire the current weather condition, the current weather condition is indirectly measured by the current automatic exposure of the terminal device, and the above function can be expressed as:
Pisp＝F(T,A,La,Lb… …) function (2)
A represents the exposure amount of the camera.
For simplicity, it is assumed that only one optical accessory a is provided on the terminal device, such as: the filter, then the function (2) can be expressed as:
Pisp＝F(T,A,La) Function formula (3)
From this it can be determined when T, A, LaWith a certain value, the Pisp parameter set is determined. Assume that in the last few days, every day T is given LaThe camera is shown with the same optical attachment status, and the weather conditions substituted by a are similar, then the corresponding video ISP parameter sets should be similar or identical.
Because the ISP parameter set database records a plurality of ISP parameter set sets determined by the exposure of the terminal equipment and the target states of a plurality of optical accessories at different historical moments, when the current optical accessory state changes, the ISP parameter set database is searched to match the similar T value, the similar A value and the similar L valueaThe state values are the same, if the difference value of T in the same day is found to be within a second preset range, the difference value of A is within a first preset rangeWithin a range of LaEqual to the ISP parameter set Pisp in the target state, which is the target ISP parameter set.
In the method for determining shooting parameters provided in this embodiment, the target ISP parameter set is obtained by obtaining the current state of at least one optical accessory, and querying the ISP parameter set database obtained in advance according to at least one of the target state of at least one optical accessory, the current time of the current exposure, and the current state of at least one optical accessory. The target ISP parameter set acquired by the embodiment is acquired according to the state of the optical accessory, so that the phenomenon of overexposure or underexposure of the video image caused by the state change of the optical accessory is avoided, and the quality of the video image is improved.

step 301, acquiring the exposure and the state of at least one optical accessory of the terminal device at a plurality of different historical moments.
Step 302, determining an ISP parameter set at each historical time based on the exposure at each historical time and the state of the at least one optical accessory.
The state of the optical accessory comprises a current state and a target state of the optical accessory, wherein the current state and the target state comprise an on state or an off state, the terminal equipment acquires the automatic exposure amount and the state of at least one optical accessory at a plurality of different historical moments, and determines an ISP parameter set at each historical moment according to the exposure amount and the state of at least one optical accessory at each historical moment, wherein the ISP parameter set is an ISP parameter set which enables an image to be best shot at the historical moment, the exposure amount and the state of the optical accessory.
The ISP parameter set includes auto exposure parameters, gain values, noise reduction parameters.
And step 303, acquiring an ISP parameter set database according to the ISP parameter sets at each historical moment.
In one possible implementation manner, the state of at least one optical accessory at each historical time and the mapping relation between the exposure at each historical time and the ISP parameter set at each historical time are established, and the ISP parameter set database is obtained. The mapping relation can be in the form of a table or a text, and the scheme does not limit the mapping relation.
Optionally, the terminal device is a video camera.
The key point of the scheme is that the ISP parameter sets in the ISP parameter set database in the scheme are determined in a stepping mode within necessary time, and when the picture is actually shot, the best ISP parameter set is searched according to searching conditions without using a stepping mode for adjustment, so that the picture quality is improved.
In the method for determining shooting parameters provided by this embodiment, the exposure amount and the state of at least one optical accessory of the terminal device at different historical times are obtained, the ISP parameter set at each historical time is determined according to the exposure amount and the state of at least one optical accessory at each historical time, and the ISP parameter set database is obtained according to the ISP parameter set at each historical time. By acquiring the ISP parameter set database in advance, the optimal ISP parameter set can be searched according to the searching condition during actual shooting, and the ISP parameter set does not need to be adjusted in a stepping mode, so that the image quality is improved.
