Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
In order to better understand the technical solution of the present application, the relevant contents of exposure are briefly described here, and fig. 1 is a schematic diagram of an exposure mechanism provided in an embodiment of the present invention. Referring to fig. 1, with the change of the ambient light illumination, the exposure parameters of the image capturing apparatus may adjust corresponding parameters in stages to ensure that the brightness of the captured image remains stable. Generally, when the illuminance is reduced, parameters that can change the amount of light entering, such as the shutter and the fill-in lamp, are preferentially adjusted without introducing noise too early, and when the two parameters are adjusted to the maximum, the gain adjustment is further opened.
The exposure mechanism of the camera is the core of controlling the brightness of the image pickup picture, and the image pickup equipment is required to present stable image pickup picture brightness under various environments. The exposure mechanism determines a default shooting picture brightness tolerance interval, and the shooting picture brightness is required to be always kept in the interval; if the brightness of the shot picture is not in the interval, the shot picture is adjusted by means of a shutter, a fill-in light, gain and the like for an exposure mechanism until the brightness of the shot picture meets the interval requirement. Especially, after the light supplement lamp is turned on, the light supplement lamp can adjust the brightness of the light supplement lamp according to the brightness of the picture until the brightness of the shooting picture meets the interval requirement. Based on above-mentioned analysis, this application scheme mainly solves and easily receives self light filling lamp influence in the stage that the environment becomes bright suddenly, the problem that the deviation appears when leading to the picture to judge ambient brightness, mainly uses the light filling lamp to carry out the light filling stage promptly, solves the light filling lamp of making a video recording and to camera equipment's the influence of making a video recording.
Fig. 2 is a flowchart of an image capturing method provided in an embodiment of the present invention. The embodiment of the invention can be suitable for the condition that the camera shooting equipment shoots in a small scene or a strong-reflection environment, in particular to the condition that a light supplement lamp of the camera shooting equipment is frequently adjusted due to the problem of picture brightness. The method can be executed by a camera device, which can be realized in a software and/or hardware manner and integrated on any camera equipment with network communication function. As shown in fig. 2, the image capturing method provided in the embodiment of the present invention specifically includes the following steps:
s210, in the shooting process, if the number of times of continuous brightness adjustment of the shooting fill-in light is detected to be larger than or equal to a preset number threshold, adjusting a default shooting picture brightness tolerance interval according to the brightness of the current shooting picture to obtain a new shooting picture brightness tolerance interval.
In the present embodiment, the image pickup apparatus of the present application may refer to a camera that supports output of a color picture on a day-night basis, such as a full-color camera in particular. The camera shooting device is provided with at least one visible light supplementary lighting lamp, which is called as a camera shooting supplementary lighting lamp. In the environment of low illuminance, when camera equipment made a video recording, camera equipment's the light filling lamp of making a video recording can be opened and carry out the light filling. The captured picture refers to a captured picture obtained when the camera captures the surrounding environment during image capturing, or refers to an environmental picture that can be captured by the imaging lens of the imaging apparatus.
In the present embodiment, the imaging screen luminance tolerance section refers to a section range of luminance of an imaging screen required by the imaging apparatus during imaging. The default shooting picture brightness tolerance interval is a self-defined shooting picture brightness tolerance interval when the shooting equipment is initialized, or is a shooting picture brightness tolerance interval required by the shooting equipment in an environment of normal light illumination. In the stage of supplementing light by using the light supplementing lamp, if the brightness of a shooting picture of the shooting equipment is within the default brightness tolerance interval, the brightness of the shooting picture meets the requirement, and the shooting light supplementing lamp cannot adjust the brightness; otherwise, the deviation of the brightness of the shooting picture is indicated, and the shooting light supplement lamp can be used for brightness adjustment.
In this embodiment, after the camera turns on the camera shooting fill-in light in the camera shooting process, if the camera shooting device detects that the brightness of the camera shooting picture has deviation, the camera shooting fill-in light can adjust the brightness according to the default camera shooting picture brightness tolerance interval to ensure that the camera shooting picture can be kept in the default camera shooting picture brightness tolerance interval. Therefore, according to the light supplement mechanism of the camera shooting light supplement lamp, if the brightness of the camera shooting picture is not qualified all the time, the brightness of the camera shooting light supplement lamp can be continuously adjusted all the time, the operation of continuously adjusting the brightness can be recorded as the continuous brightness adjustment operation, so that the brightness of the camera shooting picture can continuously fluctuate and change, and the camera shooting picture can flicker unlimitedly in the camera shooting process. Optionally, the adjusting of the brightness includes brightness change caused by turning on and off the camera light supplement lamp, and brightness change caused by increasing or decreasing the brightness of the light supplement lamp after turning on the camera light supplement lamp. In the following, brightness adjustment in some cases will be exemplified, which will cause the brightness of the image pickup screen of the image pickup apparatus to be always unsatisfactory.
Illustratively, as the surrounding environment becomes dark, the full-color camera turns on the visible light supplementary lamp and adjusts the brightness after judging that the scene illumination is reduced. In some small scenes or environments with strong light reflection, especially some narrow indoor spaces (such as small storerooms), the camera shooting light supplement lamp carried by the camera shooting equipment can reflect light strongly, and once the camera shooting light supplement lamp is turned on, the light of the surrounding environment instantly becomes sufficient or even becomes very high. At this time, the full-color camera may determine that the illuminance of the surrounding environment is sufficient (actually, the surrounding light is sufficient only instantaneously), and turn off the camera light supplement lamp to stop light supplement, so that the surrounding environment becomes very dark instantaneously, and the camera light supplement lamp needs to be turned on again to supplement light. So relapse, lead to making a video recording the light filling lamp and can open repeatedly and close the operation to after opening the light filling lamp of making a video recording, the light filling lamp of making a video recording also can adjust luminance in succession incessantly, and above-mentioned continuous adjustment operation all leads to the scintillation problem of the picture of making a video recording in-process appearance.
Based on the above analysis, after the camera shooting light supplement lamp is turned on, when the camera shooting light supplement lamp adjusts the brightness, the number of times of brightness adjustment of the camera shooting light supplement lamp needs to be limited, and once the number of times of continuous brightness adjustment of the camera shooting light supplement lamp is detected to reach a preset number threshold, it is considered that the continuous brightness adjustment operation of the camera shooting light supplement lamp can obviously affect the fluctuation of the camera shooting picture (i.e. the camera shooting picture can obviously flicker). At this time, the brightness of the current shooting picture of the shooting device can be determined, and then the default shooting picture brightness tolerance interval is dynamically adjusted according to the brightness of the current shooting picture, so as to obtain a new shooting picture brightness tolerance interval.
In the embodiment, the brightness is adjusted at intervals by considering the shooting fill-in light, so that only a shooting picture is slowly changed, and a high-frequency flicker phenomenon of the shooting picture is not caused. Therefore, when the number of times of brightness continuous reading adjustment of the camera shooting fill-in light is counted, the counted number of times of brightness continuous reading adjustment is not the number of times of brightness interval adjustment. Optionally, the continuous brightness adjustment in the present application refers to that the brightness of the camera light supplement lamp is continuously adjusted, and the frequency of each brightness adjustment is higher than a preset frequency threshold or the time interval of each brightness adjustment is smaller than a preset threshold. Optionally, the number of times of continuously adjusting the brightness refers to the number of times of continuously increasing the brightness of the camera light supplement lamp; or the number of times the brightness is continuously decreased; or continuously executing the adjustment times of reducing the brightness, increasing the brightness, continuing to reduce the brightness and repeating the reduction.
In an optional example, the continuous brightness adjustment refers to a brightness adjustment operation in which, in the process of adjusting the camera supplementary lighting from one brightness to another brightness, a time interval between corresponding time points of two adjacent brightnesses is smaller than a preset time threshold. In other words, in the process of adjusting the camera supplementary lighting from one brightness to another brightness, if the difference between the time points corresponding to the two brightnesses is smaller than the preset time threshold, the time interval between the two brightnesses is very small, and the camera supplementary lighting performs high-frequency brightness adjustment, then the brightness adjustment is recorded as one-time brightness continuous adjustment. Optionally, for multiple continuous brightness adjustments, the smaller the time interval between the time points corresponding to two brightnesses in each continuous brightness adjustment, the higher the frequency of continuous brightness adjustment operation of the camera light supplement lamp, the more serious the flicker of the image; conversely, the lower the frequency of the continuous adjustment operation of the brightness of the camera fill-in light, the less flickering the picture is caused.
In this embodiment, the section range of the new imaging screen brightness tolerance section optionally includes the section range of the default imaging screen brightness tolerance section. Optionally, the current shooting picture refers to a picture of the surrounding environment obtained by shooting through a shooting lens of the shooting device after it is detected that the number of times of continuous adjustment of the brightness of the shooting fill-in light is greater than or equal to a preset number threshold.
And S220, controlling the shooting light supplement lamp according to the new shooting picture brightness tolerance interval, and continuing to carry out shooting operation.
In this embodiment, a new shooting screen brightness tolerance interval can be obtained by dynamically adjusting the default shooting screen brightness tolerance interval. Therefore, in the shooting process, when the shooting light supplement lamp of the shooting equipment is used for supplementing light, the brightness can be adjusted according to the brightness tolerance interval of the new shooting picture.
In this embodiment, since the new captured image brightness tolerance interval is determined by the brightness of the captured image of the camera, it can be ensured that the brightness of the captured image in a period of time will be kept within the new captured image brightness tolerance interval. Since the shooting fill-in light of the shooting equipment is filled in according to the new shooting picture brightness tolerance interval, since the brightness of the shooting picture is already in the new shooting picture brightness tolerance interval, the shooting fill-in light does not need to continue the brightness adjustment operation as long as the brightness of the shooting fill-in light is kept unchanged. Therefore, the situation that the shooting picture flickers in the shooting process is restrained, and the shooting equipment can normally shoot the image.
The embodiment of the invention provides a shooting scheme, in the shooting process, when the brightness of a shooting picture of shooting equipment does not meet the requirement, a shooting fill-in light lamp of the shooting equipment can carry out brightness adjustment, but frequent brightness adjustment can cause the shooting picture to fluctuate and flicker. On the basis, the scheme can detect whether the brightness of the camera shooting light supplement lamp is frequently adjusted, namely, whether the number of times of continuous adjustment of the brightness of the camera shooting light supplement lamp is very high is determined, the frequent adjustment of the brightness is recorded when the number of times of adjustment is very high, if the brightness of the camera shooting light supplement lamp is frequently adjusted, an adjusting mechanism of a camera shooting picture brightness tolerance interval is started, so that the default camera shooting picture brightness tolerance interval can be dynamically adjusted according to the current camera shooting picture brightness, the brightness of the camera shooting picture in at least partial time can be kept in the tolerance interval of the dynamic adjustment, and the brightness of the camera shooting light supplement lamp is not adjusted by starting the brightness adjusting mechanism. By utilizing the technical scheme, the camera shooting light supplement lamp of the camera cannot generate frequent brightness adjustment operation as far as possible, the number of times of picture flicker is reduced as far as possible in a camera shooting picture, and the camera shooting operation is ensured to be carried out under the condition that the camera shooting picture is stable.
On the basis of the above embodiment, optionally, before adjusting the default shooting picture brightness tolerance interval according to the current brightness of the shooting picture, the method further includes: whether the camera shooting light supplement lamp carries out the preset brightness continuous adjustment operation or not is detected, and when the preset brightness continuous adjustment operation is detected, the number of times of brightness continuous adjustment is obtained through statistics.
In this embodiment, when the number of times of continuous brightness adjustment of the camera shooting light supplement lamp is smaller than the preset number threshold, the camera shooting device may use the default camera shooting picture brightness tolerance interval to shoot a camera, and at this time, the camera shooting light supplement lamp may also supplement light according to the default camera shooting picture brightness tolerance interval during light supplement. After the camera shooting light supplement lamp is turned on, if the brightness of the camera shooting picture is not in a default camera shooting picture brightness tolerance interval, the camera shooting light supplement lamp can be triggered to conduct brightness adjustment operation all the time. The influence of the brightness adjustment operation within a small number of times or a short time on the shooting picture is not very serious, but the picture flicker phenomenon obviously appears on the shooting picture due to the adjustment for many times or a long time. Therefore, whether the shooting fill-in light performs the preset brightness continuous adjustment operation needs to be detected in real time, so as to trigger and adjust the default shooting picture brightness tolerance interval according to the adjustment times.
In the present embodiment, the preset continuous brightness adjustment operation includes continuously increasing the brightness, continuously decreasing the brightness, and continuously performing a cyclic adjustment operation of increasing the brightness and decreasing the brightness. Here, since the continuous brightness increase and the continuous brightness decrease cause the continuous brightness decrease, and the adjustment direction of the brightness is along one direction, the continuous brightness increase and the continuous brightness decrease have a smaller effect on the flicker of the captured image, which is not specifically described herein. However, the continuous adjustment operation of increasing the brightness and decreasing the brightness may cause the adjustment in the brightness increasing direction and the adjustment in the brightness decreasing direction, and the repeated adjustment may cause the phenomenon of flickering of the brightness, i.e. the problem of flickering of the image, which is the most serious problem in the third continuous adjustment of the brightness. Therefore, the following description will be given taking as an example a preset continuous luminance adjustment operation as a cyclic adjustment operation of continuously performing the high luminance adjustment and the low luminance adjustment.
In an optional example, whether the current brightness adjustment direction of the camera shooting light supplement lamp is the same as the previous brightness adjustment direction is detected, and whether the time difference between the ending time of the previous brightness adjustment and the starting time of the current brightness adjustment is within a preset time threshold value is detected. If the adjustment directions of the camera light supplement lamp and the camera light supplement lamp are different and the time difference is within the preset threshold value, the fact that the camera light supplement lamp is in continuous adjustment operation of preset brightness is indicated. At this time, the brightness adjustment operations in the current brightness adjustment direction are accumulated, and then the number of times of continuous brightness adjustment of the camera shooting light supplement lamp during the preset brightness continuous adjustment operation can be counted. If the adjustment directions of the light supplement lamp and the camera light supplement lamp are the same or the time difference is not within the preset threshold value, the fact that the camera light supplement lamp is detected and the preset brightness continuous adjustment operation is not carried out indicates that the accumulated result is directly cleared.
In this embodiment, fig. 3 is a schematic diagram illustrating counting the number of times of continuous brightness adjustment when the light supplement lamp performs brightness adjustment according to an embodiment of the present invention. Referring to fig. 3, the brightness adjustments corresponding to the counted brightness continuous adjustment times are continuous, and if there is a discontinuous brightness adjustment in the brightness adjustment process, the previously accumulated and counted brightness continuous adjustment times need to be cleared, and accumulation is performed again when waiting for the next brightness adjustment operation to meet the conditions. Alternatively, the number of times of continuous adjustment of the brightness may be counted by a counter at the setting counter. Therefore, the continuous adjustment times of the brightness of the camera shooting light supplement lamp can be obtained according to the process.
It should be noted that the number of continuous brightness adjustments requires setting an upper threshold for brightness adjustments, so as to avoid endless brightness adjustments. It should be noted that the upper limit threshold of the number of continuous brightness adjustments may be determined according to the tolerable time length for the flicker phenomenon, and the value is preferably small or not large.
Fig. 4 is a flowchart of another image capturing method provided in an embodiment of the present invention, which is further optimized based on the above-described embodiment, and the embodiment of the present invention may be combined with various alternatives in one or more of the above-described embodiments. As shown in fig. 4, the image capturing method provided in the embodiment of the present invention specifically includes the following steps:
s410, in the shooting process, if the number of times of continuous brightness adjustment of the shooting fill-in light is detected to be larger than or equal to a preset number threshold, determining the interval average brightness of a default shooting picture brightness tolerance interval; the interval average brightness is obtained according to an interval upper limit value and an interval lower limit value corresponding to a default shooting picture brightness tolerance interval.
In this embodiment, when it is detected that the number of times of continuous adjustment of the brightness of the camera supplementary lighting is greater than or equal to the preset number threshold, the upper limit of the interval corresponding to the shooting picture brightness tolerance interval may be added to the lower limit of the interval, and half of the addition result is used as the average brightness of the interval.
And S420, increasing the range of the default shooting picture brightness tolerance interval according to the brightness and the interval average brightness of the current shooting picture of the shooting equipment to obtain a new shooting picture brightness tolerance interval, wherein the brightness of the current shooting picture belongs to the new shooting picture brightness tolerance interval.
In this embodiment, in the foregoing process, when the number of times of continuously adjusting the brightness of the camera supplementary lighting lamp is greater than or equal to the preset number threshold, the brightness of the current camera image may be within the default camera image brightness tolerance interval or may not be within the default camera image brightness tolerance interval. At this time, it is necessary to calculate an absolute value of a luminance difference between the luminance of the current imaging screen and the section average luminance as a luminance change tolerance value. And the sum of the interval average brightness and the brightness change tolerance value and the difference between the interval average brightness and the brightness change tolerance value form a new shooting picture brightness tolerance interval. At this time, the luminance of the current imaging screen is necessarily included in the new imaging screen luminance tolerance section.
In this embodiment, fig. 5 is a schematic diagram of adjusting a luminance tolerance interval of an image capturing screen according to an embodiment of the present invention. Referring to fig. 5, the brightness of the current camera may be just the upper limit value of the new camera brightness tolerance interval, although the brightness of the current camera is already in accordance with the requirement after the new camera brightness tolerance interval is used, the camera fill-in light is not adjusted any more. However, the brightness of the shooting picture slightly fluctuates, so that once the brightness of the shooting picture slightly fluctuates, the brightness of the shooting picture inevitably exceeds a new shooting picture brightness tolerance interval, and the brightness adjustment of the shooting fill-in light is triggered again.
In this embodiment, in order to extend the time of using the new shooting picture brightness tolerance interval, an interval adjustment parameter may be preset, and the new shooting picture brightness tolerance interval is formed by adding the interval average brightness, the brightness change tolerance value, and the interval adjustment parameter, and the difference between the interval average brightness, the brightness change tolerance value, and the interval adjustment parameter. The value of the interval adjustment parameter is preferably small, but not large, and only needs to be a positive value. Therefore, even if the brightness of the shooting picture fluctuates slightly, the brightness value of the shooting picture is still in the new shooting picture brightness tolerance interval, and the new shooting picture brightness tolerance interval is not broken through frequently. However, if the value of the interval adjustment parameter is too large, the range of the new shooting screen brightness tolerance interval may be too large, and the screen exposure adjustment may be too slow.
And S430, controlling the shooting fill-in light according to the new shooting picture brightness tolerance interval, and continuing to carry out shooting operation.
In an optional manner of this embodiment, the method for controlling the shooting fill-in light according to the new shooting picture brightness tolerance interval and continuing the shooting operation specifically includes the following steps a1 to A3:
step A1, when a new shooting picture brightness tolerance interval is used, determining the brightness of the next shooting picture of the shooting equipment according to a preset time interval; the next image pickup screen is temporally located after the current image pickup screen.
In the present embodiment, when a new imaging screen luminance tolerance section is obtained, the imaging apparatus can use the new imaging screen luminance tolerance section for imaging. At this time, the next imaging screen refers to a screen of the surrounding environment captured by the imaging apparatus through the imaging lens during the use of the new imaging screen luminance tolerance section. As can be seen, the next camera shot is temporally located after the current camera shot.
It should be noted that the "current image capture screen" and the "next image capture screen" are merely used to distinguish image capture screens, so as to avoid confusion between different image capture screens. The next image pickup picture temporally located after the current image pickup picture refers to temporal distinction within the same loop operation.
And step A2, if the brightness of the next shooting picture is detected to belong to a new shooting picture brightness tolerance interval, the shooting fill-in light is not triggered to adjust the brightness, the brightness of the shooting picture of the shooting equipment is stabilized, and the shooting operation is continued.
In this embodiment, after the new shooting picture brightness tolerance interval is used, when the brightness of the next shooting picture belongs to the new shooting picture brightness tolerance interval, because the brightness of the shooting picture meets the requirement, the shooting fill-in light is not triggered to adjust the brightness, so that the brightness of the shooting fill-in light is kept unchanged, and the brightness of the shooting picture of the shooting equipment can be stabilized.
Step A3, if the brightness of the next shooting picture is detected not to belong to the new shooting picture brightness tolerance interval, detecting whether the shooting light supplement lamp is in an on state; and when the camera shooting light supplement lamp is detected to be turned on, triggering the brightness adjustment of the camera shooting light supplement lamp again, and continuing the camera shooting operation.
In this embodiment, if it is detected that the luminance of the next shooting picture does not belong to the new shooting picture luminance tolerance interval, it is determined preferentially whether the shooting fill-in light is in the off state. And if the camera shooting light supplement lamp is in the on state, triggering the camera shooting light supplement lamp again to adjust the brightness. Meanwhile, the new shooting picture brightness tolerance interval needs to be restored to the default shooting picture brightness tolerance interval, and then the next round of shooting picture brightness tolerance interval is adjusted on the basis of the default shooting picture brightness tolerance interval. In other words, in the next operation, the default shooting picture brightness tolerance interval is adjusted, and not the new shooting picture brightness tolerance interval obtained last.
In the embodiment, because the brightness of the camera shooting fill-in light is not adjusted any more, under normal conditions, the brightness of the next camera shooting picture generally belongs to a new camera shooting picture brightness tolerance interval, unless the illumination in the surrounding environment changes suddenly, for example, the ambient illumination is sufficient (because the brightness of the camera shooting fill-in light does not change any more, it is visible that the illumination caused by the camera shooting fill-in light is not sufficient here), and the new camera shooting picture brightness tolerance interval does not meet the requirement obviously at this time. In this case, the image capturing apparatus usually returns to the default image capturing picture brightness tolerance interval, and triggers the brightness adjustment operation of the image capturing fill-in light according to the default image capturing picture brightness tolerance interval, so that the default image capturing picture brightness tolerance interval needs to be continuously adjusted.
The embodiment of the invention provides a shooting scheme, and by utilizing the technical scheme, the default shooting picture brightness tolerance interval can be subjected to adaptive dynamic adjustment according to the brightness of the current shooting picture of the shooting equipment, the phenomenon that the brightness quality of the shooting picture is influenced by overlarge adjustment of the default shooting picture brightness tolerance interval is avoided, meanwhile, the shooting light supplement lamp can supplement light according to the new shooting picture brightness tolerance interval, the shooting light supplement lamp of a camera can be prevented from frequent brightness adjustment operation as far as possible, the shooting picture is ensured to reduce the picture flickering frequency as far as possible, and the shooting operation is ensured to be carried out under the condition that the shooting picture is stable.
Fig. 6 is a flowchart of another image capturing method provided in an embodiment of the present invention, which is further optimized based on the above embodiment, and the embodiment of the present invention may be combined with various alternatives in one or more of the above embodiments. As shown in fig. 6, the image capturing method provided in the embodiment of the present invention specifically includes the following steps:
s610, in the shooting process, if the continuous adjustment times of the brightness of the shooting supplementary lighting lamp is detected to be larger than or equal to the preset times threshold value, the default shooting picture brightness tolerance interval is adjusted to be the preset shooting picture brightness tolerance interval, so that the interval ranges of the new shooting picture brightness tolerance interval and the default shooting picture brightness tolerance interval are both contained in the interval range of the preset shooting picture brightness tolerance interval, and the preset adjustment time is continued.
In this embodiment, it has been described above that, when the number of times of continuously adjusting the brightness of the camera shooting light supplement lamp is greater than or equal to the preset number threshold, the brightness of the current camera shooting picture may not be within the default camera shooting picture brightness tolerance interval, and at this time, the camera shooting light supplement lamp still performs light supplement according to the default camera shooting picture brightness tolerance interval, so as to continue to trigger the brightness adjustment of the camera shooting light supplement lamp. Therefore, the image pickup picture is unstable, that is, the exposure is continuously and violently adjusted during the flashing period, the exposure parameters are unstable, and the accurate image pickup picture brightness cannot be obtained, so that the obtained image pickup picture brightness has a large error. Therefore, the default shooting picture brightness tolerance interval is temporarily adjusted to be the preset shooting picture brightness tolerance interval, and the shooting picture is guaranteed to be stabilized firstly to the maximum extent and does not flicker.
In this embodiment, the interval range of the preset image capturing frame brightness tolerance interval far includes the interval range of the default image capturing frame brightness tolerance interval, and if the preset image capturing frame brightness tolerance interval is used all the time, the image exposure adjustment will be too slow. For example, the upper limit value of the preset shooting picture brightness tolerance interval is a preset multiple of the upper limit value of the default shooting picture brightness tolerance interval, and the preset multiple is a very large value; meanwhile, the lower limit value of the preset shooting picture brightness tolerance interval is also a preset multiple of the lower limit value of the default shooting picture brightness tolerance interval. The preset multiple may be 10 times, 100 times or even more. Therefore, only the preset shooting picture brightness tolerance interval needs to be used temporarily, and the preset adjustment time is continued. And when the time for using the preset shooting picture brightness tolerance interval exceeds the preset adjusting time, automatically abandoning the preset shooting picture brightness tolerance interval. Optionally, when the preset shooting picture brightness tolerance interval is abandoned, if a new shooting picture brightness tolerance interval is obtained, the new shooting picture brightness tolerance interval is directly used; otherwise, the default shooting picture brightness tolerance interval can be continuously used to wait for obtaining a new shooting picture brightness tolerance interval.
S620, determining and recording the brightness of at least two shooting pictures within preset adjusting time; the brightness of the shooting picture in the preset adjusting time belongs to a preset shooting picture brightness tolerance interval, and the shooting picture in the preset adjusting time is located before the current shooting picture in terms of time.
And S630, adjusting the default shooting picture brightness tolerance interval according to the brightness of the current shooting picture to obtain a new shooting picture brightness tolerance interval.
In this embodiment, a specific implementation scheme for adjusting the default shooting picture brightness tolerance interval is to determine the interval average brightness of the default shooting picture brightness tolerance interval; determining interval adjusting parameters of a shooting picture brightness tolerance interval; the interval adjusting parameter is obtained according to the brightness fluctuation condition of the shooting picture within the preset adjusting time, and the value of the interval adjusting parameter is a positive value; and increasing the interval range of the default shooting picture brightness tolerance interval according to the brightness of the current shooting picture of the shooting equipment, the interval average brightness and the interval adjusting parameter.
The determination method of the interval adjustment parameter in this embodiment is different from the preset interval adjustment parameter in the foregoing embodiment, the interval adjustment parameter in the foregoing embodiment is preset, and the interval adjustment parameter in this embodiment is set in real time according to the fluctuation condition of the brightness of the multiple images acquired within the preset adjustment time, and meets the environmental condition of the image pickup apparatus, so that the interval range of the subsequently determined new image-pickup-image-brightness tolerance interval is not too large, and is not too small, which may cause frequent breakthrough of the new image-pickup-image-brightness tolerance interval during fine environmental adjustment, and prolong the service time of the new image-pickup-image-brightness tolerance interval.
And S640, controlling the shooting light supplement lamp according to the new shooting picture brightness tolerance interval, and continuing to carry out shooting operation.
The embodiment of the invention provides a shooting scheme, and by utilizing the technical scheme, a shooting picture is stabilized firstly, the accuracy of the brightness of the determined shooting picture is ensured, and then the default shooting picture brightness tolerance interval is subjected to adaptive dynamic adjustment according to the brightness of the current shooting picture of the shooting equipment, so that the influence on the brightness quality of the shooting picture caused by overlarge adjustment of the default shooting picture brightness tolerance interval is avoided, meanwhile, a shooting light supplement lamp can supplement light according to the new shooting picture brightness tolerance interval, a shooting light supplement lamp of a camera can be prevented from frequent brightness adjustment operation as far as possible, the number of times of picture flicker of the shooting picture is reduced as far as possible, and the shooting operation is ensured under the condition of stable shooting picture.
