Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a flowchart of an embodiment of a shooting method of time-lapse photography of the present application, where the method includes: step S101 and step S102.
Step S101: and in each cycle of the delayed photographing, controlling the awakened image pickup device to enter a dormant state after the first image is photographed, and awakening the image pickup device in the dormant state to photograph the second image when the awakening time is reached, wherein the awakening time is set according to the motion state of the image pickup device used for photographing the first image after the awakening.
Step S102: and generating a corresponding video according to the photographed image.
Time-lapse photography (Time-lapse photography), also called Time-lapse photography, time-lapse video recording, is a technique of Time-lapse compression. It takes a set of photos, and later compresses the process of minutes, hours and even days to play in video by concatenating the photos into a video in a short time. In short, it is a photographic technique that takes images at a lower frame rate and then plays the images at a normal or faster rate.
In this embodiment, the first image is an image taken before the second image, and the second image is an image taken after the first image. The cyclic shooting process of the delayed shooting may refer to that after the image capturing device captures an image of one frame (i.e., the first image), the image capturing device enters a sleep state, sleeps for a period of time, reaches a wake-up time when reaching a shooting time of a next frame, and wakes up the image capturing device in the sleep state, and after the waken-up image capturing device captures an image of one frame (i.e., the second image), the image capturing device enters the sleep state, so that the cycle is repeated until the cycle is ended. Through this kind of mode, add the function that camera device was dormant at the cyclic shooting process of delay shooting, the special shooting process of cooperation awakening can prolong camera device and shoot the duration of delay shooting time, can not change the battery in the middle, does not external power supply, can take a photograph for a long time of endurance, say more than 8 hours, very big convenience of customers shoots long-time delay shooting.
During each cycle of the time-lapse photographing, the wake-up time is set according to the motion state of the image pickup device for photographing the first image after the wake-up. The motion state may refer to a state of the object with respect to a certain reference frame when performing a mechanical motion. The motion state includes static, uniform motion, acceleration motion, deceleration motion, variable speed motion, linear motion, curve motion and other states.
There are many ways to determine the state of motion of the camera. For example, sensors are provided on the camera that can detect the motion state of the camera, such sensors including, but not limited to: accelerometers, rotation sensors, vibration sensors, inertial measurement units, and so forth. Another example is: the movement state of the image pickup device can also be determined by the image picked up by the image pickup device.
And determining proper shooting interval duration according to the motion state of the image pickup device, and determining the wake-up time of the image pickup device for shooting the next frame of image according to the shooting interval duration. In general, if the movement is intense, the shooting interval is long, and if the movement is still, the shooting interval is long. For example: running or turning, and shooting interval duration can be 1s; walking, and the shooting interval duration can be 2s; still, the shooting interval duration may be 8s, and so on. In this way, in each cycle shooting process of the time-lapse shooting, the shooting interval duration of the two shots can be dynamically modified in this way; the wake-up time is related to the shooting interval duration, and the wake-up time of the next frame of image can be determined by determining the shooting interval duration of two shots.
It should be noted that, one of application scenarios of the method in the embodiment of the present application is a scenario in which the image capturing device is in a motion state to capture images, for example: the camera device is arranged on the handheld equipment (such as a handheld cradle head, a smart phone and the like), moves along with the handheld equipment and shoots; the camera device is arranged on a mobile platform (such as an unmanned plane, an unmanned vehicle and the like), moves along with the mobile platform and shoots; the camera device is arranged on the wearable equipment (such as a smart watch, a smart bracelet and the like), moves along with the wearable equipment and shoots; or the camera device is worn on the body, the head and the like; etc. In these application scenes, the motion of the image capturing device is usually passive, and the motion is time-to-time motion, time-to-time stationary, time-to-time motion is intense, time-to-time motion is slow, time-to-time motion is fast, time-to-time motion is slow, and if the shooting interval duration or the wake-up time is set by a user or automatically, the shooting interval duration or wake-up time is set continuously, and the middle is unchanged, so that the synthesized video shot in this way obviously cannot reflect the real shooting condition; by adopting the method of the embodiment of the application, the wake-up time is set according to the motion state of the image pickup device, and the shot and synthesized video can reflect the real shooting condition, so that the user experience can be improved.
In an embodiment, when the image capturing apparatus is in the sleep state, the memory of the image capturing apparatus may be controlled to be in a Self Refresh (SR) state, the external circuit of the image processing chip of the image capturing apparatus may be controlled to be in a power-off state, and other devices in the image processing chip of the image capturing apparatus except for the timing related device may be controlled to be in a power-off state. Since the time in which the image pickup apparatus is in the sleep state is limited, in order to reduce power consumption when the timing of the sleep time is performed by the image processing chip, other devices within the image processing chip than the devices related to the timing function are turned off in the inactive state during the sleep state of the image pickup apparatus.
In an embodiment, when the image capturing apparatus is in the sleep state, the battery of the image capturing apparatus is in a low discharge voltage state and/or a low current state. After shooting one frame of image, before shooting the next frame of image, the discharging voltage and/or current of the battery are reduced, so that the power consumption of the battery is reduced, the working time of the battery is prolonged, and the working time of the shooting state is prolonged.
In the embodiment of the application, in each cycle shooting process of delayed shooting, the awakened image pickup device is controlled to enter a dormant state after a first image is shot, and the image pickup device in the dormant state is awakened to shoot a second image when the awakening time is reached, wherein the awakening time is set according to the motion state of the image pickup device used for shooting the first image after awakening; and generating a corresponding video according to the photographed image. The wake-up time for shooting the second image is set according to the motion state of the camera device for shooting the first image after wake-up, the second image is the next frame image of the first image, namely, the wake-up time of the second image of the next frame is determined according to the motion state of the camera device when shooting the first image, so that the shooting interval is not fixed, but automatically and flexibly changed according to the motion state of the camera device when shooting the image, the video effect synthesized after shooting can truly reflect the actual shooting condition, and the user experience can be improved.
Details regarding wake-up time are described in detail below.
Referring to fig. 2, in an embodiment, the method may further include: step S103 and step S104.
Step S103: and after waking up an image pickup device for picking up the first image, determining the motion state of the image pickup device.
Step S104: and setting the wake-up time for shooting the second image according to the motion state of the image shooting device.
In this embodiment, in order to reduce the power consumption as much as possible, after the image capturing device for capturing the first image is awakened, the motion state of the image capturing device is determined, and the awakening time for capturing the second image is set accordingly. Wherein, step S103 and step S104 may be completed in a period of time after the image capturing apparatus for capturing the first image wakes up until the image capturing apparatus for capturing the first image sleeps. For example, after the image capturing apparatus for capturing the first image wakes up, steps S103 and S104 may be performed immediately, and then the steps related to capturing the first image may be performed later.
In an embodiment, the movement state of the camera is determined from movement data of the camera. That is, step S103, after the waking up of the image capturing device for capturing the first image, determining the motion state of the image capturing device may include: substep S103A1 and substep S103A2, as shown in fig. 3.
Substep S103A1: and after waking up an image pickup device for picking up the first image, acquiring motion data of the image pickup device.
Substep S103A2: and determining the motion state of the image pickup device according to the motion data of the image pickup device.
The motion data of the image pickup device is generally detected by a sensor that detects the motion state of the image pickup device. The motion state of the image pickup device can be determined according to the motion data of the image pickup device: whether stationary or moving, if moving, how much, how long, etc.
In an embodiment, the step S103A1 of waking up the image capturing device for capturing the first image to obtain motion data of the image capturing device may further include: and after the image pickup device for shooting the first image is awakened, acquiring motion data of the image pickup device from a dormant state before awakening to awakening.
The time period of the motion data acquired by monitoring the motion state of the image pickup device is the time period from the sleep state before waking up to the wake-up time, namely the motion state of the image pickup device is continuously detected in the embodiment, even if the image pickup device is in the sleep state, the motion state of the image pickup device can be accurately and comprehensively informed, and support is provided for reasonably and accurately setting the wake-up time. In this embodiment, the sensor for detecting the motion state of the camera device still works when the camera device is in the sleep state, and the acquisition module for acquiring the sensor data also works.
In an embodiment, the image capturing device is provided with an inertial measurement unit, and the motion data is motion data measured by the inertial measurement unit. The inertial measurement unit (IMU, inertial Measurement Unit) can measure the three-axis attitude angle (or angular rate) and acceleration of the object, and can detect the motion state of the imaging state more comprehensively.
In one embodiment, the motion state of the imaging device is determined from the captured image. That is, step S103, after the waking up the image capturing device for capturing the first image, determining a motion state of the image capturing device may further include: substep S103B1 and substep S103B2, as shown in fig. 4.
Substep S103B1: and after waking up an image pickup device for picking up the first image, controlling the image pickup device to perform pre-shooting.
Substep S103B2: and determining the motion state of the image pickup device according to the pre-shot image.
For example: multiple targets can be detected in the pre-shot images, whether the multiple targets appear or do not appear in the multiple continuous images is judged, whether the targets appearing continuously in the multiple images are moving targets is analyzed, judgment is carried out by combining other targets, whether the targets move because the targets move or because the image pickup device moves or because the targets move at the same time, and the movement state of the image pickup device is determined according to the judgment result.
Details of determining the photographing parameters before photographing an image are described in detail below.
If the photographing parameters are not adjusted to directly photograph the image after the photographing device is awakened from the sleep state, the photographing parameters obtained randomly are generally unsuitable, so that the image quality and the video quality of subsequent synthesis can be affected. Therefore, after the camera device is awakened, proper shooting parameters can be determined first, and then shooting is carried out, so that the image quality and the synthesized video quality can be ensured. That is, in step S101, waking up the image capturing apparatus in the sleep state to capture the second image when the wake-up time is reached may include: sub-step S101A1, sub-step S101A2, and sub-step S101A3 are shown in fig. 5.
Substep S101A1: and waking up the image pickup apparatus in the sleep state when the wake-up time is reached.
Substep S101A2: imaging parameters of an imaging device for capturing the second image are determined.
Substep S101A3: and controlling the image pickup device to pick up the second image according to the shooting parameters.
The photographing parameters may refer to parameters used when photographing an image, such as a shutter speed, an aperture, a focal length, a sensitivity ISO value, an auto focus parameter, an auto exposure parameter, an auto white balance parameter, whether a flash is turned on, and the like. In an embodiment, the shooting parameters may include one or more of an auto-exposure parameter, an auto-white balance parameter, and an auto-focus parameter. One or more of the automatic exposure parameter, the automatic white balance parameter and the automatic focusing parameter are key shooting parameters influencing the image quality, and the one or more of the automatic exposure parameter, the automatic white balance parameter and the automatic focusing parameter are determined in a key mode, so that the time for determining the shooting parameters can be shortened, and the power consumption is reduced.
It takes time to determine the photographing parameters of the photographing apparatus, which can be determined in the high frame rate mode, consumes power, and reduces the power consumption in order to reduce the time spent as much as possible. That is, in an embodiment, the determining the photographing parameters of the photographing device for photographing the second image in the substep S101A2 may include: and controlling the image pickup device to determine shooting parameters of the image pickup device in a high frame rate mode that the image refresh rate is higher than a preset frame rate.
The high frame rate mode may refer to a mode in which the picture refresh rate is higher than a preset frame rate. For example, a preset frame rate of up to 30 frames per second by default, then a picture refresh rate mode greater than 30 frames per second may be considered a high frame rate mode, such as up to 60 frames per second, up to 120 frames per second, and so on. The more the number of frames is, the more the images are refreshed in the same second, so that the shooting parameters corresponding to the images with good quality can be rapidly determined.
To further reduce the power consumption, in an embodiment, the substep S101A2 may further include:
A. and controlling the image pickup device to enter the high frame rate mode.
B. In the high frame rate mode, a plurality of sets of setting parameters having preset intervals are continuously set.
C. And obtaining a plurality of continuous groups of statistical values corresponding to the setting parameters.
D. And determining shooting parameters of the shooting device for shooting the second image according to the continuous multiple groups of statistical values.
In the related art, a common continuous closed loop convergence process is adopted: setting parameters- > obtaining statistics- > adjusting parameters- > setting parameters; the convergence process adopted in the embodiment of the application is as follows: and continuously setting n groups of setting parameters with preset intervals, acquiring the statistics of the n groups of continuous setting parameters, and selecting the most suitable or closest imaging device for shooting the shooting parameters of the second image according to the n groups of statistics. Compared with the continuous closed loop convergence process adopted in the related art, the convergence process adopted in the embodiment takes shorter time and faster speed, so that the power consumption can be further reduced.
In an embodiment, in order that the finally generated video does not jump in brightness and color, the shooting parameters of each shooting may be filtered so that the changes of the shooting parameters are smoother. In other words, the determining, according to the statistics of the continuous multiple sets, a shooting parameter of the image capturing device for capturing the second image may further include: determining statistical parameters of the camera device according to the continuous multiple groups of statistical values; and filtering the statistical parameters to obtain shooting parameters of the image pickup device for shooting the second image.
Similarly, the brightness of the image may be smoothed when synthesizing the video so that the finally generated video does not jump in brightness or color. Namely, step S102, the generating a corresponding video according to the captured image may include: substep S102A1 and substep S102A2, as shown in fig. 6.
Substep S102A1: and carrying out brightness smoothing processing on the shot image.
Substep S102A2: and generating a corresponding video according to the image subjected to the brightness smoothing processing.
In one embodiment, to ensure the quality of the synthesized video, digital anti-shake processing is performed on the images while synthesizing the video. Namely, step S102, the generating a corresponding video according to the captured image may include: substep S102B1 and substep S102B2, as shown in fig. 7.
Substep S102B1: and carrying out digital anti-shake processing on the shot image.
Substep S102B2: and generating a corresponding video according to the image after the digital anti-shake processing.
The anti-shake can prevent the photographed image from having a ghost. The digital anti-shake technique is also called an electronic anti-shake technique, which uses a dynamic vector in the shake detection aspect to master the swing direction and the swing amount of an image according to the dynamic vector, and uses the dynamic vector as a reference to enable the image position to move in parallel, so that a dynamic image without shake is generated.
Wherein, the substep S102B1, performing digital anti-shake processing on the captured image, may further include: performing digital anti-shake processing on the first image according to the motion state of an imaging device for shooting the first image; and carrying out digital anti-shake processing on the second image according to the motion state of an image pickup device for picking up the second image.
The image to be subjected to the digital anti-shake processing is combined with the motion state of the image pickup device for picking up the image when the digital anti-shake processing is performed, so that the digital anti-shake processing is more accurate, and the quality of the image can be ensured as much as possible.
