The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

The flow charts shown in the drawings are just illustrations, and do not necessarily include all contents and operations/steps, nor must they be performed in the order described. For example, some operations/steps can be decomposed, combined or partly combined, so the actual order of execution may be changed according to the actual situation.

Camera devices generally have a time-lapse photography function. When the camera device works in the time-lapse photography mode, it continuously shoots images of many frames at intervals within a period of time, and then synthesizes the captured images into a video. The shooting interval is usually set by the user or automatically. However, after the above-mentioned shooting interval is set, it will not automatically and flexibly change according to the actual shooting situation, and the video effect synthesized after shooting cannot truly reflect the actual shooting situation, which affects the user experience.

The embodiment of the present application provides a shooting method for time-lapse photography, a camera control device, a camera device, and a storage medium. During each cycle shooting process of time-lapse photography, the wake-up camera device is controlled to enter the Dormant state, wake up the camera device in the dormant state to take a second image when the wake-up time is reached, wherein the wake-up time is set according to the motion state of the camera device used to take the first image after waking up; The image generates the corresponding video. Since the wake-up time for shooting the second image is set according to the motion state of the imaging device used to capture the first image after waking up, the second image is the next frame image of the first image, that is, when the imaging device captures the first image The wake-up time of the second image of the next frame is also determined according to its own motion state. In this way, the shooting interval is not fixed, but automatically and flexibly changes according to the motion state when the image is captured by the camera device. The video effect can truly reflect the actual shooting situation and improve the user experience.

Some implementations of the present application will be described in detail below in conjunction with the accompanying drawings. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.

Referring to FIG. 1 , FIG. 1 is a schematic flowchart of an embodiment of a shooting method for time-lapse photography in the present application, and the method includes: step S101 and step S102 .

Step S101: During each cycle of time-lapse photography, control the awakened imaging device to enter a dormant state after capturing the first image, and wake up the dormant imaging device when the wake-up time is reached to capture a second image, wherein The wake-up time is set according to the motion state of the camera device used to capture the first image after wake-up.

Step S102: Generate a corresponding video according to the captured image.

Time-lapse photography, also known as time-lapse photography and time-lapse video, is a shooting technique that compresses time. It usually takes a group of photos, and later combines the photos into a video to compress the process of minutes, hours or even days into a short period of time and play it as a video. Simply put, it is a photographic technique that captures images at a lower frame rate and then plays them back at a normal or faster rate.

In this embodiment, the first image is an image captured before the second image, and the second image is an image captured behind the first image. The cycle shooting process of time-lapse photography can refer to that after the camera device captures a frame of image (i.e. the first image), the camera device enters a sleep state, sleeps for a period of time, and when the shooting time of the next frame is reached, it is the wake-up time, and then Wake up the camera device in the dormant state, and after the awakened camera device captures a frame of image (ie, the second image), the camera device enters the dormant state, and so on, until the end of the cycle. In this way, the dormancy function of the camera device is added to the cycle shooting process of time-lapse photography, and the special shooting process of waking up can extend the battery life of the camera device when shooting time-lapse photography, without changing the battery or external power supply in the middle , It can last for a long time, such as more than 8 hours, which is very convenient for users to take long time-lapse photography.

During each cycle shooting process of the time-lapse photography, the wake-up time is set according to the motion state of the camera device used to shoot the first image after wake-up. The state of motion can refer to the state of an object relative to a reference frame when it is performing mechanical motion. The motion state includes static, uniform motion, accelerated motion, decelerated motion, variable speed motion, and also has various states such as linear motion and curved motion.

There are many ways to determine the motion state of the camera device. For example, a sensor capable of detecting the motion state of the camera device is configured on the camera device, such sensors include but are not limited to: accelerometers, rotation sensors, vibration sensors, inertial measurement units, and so on. Another example: the motion state of the camera device can also be determined through the images captured by the camera device.

According to the motion state of the camera device, an appropriate shooting interval is determined, and a wake-up time for the camera device to capture a next frame of image can be determined according to the shooting interval time. Usually, if there is intense movement, the interval between shots will be short, and if it is still, the interval between shots will be long. For example: running or turning, the shooting interval can be 1s; walking, the shooting interval can be 2s; still, the shooting interval can be 8s, and so on. In this way, during each cycle of time-lapse photography, the shooting interval between two shots can be dynamically modified in this way; the wake-up time is related to the shooting interval, and the next shot can be determined by determining the shooting interval between two shots. The wake-up time for the frame image.

It should be noted that one of the more common application scenarios of the method in the embodiment of the present application is a scene where the camera is in motion to shoot, for example: the camera is set on a handheld device (such as a hand-held pan/tilt, a smart phone, etc. ), the camera moves with the handheld device and shoots; the camera is set on a mobile platform (for example: UAV, unmanned vehicle, etc.), the camera moves with the mobile platform, and shoots; the camera is set On a wearable device (such as a smart watch, a smart bracelet, etc.), the camera device follows the movement of the wearable device and takes pictures; or the camera device is worn on a person's body or head; and so on. In these application scenarios, the movement of the camera device is usually passive. Sometimes it moves, sometimes it is still, sometimes it moves violently, sometimes it moves slowly, sometimes it moves fast, and sometimes it slows down. The wake-up time cannot be changed once it is set, and the video synthesized by shooting in this way obviously cannot reflect the real shooting situation; while using the method of the embodiment of this application to set the wake-up time according to the motion state of the camera device, the video is synthesized by shooting The video can reflect the real shooting situation, which can improve the user experience.

In one embodiment, when the camera is in a dormant state, the internal memory of the camera can be controlled to be in a self-refresh (SR, Self Refresh) state, and the external circuit of the image processing chip of the camera can be controlled to be in a power-off state to control the camera. In the image processing chip of the device, other devices except timing-related devices are turned off. Since the time that the camera is in the sleep state is limited, when the image processing chip is used to time the sleep time, in order to reduce power consumption, during the camera is in the sleep state, in addition to the devices related to the timing function, the image processing chip , other devices are turned off in a non-working state.

In an embodiment, when the camera device is in a dormant state, the battery of the camera device is in a low discharge voltage state and/or a low current state. After one frame of image is taken, before the next frame of image is taken, the discharge voltage and/or current of the battery can be reduced to reduce the power consumption of the battery, thereby prolonging the working time of the battery and the working time of the camera state.

In the embodiment of the present application, during each cycle of time-lapse photography, the awakened imaging device is controlled to enter the dormant state after capturing the first image, and the dormant imaging device is awakened to capture the second image when the wake-up time is reached. Wherein the wake-up time is set according to the motion state of the camera device used to capture the first image after wake-up; and a corresponding video is generated according to the captured image. Since the wake-up time for shooting the second image is set according to the motion state of the imaging device used to capture the first image after waking up, the second image is the next frame image of the first image, that is, when the imaging device captures the first image The wake-up time of the second image of the next frame is also determined according to its own motion state. In this way, the shooting interval is not fixed, but automatically and flexibly changes according to the motion state when the image is captured by the camera device. The video effect can truly reflect the actual shooting situation and improve the user experience.

Details related to the wake-up time will be described in detail below.

Referring to Fig. 2, in an embodiment, the method may further include: step S103 and step S104.

Step S103: After waking up the camera device for capturing the first image, determine the motion state of the camera device.

Step S104: Set a wake-up time for capturing the second image according to the motion state of the camera device.

In this embodiment, in order to reduce power consumption as much as possible, after waking up the camera device for shooting the first image, determine the motion state of the camera device, and set the wake-up time for shooting the second image accordingly. Wherein, step S103 and step S104 may be completed during a time period after the camera device for shooting the first image wakes up and before the camera device for shooting the first image goes to sleep. For example, step S103 and step S104 may be performed immediately after the camera device used to capture the first image wakes up, and then subsequent steps related to capturing the first image may be performed.

In an embodiment, the motion state of the camera device is determined according to the motion data of the camera device. That is, step S103, after waking up the camera device for taking the first image, determining the motion state of the camera device may include: sub-step S103A1 and sub-step S103A2, as shown in FIG. 3 .

Sub-step S103A1: After waking up the camera device for capturing the first image, acquire motion data of the camera device.

Sub-step S103A2: Determine the motion state of the camera according to the motion data of the camera.

The motion data of the camera device is usually detected by a sensor that detects the motion state of the camera device. According to the motion data of the camera device, the motion state of the camera device can be determined: whether it is still or in motion, and if it is in motion, how much is the motion, how long is the motion, and so on.

In an embodiment, the sub-step S103A1, after waking up the camera device for taking the first image, acquiring motion data of the camera device may also include: waking up the camera device for taking the first image After the device is installed, motion data of the camera device from a dormant state before waking up to when waking up is acquired.

The time period of motion data obtained by monitoring the motion state of the imaging device in this embodiment is from the dormant state before waking up to the time period when waking up, that is, this embodiment continuously detects the motion state of the imaging device, even if the imaging device is in a dormant state, In this way, relatively accurate and comprehensive information on the motion state of the camera device can be obtained, which provides support for setting the wake-up time reasonably and accurately. In this embodiment, the sensor for detecting the motion state of the camera device is still working when the camera device is in the dormant state, and the acquisition module for collecting sensor data is also working.

In an embodiment, the camera 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 comprehensively detect the motion state of the camera state.

In an embodiment, the motion state of the camera device is determined according to the captured images. That is, step S103, after waking up the camera device for capturing the first image, determining the motion state of the camera device may further include: sub-step S103B1 and sub-step S103B2, as shown in FIG. 4 .

Sub-step S103B1: After waking up the camera device for capturing the first image, control the camera device to perform pre-shooting.

Sub-step S103B2: Determine the motion state of the camera according to the pre-captured image.

For example: multiple targets can be detected in the pre-shot image, judge whether the multiple targets appear or not appear in multiple consecutive images, analyze whether the targets appearing continuously in multiple images are moving targets, and then combine Other targets are judged together to determine whether the target is moving because the target itself is moving, or because the camera is moving, or because the camera is also moving while the target is moving, and the motion state of the camera is determined according to the judgment result.

The details of determining the shooting parameters before shooting an image will be described in detail below.

If the camera device is awakened from a dormant state and directly captures images without adjusting the shooting parameters, usually the randomly obtained shooting parameters are not suitable, which will affect the quality of the image and the quality of the subsequent synthesized video. Therefore, after waking up the camera device, appropriate shooting parameters can be determined first, and then the shooting can be performed, so that image quality and synthesized video quality can be guaranteed. That is, in step S101, waking up the dormant imaging device to take a second image when the wake-up time is reached may include: sub-step S101A1, sub-step S101A2, and sub-step S101A3, as shown in FIG. 5 .

Sub-step S101A1: wake up the imaging device in the dormant state when the wake-up time is reached.

Sub-step S101A2: Determine shooting parameters of the camera device used to shoot the second image.

Sub-step S101A3: controlling the camera device to shoot the second image with the shooting parameters.

Shooting parameters may refer to parameters used when shooting images, such as shutter speed, aperture, focal length, sensitivity ISO value, auto-focus parameters, auto-exposure parameters, auto-white balance parameters, whether to turn on the flash, etc. In an embodiment, the shooting parameters may include one or more of automatic exposure parameters, automatic white balance parameters, and automatic focus parameters. One or more of the automatic exposure parameters, automatic white balance parameters and automatic focus parameters are the key shooting parameters that affect the image quality, and one or more of the automatic exposure parameters, automatic white balance parameters and automatic focus parameters are mainly determined. The time for determining shooting parameters can be shortened, thereby reducing power consumption.

Determining the shooting parameters of the camera device takes time and consumes power consumption. In order to reduce the time spent and power consumption as much as possible, the shooting parameters of the camera device can be determined in a high frame rate mode. That is, in an embodiment, the sub-step S101A2, the determining the shooting parameters of the camera device used to capture the second image may include: controlling the camera device to operate at a high frame rate with a frame refresh rate higher than a preset frame rate The shooting parameters of the camera device are determined in the rate mode.

The high frame rate mode may refer to a mode in which the frame refresh rate is higher than a preset frame rate. For example, the preset frame rate defaults to a maximum of 30 frames per second, then a frame refresh rate mode greater than 30 frames per second can be considered a high frame rate mode, such as a maximum of 60 frames per second, a maximum of 120 frames per second, and so on. The more the number of frames, the more images are refreshed in the same second, so that the shooting parameters corresponding to the images with good quality can be quickly determined.

In order to further reduce power consumption, in an embodiment, substep S101A2 may also include:

A. Control the camera device to enter the high frame rate mode.

B. In the high frame rate mode, continuously set multiple sets of setting parameters with preset intervals.

C. Acquiring the statistical values of multiple consecutive groups corresponding to the set parameters.

D. Determine a shooting parameter used by the camera device to shoot the second image according to the statistical values of the multiple consecutive groups.

In related technologies, the common continuous closed-loop convergence process is: setting parameters -> obtaining statistical values -> adjusting parameters -> setting parameters; the convergence process adopted in the embodiment of the present application is: continuously setting n groups of settings with preset intervals Parameters, acquiring n consecutive groups of statistical values corresponding to the set parameters, and selecting the most suitable or closest shooting parameters for shooting the second image by the camera device according to the n groups of statistical values. Compared with the continuous closed-loop convergence process adopted in the related art, the convergence process adopted in this embodiment takes a shorter time and is faster, so the power consumption can be further reduced.

In an embodiment, in order to prevent the brightness and color of the finally generated video from jumping, the shooting parameters of each shooting may be filtered, so that the changes of the shooting parameters are relatively smooth. That is, the above-mentioned D, said determining the shooting parameters used by the imaging device for shooting the second image according to the statistical values of the multiple consecutive groups may also include: determining the shooting parameters of the second image according to the statistical values of the multiple consecutive groups Statistical parameters of the imaging device; performing filtering processing on the statistical parameters to obtain shooting parameters used by the imaging device to capture the second image.

Similarly, in order that the brightness and color of the final generated video will not jump, the brightness of the image can also be smoothed when compositing the video. That is, step S102 , generating a corresponding video according to the captured image may include: sub-step S102A1 and sub-step S102A2 , as shown in FIG. 6 .

Sub-step S102A1: Perform brightness smoothing processing on the captured image.

Sub-step S102A2: Generate a corresponding video according to the smoothed image.

In an embodiment, in order to ensure the quality of the synthesized video, digital anti-shake processing is performed on the image when the video is synthesized. That is, step S102, the generating of the corresponding video according to the captured image may include: sub-step S102B1 and sub-step S102B2, as shown in FIG. 7 .

Sub-step S102B1: Perform digital anti-shake processing on the captured image.

Sub-step S102B2: Generate a corresponding video according to the digitally stabilized image.

Anti-shake can prevent the captured image from ghosting. Digital anti-shake is also called electronic anti-shake technology. This technology uses dynamic vectors in shake detection, and grasps the direction and amount of swing of the image according to the dynamic vector, and uses this as a reference to move the image position in parallel to generate a shake-free image. dynamic image.

Wherein, sub-step S102B1, performing digital anti-shake processing on the captured image may also include: performing digital anti-shake processing on the first image according to the motion state of the camera device that captured the first image; The motion state of the camera device of the second image, and perform digital anti-shake processing on the second image.

The image requiring digital anti-shake processing can make the digital anti-shake processing more accurate and ensure the quality of the image as much as possible by combining the motion state of the camera device that captures the image when the digital anti-shake processing is performed.
