in step 101, in the shooting process, a currently shot image is acquired as a first image every first preset time.
The image capturing device may be a mobile phone, a digital camera, a tablet computer, and the like, which is not limited in this embodiment.
In this embodiment, the image capturing apparatus may capture multiple frames of images, and in a low-speed shooting scene, the image capturing apparatus may determine a first preset time length in advance, and in the shooting process, the image capturing apparatus only acquires a currently captured image, but does not acquire all captured images, at every other first preset time length.

In step 102, the last frame image currently recorded is extracted as the second image.
In the shooting process, the image pickup apparatus may record an image, and each time the image pickup apparatus acquires a currently shot image, the last frame of image that has been currently recorded is extracted according to the recording time of each frame of recorded image.

The image pickup apparatus uses a currently acquired image as a first image, uses a currently recorded last frame image as a second image, and determines whether the first image is the same as the second image, and if it is determined that the first image is the same as the second image, it indicates that a difference between the first image and the second image is small, that is, a change of an object in the image is small, and at this time, if the first image is recorded, a waste of a storage space is caused. If it is determined that the first image is different from the second image, it indicates that the difference between the first image and the second image is large, that is, the change of the object in the image is large, and at this time, in order to record the change details of the object in detail, the image capturing apparatus records the first image.
According to the method provided by the embodiment, when the currently shot first image is different from the currently recorded last frame image, the first image is recorded, and when the currently shot first image is the same as the currently recorded last frame image, the recording of the first image is cancelled, so that the currently shot image can be recorded only when the difference between the images is large, so that the camera device can dynamically adjust the time interval between the recorded images according to the actual change condition of the object, namely when the object changes slowly, the time interval between the images is large, when the object changes quickly, the time interval between the images is small, and when the images are played subsequently, the change details of the object can be presented in detail without deleting the images with slow changes of the object, all the images are not required to be recorded, and the storage space of the images is saved.

and playing the images recorded in the shooting process according to a preset playing time interval, wherein the preset playing time interval is less than the first preset time length.
All the above-mentioned optional technical solutions can be combined arbitrarily to form the optional embodiments of the present invention, and are not described herein again.
Fig. 2 is a flowchart illustrating a method of recording an image, as shown in fig. 2, for use in an image capturing apparatus, according to an exemplary embodiment, including the steps of:
in step 201, in the process of capturing an image by an image capturing apparatus, when a first frame image is captured, the first frame image is recorded.
In daily life, the state of an object may change, such as a flower may open, a pointer may move, and the like. The image pickup apparatus can photograph an object, and the photographed image can reflect the state of the object. When the two taken images are different, it can be considered that the object is changed in the time interval in which the two taken images are taken, and when the two taken images are the same, it can be considered that the object is not changed in the time interval in which the two taken images are taken.
When the image pickup apparatus starts to take a first frame image, the first frame image is acquired and recorded. The first frame image is a first frame image recorded by the image pickup apparatus and is also a last frame image currently recorded. In the subsequent process, the image pickup apparatus may compare the last frame image currently recorded with the currently photographed image to determine a change condition of the object each time the currently photographed image is acquired.
In step 202, the image capturing apparatus acquires a currently captured image as a first image every first preset time period, and extracts a last frame image currently recorded as a second image.
In the shooting process, the shooting equipment acquires the currently shot image as a first image every the first preset time. The first preset time period is used to represent a minimum value of a time interval between images, and may be determined in advance by the image capturing apparatus according to a delay time interval of a general image capturing apparatus when performing low-speed shooting and a change frequency of a captured object, which is not limited in this embodiment.
In order to know the change of the object, when the image capturing apparatus acquires the currently captured image, the last frame image currently recorded may be extracted from all the images recorded as the second image. The time interval between the second image and the first image is the smallest in all the recorded images, and the change condition of the object can be judged by comparing the first image and the second image.
In the practical application process, the camera equipment comprises a camera, a processor, a timer and a memory, wherein the camera is used for shooting images, the processor is used for acquiring the images shot by the camera, the timer is used for counting the time length, and the memory is used for recording the images. When the camera equipment starts to shoot a first frame of image, the first frame of image is recorded through the memory, the processor is used for setting the maximum duration of the timer to be the first preset duration, the timer is started to start timing, when the duration counted by the timer reaches the first preset duration, timing is stopped, the processor is triggered, the processor acquires the current image shot by the camera, and the first frame of image recorded currently is acquired from the memory. Then, the camera device resets the timer through the processor, so that the timer restarts to count time, so as to continue to acquire the image currently shot by the camera after the first preset time length elapses.
In step 203, the image capturing apparatus segments the first image using an image segmentation algorithm to obtain a segment line of the first image, and segments the second image using the image segmentation algorithm to obtain a segment line of the second image.
In order to determine whether the content of the image changes, the image capturing apparatus may use the same image segmentation algorithm to segment the first image and the second image respectively to obtain a segmentation line of the first image and a segmentation line of the second image, and determine whether the content of the image changes according to the segmentation lines of the first image and the second image.
The image segmentation algorithm may be a region growing segmentation algorithm based on uniform scattering, and the number of scattering points determined during image segmentation may be determined according to the size of an image picture captured by the image capturing apparatus and the distance between the object and the image capturing apparatus.
In step 204, the image pickup apparatus determines whether or not the dividing line of the first image matches the dividing line of the second image, and if so, executes step 205, and if not, executes step 210.
The image capturing apparatus obtains a position of each segment line of the first image, obtains a position of each segment line of the second image, determines whether the positions of the segment lines of the first image and the corresponding segment lines of the second image match, and determines that the segment lines of the first image match the segment lines of the second image and the content of the first image is unchanged, that is, the shape of the object is unchanged, when the image capturing apparatus determines that the positions of each segment line of the first image and the corresponding segment line of the second image both match, the following step 205 may be continuously performed to determine whether the object is changed. When the image pickup apparatus determines that the position of any one of the dividing lines in the first image does not match the position of the corresponding dividing line in the second image, and determines that the first image is different from the second image and the shape of the object is changed, the image pickup apparatus may record the first image in order to record the change details of the object in detail.
In step 205, the image capturing apparatus calculates a pixel value change rate between each pixel point in the first image and a corresponding pixel point in the second image.
Even if the form of the object is not changed, the color, brightness, and the like of the object may be changed, and in order to determine whether the color or brightness of the object is changed, the image capturing apparatus may calculate a pixel value change rate between each pixel point in the first image and a corresponding pixel point in the second image. For each pixel point of the first image, the camera device can acquire the pixel value of the pixel point, acquire the pixel value of the pixel point which is positioned at the same position as the pixel point in the second image, and calculate the change rate between the two pixel values.
Taking an image in a YUV format as an example, assuming that the pixel value of the pixel point (x, Y) in the first image is (Y1, U1, V1), and the pixel value of the pixel point (x, Y) in the second image is (Y2, U2, V2), the pixel value change rates of the YUV three dimensions are: the pixel value change rate of the pixel point may be max (Ry, Ru, Rv).
It should be noted that, in this embodiment, the image capturing apparatus first executes steps 203 and 204, and executes step 205 again when determining that the dividing line of the first image does not match the dividing line of the second image, and in practical application, the image capturing apparatus may also execute steps 203 and 205 simultaneously, or execute step 205 first and execute step 203 again, which is not limited in this embodiment.
In step 206, the image pickup apparatus determines whether the pixel value change rate of each pixel point is smaller than a first preset threshold, if so, step 211 is executed, and if not, step 207 is executed.
In this embodiment, when the pixel value change rate of the pixel point is smaller than the first preset threshold, it may be considered that the pixel value of the pixel point is not changed, and when the pixel value change rate of the pixel point is not smaller than the first preset threshold, it may be considered that the pixel value of the pixel point is changed.
Correspondingly, the camera equipment judges whether the pixel value change rate of each pixel point is smaller than a first preset threshold value. And if the pixel value change rate of each pixel point is smaller than a first preset threshold value, determining that the pixel values of the pixel points of the first image and the second image are the same, namely the color and the brightness of the object are not changed. Since the image capturing apparatus determines in step 204 that the dividing line of the first image matches the dividing line of the second image, if it is also determined that the pixel value change rate of each pixel point is smaller than the first preset threshold, it may be determined that the first image is the same as the second image and the object is not changed, and the image capturing apparatus may cancel recording the first image and continue to execute step 202 to obtain the next frame image. By canceling the recording of the first image when the first image is the same as the second image, it is possible to save memory space, ignore images when the object is not changed, and relatively record changed images with emphasis, thereby highlighting details of the change of the object.
If the pixel value change rate of any pixel point is not less than the first preset threshold, it indicates that the pixel points include pixel points whose pixel value change rate is not less than the first preset threshold, that is, the pixel points include changed pixel points, and at this time, the camera device can determine that the first image is different from the second image, and record the first image. However, the change in pixel value may be caused by a change in color of the object or may be caused by a change in illumination of the environment in which the object is located. In order to determine whether the color of the object changes, the image capturing apparatus may not determine the determination result, and may execute step 207 and step 209 described below to continue the determination.
In step 207, the image capturing apparatus calculates a time interval between the capturing time of the first image and the capturing time of the second image.
In step 208, the image pickup apparatus determines whether the time interval is greater than a second preset time period, and if so, performs step 209, and if not, performs step 211.
In the shooting process, the camera device judges whether a first image shot at present and a second image recorded at last are the same every first preset time length, so as to determine whether the first image is recorded, and as time goes on, when the first image is acquired, the time interval between the current time point and the shooting time of the second image recorded at last may be equal to the first preset time length or greater than the first preset time length. If the color of the object is changed in the time interval, the larger the time interval between the first image and the second image is, the larger the difference between the first image and the second image is, and accordingly, whether the color of the object is changed can be judged according to the difference between the first image and the second image and the time interval between the shooting times.
For this reason, the image capturing apparatus may determine a second preset time length in advance, where the second preset time length is greater than the first preset time length, and the second preset time length may be an integral multiple of the first preset time length, which is not limited in this embodiment. The image pickup apparatus may acquire the shooting time of the first image and the shooting time of the second image, calculate a time interval between the shooting time of the first image and the shooting time of the second image, and determine whether the time interval is greater than the second preset duration.
If the time interval is not greater than the second preset time, the camera device may consider that the time interval between the first image and the second image is short, and it is difficult to accurately determine whether the first image and the second image are the same.
If the time interval is greater than the second preset time period, the image capturing apparatus may perform the following step 209 of determining the first image and the second image.
In step 209, the image pickup apparatus determines whether the pixel value change rate of each pixel point is smaller than a second preset threshold, if so, step 211 is executed, and if not, step 210 is executed.
The time interval between the first image and the second image is greater than the second preset time, and the camera device can determine whether the pixel value change rate of each pixel point is less than a second preset threshold value. The second preset threshold is used to specify a pixel value change rate of pixel points of different images in a time interval greater than the second preset duration, and may be determined according to a general change condition of an object in the second preset duration, which is not limited in this embodiment.
If the pixel value change rate of each pixel point is smaller than a second preset threshold value, which indicates that the pixel value of the pixel point is not changed greatly and the change of the image is still not obvious from the second image to the first image within the second preset time, the first image and the second image are considered to be the same, and the recording of the first image is cancelled.
And if the pixel value change rate of any pixel point is not less than the second preset threshold value, indicating that the pixel value of the pixel point is changed greatly and the change of the image is obvious from the second image to the first image within the second preset time, determining that the first image is different from the second image, and recording the first image.
It should be noted that, in this embodiment, the case that the image capturing apparatus calculates the pixel value change rate of the pixel point is taken as an example for description, actually, the image capturing apparatus may also adopt other algorithms to calculate the similarity between the first image and the second image, and determine whether the first image is the same as the second image according to the similarity. For example, the image capturing apparatus calculates a similarity between the first image and the second image by using a first similarity algorithm, determines whether the similarity is greater than a first similarity threshold, indicates that the first image is different from the second image if the similarity is not greater than the first similarity threshold, determines whether a time interval between a shooting time of the first image and a shooting time of the second image is greater than a second preset time duration if the similarity is greater than the first similarity threshold by using a second similarity algorithm, determines whether the similarity is greater than a second similarity threshold if the similarity is greater than the second similarity threshold, and records the first image if the similarity is not greater than the second similarity threshold and indicates that the first image is different from the second image. The first similarity algorithm and the second similarity algorithm have different accuracies and may reflect different accuracies between images, the first similarity threshold may be determined according to the first similarity algorithm, and the second similarity threshold may be determined according to the second similarity algorithm, which is not limited in this embodiment.
In step 210, the image capturing apparatus determines that the first image is different from the second image, records the first image, and continues to perform step 202 until the shooting process is completed.
In step 211, the image capturing apparatus determines that the first image is the same as the second image, cancels recording of the first image, and continues to perform step 202 until the shooting process is completed.
When the image pickup apparatus determines that the first image is different from the second image, the image pickup apparatus records the first image in order to record details of the change of the object in detail. And when the image pickup apparatus determines that the first image is the same as the second image, the image pickup apparatus cancels recording of the first image in order to ignore the image when the object is unchanged to highlight the details when the object is changed. Thereafter, the image pickup apparatus may continue to execute 202 to acquire the next frame image until the plural frames of images can be recorded when the photographing process is completed.
After the camera device records the multi-frame images, the multi-frame images can be played according to a preset playing time interval and the sequence of recording the multi-frame images, wherein the preset playing time interval is smaller than the first preset duration, so that the multi-frame images can be played at a faster frame rate, and the process of slowly changing the object can be rapidly presented. Of course, the camera device may also send the recorded multiple frames of images to the terminal, and the terminal plays the multiple frames of images according to the preset playing time interval and the sequence of recording the multiple frames of images, or the terminal generates a video file including the multiple frames of images according to the preset playing time interval and the sequence of recording the multiple frames of images, and plays the video file, which is not limited in this embodiment.
For example, referring to fig. 3, the first preset time period is t0, and the second preset time period is 2t0, during shooting, the image capturing apparatus may perform the following steps:
(1) at time 0, the image pickup apparatus starts capturing an image I1, and records an image I1;
(2) at time t0, the imaging apparatus acquires image I2, extracts the last frame of recorded image, i.e., image I1, performs image segmentation on images I1 and I2, determines that the segmentation line of image I1 does not match the segmentation line of image I2, determines that image I2 is different from image I1, and records image I2.
(3) At time 2t0, the image pickup device acquires an image I3, extracts a last recorded frame of image, namely an image I2, performs image segmentation on the images I2 and I3, determines that a segmentation line of the image I2 is matched with a segmentation line of the image I3, calculates a pixel value change rate between each pixel point of the image I2 and a corresponding pixel point in the image I3, determines whether the pixel value change rate of each pixel point is smaller than a first preset threshold, determines that the image I2 is the same as the image I3 if the image pickup device determines that the pixel value change rate of each pixel point is smaller than the first preset threshold, and cancels recording of the image I3.
(4) At the time 3t0, the image pickup device acquires an image I4, at this time, a recorded last frame of image, namely an image I2, is extracted, image segmentation is performed on the images I2 and I4, it is determined that a segmentation line of the image I2 matches a segmentation line of an image I4, a pixel value change rate between each pixel point of the image I2 and a corresponding pixel point in the image I4 is calculated, whether the pixel value change rate of each pixel point is smaller than a first preset threshold value is judged, if the image pickup device determines that the pixel value change rate of any pixel point is larger than the first preset threshold value, the time interval between the image I4 and the image I2 is calculated to be 2t0 and not larger than the second preset time duration 2t0, the image I2 is determined to be the same as the image I4, and the recorded image I4 is cancelled.
(5) At the time 4t0, the camera device acquires an image I5, extracts the last recorded frame of image, namely an image I2, performs image segmentation on the images I2 and I5, determines that the segmentation line of the image I2 is matched with the segmentation line of the image I5, calculates the pixel value change rate between each pixel point of the image I2 and the corresponding pixel point in the image I5, determines whether the pixel value change rate of each pixel point is smaller than a first preset threshold, determines whether the pixel value change rate of each pixel point is smaller than a second preset threshold if the camera device determines that the pixel value change rate of any pixel point is larger than the first preset threshold, calculates the time interval between the image I5 and the image I2 to be 3t0 and larger than the second preset duration 2t0, determines whether the pixel value change rate of each pixel point is smaller than the second preset threshold, and determines that the image I5 is different from the image I2 if the pixel value change rate of any pixel point is larger than the second preset threshold, the image I5 is recorded.
In the related art, a fixed time interval is adopted to record shot images, the time interval between the images cannot be adjusted according to the actual change condition of an object, and therefore when the object does not change obviously, a plurality of unchanged images can be recorded according to the fixed time interval. When the object changes faster, the image is recorded according to the fixed time interval, so that more change details cannot be grasped, and the image shooting effect is poor.
In the embodiment, when the object does not change obviously, recording of the current image is cancelled, so that the time interval between the recorded images is larger, the storage space is saved, deletion of the image without change is not needed, and when the object changes obviously, the current image is recorded, so that the time interval between the recorded images is smaller, the change details of the object are highlighted, and the image shooting effect is improved.
According to the method provided by the embodiment, when the currently shot first image is different from the currently recorded last frame image, the first image is recorded, and when the currently shot first image is the same as the currently recorded last frame image, the recording of the first image is cancelled, so that the currently shot image can be recorded only when the difference between the images is large, so that the camera device can dynamically adjust the time interval between the recorded images according to the actual change condition of the object, namely when the object changes slowly, the time interval between the images is large, when the object changes quickly, the time interval between the images is small, and when the images are played subsequently, the change details of the object can be presented in detail without deleting the images with slow changes of the object, all the images are not required to be recorded, and the storage space of the images is saved.
