For example, the step S10 includes: when detecting an object motion trajectory shooting instruction, the terminal displays an object motion scene selection interface, so that the user selects a corresponding object motion scene based on the object motion scene selection interface displayed by the terminal; When the user selects a selection instruction triggered by the object motion scene selection interface, the terminal locks an object motion scene corresponding to the selection instruction, and adjusts a corresponding shooting parameter based on the locked object motion scene; Take a picture with the exposure time set.

The object motion trajectory shooting instruction may be triggered based on a physical shooting button, a virtual shooting button, a voice, a gesture, and a control command sent by a third-party control terminal on the terminal. When the terminal detects the motion track shooting instruction of the object, the terminal may immediately start taking a picture, or The preset preset duration starts to take a picture; wherein the delaying the preset duration to start taking the picture is advantageous to avoid taking a picture when the user shakes the mobile phone by pressing the shooting button or triggering the virtual shooting button.

In step S20, the terminal determines whether a preset flag bit is set in the preset storage path.

The flag bit is configured to indicate that there may be an interruption in the picture data during the shooting process, and the flag bit can be set by the user or the developer.

Step S30: When it is determined that the flag is set in the preset storage path, the terminal combines the captured picture with the object motion track picture before the flag bit to generate an object motion track video.

In this embodiment, when the flag is set in the preset storage path, the terminal combines the captured picture with the object motion track picture before the flag bit to generate an object motion track video. Ways include:

Step S33, at the end of the shooting, the terminal stores the synthesized plurality of object motion track pictures to the preset storage path and based on the plurality of object motion track pictures synthesized during the shooting process, and before the flag bit The object motion trajectory image generates an object motion trajectory video.

2) Referring to FIG. 3, FIG. 3 is a schematic diagram of the refinement process of the second embodiment of step S30. In this embodiment, step S30 includes:

Step S34, determining that a flag is set in the preset storage path, at the end of shooting, The terminal sorts the captured pictures according to the shooting time, and extracts the captured pictures according to the arrangement order;

Step S35, the terminal uses the last object motion track picture before the flag bit as the first synthesized object motion track picture;

Step S36, the terminal combines the extracted picture with the last synthesized object motion track picture to generate a new object motion track picture every time a picture is extracted;

The manners of generating the motion trajectory video of the object listed above are merely exemplary. Those skilled in the art utilize the technical idea of the present invention, and other methods for generating motion trajectories of the object according to the specific needs thereof are all in the present invention. Within the scope of protection, it is not exhaustive here.

In this embodiment, after the first picture is captured, the method for synthesizing the first picture captured by the terminal and the last object motion track picture before the previously captured flag may be: The picture pixel and the pixel of the last object motion track picture before the flag bit are superimposed to generate a picture to be synthesized; or, according to the brightness value information of the pixel in the first picture and the last object motion track picture before the flag bit The brightness value information of the middle pixel generates a picture to be synthesized.

It can be understood by those skilled in the art that, in order to improve the accuracy of the image synthesis during the shooting process of the object, when the flag is set in the preset storage path, the terminal displays the selection interface for the user to select whether Generating an object motion trajectory picture or video based on the previously taken picture; when detecting an instruction to generate an object motion trajectory video based on the previous picture, the terminal will capture the first picture before the previously captured flag The last object motion track picture is synthesized as the picture to be combined.

In this embodiment, a new object motion trajectory picture may be generated by performing pixel superposition or pixel replacement in the image synthesis. In this embodiment, a preferred scheme may generate a new object motion trajectory image for pixel replacement. As follows: determining whether the brightness value of the pixel in the picture captured at the same position is greater than the brightness value of the pixel of the last synthesized object motion track picture; determining that the brightness value of the pixel in the picture captured at the same position is greater than the last synthesized When the brightness value of the pixel of the object motion track picture is used, the pixel in the last synthesized object motion track picture is replaced with the pixel corresponding to the position in the captured picture, and a new object motion track picture is generated.

2) The terminal triggers the interrupt request when the remaining storage space of the terminal is less than a preset storage space threshold.

During the shooting process of the object motion track, the remaining storage space of the terminal may be detected in real time or periodically, and the interrupt request may be triggered when the remaining storage space of the terminal is less than the preset storage space threshold.

The two methods for triggering the interrupt request listed above are merely exemplary. Those skilled in the art may use the technical idea of the present invention to trigger the interrupt request according to other manners of the specific needs thereof. Within the scope of protection, it is not exhaustive here.

In this embodiment, a preferred scheme may generate a new object motion trajectory image for pixel replacement. As follows: determining whether the brightness value of the pixel in the picture extracted by the same position is greater than the brightness value of the pixel of the last synthesized object motion track picture; determining the brightness value of the pixel in the picture extracted at the same position is greater than the last synthesized When the brightness value of the pixel of the object motion track picture is the motion track of the object synthesized last time The pixels in the slice are replaced with pixels of corresponding positions in the captured picture, and a new object motion track picture is generated.
