Definitions

  • the present invention relates to a technique for synchronizing images taken by a plurality of devices.
  • Patent Document 1 describes a method of detecting a signal, determining the amount of deviation between images, and performing alignment.
  • Patent Document 1 it is necessary to capture a signal phenomenon (for example, the movement or sound of a clapperboard) with all the photographing devices.
  • a signal phenomenon for example, the movement or sound of a clapperboard
  • the device cannot be used in scenes where it is difficult to give a signal, such as a concert or a recital.
  • the present invention has been made in consideration of the above problems, and an object of the present invention is to provide a technique for synchronizing between captured images in a system for photographing a recording target using a plurality of photographing devices.
  • the first photographing device and the second photographing device are both devices for photographing an object.
  • the first photographing device acquired the first elapsed time indicating the elapsed time from the start of recording, and requested the second photographing device to transmit the second elapsed time, which was obtained. Compare the elapsed time with the first elapsed time. Further, the time required for the inquiry is used to calculate the shift time (offset time) between the moving images.
  • the transmission request for the elapsed time can be made at any time when the first and second photographing devices are recording. For example, it may be executed at the start of recording, or may be executed periodically during recording.
  • the generation step of synchronizing the first moving image and the second moving image by using the offset time and synthesizing the synchronized moving images to generate a third moving image is further included. It may be characterized by that.
  • the first shooting is based on the second acquisition step of acquiring the time required to receive the second elapsed time, the first elapsed time, the second elapsed time, and the required time.
  • the own device executes the calculation step of calculating the offset time for synchronizing the first moving image recorded by the device and the second moving image recorded by the second photographing device.
  • the transmission step of acquiring the second elapsed time and transmitting the second elapsed time to the first photographing device is executed in response to the request.
  • problems in shooting a performance with a plurality of devices will be described with reference to FIG. 3 (A).
  • One of the problems is that the timing at which each shooting device starts recording is not the same.
  • the illustrated video source A starts at time 1, but the video source B starts at the timing when time 1 has passed. That is, the heads of the video source A and the video source B do not match. This is because the timing at which the photographing devices start recording does not match each other. If editing is performed without matching the times, the timings of the images do not match each other, causing problems such as giving the viewer a sense of discomfort.
  • the information processing device 100 includes a control unit 101, an auxiliary storage device 102, a main storage device 103, an input / output unit 104, a camera 105, a microphone 106, and a communication unit 107. These means are driven by power supplied by a rechargeable battery.
  • the control unit 101 is an arithmetic unit that controls the control performed by the information processing device 100.
  • the control unit 101 is composed of, for example, a CPU (Central Processing Unit) or the like. Specifically, the control unit 101 performs a process of recording an object using the camera 105 and the microphone 106, which will be described later. Further, the control unit 101 processes to acquire the elapsed time (time stamp) from the start of recording, and the video sources acquired by the plurality of information processing devices 100 based on the time stamps acquired from the plurality of information processing devices 100. Executes processing such as calculating the offset time. Details of the processing will be described later with reference to the drawings.
  • a CPU Central Processing Unit
  • the communication unit 107 is an interface for wirelessly communicating with another information processing device 100.
  • the communication unit 107 is configured to be capable of transmitting and receiving data to and from another information processing device 100 according to wireless communication standards such as IEEE802.11 and Bluetooth (registered trademark).
  • the control unit 101 changes the operation content depending on whether the information processing device 100 operates as a master device or a slave device.
  • the user of the information processing device 100 specifies in advance whether to operate the device as a master device or a slave device. Further, at this time, the master device and the slave device may be paired.
