Imaging system, imaging device and program

An imaging device connectable with a portable terminal device capable of inputting a marker, comprising:

• an imaging unit that generates imaging data of video by imaging processing;
• a first clock unit that measures time;
• a storage unit that stores a video file on a basis of the imaging data in association with imaging time of the imaging data measured by the first clock unit;
• a receiving unit that receives marker time information from the portable terminal device, the marker time information containing a marker input to the video file by the portable terminal device capable of inputting a marker and input time of the marker measured by a second clock unit included in the portable terminal device in association with each other;
• a time difference detection unit that detects a time difference between time measured by the first clock unit and time measured by the second clock unit;
• and
• a correction unit that corrects the input time of the marker contained in the marker time information based on the time difference detected by the time difference detection unit and thereby generates corrected marker time information.

• and
• a playing unit that plays video on a basis of the video file based on the imaging time and the corrected marker time information.

A non-transitory computer readable medium storing a program for controlling a portable terminal device connected to an imaging device including a first clock unit that measures time, an imaging unit that generates imaging data of video by imaging processing, and a storage unit that stores a video file on a basis of the imaging data in association with imaging time of the imaging data measured by the first clock unit, the program causing a computer to execute:

• a step of inputting a marker to the video file;
• a step of measuring time by a second clock unit included in the portable terminal device;
• a step of generating marker time information containing the input marker and input time of the marker measured by the second clock unit in association with each other;
• a step of detecting a time difference between time measured by the first clock unit and time measured by the second clock unit;
• and
• a step of correcting the input time of the marker contained in the marker time information based on the detected time difference and thereby generating corrected marker time information.
