Abstract

In an information recording system, an object information acquisition unit acquires object information. An image acquisition unit acquires image information indicating a type of situation in which the object information was acquired. A recording unit records the object information, the image information, and time point information on a recording medium such that the object information, the image information, and the time point information are associated with each other. An event detection unit detects an event on the basis of at least one piece of the object information and the image information. A reading unit reads the object information and the image information associated with the time point information corresponding to an event occurrence time point from the recording medium. A display unit displays the object information and the image information such that the object information and the image information are associated with each other.

First claim

What is claimed is:

1 . An information recording system comprising:
an object information acquisition unit configured to acquire object information about an object; an image acquisition unit configured to acquire image information indicating a situation in which the object information was acquired by the object information acquisition unit; a recording unit configured to record the object information, the image information, and time point information on a recording medium such that the object information, the image information, and the time point information are associated with each other, the time point information indicating a time point at which the object information was acquired and a time point at which the image information was acquired; an event detection unit configured to detect an event on the basis of at least one piece of the object information and the image information, the event being a state in which the at least one piece of the object information and the image information recorded on the recording medium satisfies a predetermined condition; a reading unit configured to read the object information and the image information that are associated with the time point information corresponding to an event occurrence time point that is a time point at which the event occurred from the recording medium; and a display unit configured to display the object information and the image information read by the reading unit such that the object information and the image information are associated with each other.

2 . The information recording system according to claim 1 , further comprising a situation information acquisition unit configured to acquire situation information that indicates a type of situation in which the object information was acquired and is information other than the image information of the object,
wherein the recording unit records the object information, the image information, the situation information, and the time point information on the recording medium such that the object information, the image information, the situation information, and the time point information are associated with each other, the time point information indicating a time point at which the object information was acquired, a time point at which the image information was acquired, and a time point at which the situation information was acquired, and the event detection unit detects the event on the basis of at least one piece of the object information, the image information, and the situation information recorded on the recording medium, the event being a state in which the at least one piece of the object information, the image information, and the situation information recorded on the recording medium satisfies a predetermined condition.

3 . The information recording system according to claim 1 , further comprising a sound acquisition unit configured to acquire sound information based on a sound uttered by an observer who observes the object,
wherein the recording unit records the object information, the image information, the sound information, and the time point information on the recording medium such that the object information, the image information, the sound information, and the time point information are associated with each other, the time point information indicating a time point at which the object information was acquired, a time point at which the image information was acquired, and a time point at which the sound information was acquired, and the event detection unit detects the event on the basis of at least one piece of the object information, the image information, and the sound information recorded on the recording medium, the event being a state in which the at least one piece of the object information, the image information, and the sound information recorded on the recording medium satisfies a predetermined condition.

4 . The information recording system according to claim 3 ,
wherein the sound information is a time-series sound signal, the reading unit reads the sound signal from the recording medium and reads the object information and the image information that are associated with the time point information corresponding to the event occurrence time point from the recording medium, the display unit displays the sound signal read by the reading unit in a time-series graph such that a change in the sound signal over time is able to be visually recognized, the display unit displays the object information and the image information read by the reading unit such that the object information and the image information are associated with the time-series graph, and the display unit displays a position on the time-series graph at a time point corresponding to the event occurrence time point.

5 . The information recording system according to claim 1 , further comprising:
a sound acquisition unit configured to acquire sound information based on a sound uttered by an observer who observes the object; and a sound processing unit configured to convert the sound information acquired by the sound acquisition unit into text information, wherein the recording unit records the object information, the image information, the text information, and the time point information on the recording medium such that the object information, the image information, the text information, and the time point information are associated with each other, the time point information indicating a time point at which the object information was acquired, a time point at which the image information was acquired, and a time point at which the sound information that is a source of the text information was acquired, and the event detection unit detects the event on the basis of at least one piece of the object information, the image information, and the text information recorded on the recording medium, the event being a state in which the at least one piece of the object information, the image information, and the text information recorded on the recording medium satisfies a predetermined condition.

6 . The information recording system according to claim 1 , further comprising:
a sound acquisition unit configured to acquire sound information based on a sound uttered by an observer who observes the object; and a sound processing unit, wherein the recording unit records the object information, the image information, the sound information, and the time point information on the recording medium such that the object information, the image information, the sound information, and the time point information are associated with each other, the time point information indicating a time point at which the object information was acquired, a time point at which the image information was acquired, and a time point at which the sound information was acquired, the reading unit reads the sound information from the recording medium, the sound processing unit converts the sound information read by the reading unit into text information, the recording unit associates the text information with the object information, the image information, and the time point information recorded on the recording medium and records the text information on the recording medium, the time point information with which the text information is associated indicates a time point at which the sound information that is a source of the text information was acquired, and the event detection unit detects the event on the basis of at least one piece of the object information, the image information, and the text information recorded on the recording medium, the event being a state in which the at least one piece of the object information, the image information, and the text information recorded on the recording medium satisfies a predetermined con
