Suspicious or abnormal subject detecting device

A suspicious or abnormal subject detecting device comprising:

• an accumulating device;
• and
• a detecting device,
• wherein the accumulating device includes:
• a first obtaining unit configured to obtain a plurality of first time-series images obtained by photographing a predetermined point;
• a first detecting unit configured to detect movement of a plurality of articulations included in an action subject appeared in the plurality of first time-series images;
• and
• a determining unit configured to determine one or more of normal actions at the predetermined point based on a large number of the movement of a plurality of articulations detected by the first detecting unit,
• wherein the detecting device includes:
• a second obtaining unit configured to obtain a plurality of second time-series images obtained by photographing the predetermined point;
• a second detecting unit configured to detect movement of a plurality of articulations included in an action subject appeared in the plurality of second time-series images;
• and
• an extracting unit configured to extract, when the movement of a plurality of articulations detected by the second detecting unit is different from the normal action determined by the determining unit, an action subject which has performed an action different from the normal action from among the plurality of second time-series images,
• wherein the first detecting unit detects a plurality of articulations corresponding to articulation identification criteria for identifying a plurality of articulations of an action subject, specifies an action subject appeared in the plurality of first time-series images by specifying a plurality of articulations included in one action subject referring action subject specific criteria indicating basic postures of many variations of an action subject, ranges of movement of each articulation, and distances between each articulation in one action subject, and detects movement of the plurality of articulations included in the specified action subject,
• wherein the determining unit determines one or more of normal actions at the predetermined point based on the large number of the movement of the plurality of articulations detected by the first detecting unit,
• wherein the second detecting unit detects a plurality of articulations corresponding to articulation identification criteria for identifying a plurality of articulations of an action subject, in the plurality of second time-series images, specifies an action subject appeared in the plurality of second time-series images by specifying a plurality of articulations included in one action subject referring action subject specific criteria indicating basic postures of many variations of an action subject, ranges of movement of each articulation, and distances between each articulation in one action subject, and detects movement of the plurality of articulations included in the specified action subject, and
• wherein the extracting unit extracts, when the movement of a plurality of articulations detected by the second detecting unit is different from the normal action determined by the determining unit, an action subject which has performed an action different from the normal action from among the plurality of second time-series images.
