A specific example of the first person candidate point list will be described with reference to
Five entries, that is, identifiers 0 to 4 are registered in the first person candidate point list illustrated in
The five pieces of registration data (entries) are registration data corresponding to the “first person candidate point” set for the moving body determined as a person obtained by executing the flow illustrated in
Specifically, for example, it is registration data (entry) corresponding to each first person candidate point 161 illustrated in
Further, one “first person candidate point” is detected corresponding to one setting position of the divisional small region setting window, and the “first person candidate point” is also set in a plurality of windows adjacent to one window in which the “first person candidate point” is set.
Both of them may be determined to be detection points corresponding to one person detected from the image, and the “first person candidate point” at the proximity positions may be merged into one piece of data and registered in a list.
Further, as a merging technique for merging a plurality of points at adjacent coordinate positions into one point, a merging technique known from the past is applied.
