Object information extraction apparatus, object information extraction program, and object information extraction method

A non-transitory computer-readable storage medium comprising an object information extraction program for causing a computer to function as an object information extraction apparatus, the program causing the computer to perform:

• an image acquisition function of acquiring a plurality of image frames;
• a frequency determination function of acquiring frequency information including a frequency of execution of image processing, the frequency included in the frequency information being different for each of a plurality of partial areas included in the image frames, the frequency included in the frequency information indicating how many image frames among a pre-determined numbers of the image frames are to be under execution of the image processing;
• and
• an information extraction function of executing image processing for the plurality of the partial areas of the image frames at the frequency indicated by the frequency information, and extracting object information from at least one of the plurality of partial areas,
• wherein as object motion increases, the frequency at which the image processing is executed is increased.

An object information extraction method for causing a computer to function as an object information extraction apparatus, the method comprising:

• an image acquisition step of acquiring, by the computer, a plurality of image frames;
• a frequency determination step of acquiring, by the computer, frequency information including a frequency of execution of image processing, the frequency included in the frequency information being different for each of a plurality of partial areas included in the image frames, the frequency included in the frequency information indicating how many image frames among a pre-determined numbers of the image frames are to be under execution of the image processing;
• and
• an information extraction step executing image processing for the plurality of the partial areas of the image frames at the frequency indicated by the frequency information, and of extracting, by the computer, object information from at least one of the plurality of partial areas,
• wherein as object motion increases, the frequency at which the image processing is executed is increased.
