Video compression apparatus and video compression program

A video compression apparatus for compressing video data as a series of frames outputted from an imaging element that has a plurality of imaging regions for imaging a subject and for which imaging conditions can be set for the respective imaging regions, comprising:

• a setting unit configured to set a search region for detecting a specific region within a reference frame based on at least one of the plurality of imaging conditions set to the imaging element;
• and
• a detection unit configured to detect, based on a compression target region having a frame different from the reference frame, the specific region from the search region set by the setting unit.

A video compression program for causing a processor to execute the compression of video data as a series of frames outputted from an imaging element that has a plurality of imaging regions for imaging a subject and for which imaging conditions can be set for the respective imaging regions,

• to set a search region for detecting a specific region within a reference frame based on at least one of the plurality of imaging conditions set to the imaging element;
• and
• to detect, based on a compression target region having a frame different from the reference frame, the specific region from the search region set by the setting unit.
