Imaging device, method and computer readable medium

An imaging method comprising:

• continuously capturing, one frame at a time, a same object of imaging from a plurality of different viewpoints respectively by a plurality of imaging units;
• detecting a subject from respective images of the frames captured by any one of the imaging units;
• in a case in which a plurality of subjects are detected, computing values relating to distances between the respective detected subjects and the imaging units, and computing a range represented by a difference between a maximum value and a minimum value of the values;
• in a case in which a difference between a computed range of a specific frame, and a range of a frame that has been captured one before or after the specific frame, exceeds a predetermined threshold value, adjusting the range of the specific frame such that the difference becomes smaller;
• on the basis of a predetermined relationship between ranges and parallax amounts corresponding to the ranges, computing a parallax amount that corresponds to the computed range or the adjusted range;
• and
• recording the respective images of the frames captured by the respective imaging units, and the computed parallax amounts, in correspondence with one another on a recording unit.

A non-transitory computer readable medium which stores a program for causing a computer to function as:

• an imaging control unit that respectively controls a plurality of imaging units to continuously capture, one frame at a time, a same object of imaging from a plurality of different viewpoints respectively;
• a detecting unit that detects a subject from respective images of the frames captured by any one of the imaging units;
• a range computing unit that, in a case in which a plurality of subjects are detected by the detecting unit, computes values relating to distances between the respective detected subjects and the imaging units, and computes a range represented by a difference between a maximum value and a minimum value of the values;
• an adjusting unit that, in a case in which a difference between a range of a specific frame that has been computed by the range computing unit, and a range of a frame that has been captured one before or after the specific frame, exceeds a predetermined threshold value, adjusts the range of the specific frame such that the difference becomes smaller;
• a parallax amount computing unit that, on the basis of a predetermined relationship between ranges and parallax amounts corresponding to the ranges, computes a parallax amount that corresponds to the range computed by the range computing unit or the range adjusted by the adjusting unit;
• and
• a recording control unit that effects control so as to record the respective images of the frames captured by the respective imaging units, and the parallax amounts computed by the parallax amount computing unit, in correspondence with one another on a recording unit.
