Display control device, imaging device, display control method, and display control program

A display control method of motion picture data, the method comprising:

• a specific image insertion control step of performing an insertion control of displaying a specific image different from the motion picture data on a display unit in a period between displaying a first frame of the motion picture data on the display unit and displaying a second frame subsequent to the first frame of the motion picture data;
• and
• an insertion execution control step of deciding whether or not to execute the insertion control based on a moving amount of a moving object included in the motion picture data and an observation angle of one pixel of the motion picture data displayed on the display unit,
• wherein the observation angle and the moving amount are calculated based on a resolution of the motion picture data, a resolution of the display unit, and a viewing angle of the display unit by an observer of the display unit,
• the observation angle is an angle formed by two straight lines connecting both ends of each display pixel of the display unit in a horizontal direction or a vertical direction and eyes of the observer,
• the viewing angle is an angle formed by two straight lines connecting the eyes of the observer and both ends of a display surface of the display unit in the horizontal direction or the vertical direction, and
• the moving amount is a moving angle of a line of sight in the horizontal direction or the vertical direction in one frame of the observer who observes the moving object.

A non-transitory computer readable medium storing a display control program that causes a computer to execute processing including deciding whether or not to perform an insertion control of displaying a specific image different from motion picture data on a display unit in a period between displaying a first frame of the motion picture data on the display unit and displaying a second frame subsequent to the first frame of the motion picture data based on a moving amount of a moving object included in the motion picture data and an observation angle of one pixel of the motion picture data displayed on the display unit,

• wherein the observation angle and the moving amount are calculated based on a resolution of the motion picture data, a resolution of the display unit, and a viewing angle of the display unit by an observer of the display unit,
• the observation angle is an angle formed by two straight lines connecting both ends of each display pixel of the display unit in a horizontal direction or a vertical direction and eyes of the observer,
• the viewing angle is an angle formed by two straight lines connecting the eyes of the observer and both ends of a display surface of the display unit in the horizontal direction or the vertical direction, and
• the moving amount is a moving angle of a line of sight in the horizontal direction or the vertical direction in one frame of the observer who observes the moving object.
