Control apparatuses, photographing apparatuses, movable objects, control methods, and programs

A photographing system, comprising:

• a ranging sensor to measure distances of each to-be-photographed objects associated with each of a plurality of regions, wherein the plurality of to-be-photographed objects include a first target object, the first target object is associated with a first region and a first distance;
• a photographing apparatus to perform focus control based on the distances;
• and
• a control apparatus, including:
• a circuit configured to:
• cause the photographing apparatus to perform focus control on the first target object based on the first distance,
• control the photographing apparatus to obtain a plurality of images, and
• determine, based on the plurality of images, whether a second target object is in the first region, the second target object being a moving object in the first region;
• and
• cause the photographing apparatus to perform different focus controls on the first region based on whether or not the second target object is present in the first region.

A method for controlling a photographing system, wherein the photographing system comprises:

• a ranging sensor to measure distances of each to-be-photographed objects associated with each of a plurality of regions, wherein the plurality of to-be-photographed objects include a first target object, the first target object is associated with a first region and a first distance;
• and
• a photographing apparatus to perform focus control based on the distances,
• wherein the control method comprises:
• causing the photographing apparatus to perform focus control on the first target object based on the first distance,
• controlling the photographing apparatus to obtain a plurality of images,
• determining, based on the plurality of images, whether a second target object is in the first region, the second target object being a moving object in the first region, and
• causing the photographing apparatus to perform different focus controls on the first region based on whether or not the second target object is present in the first region.
