Abstract
A control apparatus includes: a determination unit configured to determine a target region; an output unit configured to output a predetermined light to the target region; a detection unit configured to detect intrusion of an object to the target region by detecting the predetermined light, wherein, in accordance that the intrusion of an object to the target region is detected by the detection unit in a state of outputting the predetermined light to a first region, the determination unit is further configured to determine a second region as the target region wherein the second region is larger than the first region.
Claims13
A control apparatus comprising:
- a determination unit configured to determine a target region;
- an output unit configured to output a predetermined light to the target region;
- a detection unit configured to detect intrusion of an object to the target region by detecting the predetermined light,
- wherein, in accordance that the intrusion of an object to the target region is detected by the detection unit in a state of outputting the predetermined light to a first region, the determination unit is further configured to determine a second region as the target region wherein the second region is larger than the first region.
A control method comprising:
- determining a target region;
- outputting a predetermined light to the target region;
- detecting intrusion of an object to the target region by detecting the predetermined light;
- and
- in accordance that the intrusion of an object to the target region is detected by the detection unit in a state of outputting the predetermined light to a first region, determining a second region as the target region wherein the second region is larger than the first region.
A non-transitory computer readable medium that stores a program, wherein the program causes a computer to execute:
- a control method comprising:
- determining a target region of predetermined light;
- outputting a predetermined light to the target region;
- detecting intrusion of an object to the target region by detecting the predetermined light;
- and
- in accordance that the intrusion of an object to the target region is detected by the detection unit in a state of outputting the predetermined light to a first region, determining a second region as the target region wherein the second region is larger than the first region.
