Abstract
There is provided an information processing apparatus that includes an image acquisition unit that acquires a captured image, a key information acquisition unit that acquires key information for extracting a light temporal modulation component included in the captured image, and a modulation component extraction unit that extracts the modulation component from the captured image based on the key information.
Claims8
An information processing apparatus, comprising:
- a central processing unit (CPU) configured to:
- acquire a captured image from an imaging device, wherein
- the captured image includes
- a light temporal modulation component,
- a first region captured during a first light exposure time, and
- a second region captured during a second light exposure time,
- the second light exposure time is different from the first light exposure time, and
- the first region and the second region are arrayed over an entire area of the captured image;
- acquire, from the captured image, key information that comprises first information and second information, wherein
- the first information is associated with control of the imaging device, and
- the second information indicates at least one of the first light exposure time or the second light exposure time;
- and
- extract the light temporal modulation component from the captured image based on the acquired key information.
