Abstract
An information processing device including a light source control unit that controls a light source that irradiates an eye with light; and an exposure control unit that controls exposure for imaging the eye. The light source control unit sets a state of the light source to an on state or an off state at a time when the exposure is not performed.
Claims13
An information processing apparatus, comprising:
- circuitry configured to:
- control a light source that irradiates an eye with light;
- control exposure for an imaging operation of the eye;
- acquire imaging processing information comprising an exposure end time corresponding to each frame of a plurality of successive frames and an exposure start time corresponding to each frame of the plurality of successive frames, wherein the plurality of successive frames is associated with the imaging operation;
- determine the exposure end time of a first frame of a plurality of successive frames based on the imaging processing information;
- determine the exposure start time of a second frame of the plurality of successive frames based on the imaging processing information, wherein the second frame is successive to the first frame;
- and
- change a state of the light source in a time interval between the exposure end time of the first frame and the exposure start time of the second frame, wherein
- the state of the light source is one of an on state or an off state, and
- the state of the light source is changed after the exposure end time of the first frame.
