Abstract
An apparatus includes a detection unit configured to detect a tracking target included in an angle of view based on a signal indicating a pixel position and time at which a change of luminance has occurred, an estimation unit configured to estimate movement of the detected tracking target, and a determination unit configured to determine a control value for changing the angle of view based on the estimated movement of the tracking target.
Claims17
An apparatus comprising:
- at least one processor;
- a memory coupled to the at least one processor and storing instructions that, when executed by the at least one processor, cause the at least one processor to function as:
- a detection unit configured to detect a tracking target included in an angle of view based on a signal indicating change of luminance;
- an estimation unit configured to estimate movement of the detected tracking target;
- and
- a determination unit configured to determine at least one of (i) a control value for changing a direction of the angle of view so that the tracking target is tracked at a speed faster or slower than a speed of the estimated movement of the tracking target and (ii) a control value for changing the direction of the angle of view to a direction different from a direction of the estimated movement of the tracking target.

A method comprising:
- detecting a tracking target included in an angle of view based on a signal indicating a change of luminance;
- estimating movement of the detected tracking target;
- and
- determining at least one of (i) a control value for changing a direction of the angle of view so that the tracking target is tracked at a speed faster or slower than a speed of the estimated movement of the tracking target and (ii) the control value for changing the direction of the angle of view to a direction different from a direction of the estimated movement of the tracking target.

A non-transitory computer-readable storage medium storing a program for causing a computer to execute a method, the method comprising:
- detecting a tracking target included in an angle of view based on a signal indicating a change of luminance;
- estimating movement of the detected tracking target;
- and
- determining at least one of (i) a control value for changing a direction of the angle of view so that the tracking target is tracked at a speed faster or slower than a speed of the estimated movement of the tracking target and (ii) the control value for changing the direction of the angle of view to a direction different from a direction of the estimated movement of the tracking target.
