Abstract
A control apparatus and method that captures video image includes acquiring a parameter for recognition processing with respect to acquired image data and changing the acquired parameter according to a change in zoom magnification of an image capturing unit.
Claims14
A capturing apparatus comprising:
- a computer executing instructions that, when executed by the computer, cause the computer to function as:
- an acquisition unit configured to acquire a first image captured at a first zoom magnification;
- a setting unit configured to set at least one of a position and a length of a segment line in the first image for detecting an event which corresponds to passage of an object to be detected from the first image, according to a user instruction for specifying the segment line in a setting screen on which the first image is displayed;
- a control unit configured to change at least one of the position and the length of the segment line set in the first image, according to a change from the first zoom magnification to a second zoom magnification different from the first zoom magnification;
- and
- a transmission unit configured to transmit, such that the segment line at least one of the position and the length of which has been changed by the control unit is displayed in the setting screen on which a second image captured at the second zoom magnification is displayed, information to an external apparatus after the control unit has changed at least one of the position and the length of the segment line.

A control method for controlling a capturing apparatus, the control method comprising:
- obtaining a first image captured at a first zoom magnification;
- setting at least one of a position and a length of a segment line in the first image for detecting an event which corresponds to passage of an object to be detected from the first image, according to a user instruction for specifying the segment line in a setting screen on which the first image is displayed;
- changing at least one of the position and the length of the segment line set in the first image, according to a change from the first zoom magnification to a second zoom magnification different from the first zoom magnification;
- and
- transmitting, such that the segment line at least one of the position and the length of which has been changed in the changing is displayed in the setting screen on which a second image captured at the second zoom magnification is displayed, information to an external apparatus after at least one of the position and the length of the segment line has been changed in the changing.

A capturing apparatus comprising:
- a computer executing instructions that, when executed by the computer, cause the computer to function as:
- an acquisition unit configured to acquire a first image captured at a first zoom magnification;
- a setting unit configured to set at least one of a position and a size of a region in the first image for detecting an event which corresponds to intrusion of an object to be detected from the first image, according to a user instruction for specifying the region in a setting screen on which the first image is displayed;
- a control unit configured to change at least one of the position and the size of the region set in the first image, according to a change from the first zoom magnification to a second zoom magnification different from the first zoom magnification;
- and
- a transmission unit configured to transmit, such that the region at least one of the position and the size of which has been changed by the control unit is displayed in the setting screen on which a second image captured at the second zoom magnification is displayed, information to an external apparatus after the control unit has changed at least one of the position and the size of the region.
