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.

Claims (43)

1. An information processing apparatus, comprising:

a computer executing instructions that, when executed by the computer, cause the computer to function as:

an image obtaining unit configured to obtain an image captured by an imaging unit;

a setting unit configured to set a maximum size and a minimum size for detecting an object whose size is between the maximum size and the minimum size from the image;

a display control unit configured to cause a display unit to display the image on which both of a first guide representing the maximum size and a second guide representing the minimum size are superimposed;

an obtaining unit configured to obtain zoom information related to zoom magnification of the imaging unit; and

a control unit configured to change the maximum size and the minimum size, in accordance with a change in the zoom magnification based on the zoom information for detecting an object whose size is between a changed maximum size and a changed minimum size.

2. The information processing apparatus according to claim 1 ,

wherein in a case where the maximum size and the minimum size are changed in accordance with the change in the zoom magnification, the display controlling unit configured to cause the display unit to display the image on which the first guide representing the changed maximum size and the second guide representing the changed minimum size are superimposed.

3. The information processing apparatus according to claim 1 , wherein a shape of each of the first guide and the second guide is a rectangle.

4. The information processing apparatus according to claim 1 , further comprising a detection unit configured to detect an object whose size is between the maximum size and the minimum size.

5. The information processing apparatus according to claim 1 ,

wherein in a case where the zoom magnification of the imaging unit increases, the control unit configured to change the maximum size and the minimum size such that the maximum size and the minimum size increases.

6. The information processing apparatus according to claim 3 ,

wherein in a case where the maximum size and the minimum size are increased by the control unit, a size of each of the first guide and the second guide superimposed on the displayed image increases.

7. The information processing apparatus according to claim 1 ,

wherein in a case where the zoom magnification of the imaging unit decreases, the control unit configured to change the maximum size and the minimum size such that the maximum size and the minimum size decreases.

8. The information processing apparatus according to claim 5 ,

wherein in a case where the maximum size and the minimum size are decreased by the control unit, a size of each of the first guide and the second guide superimposed on the displayed image decreases.

9. An information processing method, comprising:

obtaining an image captured by an imaging unit;

setting a maximum size and a minimum size for detecting an object whose size is between the maximum size and the minimum size from the image;

causing a display unit to display the image on which both of a first guide representing the maximum size and a second guide representing the minimum size are superimposed;

obtaining zoom information related to zoom magnification of the imaging unit; and

changing the maximum size and the minimum size, in accordance with a change in the zoom magnification based on the zoom information for detecting an object whose size is between a changed maximum size and a changed minimum size.

10. The information processing method according to claim 9 ,

wherein in a case where the maximum size and the minimum size are changed in accordance with the change in the zoom magnification, the causing causes the display unit to display the image on which the first guide representing the changed maximum size and the second guide representing the changed minimum size are superimposed.

11. The information processing method according to claim 9 , wherein a shape of the first guide and the second guide is rectangle.

12. The information processing method according to claim 9 , further comprising detecting an object whose size is between the maximum size and the minimum size.

13. The information processing method according to claim 9 ,

wherein in a case where the zoom magnification of the imaging unit increases, the changing changes the maximum size and the minimum size such that the maximum size and the minimum size increases.

14. The information processing method according to claim 11 ,

wherein in a case where the maximum size and the minimum size are increased in the changing, a size of each of the first guide and the second guide superimposed on the displayed image increases.

15. The information processing method according to claim 9 ,

wherein in a case where the zoom magnification of the imaging unit decreases, the changing changes the maximum size and the minimum size such that the maximum size and the minimum size decreases.

16. The information processing method according to claim 13 ,

wherein in a case where the maximum size and the minimum size are decreased in the changing, a size of each of the first guide and the second guide superimposed on the displayed image decreases.

17. A non-transitory computer-readable storage medium storing a program for causing a computer to execute a method comprising:

obtaining an image captured by an imaging unit;

setting a maximum size and a minimum size for detecting an object whose size is between the maximum size and the minimum size from the image;

causing a display unit to display the image on which both of a first guide representing the maximum size and a second guide representing the minimum size are superimposed;

obtaining zoom information related to zoom magnification of the imaging unit; and

changing the maximum size and the minimum size, in accordance with a change in the zoom magnification based on the zoom information for detecting an object whose size is between a changed maximum size and a changed minimum size.
