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

1. An information processing apparatus comprising:

a hardware processor; and

a memory for storing instructions to be executed by the hardware processor,

wherein, when the instructions stored in the memory are executed by the hardware processor, the information processing apparatus functions as;

a display controlling unit configured to cause a display unit to display, overlaid on a first image captured by a camera, a first guide representing a maximum size and a second guide representing a minimum size,

wherein each of the maximum size and minimum size is changeable based on a user operation performed while the first guide and second guide are displayed overlaid on the first image; and

a setting unit configured to set the maximum size and minimum size that have been changed,

wherein the set maximum size and minimum size are to be used for detecting an object whose size is between the set maximum size and minimum size from a second image captured by the camera at a time different from the first image.

2. The information processing apparatus according to claim 1, wherein the apparatus further functions as:

a tracking unit configured to associate, in a case where a distance between a first object detected from the first image and a second object detected from the second image is shorter than a threshold, the first object in the first image and the second object in the second image.

3. The information processing apparatus according to claim 1, wherein the display controlling unit causes the display unit to display a user interface, wherein each of the size of the first guide and the size of the second guide is changeable by dragging a border or a node thereof by using the user interface.

4. The information processing apparatus according to claim 1, wherein the object to be detected from the second image captured by the camera is an image of a human.

5. The information processing apparatus according to claim 1, wherein, when the instructions stored in the memory are executed by the hardware processor, the information processing apparatus functions as a receiving unit configure to receive operation information for setting a detection area of an object.

6. The information processing apparatus according to claim 1, wherein the first guide and the second guide are rectangular.

7. The information processing apparatus according to claim 1, wherein each of the first image and second image are image frames forming a moving image.

8. The information processing apparatus according to claim 1,

wherein the information processing apparatus functions as a control apparatus external to the camera, and

wherein the setting unit sets the maximum size and minimum size to the camera, in response to the user operation.

9. The information processing apparatus according to claim 1, wherein each of the maximum size and minimum size is changeable by dragging a border or a node of the respective guide by the user operation.

10. A computer-implemented information processing method comprising:

reading out from a memory instructions stored therein to be executed by a hardware processor,

wherein, when the instructions stored in the memory are executed by the hardware processor, the hardware processor performs functions comprising;

displaying, overlaid on a first image captured by a camera, a first guide representing a maximum size and a second guide representing a minimum size,

wherein each of the maximum size and minimum size is changeable based on a user operation performed while the first guide and second guide are displayed overlaid on the first image; and

setting the maximum size and minimum size that have been changed,

wherein the set maximum size and minimum size are to be used for detecting an object whose size is between the set maximum size and minimum size from a second image captured by the camera at a time different from the first image.

11. The computer-implemented information processing method according to claim 10, further comprising:

tracking a first object detected from the first image and a second object detected from the second image, and

associating, in a case where a distance between the first object detected from the first image and the second object detected from the second image is shorter than a threshold, the first object in the first image and the second object in the second image.

12. The computer-implemented information processing method according to claim 10, further comprising:

displaying a user interface, wherein each of the size of the first guide and the size of the second guide is changeable by dragging a border or a node thereof by using the user interface.

13. The computer-implemented information processing method according to claim 10, wherein the object to be detected from the second image captured by the camera is an image of a human.

14. The computer-implemented information processing method according to claim 10, further comprising:

receiving operation information for setting a detection area of an object.

15. The computer-implemented information processing method according to claim 10, wherein the first guide and the second guide are rectangular.

16. A non-transitory computer-readable medium storing computer executable instructions for causing a computer to execute an information processing method comprising:

displaying, overlaid on a first image captured by a camera, a first guide representing a maximum size and a second guide representing a minimum size,

wherein each of the maximum size and minimum size is changeable based on a user operation performed while the first guide and second guide are displayed overlaid on the first image; and

setting the maximum size and the minimum size that have been changed,

wherein the set maximum size and minimum size are to be used for detecting an object whose size is between the set maximum size and minimum size from a second image captured by the camera at a time different from the first image.

17. The non-transitory computer-readable medium according to claim 16, wherein the method further comprises:

tracking a first object detected from the first image and a second object detected from the second image, and

associating, in a case where a distance between the first object detected from the first image and the second object detected from the second image is shorter than a threshold, the first object in the first image and the second object in the second image.

18. The non-transitory computer-readable medium according to claim 16, wherein the method further comprises:

displaying a user interface, wherein each of the size of the first guide and the size of the second guide is changeable by dragging a border or a node thereof by using the user interface.

19. The non-transitory computer-readable medium according to claim 16, wherein the object to be detected from the second image captured by the camera is an image of a human.

20. The non-transitory computer-readable medium according to claim 16, wherein the method further comprises receiving operation information for setting a detection area of an object.

21. The non-transitory computer-readable medium according to claim 16, wherein the first guide and the second guide are rectangular.
