Abstract

A transmission apparatus includes an input unit configured to input an image, a detection unit configured to detect an object from the image input by the input unit, a generation unit configured to generate a plurality of types of attribute information about the object detected by the detection unit, a reception unit configured to receive a request, with which a type of the attribute information can be identified, from a processing apparatus via a network, and a transmission unit configured to transmit the attribute information of the type identified based on the request received by the reception unit, of the plurality of types of attribute information generated by the generation unit.

Claims

1. A transmission apparatus comprising:

an input unit configured to input an image;

a detection unit configured to detect an object from the image input by the input unit;

a generation unit configured to generate a plurality of types of attribute information about the object detected by the detection unit;

a reception unit configured to receive a request, with which a type of the attribute information can be identified, from a processing apparatus via a network; and

a transmission unit configured to transmit the attribute information of the type identified based on the request received by the reception unit, of the plurality of types of attribute information generated by the generation unit.

2. The transmission apparatus according to claim 1, wherein the attribute information includes at least one of region information indicating a region of the detected object within the image, a size of the detected object within the image, and an age of the detected object.

3. The transmission apparatus according to claim 1, further comprising a second detection unit configured to detect an occurrence of a predetermined event according to a positional relationship among a plurality of objects detected from a plurality of frames of the image,

wherein the attribute information includes event information indicating that the predetermined event has occurred.

4. The transmission apparatus according to claim 1, wherein the reception unit is configured to receive type information about a type of the processing apparatus as the request with which the type of the attribute information can be identified.

5. The transmission apparatus according to claim 4, wherein the transmission unit is configured, if the type information received by the reception unit is first type information, which indicates that the processing apparatus is a type of an apparatus that does not execute image analysis, to transmit region information that indicates a region in which each of the detected images exists within the image, while if the type information received by the reception unit is second type information, which indicates that the processing apparatus is a type of an apparatus that executes image analysis, the transmission unit is configured to transmit at least one of the age or stability duration of each object together with the region information about each of the detected objects.

6. The transmission apparatus according to claim 1, wherein the request received by the reception unit includes information about the type of the attribute information to be transmitted by the transmission unit.

7. The transmission apparatus according to claim 1, further comprising a storage unit configured to store association among the plurality of types of attribute information classified into categories,

wherein the request received by the reception unit includes information about the categories, and

wherein the transmission unit is configured to transmit the attribute information of the type associated with the category indicated by the request received by the reception unit.

8. A transmission method executed by a transmission apparatus, the transmission method comprising:

inputting an image;

detecting an object from the input image;

generating a plurality of types of attribute information about the detected object;

receiving a request, with which a type of the attribute information can be identified, from a processing apparatus via a network; and

transmitting the attribute information of the type identified based on the received request, of the plurality of types of generated attribute information.

9. The transmission method according to claim 8, further comprising receiving type information about a type of the processing apparatus as the request with which the type of the attribute information can be identified.

10. The transmission method according to claim 9, further comprising:

transmitting, if the received type information is first type information, which indicates that the processing apparatus is a type of an apparatus that does not execute image analysis, region information that indicates a region in which each of the detected images exists within the image; and

transmitting, if the received type information is second type information, which indicates that the processing apparatus is a type of an apparatus that executes image analysis, at least one of an age or stability duration of each object together with the region information about each of the detected objects.

11. The transmission method according to claim 8, wherein the received request includes information about the type of the attribute information to be transmitted.

12. The transmission method according to claim 8, further comprising:

storing association among the plurality of types of attribute information classified into categories, wherein the received request includes information about the categories; and

transmitting the attribute information of the type associated with the category indicated by the received request.

13. A computer-readable storage medium storing instructions which, when executed by a computer, cause the computer to perform operations comprising:

inputting an image;

detecting an object from the input image;

generating a plurality of types of attribute information about the detected object;

receiving a request, with which a type of the attribute information can be identified, from a processing apparatus via a network; and

transmitting the attribute information of the type identified based on the received request, of the plurality of types of generated attribute information.

14. The storage medium according to claim 13, wherein the operations further comprise receiving type information about a type of the processing apparatus as the request with which the type of the attribute information can be identified.

15. The storage medium according to claim 14, wherein the operations further comprise:

transmitting, if the received type information is first type information, which indicates that the processing apparatus is a type of an apparatus that does not execute image analysis, region information that indicates a region in which each of the detected images exists within the image; and

transmitting, if the received type information is second type information, which indicates that the processing apparatus is a type of an apparatus that executes image analysis, at least one of an age or stability duration of each object together with the region information about each of the detected objects.

16. The storage medium according to claim 13, wherein the received request includes information about the type of the attribute information to be transmitted.

17. The storage medium according to claim 13, wherein the operations further comprise:

storing association among the plurality of types of attribute information classified into categories, wherein the received request includes information about the categories; and

transmitting the attribute information of the type associated with the category indicated by the received request.
