and one or more processors executing the instructions to: detect objects from an image; determine a plurality of objects according to positions of the detected objects; integrate the determined plurality of objects; and generate metadata including information regarding an integrated object, wherein, in a case where a first object and a second object are detected from the image and in a case where the first object and the second object are integrated, the metadata includes an index of the first object, an index of the second object, an index of the integrated object and position information indicating a position on the integrated object, but the metadata does not include position information indicating a position on the first object and position information indicating a position on the second object. ### Claim 2 (depends on 1) The information generation apparatus according to claim 1, wherein, in a case where the plurality of objects is determined according to distances between the objects detected from the image. ### Claim 3 (depends on 1) The information generation apparatus according to claim 1, wherein the metadata is compliant with annotated region supplemental enhancement information (ARSEI). ### Claim 4 (depends on 1) The information generation apparatus according to claim 1, wherein the one or more processors further execute the instructions to determine, based on a predetermined condition, whether to enable a grouping process for grouping the detected objects. ### Claim 5 (depends on 4) The information generation apparatus according to claim 4, wherein whether to enable the grouping process is determined based on information regarding a communication band of a network. ### Claim 6 (depends on 4) The information generation apparatus according to claim 4, wherein whether to enable the grouping process is determined based on the number of objects detected from the image. ### Claim 7 (depends on 6) The information generation apparatus according to claim 6, wherein, in a case where the number of objects detected from the image is greater than or equal to a threshold, it is determined that the grouping process is to be enabled. ### Claim 8 (depends on 1) The information generation apparatus according to claim 1, wherein, in a case where the first object and the second object are detected from the image and in a case where the first object and the second object are not determined as the plurality of objects, the metadata includes the index of the first object, the index of the second object, position information indicating a position on the first object and position information indicating a position on the second object. ### Claim 9 An information generation method comprising: detecting objects from an image; determining a plurality of objects according to positions of the detected objects; integrate the determined plurality of objects; and generating metadata including information regarding an integrated object, wherein, in a case where a first object and a second object are detected from the image and in a case where the first object and the second object are integrated, the metadata includes an index of the first object, an index of the second object, an index of the integrated object and position information indicating a position on the integrated object, but the metadata does not include position information indicating a position on the first object and position information indicating a position on the second object. ### Claim 10 A non-transitory computer-readable storage medium storing a program for causing a computer to execute an information generation method comprising: detecting objects from an image; determining a plurality of objects according to positions of the detected objects; integrate the determined plurality of objects; and generating metadata including information regarding an integrated object, wherein, in a case where a first object and a second object are detected from the image and in a case where the first object and the second object are integrated, the metadata includes an index of the first object, an index of the second object, an index of the integrated object and position information indicating a position on the integrated object but the metadata does not include position information indicating a position on the first object and position information indicating a position on the second object.
