Image capturing system, distribution apparatus, image capturing apparatus, control method, and non-transitory computer-readable storage medium

A distribution apparatus that controls an image capturing apparatus that captures images of a plurality of resolutions at a predetermined frame rate, divides each image into tiles having a preset size, and performs intra-frame compression at a frame interval independent for each tile to output encoded data, and distributes encoded data of tiles obtained from the image capturing apparatus, as a video stream to a client on a network, the apparatus comprising:

• a distributing unit that designates a tile corresponding to a region of interest requested from a client on a network, and distributes encoded data of the designated tile as a video stream to the client;
• and
• a setting unit that sets, in the image capturing apparatus, a frame interval of intra-frame compression frames of a tile corresponding to a region of interest requested from a client on a network, such that the frame interval varies in accordance with the number of times of designation of the tile.

A method of controlling a distribution apparatus that controls an image capturing apparatus that captures images of a plurality of resolutions at a predetermined frame rate, divides each image into tiles having a preset size, and performs intra-frame compression at a frame interval independent for each tile to output encoded data, and distributes encoded data of tiles obtained from the image capturing apparatus, as a video stream to a client on a network, the method comprising:

• (a) designating a tile corresponding to a region of interest requested from a client on a network, and distributing encoded data of the designated tile as a video stream to the client;
• and
• (b) setting, in the image capturing apparatus, a frame interval of intra-frame compression frames of a tile corresponding to a region of interest requested from a client on a network, such that the frame interval varies in accordance with the number of times of designation of the tile.

A non-transitory computer-readable storage medium storing a program which causes a computer to execute the steps of a method of controlling a distribution apparatus that controls an image capturing apparatus that captures images of a plurality of resolutions at a predetermined frame rate, divides each image into tiles having a preset size, and performs intra-frame compression at a frame interval independent for each tile to output encoded data, and distributes encoded data of tiles obtained from the image capturing apparatus, as a video stream to a client on a network, the method comprising:

• (a) designating a tile corresponding to a region of interest requested from a client on a network, and distributing encoded data of the designated tile as a video stream to the client;
• and
• (b) setting, in the image capturing apparatus, a frame interval of intra-frame compression frames of a tile corresponding to a region of interest requested from a client on a network, such that the frame interval varies in accordance with the number of times of designation of the tile.
