Abstract
An image processing apparatus includes an acquisition unit configured to acquire information about field of view associated with a plurality of video data, and an extraction unit configured to extract, from video data with a wide field of view which includes an area indicated by information about the field of view of the video data displayed in timing at which an instruction for setting frame video data extracted from video data is input and is associated with the information about the field of view indicating an area wider than the area among the plurality of the video data, the frame image data corresponding to the timing.

An image processing apparatus capable of extracting frame image data from video data, wherein the video data is associated with information about the field of view of the video data, and a plurality of the video data includes video data different in information about field of view from the video data, the image processing apparatus comprising:
- an acquisition unit configured to acquire the information about field of view associated with the plurality of the video data;
- and
- an extraction unit configured to extract based on the information about the field of view acquired by the acquisition unit, from video data with a wide field of view, which includes an area indicated by information about the field of view of the video data displayed in timing at which an instruction for specifying frame video data to be extracted from video data is input, and is associated with the information about the field of view indicating an area wider than the area among the plurality of the video data, the frame image data corresponding to the timing.
An image processing apparatus capable of reproducing encoded video data in which a plurality of video data is hierarchically encoded, wherein
- the encoded video data in which a plurality of video data is hierarchically encoded has a structure for holding encoded stream data in a plurality of layers corresponding to a plurality of video data, the encoded stream data in each layer includes information about the number of pixels indicating a value of the number of pixels of frame image data composing video data corresponding to each layer, information about field of view of the video data, and information about a reference layer to which reference is made in encoding the video data and which is related to a layer corresponding to video data, video data low in resolution of frame image data composing video data in a plurality of video data is encoded in a lower layer, and video data high in resolution of frame image data composing video data is encoded in a higher layer, the image processing apparatus comprising:
- an acquisition unit configured to acquire the information about the number of pixels and field of view of the video data and the information about a reference layer from the encoded stream data in each layer;
- a determination unit configured to determine whether information about field of view of the video data corresponding to each layer is the same as the information about field of view of the video data displayed in timing at which instructions for specifying frame video data extracted from video data is input based on the information about the number of pixels and field of view and the information about the reference layer acquired by the acquisition unit;
- and
- an extraction unit configured to extract the frame image data corresponding to the timing from the video data corresponding to the layer higher than the layer corresponding to the displayed video data among the video data whose information about field of view is determined by the determination unit to be the same as the information about field of view of the displayed video data based on the information about the reference layer.
A method for controlling an image processing apparatus capable of extracting frame image data from video data, wherein the video data is associated with information about the field of view of the video data and a plurality of the video data includes video data different in information about field of view from the video data, the method comprising:
- acquiring the information about field of view associated with the plurality of the video data;
- and
- extracting, from video data with a wide field of view which includes an area indicated by information about the field of view of the video data displayed in timing at which an instruction for specifying frame video data to be extracted from video data is input and are associated with the information about the field of view indicating an area wider than the area among the plurality of the video data, the frame image data corresponding to the timing based on the acquired information about the field of view.
An image processing apparatus capable of reproducing encoded video data in which a plurality of video data is hierarchically encoded, wherein the encoded video data in which a plurality of video data is hierarchically encoded has a structure for holding encoded stream data in a plurality of layers corresponding to a plurality of video data, the encoded stream data in each layer includes information about the number of pixels indicating a value of the number of pixels of frame image data composing video data corresponding to each layer, information about field of view of the video data, and information about a reference layer to which reference is made in encoding the video data and which is related to a layer corresponding to video data, video data low in resolution of frame image data composing video data in a plurality of video data is encoded in a lower layer and video data high in resolution of frame image data composing video data is encoded in a higher layer, the method comprising:
- acquiring the information about the number of pixels and field of view of the video data and the information about a reference layer from the encoded stream data in each layer;
- determining whether information about field of view of the video data corresponding to each layer is the same as the information about field of view of the video data displayed in timing at which an instruction for specifying frame video data extracted from video data is input based on the information about the number of pixels and field of view and the acquired information about the reference layer;
- and
- extracting the frame image data corresponding to the timing from the video data corresponding to the layer higher than the layer corresponding to the displayed video data among the video data whose information about field of view is determined to be the same as the information about field of view of the displayed video data based on the information about the reference layer.
