Patent ID: 8634473

Claim:
An image processing apparatus that outputs encoded image data which has been hierarchically-encoded to a display apparatus which is connected thereto in a communicatable manner, the image processing apparatus comprising: an acquisition unit configured to acquire display resolution information of a display unit of the display apparatus; a determination unit configured to determine whether a field of view of the high-resolution layer is wider than a field of view of the base layer if a high-resolution layer with a resolution equal to or higher than the base layer exists according to layer resolution information of each of a plurality of layers and field of view information of each of the plurality of layers, adopting a layer corresponding to image data having a resolution equal to a display resolution of the display unit or a layer corresponding to image data having a resolution closest to the display resolution of the display unit, among image data corresponding to each of the plurality of layers contained in encoded image data to be transferred to the display apparatus, as a base layer; a conversion unit configured to, in a case where the determination unit determines that a field of view of a high-resolution layer is wider than a field of view of the base layer if the high-resolution layer with a resolution equal to or higher than the base layer exists, perform resolution conversion processing to the high-resolution layer to render image data corresponding to the high-resolution layer at least equal to or less than the display resolution; a coding unit configured to perform hierarchical coding on image data corresponding to the high-resolution layer subjected to resolution conversion processing by the conversion unit, and image data corresponding to each of a plurality of layers other than the high-resolution layer; and an output unit configured to output encoded image data which has been encoded by the coding unit to the display apparatus, wherein the conversion unit does not perform the resolution conversion processing, in a case where the determination unit determines that a field of view of a high-resolution layer is equal to or lower than a field of view of the base layer if the high-resolution layer with a resolution equal to or higher than the base layer exists.
