An image processing includes: a unit that calculates a feature amount of main image data; a unit that calculates a feature amount of sub image data or resized sub image data; an adjustment unit that performs image quality adjustment on the resized sub image data so that a difference between a feature amount of the adjusted sub image data and the feature amount of the main image data is smaller than a difference between the calculated feature amount of the sub image data and the feature amount of the main image data; and a unit that generates display image data from the main image data and adjusted sub image data according to display mode information. The sub image data include plural content items. The adjustment unit updates the feature amount of the main image data used in the adjustment, at the timing of change of the content item.

Systems and methods are disclosed including techniques for rendering a 360-degree media content. Techniques disclosed include receiving a 360-degree media content and associated metadata that include a classification of a first spatial region from the received content. Techniques disclosed further include determining that a detected user movement is associated with a rendering of the first spatial region and determining whether the classification associated with the first spatial region complies with a stored user preference. If the classification violates the user preference, a path for gradually shifting the content rendering from a currently rendered spatial region to a spatial region that complies with the user preference is determined, and the received content is rendered according to the determined path.

The present disclosure generally relates to the field of camera surveillance, and in particular to a method and control unit for controlling a bitrate of a video stream captured with an image acquisition device.

Controlling or limiting visibility into particular metadata associated with the transfer of media content from a source device or system to a receiving device or system.

Disclosed is a signal processing device and an image display apparatus including the same. In the signal processing device and the image display apparatus according to the present disclosure, a High Dynamic Range (HDR) processor receives an image signal and adjust a luminance of the image signal, and a reduction unit configured to amplify the adjusted luminance of the image signal and increase a resolution of the grayscale of the image signal to generate an enhanced image signal, wherein the enhanced image signal provides an increased luminance and grayscale resolution of the image signal while maintaining high dynamic range within the displayed HDR image. Accordingly, expression of high grayscale of a received image may improve.

Examples of the disclosure relate to apparatus, methods and computer programs for enabling audio content rendering. An example apparatus comprising means for receiving a bitstream which comprises audio content; means for receiving dynamic content independent from the bitstream; means for receiving at least one instruction for the dynamic content from at least one of: the received bitstream or the received dynamic content; and means for rendering audio with a renderer based upon the audio content of the bitstream, the received dynamic content, and the at least one instruction. In an embodiment, the means for receiving the at least one instruction comprises means for determining presence the of at least one instruction for the dynamic content in the bitstream, When the bitstream does not comprise the at least one instruction for the received dynamic content, the apparatus comprising means for rendering audio with a renderer based upon the audio content of the bitstream without adapting the audio based upon the received dynamic content, When the bitstream comprises the at least one instruction for the received dynamic content, the apparatus comprising means for rendering the audio with the renderer based upon the audio content of the bitstream, the received dynamic content, and the at least one instruction. In a further embodiment, the apparatus further comprising means for determining position of audio elements in the audio scene and audio elements in the dynamic content. When the audio elements in the audio scene and the audio elements in the dynamic content are in a same acoustic environment, the apparatus comprising means for rendering audio with the renderer based upon the audio content of the bitstream without adapting the audio based upon the received dynamic content. When the audio elements in the audio scene and the audio elements in the dynamic content are not in the same acoustic environment, the apparatus comprising means for rendering the audio with the renderer based upon both the audio content of the bitstream and the received dynamic content. In an embodiment, the apparatus further comprising means for determining an anchor object in an audio scene; means for determining at least one instruction for dynamic content relative to the anchor object; and means for transmitting the audio scene in a bitstream, where the bitstream comprises the at least one instruction.
