A filtered image with enhanced image quality is output. Provided is a loop filter including: a filtering processing unit configured to apply a filter to an unfiltered image; and an ALF unit configured to receive input of a DL image to which a filter is applied by a first filtering processing unit out of the filtering processing unit. The ALF unit further receives input of the unfiltered image.

Image filtering apparatus, image decoding apparatus, and image coding apparatus

To apply a filter to input image data in accordance with an image characteristic. A CNN filter includes a neural network configured to receive an input of one or multiple first type input image data and one or multiple second type input image data, and output one or multiple first type output image data, the one or multiple first type input image data each having a pixel value of a luminance or chrominance, the one or multiple second type input image data each having a pixel value of a value corresponding to a reference parameter for generating a prediction image and a differential image, the one or multiple first type output image data each having a pixel value of a luminance or chrominance.

An image decoding apparatus includes a decoding unit configured to decode coded data into a decoded image and segmentation metadata, a segmentation metadata decoding unit configured to generate segmentation information, and an image processing unit configured to perform prescribed image processing on the decoded image with reference to the segmentation information.

An image quality/rate control portionconfirms whether a predictive code amount Ci is a target code amount Rt or less. When the predictive code amount Ci is the target code amount Rt or less, the predictive code amount Ci is output to a base layer coding portion. Then, a switchis turned off. When the predictive code amount Ci exceeds the target code amount Rt, the target code amount Rt is output to the base layer coding portion. Then, the switchis turned on and (predictive code amount Ci&#x2212;target code amount Rt) is output to an enhancement layer coding portion. A bufferstores coded data of the base layer coding portionand the enhancement layer coding portion In this manner, while performing fixed bit rate coding using a single transmission path, image quality of a moving image is made constant so as to prevent deterioration of image quality.

A control information decoding section () decodes sets of control information contained in a stream. Further, a random access information analyzing section () carries out analysis of locations of random access points of media items contained in the stream, on the basis of the sets of control information. Still further, a management information generating section () generates management information for managing a plurality of random access points contained in the stream, on the basis of decoded versions of the sets of control information, which has been obtained by the control information decoding section (), and the locations of the random access points obtained by the analysis performed by the random access information analyzing section (). Then, the management information thus generated and the stream are recorded onto a storage medium (). This makes it possible to quickly start playback in performing random-access playback of a stream into which control signals are inserted at regular intervals.

A mobile phone is electronics with 2D and 3D display function, having a first casing and a second casing linked to allow the phone to be foldable, and including a first display unit located inside with the phone folded, and selectively switching and displaying 2D and 3D images, and a second display unit located outside with the phone folded, and displaying a 2D image. When the mobile phone is opened or open the first display unit displays an idle screen in a 3D image as desired.
