    Abstract: The present technology relates to an encoding device and an encoding method, and a decoding device and a decoding method configured to reduce an encoding amount of the encoded stream when information regarding a depth image is included in the encoded stream.A DPS encoding unit sets depth image information, which is information regarding a depth image, as a DPS different from a sequence parameter set and a picture parameter set. A slice encoding unit encodes the depth image to generate encoded data. Further, the slice encoding unit transmits an encoded stream including the DPS and the encoded data. The present technology can be applied to, for example, a multi-view image encoding device.

    Abstract: A reference direction determination unit 44 detects, using an input image, a scene change, a flash scene, or a monotonous luminance variation section. In a case where an encoding target image is the scene change or flash scene, the reference direction determination unit 44 determines its mode as a fixed reference direction mode in which a reference direction in a screen is fixed uniformly. Further, in a case where the encoding target image is the monotonous luminance variation section, that is, a section where luminance of an entire screen monotonously increases or monotonously decreases, the reference direction determination unit 44 determines as the fixed reference direction mode in which the reference direction in the screen is fixed uniformly. A motion prediction/compensation unit 42 performs inter prediction processing according to a determination result of the reference direction determination unit 44, thereby enabling efficient encoding while suppressing deterioration of image quality.

    Abstract: The present technology relates to a decoding device and a decoding method, and an encoding device and an encoding method that enable images that configure a packed image to be reliably displayed when an encoded stream is decoded and displayed. A decoding unit decodes an encoded data, the encoded data being an encoded packed image in which a plurality of images is packed, and generates the packed image. A display control unit identifies the images that configure the packed image based on packing SEI preferentially used when the packed image is displayed. The present technology can be applied to a decoding device, for example.

    Abstract: The present technology relates to an image processing device and an image processing method that are capable of improving the encoding efficiency of a parallax image by using information relating to the parallax image. A correction unit sets a calculation precision of a calculation that is used when performing a depth weighting prediction process that uses a depth weighting coefficient and a depth offset with the depth image as a target. A correction unit performs the depth weighting prediction process in relation to the depth image according to the calculation precision that is set, and generates a depth prediction image. A calculation unit generates a depth stream by encoding the depth image using the depth prediction image. The present technology can be applied to an encoding device of the parallax image, for example.

    Abstract: The present disclosure relates to an encoding device and an encoding method capable of reducing a storage capacity necessary for bidirectional prediction. An accuracy transform unit transforms a motion vector with fractional pixel accuracy of an input image into a motion vector with integer pixel accuracy of the image for each of prediction directions for bidirectional prediction of the input image. An average unit forms a predicted image of the input image for bidirectional prediction on the basis of the motion vector with integer pixel accuracy transformed by the accuracy transform unit for each prediction direction. The present disclosure is applicable to an encoding device of high efficiency video coding (HEVC) system, for example.
