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.

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: There is provided an image processing device and method capable of suppressing a decrease in subjective image quality. A size of a current block for a prediction process is set according to a size of a peripheral block situated on a periphery of the current block. The prediction process is to generate a predicted image of an image to be encoded. An intra prediction process is performed on the current block that has been set and the predicted image is generated. The image to be encoded is encoded using the predicted image that has been generated. The present disclosure can be applied to, for example, an image processing device, an image encoding device, or an image decoding device.
