    摘要： The present disclosure relates to an image processing device and method that enable improvement in processing efficiency in encoding or decoding.
    A type E0 of an LCU 115 and its coefficient are determined on the encoder side. The coefficient of the type E0 was sent to the decoder side at the time of the LCU 111, and has been stored in an EO buffer included in an adaptive offset filter on the decoder side. For the LCU 115, therefore, a copy of the coefficient of the type E0 in the EO buffer is used on decoder side without the sending of the coefficient of the type E0. As described above, the parameters of the adaptive offset filter, which are transmitted in one batch at the beginning of a frame in the related art, are sent sequentially at the beginning of an LCU for each LCU. The present disclosure can be applied to, for example, an image processing device.

    摘要： The present technique relates to an image processing apparatus and an image processing method capable of generating a color image of a display viewpoint using a color image and a depth image of a predetermined viewpoint.
    The viewpoint generation information generation unit generates viewpoint generation information used to generate a color image of a display viewpoint in accordance with a generation method of the color image of the display viewpoint obtained by performing warping processing using multi-viewpoint corrected color images and multi-viewpoint depth images. The multi-viewpoint image encoding unit encodes the multi-viewpoint corrected color images and the multi-viewpoint depth images, and transmits them with the viewpoint generation information. The present technique can be applied to, for example, a multi-viewpoint image processing apparatus.

    摘要： 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.

    摘要： The present disclosure relates to an image processing apparatus and method that can keep reduction in coding efficiency to a minimum.
    A scaling list is set that has values appropriate to a current block size for the current block to be quantized in an image to be coded, quantization is performed using the set scaling list, and coded data is generated by coding an acquired quantization coefficient. The present disclosure is applicable, for example, to an image processing apparatus, an image coding apparatus, an image decoding apparatus, and so on.
