摘要:
An image coding apparatus that makes possible the parallelization of intra prediction, and outputs coded data that can be decoded by an image decoding apparatus compliant with the H.264 standard. The image coding apparatus performs orthogonal transformation, quantization, inverse quantization, inverse orthogonal transformation, and intra prediction on all blocks obtained when a single macroblock is divided into plural blocks, and includes: a predicted block control unit that causes all of the blocks to be intra predicted using at least one of the intra prediction modes specified in the H.264 standard on at least some of the blocks, in an order different from the raster scan order specified in the H.264 standard; and an sorting buffer that outputs, in the raster scan order, all the blocks intra predicted under the control of the predicted block control unit.

The instant application describes a display device for switching a display mode between a first display mode for displaying a stereoscopic image with an eyewear device, and a second display mode, which is different from the first display mode. The display device includes a signal generator, which generates a timing signal for notifying a timing of an increasing period of an incident light amount to left and right eyes or a stop signal for stopping the adjustment operation as a control signal, which is transmitted by a transmitter to the eyewear device. The transmitter transmits the timing signal for the first display mode while the image is displayed in the first display mode. If the display mode is then switched from the first to second display mode, the transmitter sequentially transmits the stop signal and the timing signal for the second display mode to the eyewear device.

The instant application describes display device for switching display mode between first display mode for displaying stereoscopic images with eyewear device which adjusts incident light amounts to the left and right eyes, and second display mode different from the first display mode. The display device includes signal generator which generates timing signals for notifying timings of increasing the incident light amount to the left and right eyes in the first and second display modes or stop signals for stopping the adjustment operation, as control signals for the adjustment operation; and transmitter which transmits the control signals to the eyewear device. During the first display mode, the transmitter transmits the timing signals for the first display mode. Switching operation from the first to second display mode causes the transmitter to transmit the stop signal and then the timing signal for the second display mode to the eyewear device.
