  • Publication number: 20190304479
    Abstract: The present technology relates to an encoding apparatus, an encoding method, a decoding apparatus, a decoding method, and a program for obtaining sound of higher quality. An audio signal decoding section decodes encoded audio data to acquire an audio signal of each object. A metadata decoding section decodes encoded metadata to acquire a plurality of metadata about each object in each frame of the audio signal. A gain calculating section calculates VBAP gains of each object in the audio signal for each speaker based on the metadata. An audio signal generating section generates an audio signal to be fed to each speaker by having the audio signal of each object multiplied by the corresponding VBAP gain and by adding up the multiplied audio signals. The present technology may be applied to decoding apparatuses.

  • Publication number: 20190306648
    Abstract: The present technology relates to a sound processing apparatus and a sound processing system for enabling more stable localization of a sound image. A virtual speaker is assumed to exist on the lower side among the sides of a tetragon having its corners formed with four speakers surrounding a target sound image position on a spherical plane. Three-dimensional VBAP is performed with respect to the virtual speaker and the two speakers located at the upper right and the upper left, to calculate gains of the two speakers at the upper right and the upper left and the virtual speaker, the gains being to be used for fixing a sound image at the target sound image position. Further, two-dimensional VBAP is performed with respect to the lower right and lower left speakers, to calculate gains of the lower right and lower left speakers, the gains being to be used for fixing a sound image at the position of the virtual speaker.

  • Publication number: 20190297200
    Abstract: An image forming apparatus includes a sensor, an operation section, and a controller. The sensor detects a sensor target. The operation section receives an operation instruction. The controller executes a setting process for controlling the sensor. The setting process is a process to adjust a sensitivity of the sensor according to detection precision. The detection precision is a relationship in a first unit period between the number of times the sensor detects the sensor target and the number of times of the operation section receives the operation instruction.

  • Publication number: 20190289155
    Abstract: A controller of an information processing device changes a current state among standby states including a first standby state, a second standby state, and a third standby state, in which power consumption decreases in this order. When the non-operation duration runs for a first period, the controller changes the current state from the first standby state to the second standby state. When the non-operation duration subsequently runs for a second period, the controller changes the current state from the second standby state to the third standby state. When the sensor detects a detection target in the second standby state or the third standby state, the controller changes the current state to the first standby state. When the non-operation duration runs for a third period starting from state change, the controller changes the current state from the first standby state to the previous standby state.

  • Patent number: 10324523
    Abstract: An image following a movement of a head of a user who observes an image is generated. At a drawing device 300, posture angle data to be received at a certain time after a time series of posture angle data that have already been received are predicted, and rendering processing is performed on an image based on the predicted posture angle data. A prediction algorithm for the posture angle data is roughly divided into two steps: (1) estimating a predicted time to receive the posture angle data; and (2) predicting the posture angle data at the predicted time. By rendering the image at the predicted time from the predicted posture angle data, a sense of delay felt when the image following the movement of the head of the user is presented is reduced.

    Abstract: The present invention relates to a signal processing apparatus and a signal processing method, an encoder and an encoding method, a decoder and a decoding method, and a program capable of reproducing music signal having a better sound quality by expansion of frequency band. An encoder sets an interval including 16 frames as interval section to be processed, outputs high band encoded data for obtaining the high band component of an input signal and low band encoded data obtained by encoding the low band signal of the input signal for each section to be processed. In this case, for each frame, a coefficient used in estimation of the high band component is selected and the section to be processed is divided into continuous frame segments including continuous frames from which the coefficient with the same section to be processed is selected.
