| 20110004476 | Apparatus and Method for Creating Singing Synthesizing Database, and Pitch Curve Generation Apparatus and Method - Variation over time in fundamental frequency in singing voices is separated into a melody-dependent component and a phoneme-dependent component, modeled for each of the components and stored into a singing synthesizing database. In execution of singing synthesis, a pitch curve indicative of variation over time in fundamental frequency of the melody is synthesized in accordance with an arrangement of notes represented by a singing synthesizing score and the melody-dependent component, and the pitch curve is corrected, for each of pitch curve sections corresponding to phonemes constituting lyrics, using a phoneme-dependent component model corresponding to the phoneme. Such arrangements can accurately model a singing expression, unique to a singing person and appearing in a melody singing style of the person, while taking into account phoneme-dependent pitch variation, and thereby permits synthesis of singing voices that sound more natural. | 01-06-2011 |
| 20110002553 | COMPRESSIVE CODING DEVICE AND DECODING DEVICE - A compressive coding device is constituted of a coordinates conversion process converting original pixel data of the RGB presentation into pixel data of the YCbCr presentation, an irreversible conversion process, and a reversible compressive coding process. In the irreversible conversion process, the components Cb and Cr of pixel data are thinned out by way of a reduction process and subsequently interpolated based on the component Y of pixel data by way of an expansion process, while some bits of pixel data are reduced by way of a quantization process. The reversible compressive coding process performs a predictive coding process and a variable-length coding process on each pixel data selected in a raster-scanning sequence, thus producing compressive coded data. This makes it possible to decode both reversible compressive coded data and irreversible compressive coded data in units of lines. | 01-06-2011 |
| 20110002551 | COMPRESSIVE CODING DEVICE AND VISUAL DISPLAY CONTROL DEVICE - A compressive coding device converts three color components of pixel data from the RGB presentation to the YCbCr presentation according to a mapping rule. Converted pixel data are subsequently subjected to irreversible compressive coding, thus producing compressive coded data. Pixel data ascribed to transparency control are converted to a prescribed value out of a mapping range according to the mapping rule. Compressive coded data are supplied to a visual display control device, in which they are decoded and reproduced into original pixel data of the first color presentation. Compressive coded data corresponding to pixel data ascribed to transparency control are rendered with a prescribed color in the RGB presentation which is designated as transparency in advance or not rendered on screen. Thus, it is possible to precisely perform the transparency control without causing a reduction of the compression factor regardless of the irreversible compressive coding and decoding. | 01-06-2011 |

| 20100326402 | Accelerator Opening Degree Estimation and Engine Sound Generation - During travel of a vehicle, an apparatus acquires vehicle velocity information detected by a vehicle velocity sensor and a reference accelerator opening degree and an estimated gear position from a reference accelerator opening degree table indicative of relationship between vehicle velocities and accelerator opening degrees during travel of the vehicle at cruising velocity. The apparatus also acquires an estimated number of prime mover rotations at the vehicle velocity from a vehicle-velocity vs. number-of-prime-mover-rotation correlation table, and then calculates a difference between the estimated number of prime mover rotations and an actual number of prime mover rotations detected by a number-of-prime-mover-rotation sensor. Further, a value, obtained by multiplying the calculated difference by a compensating coefficient determined in accordance with characteristics specific to the vehicle, is added to the reference accelerator opening degree, to thereby calculate an estimated accelerator opening degree. | 12-30-2010 |

| 20100326257 | KEYBOARD APPARATUS - In a keyboard apparatus including a key supported for pivoting movement about a pivot point, a mass member that imparts a reaction force to performance operation of the key in interlocked relation to the key, and an electromagnetic actuator provided between the key and the mass member for imparting a driving force to the key and mass member, a transmission member is provided in detachable abutment with the key and mass member. The transmission member can be disengaged from the key or the mass member depending on operating conditions of the key and the mass member. Thus, it is possible to not only prevent unnecessary binding forces from acting in areas where the transmission member and the key and the mass member abut against each other, but also achieve smooth movement of the key and the mass member and prevent increase of inertial mass of the transmission member. The smooth movement of the key and mass member can achieve force sense control with good responsiveness. Further, the key is pivotable in a key depressing direction as a reaction force imparted from the mass member is reduced by impartment, to the key, of a driving force by the actuator. Thus, the apparatus can perform both force sense control on depression operation of the key and an automatic performance involving automatic operation of the key, through cooperation between a reaction force imparted from the mass member to the key and the driving force imparted from the actuator to the key. | 12-30-2010 |
