Abstract: An encoding device includes: a frequency region converter which converts an inputted audio signal into a frequency region; a band selector which selects a quantization object band from a plurality of sub bands obtained by dividing the frequency region; and a shape quantizer which quantizes the shape of the frequency region parameter of the quantization object band. When a prediction encoding presence/absence determiner determines that the number of common sub bands between the quantization object band and the quantization object band selected in the past is not smaller than a predetermined value, a gain quantizer performs prediction encoding on the gain of the frequency region parameter of the quantization object band. When the number of common sub bands is smaller than the predetermined value, the gain quantizer non-predictively encodes the gain of the frequency region parameter of the quantization object band.
Abstract: A scanning endoscope apparatus, comprising a first transmitter, an actuator, a first optical filter, a second optical filter, a second transmitter, a first photo-detection unit, and a position determiner, is provided. The first transmitter transmits light to a first emission end. The actuator moves the first emission end. The first optical filter reflects the light of the first band. The second optical filter transmits the light of the first band at a transmittance that varies according to the position. The second transmitter transmits the light of the first band from a second incident end to a second emission end. The first photo-detection unit detects an amount of the light of the first band. The position determiner determines a position of the first emission end on the basis of the amount of the light of the first band.
Abstract: A scanning endoscope, comprising a first transmitter, an actuator, and a mirror, is provided. The first transmitter emits a beam of radiant light from an emission end. The actuator moves the emission end in a direction perpendicular to an emission direction. The mirror is arranged from the emission end in the emission direction when the emission end is on a predetermined standard point. The mirror comprises a reflection surface around a first straight line. The distance between a first position on the first straight line to any second position on the reflection surface increases as the first position is moved in the first direction. The reflection surface reflects the radiant light emitted from the first transmitter toward the observation area around the first straight line.

Abstract: A vector quantization apparatus performs coding of a linear predictive coding coefficient by multi-stage vector quantization. A first codebook and a second codebook store code vectors, and a storing section stores scalars. A first quantizing section extracts a first code vector stored in the first codebook and performs first stage quantization for quantizing a target vector using the first code vector. A second quantizing section extracts a second code vector stored in the second codebook, calculates a third code vector by multiplying the second code vector and one of the scalars stored in the storing section, performs distance calculation using the target vector, the first code vector and the third code vector, and performs second stage quantization for quantizing the target vector using a result of the distance calculation. Each scalar stored in the storing section is associated with at least one of the vectors stored in the first codebook.

To overlay a rendered image with a stereoscopic video image to be displayed in the i-th frame period, a process of writing to a left-view plan memory and a process of writing to a right-view plane memory both need to be completed before the start of the i-th frame period. To simultaneously request the two rendering processes, the argument of an application interface includes a pair of specifications, one specifying writing to the left-view plane memory and the other specifying writing to the right-view plane memory.
Abstract: A discharge lamp lighting device includes: a power converting circuit including a step-down chopper circuit and a polarity inversion circuit configured to convert an output from the step-down chopper circuit to a rectangular-wave alternating-current voltage, and thus to apply the rectangular-wave alternating-current voltage to a discharge lamp; and a memory configured to store a history of an output from the power converting circuit in a previous stable lighting mode. A control circuit controls on and off of each of switching elements in the step-down chopper circuit and the polarity inversion circuit, and thereby changes the output from the power converting circuit in a predetermined time period after the lamp starts lighting until reaching a stable lighting state on the basis of the history stored in the memory, so that a rise of a lamp voltage is suppressed. This enables extension of the lifespan of the lamp and suppression of the occurrence of arc jump.
