    Abstract: A nanoparticle measurement device (9) includes a timing signal generation unit (92), a low-frequency component extraction unit 95), a low-frequency component calculation unit (96), a threshold correction unit 96), and a measurement unit (94). The timing signal generation unit generates timing signals. The low-frequency component extraction unit extracts low-frequency components according to the timing signals. The low-frequency component calculation unit calculates an interpolated low-frequency component in accordance with the low-frequency components. The threshold correction unit sets a corrected threshold in accordance with the interpolated low-frequency component. The measurement unit extracts and counts nanoparticle pulse signals from a light reception signal according to the timing signals and the corrected threshold.

    Abstract: A virtual image display device 10 includes: a display unit 14 that generates an image display light L by modulating an illumination light; and a projection optical system 16 that includes at least a concave mirror 18 for reflecting the image display light L toward a virtual image presentation plate 22. The display unit 14 is provided at a position nearer a focal point 26m within a meridional plane of a composite optical system 20 formed by the virtual image presentation plate 22 and the projection optical system 16 than a focal point 26s within a sagittal plane of the composite optical system 20.

    Abstract: A filter generation device according to this embodiment is configured to generate a filter for performing an out-of-head localization process on a high resolution digital audio signal, the filter generation device including: microphones (2L, 2R); and a filter generation unit (351) configured to generate a filter corresponding to a transfer characteristic from left and right speakers (5L, 5R) to the left and right microphones (2L, 2R). A predetermined frequency lower than a Nyquist frequency of a sound pickup signal is assumed as a first frequency (24 kHz). The filter generation unit (351) sets an amplitude component in a low frequency band (BH) of the filter corresponding to a frequency amplitude characteristic of the sound pickup signal, and the filter generation unit (351) generates an amplitude component in a high frequency band (BH) of the filter such that the amplitude component in the high frequency band (BH) is allowed to be connected to the amplitude component in the low frequency band BL.

    Abstract: In a picture coding device that partitions differential information between a picture that is a coding target and a picture that is a prediction target into a plurality of sub blocks and codes the partitioned sub blocks in a predetermined sequence, a significant sub block information coding controller (708) and a calculation encoder (701) code significant sub block information that represents whether or not all the values of differential coefficients belonging to the sub block are zero. A significant coefficient information coding controller (706) and the calculation encoder (701) code significant differential coefficient information that represents whether or not the value of the differential coefficient is zero. A differential coefficient value coding controller (707) and the calculation encoder (701) code the value of the differential coefficient.
