  • Publication number: 20120294461
    Abstract: Sound equipment is configured to average an average value of a signal level at each predetermined frequency band of a sound signal at a different averaging time, to weight the average value calculated at a different averaging time by using an individual weighting value, to obtain a representative value based on a weighted average value, to determine a gain of a sound signal based on an obtained representative value, to correct a volume based on the corresponding gain, and to correct a volume based on the gain. The representative value is obtained by selecting the average value at which a gain becomes minimum within each weighted average value. The averaging performs at least a first averaging using the averaging time corresponding to the sound signal that the signal level changes rapidly, and a second averaging using the averaging time longer than the averaging time of the first averaging.

  • Publication number: 20120288121
    Abstract: A DSP performs a sound volume adjustment processing that adjusts a playback sound volume in accordance with a signal level of acoustic data in acoustic contents. Further, when the DSP detects that the acoustic data is switched, the DSP initializes the adjustment to perform a reset processing that performs adjustment in accordance with the acoustic data which is a new playback target. When the changing instruction of the playback position of the acoustic data is accepted, an audio microcomputer instructs the DSP to perform the reset processing.

  • Publication number: 20120229819
    Abstract: An image processing apparatus includes a setting unit and a correcting unit. The setting unit sets a gloss level of an image to be formed by forming plural toner images using a transparent toner and plural color toners having different colors and by fixing the plural toner images onto a recording medium in such a manner that the plural toner images are placed on top of one another on the recording medium. The correcting unit corrects image data defining density values per pixel of the toner images formed using the plural color toners of the respective colors so that a total density value that is a sum of a density value per pixel of the toner image formed using the transparent toner and density values per pixel of the toner images formed using the plural color toners of the respective colors may not exceed a predetermined threshold.

  • Publication number: 20120229820
    Abstract: An image processing apparatus includes a setting unit, a generating unit, and a converting unit. The setting unit sets a gloss level of each of plural areas into which an image is divided. The image is formed by forming plural toner images having different colors using plural first toners and at least one second toner having at least one same color as the first toners and by fixing the plural toner images onto a recording medium so as to be superimposed on one another. The generating unit generates multi-level image data for each of the first toners and the at least one second toner in accordance with the gloss levels set by the setting unit. The converting unit converts multi-level image data of toners having the same color into binary image data. The converting unit also converts multi-level image data of toners having different colors into binary image data.

  • Publication number: 20120100421
    Abstract: Disclosed is a battery 10 including: an electrode group including a positive electrode, a negative electrode, and a separator; an electrolyte; and a battery container accommodating the electrode group and the electrolyte. The battery container includes an accommodating portion 16 having an opening, and a lid sealing the opening of the accommodating portion 16. The battery container includes a liquid-retaining portion 16a retaining the electrolyte therein below the liquid surface of the electrolyte, and a gas-retaining portion 16b retaining gas therein above the liquid surface of the electrolyte. The liquid-retaining portion 16a of the side portion of the battery container is thinner than the gas-retaining portion 16b of the battery container. This suppresses scattering of fragments etc. in the event of rupture of a secondary battery due to an increase in the internal pressure. The safety of the secondary battery is thus increased.
