摘要： An optical system for image projection is disclosed which is easy to be manufactured and designed and capable of projecting a bright image with high contrast. The optical system includes an illumination optical system introducing a luminous flux emitted from a light source to an image-forming element through an optical surface having a light-splitting function, and a projection optical system projecting the luminous flux from the image-forming element through the optical surface onto a projection surface. The illumination optical system includes a conversion system which respectively converts the widths of the luminous flux in first and second cross-sections into widths different from those before entering thereinto. Conversion rates in the first and second cross-sections are different from each other.

摘要： According to one embodiment, a signal processor includes a band divider, a first correction module, a determiner, an adjuster, and a second correction module. The band divider calculates an amplitude indicating sound pressure from an acoustic signal for each frequency range. The first correction module corrects the amplitude to change the dynamic range of the amplitude to a target range. The determiner determines whether the maximum amplitude of amplitudes corrected by the first correction module is equal to or larger than a threshold. The adjuster adjusts first and second coefficients based on the first condition if the maximum amplitude is equal to or larger than the threshold. The second correction module adds a value obtained by multiplying the acoustic signal by the first coefficient to a value obtained by multiplying the correction amount of the amplitude by the second coefficient, and outputs a resulting value as an output signal.

摘要： An echo cancelling device splits a low-band signal through LPFs having characteristics which do not cause aliasing during downsampling of downsamplers, and splits a high-band signal through HPFs having characteristics which do not cause aliasing during downsampling of downsamplers. The echo canceling device generates a mid-band signal by subtracting the low-band signal and the high-band signal from a pre-split signal by adder-subtractors, and cancels an echo on a band-by-band basis.
