摘要： A separation signal generation unit generates a plurality of separation signals which are independent from one another from the mixed signals for one frame which are converted into those in a frequency region. A mask processing unit judges a noise condition of a first separation signal for each frequency bin on the basis of the first separation signal and second separation signals. The mask processing unit further removes a first noise component obtained on the basis of a judgment result on the noise condition from the first separation signal. A noise amount measuring unit measures the amount of noise in the first separation signal. A noise signal selection unit selects a noise signal for each frequency bin on the basis of the amount of noise measured by the noise amount measuring unit. A noise removing unit removes a second noise component from a noise removal signal inputted from the mask processing unit. The noise removing unit outputs the noise removal signal obtained by removing the second noise component as a target signal.

摘要： An optical apparatus includes an optical unit including a light entrance surface, light reflecting surfaces and a light exit surface all of which are integrally formed of transparent material, and the optical unit has in its interior an internal refracting surface for refracting light. Since a light beam passes through the optical unit from the light entrance surface to the light exit surface via the internal refracting surface and the light reflecting surfaces along a bent optical path, the optical apparatus is reduced in size and improved in optical performance, particularly, well corrected in chromatic aberration. Another disclosed optical apparatus is arranged to achieve zooming by using a plurality of optical units each of which is similar to the aforesaid optical unit.
