Abstract: An image processing apparatus processes image data two-dimensionally arrayed in vertical and horizontal directions. A vertical size changing section changes a size of the image data in the vertical direction. A horizontal size changing section changes the size of the image data changed by the vertical size changing section in the horizontal direction. A display section displays the image data changed in size in the vertical and horizontal directions.

Abstract: A three-dimensional image evaluation unit (100) for evaluating an input image. The parallax statistic is calculated by measuring the parallax included in the input image by a parallax measuring means (3), the static parallax evaluation value for the calculated parallax statistic and/or a dynamic parallax evaluation value for a temporal change in the parallax statistic is determined by a static parallax evaluating means (4-1) and/or a dynamic parallax evaluating means (4-2) of an evaluating means (4) to evaluate parallax information on the image. An abrupt change in the parallax can be evaluated thereby, and countermeasures against errors in measurement and noise of the image can be taken, so that parallax information on the image can be suitably evaluated.

Abstract: Disclosed is a personal watercraft comprising an engine capable of achieving a high power without increasing the diameter of an output shaft where a crankshaft-side sprocket is attached, and thus without increasing the diameter of the sprocket. The engine is configured such that an extended shaft that is separable from the crankshaft and has a diameter smaller than that of the crankshaft is connected to one end portion of the crankshaft so as to be coaxial with the crankshaft, and a sprocket is provided on the extended shaft. With such a structure, by forming the extended shaft of a material having relatively high strength, the diameter of the extended shaft can be made smaller than that of the crankshaft, and hence, the diameter of the sprocket provided on the extended shaft can be reduced. Since the diameter of a camshaft-side sprocket can be reduced, the size of the entire engine can be reduced.
