Abstract: A size measurement apparatus includes: a first light emitter unit for widely emitting light to an imaging area which may include an object; a second light emitter unit for locally emitting light to a part of the imaging area; an image taking unit for obtaining a range image which contains distance information on a pixel-by-pixel basis, with pixels being arranged two-dimensionally, the distance information being calculated based on a measured time value which is a time for the light emitted from the light emitter units to travel back as a reflected light; and an arithmetic control unit for controlling light emission from the light emitter units, and for calculating size information of the object based on a synthesized range image obtained by synthesizing a range image obtained during light emission from the first light emitter unit and a range image obtained during light emission from the second light emitter unit.

Abstract: An edge emphasizing circuit includes a weighing addition circuit, and the weighing addition circuit performs on the basis of a weighing coefficient applied from a coefficient calculating circuit a weighing addition with respect to raw image data and data obtained by performing a filtering process on the raw image data by a median filter. Then, an aperture signal producing circuit produces an aperture signal on the basis of a result of the weighing addition. The aperture signal is in an adder superimposed on Y data output from a signal processing circuit, whereby an edge component of the Y data is emphasized.

Abstract: An image signal processing apparatus includes a line separation circuit. When interpolated image data is generated based on low resolution raw image data having color information distributed on a pixel of each line in the order of R, G, G, B, . . . , firstly, the line separation circuit converts a color distributing manner using two line memories. As a result of a conversion, the color information is distributed on the pixel of an odd number line in the order of R, G, R, G, . . . , and the color information is distributed on the pixel of an even number line in the order of G, B, G, B, . . . . Such a color separation toward the low resolution raw image data is performed using three line memories. On the other hand, when the interpolated image data is generated based on high resolution raw image data having the color information distributed on the pixel of the odd number line in the order of R, G, R, G, . . .
