Abstract: A first mirror and a second mirror are disposed in such a manner that their reflective surfaces are parallel and face toward each other. A mark is drawn between the first mirror and the second mirror. An image of the reflections of the mark in the first mirror and the second mirror is captured with a camera. Calibration of the camera system is performed based on the image.

Abstract: An image input unit inputs a plurality of images in a time series. Each input image includes a boundary line extending toward a vanishing point on a plane. A reverse projection image generation unit generates a reverse projection image of each input image by projecting information related to each input image onto the plane. A boundary line detection unit detects the boundary line from the reverse projection image by identifying a boundary line candidate on each reverse projection image.

Abstract: A microcomputer comprises: a first electric power source VDD1 to which a condenser 30 used for backup is added; a second electric power source VDD2 to which the condenser 30 used for backup is not added; and a resistance load 40 added to the second electric power source. When a supply of voltage of the second electric power source VDD2 is stopped, a level of the second electric power source VDD2 is changed from a high level to a low level, and when the supply of voltage of the second electric power source VDD2 is resumed, the level of the second electric power source VDD2 is returned from the low level to the high level.

Abstract: Provided are a first RC oscillator (10) including a resistance and capacitor, a counter (20) for counting the number of source oscillation clocks from the first RC oscillator (10), a frequency setting register (30) for setting the number of source oscillation clocks in accordance with a desired oscillation frequency, and a comparator for comparing between a count value of the counter (20) and a set value of the frequency setting register (30). A clock is outputted depending upon a result of comparison by the comparator.

Abstract: A program for rewriting data in an address region B is written in an address region A which can be rewritten by an external PROM writer. After resetting the microcomputer and rewriting the program in address region A, the reset state is cancelled and the last address in address region A of the EEPROM (1) is then stored in a register (17). An address detector (18) prohibits rewriting in address region A based on an address value stored in the register (17).

Abstract: In a dynamic image processing apparatus of the present invention, the focus of contraction of the optical flow of the background in the dynamic image is extracted. When a series of dynamic images are inputted, an optical flow extraction section extracts an optical flow representing motion vector of each block between two neighboring dynamic images. A Hough transform section votes each optical flow of the dynamic image to vote space by unit of block. The vote space comprises two planes and one circle positioned in parallel to each other. The dynamic image is included in one plane. The other plane is positioned symmetrically to the one plane with respect to a center position of the circle. The Hough transform section selects a block whose voted value is maximum in all blocks of the vote space. The selected block corresponds to the focus of contraction of the optical flow of background in the dynamic image.

A multiplicity of contact pins each extend discretely in and through the guide grooves for connection with the printed circuit board. The substrate has a cavity dimensioned to receive an integrated circuit for connection between the multi-pin terminal adapter and a relay socket which is releasably connected to the substrate.
