Abstract: A vehicle number image pickup device includes an image pickup means for taking an image including identification information for identifying a vehicle in a predetermined frame period, an image division means for dividing each frame image obtained from the image pickup means into at least two images, a difference processing means for determining whether a different is present between frame images divided by the image division means, and an image output means for successively outputting the divided frame images for each frame when the different is determined to be present between the frame images by the difference processing means.

Abstract: A pair of cores is arranged so that their respective first end portions are opposed to each other across a given gap with a transfer path (M) for the passage of a medium between them. Coils wound individually on the respective first end portions of the cores are connected in series with each other to form a first coil. Coils 5a and 5b wound individually on second end portions of the cores are connected in series with each other to form a second coil. Coils wound individually on respective intermediate portions of the cores are connected in series with each other to form a third coil. A signal processing circuit is provided for AC-energizing the third coil to process a detection signal from the first coil and a detection signal from the second coil.

Abstract: A color detecting apparatus comprises a mechanism for decomposing light from an inspection target object into a plurality of kinds of wavelength components and for inputting the wavelength components as spectrum data, a memory for storing the spectrum data, a mechanism for calculating out a physical characteristic amount of the spectrum data, a memory for storing reference data to be used as reference for the characteristic amount, and a mechanism for comparing the characteristic amount with the reference data, thereby to determine whether or not a color of the inspection target object is a reference color.

Abstract: A predetermined position on a paper sheet is pointed by a finger, and a first image of the paper sheet picked up by an image pickup device before pointing by the finger is stored. A second image of the paper sheet picked up by the image pickup device upon pointing by the finger is stored. By subtracting the first image from the second image, the pointed position on the paper sheet by the finger is detected. The meaning or content data of a term at the detected position is read out from a database, and is displayed.
