摘要： A stationary data symbol reader includes a CCD, lens, CCD drive circuit, amplification circuit, binarization circuit, memory, CPU, light sources, light source drive circuit, communication driver, switch circuit and trigger switch. When reading, a frame image capture is carried out, and a number of picture elements of the fields of the frame corresponding to the displacement of an authenticator pattern (associated with the data symbol) between a second field image and a first field image is calculated. The moving speed of the data symbol is calculated from the displacement. The optimal light exposure time is calculated from the moving speed, and the optimal intensity of illumination is calculated from the exposure time.

摘要： A data symbol reading device has a casing which includes a hand grip and a head part. The casing includes signal processing circuits, a light source, an image sensing device, and an optical system. The optical system directs light reflected from a symbol reading area such that an image is formed on a light receiving surface of the image sensing device. An indication unit, comprised of five LEDs, is provided on an easily visible surface of the casing. If, in the reading process, it is determined that a data symbol is fully within the symbol reading area, a central LED is illuminated. However, if the data symbol is protruding outside the symbol reading area, one or more LEDs are illuminated to indicate the direction of protrusion.

摘要： A video scope has an image sensor, a circuit board, and a digital signal processor mounted on the circuit board. The digital signal processor reads image signals from the image sensor, and processes the read image signals to thereby produce at least two types of video signal. A wiring-pattern is formed on the circuit board to feed a video signal component, included in one of the two types of video signals, from the digital signal processor. The wiring-pattern is cut off at a suitable location. When the wiring-pattern remains as an unused wiring-pattern on the circuit board, the wiring-pattern is treated such that radiation of noise is prevented from going through the unused wiring-pattern.
