Title: Fingerprint image input device
Inventor: MORISHITA JO
IPC: G06K9/20
Filed: 1985-11-21
Abstract: PURPOSE:To attain the miniaturization and the cost reduction of a device by providing an illumination means which illuminates uniformly, and a control means which controls a switching between the timing of the conversion of a D/A conversion means, the read/write timing of an image accumulation means, and the selection signal of a video signal selection means. CONSTITUTION:A television camera 4 image-picks up a fingerprint on a sheet of fingerprint input paper 2, and inputs a video signal to an A/D converter 5 and a video selection circuit 8. A storage circuit 6 accumulates a quantized fingerprint image outputted from the A/D converter 5 according to the write timing and an address from a control circuit 10, and outputs the quantized fingerprint image to confirm the input quality of an accumulated image according to the read timing from the control circuit 10, then inputting to a D/A converter 7. A video signal selection circuit 8 selects and outputs the video signal in the inputting time of the fingerprint image, and in the confirming time of an input image, it is controlled with the control circuit 10 so as to select and output the video signal from the D/A converter 7. Thus, by using the television camera in stead of a one-dimensional image sensor, a mechanical carrying mechanism is made unnecessary, and the device can be miniaturized and its cost is reduced.

Filed: 1999-09-20
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus for supporting a notice board which can save a space when the board is rotated vertically or horizontally, and an electronic black board using the apparatus.
