First Claim
Patent Images

1. image-input device comprises:

  • Light irradiation device light shines object;

    Sensor detects the light from this object, and has disposed a plurality of pixels;

    Driving circuit, drive the sensor, so that the zero hour and the finish time between the exposure period of the 1st pixel area in a plurality of pixels of this sensor, and differ from one another the zero hour and the finish time between the exposure period of the 2nd pixel area that spatially is different from above-mentioned the 1st pixel area in above-mentioned a plurality of pixel;

    AndController was controlled between the light period of above-mentioned light irradiation device, made the rayed condition changing of above-mentioned the 1st pixel area and above-mentioned the 2nd pixel area,Wherein, the sensor, along continuous straight runs and vertical direction configuration pixel;

    Above-mentioned driving circuit, each row that comprises a plurality of pixels of horizontal scan direction successively;

    Above-mentioned controller, control above-mentioned light irradiation device, make scan-synchronized ground irradiates light with each row, and make during the lighting of the light of being longer than each row when the neighboring area of the sensor is scanned during the lighting of light of each row when the middle section to the sensor scans.
