    摘要: A linear image sensor device with at least two lines including linear sensors 10, 20, which device is capable of showing a wide dynamic range. In the linear image sensor device, one linear sensor 10 is made to have a high sensitivity, while the other linear sensor 20 is made to have a low sensitivity. The linear sensors are respectively equipped with readout gates 13, 23 for reading out charges from sensor arrays 12, 22 comprising a number of pixels and CCD analog shift registers 14, 24 for transferring the charges read out. In the other linear sensor 20, analog memories 29a, 29b are provided between the readout gate 23 and the CCD analog shift register 24. Owing to the provision of the analog memories 29a, 29b, the signal outputs OUT1, OUT2 simultaneously occur, which can eliminate a problem coming from the difference in position between the lines.

    摘要: The present invention is directed to a light source switching type color image scanner in which a color signal can be read out at high speed by reducing a read-out time. A red light source (3), a green light source (4) and a blue light source (5) which can be selectively switched are disposed under an original document holder (1) on which an original document (2) is held. Further, there are disposed a mirror (7) and a lens (8) which are used to focus a reflected image of the original document (2) onto a CCD linear image sensor (6). The CCD linear image sensor (6) includes a shutter gate (12) and a shutter drain (13) which are used to reset signal charges of remaining lights from the respective light sources (3), (4) and (5). The reset of a signal charge begins before a next color light source is energized.
