摘要： In an image pick-up apparatus, the image on a visual field over an original copy is focused on an one-dimensional image pick-up device by a lens through a mirror. A prism for taking in the ambient light is disposed at the end portion of the one-dimensional image pick-up device. A sample-hold circuit samples and holds an ambient light signal portion of the image signal Vin and outputs a sample-hold signal Vref. A division circuit performs the operation of division Vin/Vref, using the sample-hold signal Vref. As a result, the image signal Vin will be normalized by the ambient light signal Vref for each scan line (line by line). An amplification circuit amplifies the output Vin/Vref of the division circuit so that the ambient light signal level may become VO and outputs it to an A/D conversion circuit. The image signal quantified by the A/D-conversion circuit is output to an external equipment by an external I/F circuit.

摘要： The present invention enables to scan in a sub scan direction an image on a scan medium placed on a flat plane using a simple configuration of a one-dimensional image sensor at a fixed position in combination with a reflecting mirror. A drive source having a constant rpm is used to rotate the reflecting mirror at an angular velocity changing in a non-linear way. The rotation of the drive source is transmitted to a drive mechanism linked to a four-node link mechanism to rotate the reflecting mirror at an angular velocity changing in a non-linear way, so that the scan position on the scan medium is shifted in the sub scan direction at a constant linear velocity.

摘要： Scanning is performed in a sub scan direction an image on a scan medium placed on a plane with a one-dimensional image sensor at a fixed position via a reflecting mirror rotatable around a fixed axis without causing a scan defect due to a change in the optical path length. An image light generating from an image on a scan medium is deflected by a reflecting mirror so at to form an image at a position of an image sensor via an image formation optical system. The image sensor reads a scan image as a one-dimensional main scan line and the reflecting mirror is rotated so at move a scan position in a sub scan direction. The rotation of this reflecting mirror is interlocked with displacement of the image formation optical system in an optical axis direction, thus enabling to prevent an image formation defect due to a change in the optical path length.

摘要： There is disclosed an image input method, comprising the steps of: forming an image of a linear area on an original onto a row of linearly arranged light receiving elements of a linear image sensor by a lens, and outputting an image signal of the linear image formed on the light receiving elements from the linear image sensor. Moreover, the linear area formed into the image on the linear image sensor is moved by a sub-scanning mechanism to scan the entire image of the original. The linear image sensor further outputs a flicker detection signal having a voltage corresponding to a lighting light quantity radiating to the original. Assuming that a photoelectric conversion property of the linear image sensor is linear, a correcting section eliminates a voltage fluctuation of the image signal based on a fluctuation of the lighting light quantity based on the flicker detection signal. In this case, a voltage for eliminating an influence by nonlinearity of the photoelectric conversion property of the linear image sensor is added to the image signal or the flicker detection signal inputted to the correcting section by an image signal correction circuit.
