Abstract: A method and apparatus for detecting roller eccentricity in a CIS scanner is disclosed. An image of a target is captured using the CIS scanner. The image of the target is analyzed for periodic horizontal banding. The period of the periodic horizontal banding is compared with the circumference of a pressure roller in the CIS scanner. When the period matches with the circumference of the pressure roller, an error is set.

Abstract: An image reading apparatus which is capable of performing a stable reading operation and matching a sub-scanning magnification with which an original image is scanned, between the front side of an original and the reverse side of the same. A CCD line sensor reads the front side of an original, and a CIS line sensor reads the reverse side of the same. A lead roller is disposed upstream of the CCD line sensor and conveys the original at a first conveying speed. A discharge roller is disposed downstream of the CCD line sensor and conveys the original at a second conveying speed which is higher than the first conveying speed. A CPU controls one main scanning time period of the CCD line sensor after the original is held by the discharge roller, such that the one main scanning time period becomes shorter than before the original is held by the discharge roller.

Abstract: An imaging lens good in mass-productivity, compact, low in manufacturing cost, good in aberration performance is provided by effectively correcting aberrations without greatly varying the variation of the thickness of a curing resin. An imaging device having such an imaging lens and a portable terminal are also provided. A third lens (L3) has a flat surface on the object side, a convex surface near the optical axis on the image side, and a concave aspheric surface around the peripheral portion within the region where a light beam passes. Therefore, it is possible to reduce the other optical aberrations such as distortion and simultaneously to design the imaging lens so that the astigmatism takes on a maximum value at the outermost portion. Hence, the resolutions at low to middle image heights are high. In addition, such a shape does not cause a large variation of the thickness of the third lens (L3) from the region along the axis to the periphery. Therefore, the thickness of the third lens (L3) can be small, and the material cost can be reduced.
