摘要： After light transmitted through platen glass is incident on a lens and focused, the light is transmitted through a parallel flat plate and imaged in a CCD image sensor. The resolving power of the CCD image sensor is 600 dpi in this case and one pixel is 8 &mgr;m. A parallel flat plate is provided with a function for displacing all rays incident on the plate in parallel. The quantity of parallel displacement differs depending upon each wavelength. Therefore, lateral chromatic aberration can be reduced to the extent that it is ignorable (approximately {fraction (1/10)} of pixel size) by making reflected light outgoing from the lens and having lateral chromatic aberration incident on the parallel flat plate.

摘要： Light reflected from a document surface is given first color dispersion when passing through a prism interface and second color dispersion when passing through another prism interface. The second color dispersion is in an opposite direction to and has larger partial dispersion in a blue range than the first color dispersion. The prism interface may be replaced by an interface of two lenses which interface is a curved surface whose center of curvature is deviated from the optical axis of the reflected light in the auxiliary scanning direction.

摘要： An image reading apparatus with a plurality of line sensors comprises a reference level adjusting circuit for adjusting a level of a dark output outputted from one of the line sensors to a reference level, and a level difference adjusting circuit for progressively adjusting to a minimum a dark output level difference between the reference level adjusted line sensor and a second line sensor adjacent to the former sensor, a dark output level difference between the second line sensor and a third line sensor adjacent to the second line sensor, and so on. When three or more line sensors are used, a level of a dark output outputted from one of the three line sensors which is located at the center of a sensor array of the three sensors is adjusted to the reference level. Alternatively, a level of a dark output outputted from one of three line sensors which is located at one of the ends of a sensor array of the three line sensors is adjusted to the reference level. With such an arrangement, even when a linear array of a plurality of line sensors is used, the resultant image is free from lines and stripes or density irregularity, because the level differences at the channel boundary levels are adjusted to be zeroed.
摘要翻译：具有多个线传感器的图像读取装置包括：基准电平调整电路，用于将从一个线路传感器输出的暗输出的电平调整为参考电平;以及电平差调整电路，用于逐渐调节至最小的黑暗基准电平调节线传感器与与前一传感器相邻的第二线传感器之间的输出电平差，第二线传感器与第二线传感器相邻的第三线传感器之间的暗输出电平差等。当使用三个或更多个线传感器时，从位于三个传感器的传感器阵列的中心的三个线传感器中的一个输出的暗输出的电平被调整到参考电平。或者，将位于三行传感器的传感器阵列的一端的三个线传感器之一输出的暗输出的电平调整到参考电平。通过这样的布置，即使使用多个线传感器的线阵列，由于将通道边界电平的电平差调整为零，所以得到的图像没有线条和条纹或密度不均匀。
