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： Because of using as a light source a halogen lamp which is well stabilized in terms of both the quantity of light and the spectral ratio, it is unnecessary to read shading data whenever the reading of an image is initiated. The shading data can be read with a certain margin at the end of a copy job, when power is being given to an image reader or at given time intervals for making shading correction on the basis thereof. Reading the shading data can be carried out with a certain time margin without detriment to FCOT (First Copy Output Time) and CPM (Copy/Minute); enough time is allowed for acceptance of the shading data, so that data of a plurality of lines can be read and fault values, if any, can be removed therefrom. Therefore, the influences of dust, etc., even if present on the white reference plate, can be eliminated. In addition, since it is unnecessary to accept the shading data at the beginning of a copy job, the white reference plate can be located on platen glass on the tail end side rather than on the lead edge side; the white reference plate can be read under the same illuminating conditions as in reading the original document.
摘要翻译： 由于使用作为光源的卤素灯，其在光量和光谱比方面都是稳定的，因此无论何时启动图像的读取，都不需要读取阴影数据。 阴影数据可以在拷贝作业结束时以一定余量读取，当给图像读取器供电时，或者以给定的时间间隔进行阴影校正。 读取阴影数据可以以一定的时间间隔进行，而不影响FCOT（第一拷贝输出时间）和CPM（复制/分钟）; 允许足够的时间接受阴影数据，从而可以读取多行的数据，并且可以从中去除故障值（如果有的话）。 因此，即使存在于白色基准板上，也可以消除灰尘等的影响。 此外，由于不需要在复印作业开始时接受阴影数据，所以白色参考板可以位于尾端侧而不是前缘侧的压板玻璃上; 可以在与读取原始文档相同的照明条件下读取白色参考板。

摘要： An image sensor is operable in a read state, a rest state, and a stand-by state. Control signal generating means generate a control signal. The control signal has a first constant preset level during the read state, a second preset level during the rest state, and alternates between the first and second levels at a duty ratio during the stand-by state. Drive circuit means transfer current to the image sensor in response to the control signal. Therefore, current is continuously transferred to the image sensor during the read state, no current is transferred during the rest state, and current is intermittently transferred to the image sensor at the duty ratio during the stand-by state.

摘要： A color linear image sensor includes a sensor pixel linear array with a plural number of color filters laid and bonded thereover, a readout circuit and an output processing circuit. The sensor pixel linear array consists of repeat patterns of color pixels linearly arrayed in a preset color order, the repeat patterns being symmetrical with respect to the midpoint of the sensor pixel linear array. The readout circuit reads out image signals line by line from the sensor pixel linear array. The output processing circuit distributes the readout signals into a plural number of color image signal routes, and outputs the readout signals of separated colors. The color linear image sensor thus constructed may be incorporated into an image processing system. The midpoint of the sensor pixel linear array is coincident with the optical axis of a lens of the optical system of the image processing system.
