Image reading apparatus which corrects for a reading error caused by reading an image at a continuously-variable image reading density with staggered line image sensors |
摘要 |
An image reading apparatus which has position deviated line sensors. The line sensors are formed by charge coupled devices which are arranged in two staggered rows. The signal from one of the charge coupled devices is delayed for a predetermined period corresponding to the distance between the rows, the speed of scanning and the reading density of the original. An actual timing deviation is calculated to delay one signal relative to the other so that the two signals will be output at the same time.
