。 A sensor that optically reads a document and converts it into an electrical signal, a memory that holds a correction value that standardizes a line in the main scanning direction of the document read by the sensor, and a correction value of the memory and an output of the sensor. In the image input device, the image input device includes a multiplication circuit for multiplying a signal by a signal, a means for comparing an output of the multiplication circuit with a reference value, and a sequencer for updating a correction value in the memory based on an output signal from the comparison means. An image input device comprising: a control device for performing standardization at a desired position of the image input device.
