Abstract
An image reading method for an image recording system which reads an image with an image reader in the form of photoelectric signal conversion devices, converts the resulting analog data into digital data, and prints out the digital data with a printer. One line of image is read a plurality of times by the image reader and the resulting image data are sequentially stored. Even when the image data storing time and a fixed one-line scanning period are different from each other, the image can be read and outputted without changing the quantity of light to be applied to the image reader, i.e., simply by compensating for the difference between the storing time and the fixed scanning time. The compensation is implemented by multiplying one line of data stored by a time ratio of the fixed period to the difference, or adopting all the data inclusive of those associated with the difference, or discarding the data associated with the difference, or adopting only valid data, and then averaging the resulting data by division.
