Abstract
An image scanner allows the reflection from the image on the face containing the image data to read of an original to strike on a one-dimensional image sensor and thus scans and reads the entire image on the original's face. The image scanner includes brightness sensing means for sensing ambient brightness and means for varying the reading speed of the one-dimensional image sensor in accordance with the brightness sensed by the brightness sensing means. In light surroundings, the scanner generates relatively fast clock signals, making the original's face scanning faster according to these clock signals, producing image data signals without saturating their output capacity. In dark surroundings, the scanner generates relatively slow clock signals, making the original's face scanning slower according to these signals, producing image data signals with a satisfactory S/N ratio.
