Abstract:
1. An image scanning apparatus comprising: an illuminating device that irradiates illumination; an image sensor that outputs signal charges as image data of an original, including a light receiving part for receiving light, in which the light is an illumination irradiated from said illuminating device and influenced by the original, and includes a transferring unit for transferring signal charges generated at the light receiving part; and a controlling device that instructs said illuminating device to irradiate illumination, and directs a timing to transfer signal charges to said transferring unit under a predetermined condition, wherein: said illuminating device respectively irradiates upon the original as the illumination, light to be shut out other than at the light receiving part of said image sensor and light having a long wavelength not to be shut out other than at the light receiving part of the image sensor; and said controlling device prohibits the light having a long wavelength from being irradiated by said illuminating device during the period in which the image data of the original is being output through the transferring unit of said image sensor.
