US 7,023,587 B2 · Image scanning apparatus, recording medium which stores image scanning programs, and data structure

Abstract

The present invention provides an image scanning apparatus having an illuminating device which irradiates illumination, an imaging element which has a light receiving part for receiving light and for generating signal charges, in which the light is an illumination irradiated from the illuminating device and influenced by the original, and has a transfer part for transferring the signal charges, and a controlling device which indicates timings at a predetermined state used to transfer signal charges generated by the light receiving part of the imaging element. In addition, the present invention provides an image scanning apparatus having an illuminating device, an imaging device which reads out signal charges generated by the light receiving part and outputs the signal charges as image data of the original, and a controlling device that prohibits illumination from irradiating in the illuminating device while image data of the original is output from the imaging device.

Dependent claims

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.
