Abstract
Provided is an image reading apparatus including a reading member that reads a document on which an image is recorded, a calibration process section that performs a shading process to correct unevenness in brightness based on a result acquired in such a way that the reading member reads a preset color, and a heating control section that heats the reading member during a preset period when power is supplied from a state in which power is not supplied.
Claims9
An image reading apparatus comprising:
- a reading member that reads a document on which an image is recorded;
- a calibration process section that performs a shading process to correct unevenness in brightness based on a result acquired in such a way that the reading member reads a preset color and that performs a calibration process based on the image which includes a yellow color image;
- and
- a heating control section that heats the reading member during a preset period when power is supplied from a state in which power is not supplied,
- the reading member including a reading element that reads the document through a transmission member for transmitting a preset color, for each color, the reading element reading the document through a blue color transmission member.

An image reading apparatus comprising:
- a reading member that reads a document on which an image is recorded and that reads a preset reference member when power is supplied;
- a calibration process section that performs a shading process to correct unevenness in brightness based on a result acquired in such a way that the reading member reads a preset color;
- a heating control section that heats the reading member during a preset period when power is supplied from a state in which power is not supplied;
- and
- a period setting section that sets a period in which the reading member is heated based on a result acquired by reading the reference member.
