    摘要: Upon processing a visible light image signal and infrared image signal respectively obtained by illuminating a transparent document with light beams coming from a visible light lamp for mainly emitting visible light and an infrared lamp for mainly emitting infrared light, and photoelectrically converting optical images of the transparent document, a histogram is generated on the basis of the infrared image signal, a threshold value is calculated based on the histogram, and infrared image signal components equal to or smaller than the threshold value are extracted by comparing the calculated threshold value and infrared image signal components. Visible light image signal components corresponding to the extracted infrared image signal components are interpolated using surrounding visible light image signal components.

    摘要: In a method of controlling an image reading apparatus, which has an illumination unit adapted to irradiate an object with first and second light rays in different frequency ranges, and a light-receiving unit adapted to receive light coming from the object, and to output a signal, and reads an image of the object by moving the illumination unit and light-receiving unit relative to the object, the light-receiving unit outputs a first signal in response to irradiation with the first light ray, and outputs a second signal in response to irradiation with the second light ray. Upon reading image information for one line by the image reading apparatus, the second light ray is controlled to be sequentially turned on at a plurality of timings to sandwich the ON timing of the first light ray, and image signals for one line corresponding to the first and second light rays are obtained by averaging or adding respective pieces of image information obtained at the plurality of timings for each of the first and second signals.

    摘要: To produce a high quality thin film by effectively removing the particles from the emitted substance and the oxygen retained under a high vacuum during the production of the thin film by laser ablation, there is provided a process for producing a thin film on a substrate by laser ablation in a vacuum chamber in which a laser beam is irradiated to a target to cause emission of a substance from the target and allowing the emitted substance to deposit on the substrate to grow a thin film on the substrate by laser ablation, the process including irradiating an ion beam to at least one of the substrate and a plume of the emitted substance formed between the substrate and the target.
