Abstract: 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.

Moreover, the pair of first crimp pieces are formed into a shape that is along inner walls of the pair of second crimp pieces.

Abstract: A method of determining the acceptability of a press contact of a wire between press contact blades of a terminal. The method includes the steps of storing a reference data of a relationship between displacements of the press contact blades when the wire is brought into press contact with a normal press contact terminal and contact loads between the press contact blades and the core wire; inserting the wire between the press contact blades of the press contact terminal as an object to be inspected; measuring the displacement of the press contact blades caused by the insertion of the wire; and determining the acceptability of the press contact terminal as the object to be inspected by predicting the contact loads between the press contact blades of the press contact terminal as the object to be inspected based on the measured displacements and the reference data.

Abstract: An image reading apparatus having a visible light source for emitting visible light, an invisible light source for emitting invisible light, an imaging optical system for irradiating a document by these light sources to form optical images of the document, and a CCD for photoelectrically converting the optical images of the document turns on the visible light source to acquire a visible light image signal by the CCD. Then, the apparatus turns on the invisible light source to acquire an invisible light image signal by the CCD. After the invisible light image signal is acquired, the apparatus turns off the invisible light source, and turns on the visible light source regardless of whether to read the document.

Abstract: A construction is achieved at low cost which reduces the loss of gradation in a dark portion of an image that has been subjected to gamma correction in accordance with characteristics of a display. In an image reading apparatus, to make it possible to more finely reproduce the gradation in the dark portion, the number of gradations expressed by an signal obtained by a CCD is reduced by performing non-linear gamma correction using a gamma coefficient below one, and the resulting signal is transferred to a computer serving as a host computer. In the computer, the transferred signal is subjected to gamma correction using a gamma coefficient that is an inverse of the gamma coefficient used in the image reading apparatus, thereby canceling out the influence of the gamma correction performed in the image reading apparatus.
