    摘要: An image recognition apparatus operates on data of a color image to obtain an edge image expressing the shapes of objects appearing in the color image, the apparatus including a section for expressing the color attributes of each pixel of the image as a color vector, in the form of a set of coordinates of an orthogonal color space, a section for applying predetermined arrays of numeric values as edge templates to derive for each pixel a number of edge vectors each corresponding to a specific edge direction, with each edge vector obtained as the difference between weighted vector sums of respective sets of color vectors of two sets of pixels which are disposed symmetrically opposing with respect to the corresponding edge direction, and a section for obtaining the maximum modulus of these edge vectors as a value of edge strength for the pixel which is being processed. By comparing the edge strength of a pixel with those of immediately adjacent pixels and with a predetermined threshold value, a decision can be reliably made for each pixel as to whether it is actually located on an edge and, if so, the direction of that edge.

    摘要: A method of forming a thin polycrystalline silicon film and a thin film forming apparatus allowing inexpensive formation of a thin polycrystalline silicon film at a relatively low temperature with high productivity. More specifically, a method of forming a thin polycrystalline silicon film and a thin film forming apparatus in which a state of plasma is controlled to achieve an emission intensity ratio of hydrogen atom radicals (H&bgr;) of one or more to the emission intensity of SiH* radicals in the plasma. The thin film forming apparatus of a plasma CVD type includes a deposition chamber accommodating a deposition target substrate, a discharging electrode for plasma formation connected to a discharging power source, a gas supply device for supplying a gas and an exhaust device, and further includes an emission-spectrometer and a probe measuring device as well as a control portion for controlling at least one of the power supply, the gas supply and gas exhausting, for maintaining a desired state of plasma based on information detected by them.

    摘要: A photopolymerization initiator comprising an iodonium salt compound; and a photocurable composition containing the compound. The composition is a photocurable cationic composition which cures in a short time upon irradiation with actinic energy rays. They are based on the following findings: (1) a colorless lowly toxic iodonium salt compound can be easily synthesized in high yield when a specific substrate is used as a starting material; (2) a photocurable composition curing in a short time to give a cured article having excellent material properties is obtained by using the iodonium salt compound in combination with a sensitizer; and (3) a highly sensitive photocurable composition which upon irradiation with actinic energy rays cures in a short time to give a cured article having excellent material properties is obtained by using a compound having a group functioning as a cationic photopolymerization initiator, a sensitizing group accelerating the phtoinitiated cationic reaction, and a cationically polymerizable group in the same molecule.
