Title: Image processor and image processing method
Inventor: MIYAZAWA NATSUMI
IPC: H04N1/60
Filed: 1998-07-15
Abstract: PROBLEM TO BE SOLVED: To attain high speed processing by automatically discriminating a type of an input image and outputting the image with/without adaptive gradation correction processing depending on the result of discrimination to prevent deterioration in image quality being a side effect of gradation correction. SOLUTION: In the operation of discriminating a type of a received image, a lightness distribution information extract section 301 generates a histogram of lightness based on processing object image data and a color number count section 302 counts number of colors expressed based on combinations of R, G, B of the processing object image data. A feature variable analysis section 303 extracts minimum lightness, maximum lightness and number of peaks where the lightness takes maximum values as feature variables based on a distribution shape of the lightness histogram.  In the case that the lightness distribution is not widely distributed to an all gradation area or the lightness is concentrated on a few specific gradation areas by comparing the feature variables with a prescribed threshold level, it is discriminated that the image is a graphical image and gradation correction processing is stopped. In the case that number of colors is less than a prescribed threshold value, it is discriminated that the image receives processing such as dither processing and the gradation correction processing is stopped.

Title: Friction material
Inventor: KAWABATA MASATAKA
IPC: C09K3/14
Filed: 1999-07-15
Abstract: PROBLEM TO BE SOLVED: To ensure a large friction coefficient and high shearing strength using an organic paper-like base material. SOLUTION: This friction material is composed of a paper-like base material formed of fibrous material, a compound binder formed of at least one of metallic alkoxide and organic group substituted metallic alkoxide and impregnated in the base material, and phenol resin impregnated in the base material. Since the compound binder is exposed to the surface of the base material, the frictional property of the compound binder is manifested at the time of friction to increase a boundary friction coefficient. The permeability of the compound binder into the base material is improved by the presence of the phenol resin to obtain high shearing strength. Flexibility is further improved by the presence of the phenol resin compared to the case of having only the compound binder.  Compliance to an object member is thereby improved, and the friction coefficient is further improved by the enlargement of contact area.
