Abstract: A liquid discharge head includes a liquid discharge substrate that has a discharge-orifice row, pressure generating elements, and pressure chambers. The liquid discharge head discharges a liquid in a block-by-block manner using sequential driving. The discharge-orifice row is disposed so as to incline at an angle ?=Arctan (d1/d2) relative to a direction extending orthogonal to the conveyance direction of the medium, in which d1 (?m) is a disposition spacing of the discharge orifices in the discharge-orifice row in the conveyance direction and d2 (?m) is a disposition spacing of the discharge orifices in the discharge-orifice row in the direction orthogonal to the conveyance direction. A partition wall is formed between adjacent pressure chambers so as to separate the adjacent pressure chambers from each other. The partition wall has a communicating portion that communicates the adjacent pressure chambers with each other.

Abstract: A light source apparatus for endoscopic imaging includes a light source for emitting at least narrow band blue light and narrow band green light, to illuminate an object in a body cavity. The light source is changeable over between field sequential lighting and simultaneous lighting. The light source, upon setting of the field sequential lighting, emits the narrow band blue light and narrow band green light in a discrete manner, and upon setting of the simultaneous lighting, simultaneously emits the narrow band blue light and narrow band green light. A connector is connectable with an endoscope having a complementary color image sensor of yellow, magenta and cyan, for imaging the object. A controller sets the field sequential lighting assuming that the endoscope is connected to the light source and assuming that the light source is used for emitting the narrow band blue light and narrow band green light.

Abstract: RGB image signals are inputted. B/G ratio is calculated based on B image signal and G image signal. G/R ratio is calculated based on the G image signal and R image signal. In a feature space formed by the B/G ratio and the G/R ratio, an expansion process and a compression process are performed. In the expansion process, an angle between a first center line and coordinates in a specific region, which contains the first center line, is changed at an angle change rate Wnx. In the compression process, an angle between the first center line and coordinates outside the specific region is changed at an angle change rate Wny smaller than the angle change rate Wnx.

Abstract: RGB image signals are inputted. B/G ratio is calculated based on B image signal and G image signal. G/R ratio is calculated based on the G image signal and R image signal. In a feature space formed by the B/G ratio and the G/R ratio, a first process is performed. In the first process, a difference between coordinates in a first observation area and coordinates in a second observation area is increased. The first observation area mostly contains coordinates corresponding to a portion (of an object) infected with H. pylori. The second observation area mostly contains coordinates corresponding to a portion (of the object) in which eradication of the H. pylori infection has been successful.

Abstract: Image observation reports and medical images are displayed correlated to each other. A second keyword group is obtained, by detecting phrases that match keywords of a first keyword group that represent organs or pathologies from within image observation reports. The organs or pathologies represented by the first keyword group are automatically detected from within medical images, and a third keyword group that includes keywords corresponding to the detected organs or pathologies is obtained. Common keywords that match among keywords within the second and third keyword groups are obtained. Link data that correlates the organs or pathologies corresponding to the common keywords are generated for each common keyword. The common keywords and indicia that represent the organs or pathologies corresponding to the common keywords are displayed correlated to each other.
