    摘要: A light source unit emits first illumination light that includes a first red-light wavelength range and is used to emphasize a first blood vessel and second illumination light that includes a second red-light wavelength range and is used to emphasize a second blood vessel different from the first blood vessel. A light source control unit performs control to cause each of the first illumination light and the second illumination light to be emitted for a light emission period of at least two or more frames and to automatically switch the first illumination light and the second illumination light.

    摘要: First RGB image signals are inputted. Color difference signals Cr and Cb are calculated from the first RGB image signals. In a feature space formed by the color difference signals Cr and Cb, a first process and a second process are performed. In the first process, coordinates which correspond to the first, second, and third observation areas are moved in a parallel manner such that the coordinates which correspond to the second observation area are moved to a reference area that contains the origin point. In the second process, the coordinates which correspond to the first observation area and the coordinates which correspond to the third observation area are moved away from each other.

    摘要: A light source device simultaneously produces violet narrowband light and green narrowband light. A complementary color type imaging device of a complementary color type endoscope outputs first to fourth mixed pixel signals. In a complementary color second processor, a matrix operation unit performs a matrix operation of the first to fourth mixed pixel signals, and produces first and second display signals D1 and D2. A mixed color corrector corrects the first and second display signals D1 and D2 on the basis of relational expressions of “D1′=D1−K2×D2” and “D2′=D2−K1×D1”. K1 represents the ratio of a signal value of the second display signal to a signal value of the first display signal under independent application of only the violet narrowband light. K2 represents the ratio of a signal value of the first display signal to a signal value of the second display signal under independent application of only the green narrowband light.

    摘要: Violet narrowband light Vn and green narrowband light Gn produced by a light source device are supplied to a complementary color type endoscope, and simultaneously applied to an observation object. In a complementary color type imaging device, first mixed pixels and second mixed pixels, which sense both of the violet narrowband light Vn and the green narrowband light Gn, are read out. The light amount ratio Z of the violet narrowband light Vn to the green narrowband light Gn is set in such a range as to make the light amount of the violet narrowband light Vn larger than the light amount of the green narrowband light Gn, and make a signal value of the second mixed pixel higher than a signal value of the first mixed pixel.

    摘要: RGB image signals are inputted. A B/G ratio is calculated from the B and G image signals. A G/R ratio is calculated from the G and R image signals. First, second, and third areas are located in a feature space formed by the B/G and G/R ratios. An equal angular magnification process is performed on an angle in a region R1x including a first reference line passing through the second area. An angle expansion process or an angle compression process is performed on an angle in a region R1y located outside the region R1x. An equal radial-coordinate magnification process is performed on a radial coordinate in a region R2x, which includes a second reference line passing through the second area and intersecting the first reference line. A radial-coordinate expansion process or a radial-coordinate compression process is performed on a radial coordinate in a region R2y located outside the region R2x.

    摘要: Violet narrowband light Vn and green narrowband light Gn produced by a light source device are supplied to a complementary color type endoscope, and simultaneously applied to an observation object. From a complementary color type imaging device, first mixed pixels and second mixed pixels, which sense both of the violet narrowband light Vn and the green narrowband light Gn, are read out. The light amount ratio Z of the violet narrowband light Vn to the green narrowband light Gn is set within a predetermined range based on an optimal light amount ratio Z0 at which the proportion P1 of a violet narrowband light Vn component within a first mixed pixel signal becomes equal to the proportion P2 of a green narrowband light Gn component within a second mixed pixel signal. This improves color separability of an endoscope system.
