Abstract:
For the purpose of improving the manipulability at the time of insertion, and improving the ease of observation at the time of removal, according to the movement direction of an insertion portion with respect to a body cavity and a movement mode thereof, an endoscope system includes: an endoscope that is provided with an insertion portion that is inserted into a body cavity and an image acquisition part that acquires, at the distal end of the insertion portion, an image of the inside of the body cavity; an insertion/removal detector that detects a relative movement direction of the insertion portion with respect to the body cavity; an image generator that generates image information suitable for a movement mode of the insertion portion based on the relative movement direction detected by the insertion/removal detector; and an image display part that displays the image information generated by the image generator.
Abstract:
An image processing apparatus receives an image signal and generates a display image having an image range associated with a display area of a display unit from an image based on the image signal. The image processing apparatus includes a position-of-interest-calculating-unit, a frame-out-accuracy-calculation-unit, an alteration-variable-decision-unit and an image-alteration-unit. The position-of-interest-calculating-unit calculates a position of interest as a position of an object of interest in the image. The frame-out-accuracy-calculation-unit calculates a frame-out accuracy representing an accuracy that the position of interest deviates from the image range based on the position of interest and the image range. The alteration-variable-decision-unit decides a processing variable of alteration processing performed with respect to the image in conformity with the frame-out accuracy. The image-alteration-unit performs the alteration processing with respect to the image in conformity with the decided processing variable to generate a signal of the display image.
Abstract:
An image processing system includes an image acquisition unit, a candidate value estimation unit, a band characteristics evaluation unit, an effective frequency determination unit and a candidate value modification unit. The acquisition unit acquires images. The estimation unit estimates, for each pixel of the images, a candidate value of a 3D shape. The evaluation unit calculates, for each pixel, a band evaluation value of a band included in the images. The determination unit determines an effective frequency of the pixel based on statistical information of the band evaluation value. The modification unit performs data correction or data interpolation for the candidate value based on the effective frequency and calculates a modified candidate value representing the 3D shape.
