Abstract: An image recording apparatus which includes a time-serial image recording arrangement for recording time-serial images of an object. The apparatus also includes an outputting arrangement capable of outputting an image information data of at least a part of the time-serial images to be recorded or having been recorded by the time-serial image recording arrangement, which is used as a standard for observing variations in the time-serial images of the object which occur with lapse of time. The outputting arrangement includes an extracting arrangement for extracting a selected feature of at least one image among the time-serial images as the image information to be a standard of the position and a composing arrangement for composing and outputting image information of the selected feature extracted by the extracting arrangement and for composing and outputting the time-serial images.

Abstract: An endoscopic system comprises an endoscope system, an endoscopic position detecting apparatus, and an image processing apparatus. The endoscope system enables endoscopic examinations. The endoscopic position detecting apparatus detects the three-dimensional positions of the distal part of the endoscope in a body cavity. The image processing apparatus estimates the shape of an object entity visualized by the endoscope. The image processing apparatus is used as a means for grasping the shape of an object entity in a body cavity. For this purpose, the insertion unit of an electronic endoscope is inserted into the body cavity of a patient lying down on a patient couch. Specifically, a main unit of the image processing apparatus is connected to a video processor over a cable, and receives an image signal (R, G, and B signals and a sync signal) sent from the video processor.

Abstract: Insertion of a probe comprising an array of 16 source coils through a forceps channel of an electronic endoscope prepares the source coils in the insert of electronic endoscope for use in monitoring work objects. To a bed where a patient lies, are mounted two sets of sensor coils crossing at a right angle to each other, each of which comprises at least four single core coils with a common central axis placed on the same line in the same direction. A control section of the system gives signals with radiofrequencies (driving signals) through source cables to the source coils, to excite the source coils to generate magnetic fields around them.

Abstract: An image recording apparatus which includes a time-serial image recording arrangement for recording time-serial images of an object, and still image filling arrangements for recoding a still image. The apparatus also includes an outputting arrangement capable of outputting an image information data of at least a part of the time-serial images to be recorded or having been recorded by the time-serial image recording arrangement, which is used as a standard for observing variations in the time-serial images of the object which occur with lapse of time. The outputting arrangement includes an extracting arrangement for extracting a selected feature of at least one image among the time-serial images as the image information to be a standard of the position and a composing arrangement for composing and outputting image information of the selected feature extracted by the extracting arrangement and for composing and outputting the time-serial images.

Abstract: The position of the same point on each of the images of a single object formed by the imaging means of an endoscope is detected, and shift maps between the respective images are formed using the detected positions. Each of the imaging positions of the imaging means is estimated from the shift maps, and a relative shape of the object is then estimated from the imaging positions. Since a relative shape of the object is estimated using the correlation between the respective images, a relative shape of the object can be estimated even when not only the imaging means but also the object are moved. An absolute shape of the object can also be estimated using a length as a reference value.

Abstract: A group of vectors are set to transform each signal of an endoscopic image resolved into a plurality of color signals into a plurality of new color signals based on statistical characteristics of the image. Also, the color signals of the endoscopic image are transformed into new color signals by a matrix operation using the group of vectors for the new color signals. After filtering is applied to the plurality of new color signals, the plurality of new color signals are transformed into a plurality of original color signals by a matrix operation using an inverse matrix of the matrix used in the matrix operation.

Abstract: This electronic endoscope apparatus comprises an elongate insertable part, two image forming optical systems provide in the tip part of the insertable part and an integrated imaging device provided in the tip part of the insertable part and having two imaging regions in which object images are formed by two image forming optical systems. The imaging device has, for example, one solid state imaging device having two imaging regions or has two solid state imaging devices made integral.

Abstract: An apparatus is disclosed which includes a first and a second optical guides inserted in an elongated insertion portion thereof, and which can transmit an optical image, and an optical system with a function of imaging at the end surface of the optical guide. By transmitting an illuminating light from the other end surface to the portion to be observed through one of the optical guides, the portion to be observed is illuminated. While, the optical image transmitted through the other optical guide is introduced into an ocular system or an imaging system. By changing the functions performed by these optical guides, the stereoscopic observation and stereoscopic imaging can be realized.

Abstract: An endoscope video apparatus has an endoscope including a solid-state image sensor, for outputting an endoscopic image signal, a video processor for processing the image signal supplied from the solid-state image sensor and outputting a video signal, an image file unit for recording the video signal, and an input section for inputting retrieval data corresponding to the video signal recorded in the image file unit. A control section discriminates the presence/absence of retrieval data input from the input section. A control circuit operates an alarm unit by discrimination data representing the absence of retrieval data.
