摘要： 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.

摘要： At step S1, a red image is acquired from among red, green, and blue images constituting a received endoscopic image. At step S2, M sampling-pixels (where M denotes an integer equal to or larger than 1) are selected from the data of the red image. At step S3, a gradient vector is calculated in order to determine the direction of a gradient in brightness represented by each sampling-pixel. At step S4, the direction of a lumen is detected. At step S5, the detected direction of a lumen is adopted as an inserting direction and arrow information is superposed on an image. The resultant image is displayed on a display device. Control is then returned to step S1, and the same steps are repeated relative to data of the next frame. Consequently, even if the lumen disappears from a field of view for imaging, the inserting direction can be detected.

摘要： An endoscope inserting direction method includes a first step of receiving endoscopic images time-sequentially, a second step of sampling pixels representing low densities from pixels of each of the endoscopic images which are time-sequentially received in the first step and a third step of determining whether or not number of pixels representing low densities which are sampled in the second step is equal to or larger than predetermined number of pixels. In a fourth step, if the number of pixels representing low densities is determined to be equal to or larger than the predetermined number of pixels in the third step, a position of the barycenter of the pixels representing low densities is obtained, and based on a change in the position of the barycenter of the pixels representing low densities of the time-sequentially received endoscopic images, a direction of a shift in the time-sequentially received plurality of endoscopic images is detected. In a fifth step, an endoscope inserting direction, in which an endoscope should be inserted, on the basis of the result of the detection performed in the fourth step is determined.
