Abstract: When the user inputs at least four points that designates the path on the surface of a three-dimensional shape represented by three-dimensional shape data, groups of three points in which two points are commonly included in two groups are formed from the input points. Each group of three points defines a plane including the three points. The line of intersection of each plane and the surface of the three-dimensional shape is obtained to calculate lengths of the line of intersection between the adjacent two points of the three points in each of the groups. Two lengths between the two points that are commonly included in two groups along two different lines of intersection are obtained for one length of the path between the two points. As a result, the average of the two lengths is estimated as the length of the path between the two points. The total length of the path is obtained according to the estimated lengths and lengths along lines of intersection.

Abstract: When a multi-level image is recovered from a pseudo-half-tone bi-level image, a smoothing component and an edge emphasis component obtained on pixels around a specified pixel to be recovered is mixed. The edge emphasis is performed only when the monority pixels exist around the specified pixel. As to the edge emphasis, a narrow line is recovered by using a pair of windows of width of one pixel of the two sides in the edge emphasis direction to obtain an edge emphasis component of width of one pixel in the edge emphasis direction. As to the mixing, the size of the windows for smoothing and the size for the edge emphasis are made almost equal to each other. In order to prevent erroneous edge detection, edge emphasis is judged by using a region including the specified pixel and another without the specified pixel. Erroneous detection of an image of high spatial frequencies can be prevented by using four detection regions.

Abstract: In an image processing apparatus for processing inputted binary image data including a first area in which data are binarized by a pseudo half-tone binarizing method and a second area in which data are binarized using a predetermined threshold value by a non-half-tone binarizing method, there is calculated a number of adjacencies representing an adjacency state of the same kind of pixels located within a block area composed of a plurality of pixels including a specified pixel to be processed. Further, there is judged whether each pixel of the inputted binary image data is included in the first area or the second area, based on the calculated number of adjacencies.

Abstract: In the electronic sort of a digital copying machine, image data of a document consisting of a plurality of sheets are read and compressed to bi-level data in a memory. The compressed image data are recovered to multi-level data successively. When a plurality of copies of the document are produced, the recovery action is repeated by the number of the copies. In a facsimile machine combined with a digital copying machine, bi-level image data for the automatic reduction transmission are recovered first to multi-level image data, and the density of the multi-level image data is changed for the reduction. Then, the multi-level data are converted to bi-level data for facsimile transmission. In a digital two-color copying machine, multi-level image data of the second color of the two colors to be recorded later has to be synchronized to those of the other in correspondence to the delay of the recording time between the two colors.

Abstract: An image reading apparatus for reading an image of an original while transporting the original from an original tray to an image reading position. When an original once read has to be read again due to some trouble, the original is automatically transported to an original tray provided upstream of the reading position so that the original can be automatically read again without operator intervention.
