摘要： An operation of an iris filter is carried out on an original image signal representing an image, and the degree of centralization of gradients of the original image signal with respect to a picture element is thereby calculated, each of picture elements constituting the image being taken as the picture element. An image portion, which is associated with a high degree of centralization, in the image is detected in accordance with the calculated degree of centralization. Image emphasis processing is then selectively carried out on the detected image portion. Alternatively, a morphology operation is carried out on an original image signal Dorg by using a multiply structure element Bi and a scale factor &lgr;, and a morphology signal Dmor is thereby obtained. The morphology signal Dmor represents whether each of picture elements constituting the image is or is not the one corresponding to an image portion, at which the original image signal Dorg fluctuates in a spatially narrower range than the multiply structure element Bi. Image emphasis processing is then carried out on the original image signal Dorg and in accordance with the morphology signal Dmor.

摘要： A winding shaft, for use in a printer, which allows a wound recording paper to be easily removed therefrom. The winding shaft includes a shaft main body, a winding portion and a support-removing member. The winding portion, which sandwiches the shaft main body, winds the recording paper therearound. The shaft main body includes a pair of support-removing members, which respectively project from the shaft main body. The two support-removing members are respectively supported on the two side portions of the shaft main body in such a manner that they can be freely rotated about their respective support shafts. A tension-coiled spring is bridgingly disposed between the two support-removing members, so that the two support-removing members remain in standing positions when no external force is applied to them. If the recording paper is lightly rotated in a direction opposite to the winding direction of the recording paper, then the two support-removing members are brought down in the same direction due to an external force applied thereto from the innermost peripheral recording paper. As a result, the innermost peripheral recording paper is loosened, that is, is caused to float loosely from the outer peripheral surface of the shaft main body, thereby enabling the removable of the recording paper from the winding shaft.

摘要翻译： 用于打印机中的卷绕轴，其允许容易从其中去除伤口记录纸。 卷绕轴包括轴主体，卷绕部分和支撑件移除部件。 卷绕轴主体的卷绕部分绕着记录纸缠绕。 轴主体包括分别从轴主体突出的一对支撑移除构件。 两个支撑移除部件分别支撑在轴主体的两个侧部上，使得它们能够绕其各自的支撑轴自由旋转。 张紧螺旋弹簧桥接地布置在两个支撑移除构件之间，使得当没有施加外力时，两个支撑件移除构件保持在竖立位置。 如果记录纸在与记录纸的卷绕方向相反的方向上轻微旋转，则两个支撑件移除部件由于从最内侧的周边记录纸施加到其上的外力而沿同一方向下降。 结果，最内侧的周边记录纸被松动，从而使其从轴主体的外周表面松动地浮动，从而能够从卷轴移除记录纸。

摘要： Unsharp mask image signals having different frequency response characteristics are formed from an original image signal, and band-limited image signals are formed from the unsharp mask image signals. First and second converting processes are carried out on the band-limited image signals, and first converted image signals and second converted image signals are thereby formed. The first converted image signals are integrated, and a signal concerning high frequency components is thereby obtained. Also, the second converted image signals are integrated, the thus obtained integration signal is subtracted from the original image signal, and a difference signal is thereby formed. The difference signal is converted, and a signal concerning low frequency components is thereby obtained. The signal concerning high frequency components and the signal concerning low frequency components are added to the original image signal. Thus the high frequency components of the original image signal are emphasized, and the dynamic range of the original image signal is compressed.

摘要： A morphology operation, with which an image portion having a contour of a predetermined size is extracted from an original image, is carried out on an original image signal Sorg representing the original image. A specific image signal, which represents a characteristic value with respect to the image portion having the contour, is thereby obtained. A specific image emphasis coefficient in accordance with the level of the specific image signal is calculated. An edge signal, which represents a characteristic value with respect to an image edge portion in the original image, is detected. The specific image emphasis coefficient is adjusted in accordance with the edge signal. A new specific image emphasis coefficient obtained from the adjustment is employed as an emphasis coefficient .beta., and a processed image signal Sproc is calculated with Formula (1):Sproc=Sorg+.beta..times.(Sorg-Sus) (1)where Sus represents an unsharp mask signal of the original image signal Sorg.

摘要： In closing processing, maximum value processing is carried out with a structure element on an original image signal, and maximum value signals are thereby obtained as intermediate results and stored in an intermediate memory. The intermediate memory has a storage space of (the same number of lines as that of picture elements constituting the structure element).times.(the number of picture elements lying on one line in the array of picture elements of the original image). Minimum value processing is then carried out with the structure element on the maximum value signals having been stored along one line in the intermediate memory. Each time the minimum value processing for one line in the intermediate memory is finished, the maximum value signals having been stored in the intermediate memory are shifted back by one line, and the maximum value processing is then carried out for one line in the array of picture elements of the original image. The storage space of the intermediate memory is thereby kept small.
