    • Confirmation of the content of the images recorded on a CD-R or other storage medium is made easier. A data obtaining means obtains plural sets of image data recorded on a digital camera, etc. data storage medium, and an image processing means subjects the obtained image data to image processing and obtains processed image data. The processed image data is recorded onto a CD-R, etc. storage medium by an image recording means. A representative image selecting means selects images representative of the images represented by the image data. Then, thumbnail images of the selected representative images are attached to the surface of the storage medium disk by a representative image attaching means.
    • 记录在CD-R或其他存储介质上的图像的内容的确认变得更容易。 数据获取装置获得记录在数字照相机等数据存储介质上的多组图像数据,并且图像处理装置对所获得的图像数据进行图像处理,并获得处理的图像数据。 经处理的图像数据由图像记录装置记录在CD-R等存储介质上。 代表图像选择装置选择表示由图像数据表示的图像的图像。 然后,通过代表性的图像附着装置将选择的代表图像的缩略图图像附加到存储介质盘的表面。

    • In a digital output service of photographs, smooth operation of an additional recording service is aimed at by letting a user or an operator of a service provider easily understand the number of photographs addable to a storage medium. The free space size of a storage medium is detected each time new or additional recording therein is completed, and information regarding the free space size is indicated to a customer by being recorded on a recording medium corresponding to the storage medium, such as index print for the storage medium. On this occasion, the free space size is indicated as the number of films or exposures such as “6 25-exposure films” (6 (25 Exp)) or “160 exposures” (160) so that a user who is not familiar with expressions in bytes can readily understand it.
    • 在照片的数字输出服务中,通过使服务提供者的用户或操作者容易地理解可添加到存储介质的照片的数量来实现附加记录服务的平滑操作。 每当完成新的或附加的记录时,检测存储介质的可用空间大小,并且通过记录在与存储介质相对应的记录介质上的方式向客户指示关于可用空间大小的信息,诸如用于 存储介质。 在这种情况下,自由空间大小表示为“6 25曝光胶片”(6(25曝光))或“160曝光”(160)的电影或曝光数量,以便不熟悉的用户 字节表达式可以很容易理解。

    • 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.

    • A radiation image signal, which has been obtained by reading out a radiation image having been recorded by use of an irradiation field stop and having an irradiation field thereon, is thinned out at a predetermined rate, and a thinned-out image signal is thereby obtained. The shape and location of the irradiation field are determined in accordance with the thinned-out image signal, and a range of a blackening process is set in accordance with the results of the determination. A blackening process is carried out on the thinned-out image signal with respect to the set blackening process range, and a visible image is reproduced from the thinned-out image signal., which has been obtained from the blackening process. The blackening process range is corrected in accordance with the visible image reproduced from the thinned-out image signal, which has been obtained from the blackening process. The blackening process is then carried out on the radiation image signal and in accordance with the set blackening process range or the corrected blackening process range.

    • Prospective abnormal patterns in a radiation image of an object are detected in accordance with an image signal representing the radiation image. A probability density function of the image signal, which corresponds to a region, that is inward from a contour of each of the prospective abnormal patterns having been detected, and a neighboring region, is formed. Probability density function information in accordance with the probability density function is obtained. A definite prospective abnormal pattern, which is among the prospective abnormal patterns having been detected and has a high level of probability that it will be the true abnormal pattern, is detected in accordance with the probability density function information.
