摘要： In a radiation image read-out method and apparatus, a stimulable phosphor sheet carrying a radiation image stored thereon is exposed to stimulating rays which cause the stimulable phosphor sheet to emit light in proportion to the stored radiation energy, and the emitted light is photoelectrically detected. When radiation image read-out is conducted on a stimulable phosphor sheet subjected to subdivision image recording carried out by exposing many subdivisions on the stimulable phosphor sheet respectively to a radiation in radiation image recording, the respective subdivisions are discriminated on the basis of information on subdivision image recording. Conditions of image processing are determined for the respective discriminated subdivisions, and are adjusted for the respective subdivisions when image processing is conducted.

摘要： Test image information is recorded on a test recording medium and the test recording medium is scanned with a light beam to produce an image signal in each of two modes in which the test recording medium is oriented such that a prescribed line on the test recording medium extends in a main scanning direction and an auxiliary scanning direction substantially normal to the main scanning direction respectively in the two modes. A signal level distribution A(x) is determined along the prescribed line of a signal indicative of a logarithmic function of an output signal from a light detector when the prescribed line extends along the main scanning direction, and a signal level distribution B(x) along the prescribed line of a signal indicative of a logarithmic function of an output signal from the light detector when the prescribed line extends along the auxiliary scanning direction (x indicates a pixel position on the prescribed line). Shading characteristics of an image information reading apparatus along the main scanning direction are determined based on the difference A(x)-B(x) between the signal level distributions A(x) and B(x).

摘要： In a radiation image read-out method and apparatus, preliminary read-out is conducted prior to final read-out for adjusting read-out conditions in the final read-out and/or image processing conditions for a radiation image stored on a stimulable phosphor sheet. When the radiation image is read out from the stimulable phosphor sheet subjected to subdivision image recording, an image signal at a subdivision unexposed to a radiation is eliminated from preliminary read-out image signals, which are obtained by the preliminary read-out, on the basis of information on the subdivision image recording. The read-out conditions in the final read-out and/or image processing conditions are adjusted based on the remaining preliminary read-out image signals.

摘要： In a radiation image recording and reproducing system, preliminary image recording is conducted by exposing a stimulable phosphor sheet to a radiation prior to object image recording without making the radiation pass through an object, and a preliminary image signal obtained by image read-out from the stimulable phosphor sheet after the preliminary image recording is stored. After the object image recording, a visible image of the object is reproduced by use of an electric image signal obtained by subtracting the stored preliminary image signal multiplied by a predetermined constant from an electric image signal obtained by image read-out from the stimulable phosphor sheet subjected to the object image recording.

摘要： By providing a network photograph service, prompt service can be provided to a customer without losing the advantages of easier understanding of where to access when placing an order and easier collective data management. A service center receiving an order of a printing service, and a minilab or a special laboratory spread across a plurality of places, are able to communicate through a network. A center server in the service center selects and assigns which photo-finishing laboratory will print the ordered picture, in response to order information transferred from a customer via the network. Thus, the printing processing can be carried out by a photo-finishing laboratory specified by the customer, instead of at the center server.
