In an image acquisition system, which produces at least one image, each of which is scorable with reference to at least one image quality criterion, a control system is provided for optimizing the image quality criterion. Typically, the image quality criterion is at least in-part established by an exposure parameter. When considered as an apparatus, the present invention includes a number of components which cooperate together to automatically and continually adjust the value of the exposure parameter to optimize the image quality criterion. An image acquisition means is provided to obtain one or more acquired images under selected exposure characteristics. A transform system is provided for receiving the one or more acquired images and developing an energy distribution map, or histogram, of at least a portion of the one or more acquired images. A neural network means is provided for maintaining a learned relationship between the image quality criterion and the exposure parameter, and for receiving the energy distribution map of the one or more acquired images, and for automatically providing a corrected exposure parameter, so that subsequent acquired images will be obtained under optimal settings of the exposure parameter. A controller member is provided for supplying corrected exposure parameters, which are the output of the neural network means, to the image acquisition means.

Method and apparatus for image acquisition with adaptive compensation

An operator to host communications interface for managing a manual data storage library. A host processor controls Peripheral Data Storage Devices (PDSDs) in the library. Displayed operator interaction fields are presented by a graphical user interface on the screen of a display device connected to a library manager controller. Library manager program code loaded in program memory in the library manager controller is provided with interface logic, for communicating with external devices, as well as the PDSDs through the host processor. The operator communications interface is an integral component of the library and thus may be used for: alerting an operator of the need to mount or demount a particular data medium; alerting an operator with coherent and succinct messages thus improving the quality of messages provided to operators; and alerting an operator with a minimum number of messages. Additionally, the operator may use the communications interface to access the status of PDSDs and to schedule maintenance activities, such as cleaning of the PDSDs.
