For improving picture quality in auto-focus control, image processing deviceadjusts output picture imaged by image pick-up elementand displayed by a display section, comprises storage sectionfor storing predetermined de-focus threshold value of variation amount of intensity value of output picture; first adder sectionfor calculating intensity value time difference variation amount between intensity value of output picture being input and intensity value of the predetermined-time previous output picture before the output picture is input; and variation amount comparison sectionfor comparing intensity value time difference variation amount and de-focus threshold value, wherein when variation amount comparison section determines that intensity value time difference variation amount is less than de-focus threshold value to be a comparison object, intensity value of output picture after being adjusted is calculated by subtracting intensity value time difference variation amount from intensity value of output picture being input.

Imaging sensing device, image sensing processing device, and image processing method

For preventing frequent use of auto-focus control and also for acquiring stable in-focus positions for target-objects, this invention comprises system control sectionhaving a second mode to drive magnification adjustment lensor focus adjustment lensupon a user command, and a third mode to transition to a first mode under pre-determined conditions in the second mode, and to set in-focus states of a lens group, wherein system control sectionstores a reference target-object distance in reference target-object distance storage sectionwhen focus adjustment lensis driven by user commands in the second mode, drives focus adjustment lensnot based on a current target-object distance but the lens in-focus trajectory data to retain the reference target-object distance when the magnification adjustment lensis driven by user commands, and re-transitions to the second mode without updating the reference target-object distance, after the third mode.

Image sensing device, image sensing device control method, and program for the control method

In order to obtain stable lens positions to have an object imaged in focus when the temperature of lenses changes, an imaging device of the present invention comprises a system control sectionhaving a imaging mode and a correction mode, the imaging mode in which a group of lensesare controlled and moved to focusing positions for a predetermined distance at first and are further moved to correct the focusing positions for the predetermined distance to the object during imaging according to the temperature compensation data, the correction mode in which the group of lensesare controlled and moved to have the temperature compensation data corrected when the temperature change is larger than or equal to a predetermined temperature difference, a correction coefficient calculation sectionfor calculating the correction coefficient to correct the temperature compensation data based on first focusing positions of the group of lenses to which the group of lenses are moved according to the temperature compensation data before corrected and second focusing positions of the group of the lenses to which the group of the lenses are automatically moved from the first focusing positions to have the object the predetermined distance away imaged in focus based on the focus evaluation value under a condition under which a moving range of the group of lenses is restricted, when the system control section is on the correction mode, a temperature compensation data correction sectionfor correcting the temperature compensation data to be used for the imaging mode based on the correction coefficient calculated by the correction coefficient calculation section.

Imaging device

Disclosed herein is an information recording/reproducing apparatus that includes a first and a second recording/reproducing modules, a buffer memory to store information temporally, and a control module that switches between a first mode and a second mode when the information is dubbed from the first recording/reproducing module to the second recording/reproducing module. In the first mode, information in the first recording/reproducing module is reproduced and stored in the buffer memory. In the second mode, the information stored in the buffer memory is recorded in the second recording/reproducing module. The apparatus further includes a temperature detecting module. Depending on the temperature detected by this module, the apparatus changes the movement of the second recording/reproducing module in the first mode and the movement of the first recording/reproducing module in the second mode.

Information recording/reproducing apparatus

A terminal switching apparatus is connected between an information processing apparatus and a plurality of operating terminals for performing on-line operations and at least one spare terminal used in place of an operating terminal at the time of a failure, and relays on-line data therebetween. The terminal switching apparatus includes storage devices provided for the operating terminals and spare terminal, respectively, for storing on-line data including real-time screen data of the operating terminals and the spare terminal, and a control section with which during an on-line processing, the on-line data is stored into the storage device and with which at the time of detection of a failure in an operating terminal, the contents of the storage device for the failing operating terminal are copied into the storage device for the spare terminal so that the spare terminal continues the on-line processing.

Terminal switching apparatus and method

An automatic operation control system for controlling the automatic operation of a computer system, stores in a storage unit the status informations of hardware configuration and software configuration of a computer system, a running event of the operating system and application programs, and an operation event of the computer system, and supplies a procedure for an operation command to be executed in accordance with the configuration information and the occurred event.
