摘要： A monitor camera is provided with a control device which carries out a predetermined process in response to an input of a trigger signal. The control device has an arrangement in that continuous images are successively inputted from a camera unit thereto and in that a detection of a moving object is carried out by detecting a change in images in a moving-object detector. When no change in images is detected by the moving-object detector within a predetermined time after the input of a trigger signal from a detection sensor to a trigger signal input unit, the control device determines the trigger signal inputted to the trigger signal input unit as valid. Then, only when the valid trigger signal has been detected, an abnormality process is carried out. Consequently, it is possible to prevent the abnormality process from being performed upon erroneous detection of a normal state as an abnormal state.

摘要： A digital arithmetic operation circuit includes a plurality of arithmetic operation blocks, a control signal generator and a selector. The plurality of arithmetic operation blocks receive a plurality of digital input signals and perform different arithmetic operations on the received digital input signals, in parallel, to output operation result signals. The a control signal generator receives a plurality of digital input signals and generates a control signal based on the digital input signals. The selector selects one of the operation result signals, in response to the control signal, to output the selected operation result signal. After the control signal generator supplies the control signal to the selector, the selector outputs the selected operation result signal as soon as the selected operation result signal is supplied to the selector.

摘要： A servo signal processing apparatus for processing a servo signal corresponding to servo information from a servo area on a recording medium for controlling a head. The servo area includes a servo mark area for storing a servo mark indicative of a head of the servo area, a gray mark area for storing a gray mark indicative of a head of information for position control for the head, and a gray code area for storing information. An A-D converter converts the servo signal to digital data. A digital filter filters the converted data based on a sampling clock, and outputs the filtered digital data. A servo mark detector detects a servo mark based on a continuity of a first predetermined logical value. A gray code decoder detects a gray code based on a continuity of a predetermined logical value. The gray code decoder decodes information stored in a gray code area following the detected gray mark.
