MULTI-STANDARD-SYSTEM OBSERVATION CAMERA AND MONITORING SYSTEM USING ABOVE CAMERA

摘要

PURPOSE: To reduce electric noises and to improve reliability by generating a clock instruction signal by setting a time count resource outside form a line synchronization signal and a sampling frequency signal, corresponding to a selected television standard. CONSTITUTION: A detector 24 for vertical scan includes a large number of sensor elements arranged on plural columns, and the length of strip 4 is specified by its full length. Then, when vibrating a related vertical scanning mirror 2 around a horizontal axial line AA', the image of height (h) formed from a convergent system 3 is analyzed, while vertically moving along with a direction DV on the strip 4. In this case, when the plural sensors are arranged as prescribed, a sampling matter and a sensitivity matter are satisfied. Furthermore, a sequencer 22 generates a clock instruction including the time count resource, and it is set from the outside by the line synchronization signal and the sampling frequency signal corresponding to the selected television standard. Since the instruction signal can be generated inside a low-pitched sound maintaining device, electric noises are reduced and reliability in control is enhanced.
