PURPOSE:To improve the geometrical accuracy of an image of each filter, by synchronizing a filter rotating time in the scanning rate, in a line scanning type solid-state camera. CONSTITUTION:A pulse motor 7 is rotated in the preset speed at a control circuit 9, which receives an output signal of a position detecting photo sensor 8 and a line scanning type solid-state camera 5 is scanned in the external synchronism with a start pulse signal (a). Thus, when the filter 2 is rotated in synchronizing with the line scanning type solid-state camera 5, an optional rate is selected. Further, each output signal when signal detetion marks 101-103 is outputted to a signal processing circuit 6 as start signals (d)-(f). Thus, even if the number of wavelength characteristic provided to the filter 2 is changed, the timing is matched to the scanning of the solid-state camera. |
