<p>A frame sequential-method color camera system capable of obtaining a high-precision image by combining a frame-sequentially emitting lighting system with a light emitting strobe or a light emitting diode including red, green and blue visible lights and IR-light or UV-light invisible beam to complete with two frames. The color camera system comprises a color camera (1) including a spectral optical system for spectrally separating the optical image of an object incident from a lens (8) into two directions, two solid-state image sensors (CCD) (3a, 3b) for converting the respective portions of the optical image separated into two directions into electric signals, an electronic shutter control means (6) for sequentially exposure-controlling the two solid-state image sensors (3a, 3b) for every one frame period, within time equivalent to 1/2 frame, and at an interval not allowing mutual overlapping, and a light emitting synchronized signal outputting means for outputting a light emitting synchronized signal in synchronization with the sequential exposure control by the electronic shutter control means (6), and a lighting system (20) for emitting by sequentially switching lights of a plurality of colors different in wavelength band in synchronization with the exposure control by the solid-state image sensors (3a, 3b) on receiving the light emitting synchronized signal by the color camera (1).</p> |
