state imaging devices of the module 22 in accordance with the optical image due to light reception the solid state imaging devices output red r first green g 1 second green g 2 and blue b signals the pre process circuit 25 takes gain control or so of the r g 1 g 2 and b signals according to the synchronization signal the circuit 27 performs a signal processing etc depending upon the instruction from the system control circuit 30 due to this the photographic image is reproduced based upon the r g 1 g 2 and b signals outputted from the solid state imaging element module 22 the image data compressed in a jpeg form is recorded in the external memory fig2 is a structural view of the four plate solid state imaging element module 22 the module 22 has color separation prism that separates incident light into four parts and four solid state imaging devices 22 r 22 g 1 22 g 2 22 b fig3 is a graph exemplifying a spectral characteristic of the blue b first green g 1 second green g 2 and red r portions of light which the color separation prism divided the incident light into four parts as shown in fig2 the color separation prism has a first prism member 40 a second prism member 41 a third prism member 42 a fourth prism member 43 a blue b light reflecting dichroic film 45 provided between the members 40 and 41 a red r light reflecting dichroic film 46 provided between the members 41 and 42 and a second green g 2 light reflecting dichroic film 47 provided between the members 42 and 43.
