Solid state image pick-up system

A solid-state image pick-up system comprising:

• an image pick-up lens for making incident light from a subject form an image;
• color separating means for separating said incident light beam into a plurality of color components at a given period;
• a solid-state image pick-up device for receiving said subject light separated through said color separating means and for converting the received subject light into a given subject picture signal;
• image pick-up mode selecting means for selecting one of a standard mode for picking up a dynamic picture and a high-sensitivity mode for picking up a still picture;
• control means for controlling said period of said color separating means responsive to an output of said image pick-up mode selecting means;
• and wherein said color separating means is made up of a light source for alternately emitting a plurality of color light beams at a given period to illuminate said subject.

A solid-state image pick-up system comprising:

• a light source for illuminating a subject;
• a rotary filter located between said light source and said subject and including a color filter having a plurality of given color areas arranged in its circumferential direction;
• an image pick-up lens for receiving light from said subject;
• a solid-state image pick-up device for converting said subject light from said image pick-up lens into a given subject picture signal;
• image pick-up mode selecting means for selecting one of a standard mode for picking up a dynamic picture and a high-sensitivity mode for picking up a still picture;
• and
• rotating speed control means for controlling a rotating speed of said rotary filter responsive to an output of said image pick-up mode selecting means.

A solid-state image pick-up system comprising:

• a light source alternately emitting a plurality of color light beams at a give period to illuminate a subject;
• an image pick-up lens for receiving light from said subject;
• a solid-state image pick-up device for converging said subject light from said image pick-up lens into a given subject picture signal;
• image pick-up mode selecting means for selecting one of a standard mode for picking up a dynamic picture and a high-sensitivity mode for picking up a still picture;
• and
• control means for controlling said emission period for said light sources responsive to an output of said image pick-up mode selecting means.
