发明名称 Movie camera with strobe light
摘要 A movie camera having: a strobe light for illuminating a subject; a shutter speed switching circuit for changing speeds of a shutter for the charge coupled device (CCD); a white balance switching circuit for adjusting the balance between color signals; an automatic gain control (AGC) circuit for adjusting amplifying gain for an image signal; a control circuit for energizing the shutter speed switching circuit so that a flash of the strobe light is terminated within the storing time of the CCD by changing the shutter speed to a higher speed, for energizing the white balance switching circuit so that the white balance is adjusted to coincide with the color temperature of the strobe light, and for fixing the gain of the AGC circuit. Accordingly, clear pictures having uniform brightness are obtained in each shot by terminating a flash of the strobe light within the storing time of CCD and by switching the shutter speed to a higher speed, and fluctuation of the brightness of pictures shot after a flash of the strobe light is prevented by fixing the gain of an AGC circuit and by making the white balance coincide with the color temperature of the strobe light.
