Title:
CONTROL METHOD FOR TRANSMITTING LIGHT-AMOUNT AND TV CAMERA APPARATUS USING THE METHOD
Document Type and Number:
Japanese Patent JP2002204391
Kind Code:
A
Abstract:
To reproduce video signals of subject parts, except subjects in a high brightness level range, from moving subjects with more fidelity.
In a control method for transmitting light-amount, the high brightness level range is detected, a range to become a high brightness level is predicted by temporal changes of the detected range to control for a reduction of light-receptive light-amount in which the light within the predicted range is received on a light-receiving surface.
