Abstract

PURPOSE: To enable the adjustment to suitable level, by displaying the zebra signal on the entire view finder intermittently, in dark state deficient in exposure.
CONSTITUTION: When it is detected that the luminance signal Y from the luminance signal generation circuit 4 is lower than the reference level set in advance at the variable resistor 6 in the exposure deficiency detection circuit 5, the signal from the circuit 5 opens the first AND gate 8 to feed the output signal from the first frequency division circuit 7 to the second AND gate 9. To this gate 9, the signal from the second frequency division circuit 10 is always inputted, and the signal from the gate 8 is intermittetly outputted from the gate 9. This intermittent output signal is mixed with normal video signal at the mixing circuit 11 and it is fed to the view finder drive circuit to make flash display the signal representing the state of deficiency of exposure intermittently.
