ABSTRACT:
A light emitting indicator for a camera includes an absolute value circuit for increasing the brightness of the light emitting indicator element with decrease of the scene brightness when the scene brightness is below a predetermined level. Thus, the amount of light emitted from the light emitting indicator and falling on the photocell detector is increased to compensate for the undesired decrease of the total amount of light incident upon the photocell detector which would otherwise result in measurement of too low scene brightness. This increasing light from the indicator element precludes the setting of an undesirably extended period of exposure time.
