Abstract
An exposure feedback apparatus is disclosed that includes a comparison unit for receiving and comparing image data with a predetermined exposure level and generating a comparison signal indicative thereof, and a multiplexing unit responsive to the comparison signal for supplying the image data to a display output line when the image data is within a desired exposure range and for alternatingly supplying the image data and preselected display data to the output line when the image data is outside of a desired exposure range. In operation, the alternating supply of the image data and preselected display data to the display output line causes portions of a display unit coupled thereto to 'blink' when areas of the imaged scene exceed the predetermined exposure level. Thus, the user is supplied with visual feedback that is indicative of the exposure conditions of the captured image.
