Abstract
A digital display system connected to an exposure indicator in a camera to provide a digital display representative of the exposure value in shutter speed by an array of numerical indicators of the block number eight type. When the numerical value of shutter speed is equal to or larger than one second, the indicator which is directly to the right of the least significant digit is utilized to display an indicium representing a 'second' unit as is usual in digital stop watch art by driving a pair of upper-positioned parallel segments in the 'FIG. eight' pattern to be lit serially from the least significant digit.
