PURPOSE:To simply discriminate that measurement has been carried out and to make it possible to simply confirm the set value and operation value among a plurality of displayed values, by starting the operation of a photometric means in accordance with a manual operation by a photometry start means. CONSTITUTION:A photometry start means CPU allows the operation of photometric means C1, C2 to start in accordance with the manual operation and a combination of a parameter to be preset and a parameter to be operated is selected by a selection means SW13. An operation means CPU performs predetermined operation from the set value corresponding to a preliminarily selected parameter and a photometric result to calculate the operation value in correspondence to a predetermined parameter and a display means LCD displays both of the set value and the operation value. At this time, the means LCD is controlled by a display control means CPU and a synchronizing driver DV1 so as to blank the display corresponding to the operated parameter for a moment before the operated value is displayed from the start of the operation of the means C1, C2. Therefore, the display in accordance with the operated parameter becomes blank for a moment in accordance with the operation of the means C1, C2.
