发明名称 PHOTOMETRY DEVICE HAVING STROBOSCOPIC OPTICAL CONTROLLER
摘要 PROBLEM TO BE SOLVED: To provide a photometry device having a stroboscopic optical controller for enabling proper exposure irrespective of difference of light reflex ratio for subjects. SOLUTION: The color measuring accuracy and stroboscope exposure accuracy are enhanced by providing photometric means 9G, 9B, 9R for measuring colors of a subject by pre-emitting a stroboscope in the case of stroboscopic photography and measuring stroboscopic light to be reflected from the subject in the case of pre-emission, a reflection influence compensation value calculating means for calculating a reflection influence compensation value of the stroboscopic light based on the colors of the subject measured by the photometric means for measuring color and a control level adjusting means for determining the proper exposure based on the calculated reflection influence compensation value, in an automatic stroboscope 28 constituted so as to radiate the stroboscopic light toward the subject, to measure the stroboscopic light to be reflected from the subject, to compare exposure to be obtained with proper exposure and to stop emission of the stroboscopic light when the exposure reaches the proper exposure.
