| 摘要 |
<p>A light detecting and measuring device for use with an electronic flash unit comprises a phototransistor, integrating capacitor and diodes connected in circuit to the flash unit. The diodes and capacitor are connected to the phototransistor and responsive to signals from the flash unit for enabling measurement of light by the phototransistor only while the flash unit is operating thus preventing measurement from external light sources.</p> |
