Exposure display device |
摘要 |
An exposure display device for a camera, which can display not only the density of the background to be photographed on a film but also the density of a primary object to be focused with respect to an exposure control value used for exposure control operation. In natural light photography, the brightness of the primary object area at which automatic focus detection is conducted and the brightness of divided object field areas are measured, the density distribution of the primary object area and those of the divided object field areas reproduced on the film are calculated basing on the measurement, and the results are displayed in correspondence to the exposure control value. In flash light photography, the expected brightness of the primary object area and divided object field areas are measured, and the density distribution of the primary object area and object field areas reproduced on the film are calculated and displayed in correspondence to the exposure control value.
