美国普拉公司自1937年以来一直经营一步摄影器材,有较强的相机生产实力。七十年代末该公司研制成了第一台超声自动测距的一步相机,现正在研制全电子一步摄影相机。这是照相将逐渐转向电子过程的又一信号。过去所谓的电子相机只是用电或电子进行曝光控制的,而其影象仍然是通过光化学反应记录在光敏胶片上的。这里所谓的全电子相机是指照相的全过程都是用电子进行的,而无需再用胶片。相机共包括四个基本部分:1,记录装置:记录由透镜产生的光
US Pula company has been operating since 1937 a step photographic equipment, a strong camera production strength. In the late seventies, the company developed the first step camera for automatic ultrasonic distance measurement and is now developing a full electronic one-step photographic camera. This is yet another signal that photography will gradually shift to electronic processes. In the past, so-called electronic cameras were controlled by electricity or electrons only, and their images were still recorded on photosensitive film by photochemical reaction. The so-called all-electronic camera here refers to the whole process of photography are carried out by electronic, without the need to re-use film. Camera consists of four basic parts: 1, recording device: record the light generated by the lens
