    • Disclosed are method and device for automatically controlling the time period of photographic development for each specific combination of a photographic developer and a photosensitive material for the purpose of obtaining a substantially same or optimum photographic development result at various temperatures. Through utilization of the knowledge of a certain relation between the time period of photographic development and the temperature of the photographic developer which will produce a same photographic development result, the time period of photographic development is adjusted, for instance, by changing the speed of a conveyor carrying the photosensitive material through the photographic developer. The mentioned relationship may not be always expressed by a linear function with a desired accuracy but may be approximated with a desired accuracy by means of various mathematical functions such as polynomials and irrational functions.
    • 公开了用于自动控制照相显影剂和感光材料的每个特定组合的照相显影时间段的方法和装置,以便在各种温度下获得基本上相同或最佳的照相显影结果。 通过利用摄影发展的时间段与产生相同摄影发展结果的照相显影剂的温度之间的一定关系的知识,可以通过改变摄影发展的时间来调整摄影发展的时间段 传送带通过照相显影剂携带感光材料。 所提及的关系可能不总是由具有期望精度的线性函数表示,但是可以通过各种数学函数(诸如多项式和非理性函数)以期望的精度近似。
