1. Increased liability of the system due to the high degree of integration 
2. Reduced space requirement for the electronics, with the advantage of further improving the 
reliability of the system by the far-reaching reduction of external cables and plugs 
3. Programmability of the microprocessor makes it possible to use identical hardware components 
for a wide variety of functions. 
4. The 'intelligence' of the microcomputer permits the optimization of the camera control to an 
extent that has not been possible hitherto. 
The route towards making the RC 10A the optimum camera will now be demonstrated by the example 
of novel functions: 
1. Camera control and operating aide 
2. Service functions 
The microprocessor systems detect and record the momentary exposure situation and the state of the 
camera system. When the RC 10A is in operation, the operator can easily find out at any time 
whether the camera is being used and operated in the most effective way and whether it is in a 
fully functional state. In addition to display the actual state at any time, this is also recorded 
on the aerial photograph. In its simplest form, this registration is effected by recording an 
eight-figure defects code on the film together with the running exposure number. As a further step, | 
quantitative data can also be recorded digitally near the edge of the film. The valency of camera 
control and operating assistance during operation and after registration on the film is shown 
summarily on Figure 4. 
The sequence of each of the various controls during an exposure cycle is shown in Figure 5. Such a 
cycle consists of the time before exposure, exposure, film transport by the amount required for one 
photograph, and the waiting time to the next photograph.
