ABSTRACT:
A diagnostics system that performs checking, adjustments and other services on a recording apparatus. The system includes an imaging unit having a CCD line sensor assembly, a first board for processing dot sequential color video signals from the CCD line sensor assembly to produce them as digital signals, a second board for converting the dot sequential color video signals from the first board into simultaneous color video signals and for performing shading correction, a third board for performing predetermined image processing on the output from the second board, a fourth board for receiving video signals branched from the third board at predetermined positions to perform predetermined edit processing on the received video signals which are returned to the third board, an image output terminal for receiving the output from the third board, a film projector for projecting a film image, and a user interface. The second board includes a CPU, which performs diagnosis or adjustments on the first through fourth boards and the film projector on the condition that predetermined procedures have been taken on the user interface.
