The read / write control data stored in the non-volatile RAM 44 is referred to the read prohibition code of the item m (step S123), and it is determined whether or not the read is prohibited (step S124). If reading is prohibited (Y), the CPU 41 sets the setup card 2
The adjustment data of the item m read from Step 5 is invalidated (Step S125), and the adjustment data stored in the nonvolatile RAM 44 is not updated. On the other hand, if the reading is not prohibited (step S124; N), the CPU 4
1 stores the adjustment data of the item m read from the setup card 25 in the nonvolatile RAM 44 so as to replace the adjustment data of the item m already stored in the nonvolatile RAM 44, and stores the adjustment data in the camera-integrated VTR. (Step S126). When step S125 or step S126 ends, C
The PU 41 determines whether or not m = n (where n is the number of adjustment items) (step S127). If m = n (N), m is incremented by 1 (step S12).
8) Returning to step S123, the processing of steps S123 to S127 is performed for the next item. CPU 41
When m = n (step S127; Y), the reading process ends, and the routine returns to the routine shown in FIG.

FIG. 10 is a flowchart showing the contents of the write processing (step S109) in FIG. In this writing process, first, the CPU 41 sets m = 1 (step S131), refers to the write inhibition code of the item m in the read / write control data stored in the nonvolatile RAM 44 (step S132), and writes the data. It is determined whether it is prohibited (step S133). If the writing is prohibited (Y), the CPU 41 does not write the adjustment data of the item m stored in the nonvolatile RAM 44 to the setup card 25 (step S1).
34). On the other hand, if the write is not prohibited (step S133; N), the CPU 41
The adjustment data of the item m stored in M44 is written in the setup card 25, and the setup card 2
5 is updated (step S135). When step S134 or step S135 ends,
The CPU 41 determines whether m = n (step S13).
6) Unless m = n (N), m is incremented by 1 (step S137), and the process returns to step S132.
The processing of steps S132 to S136 is performed for the next item. When m = n (step S1)
36; Y), the write process ends, and the process returns to the routine shown in FIG.
