SUMMARY OF THE INVENTION
In a self-timer mode, the self-timer lamp 11 operates for a

receives command signals, for example, a photographing
command signal, from a remote controller (not shown) and
relays the photographing command signal to the DCP 507 via
the micro-controller 512.

capacity, the DCP 507 indicates the lack of capacity of the
memory card and ends the photographing mode (S403). If the

portion INP via the micro-controller 512 (S607), the DCP 507
terminates the operation of the internal timer if the internal
timer is driving (S607a) because the internal timer must be
driven again in the preview mode (S2) or the setting mode
(S6) if the user generated a signal. The DCP 507 moves the
item selection bar ISB up or down (S608).
The DCP 507 sets white balance and parameters related to
the white balance according to a present photographing con

DCP 507 calculates the exposure by measuring incident lumi
items lM (see FIG. 11).
If a setting signal is input from the user input portion INP
via the micro-controller 512 (S609), the DCP 507 terminates
the operation of the internal timer if the internal timer is
