To select a color tone adjusting mode in an electronic camera, a guide for adjusting the color tone is shown on a monitor, an operation signal from direction buttons is read, and it is judged from the read operation signal whether the direction buttons are operated. If the part film webs are stored as a plurality of part film webs on a common supply shaft, various problems can arise. and an implanting of oxygen ions so as to form an amorphous layer; and subjecting the silicon wafer to a heat-treating in a mixed gas atmosphere containing oxygen so as to form a buried oxide layer. The second communications unit cooperates with the first communications unit to establish a communications link between the first and second controllers while maintaining separability between the first and second printed circuit boards. The step of processing the thermal treatment and the step of forming the capacitor protective film are performed continuously in the same system without exposing to an ambient atmosphere. The sound processing engine applies the sound processing criteria to the first and second real channel inputs.
