1. A digital still camera comprising:
- means for converting an optical image into a digital image signal;
transmitting means for transmitting an electromagnetic signal to a designated remote device accessible in accordance with a wireless telephone system, the electromagnetic signal containing a still image represented by the digital image signal;
storing means for storing the digital image signal input from the means for converting, the number of pixels of the still image in the storing means being greater than that of the still image signal represented by the electromagnetic signal;
means for receiving from said remote device an identification signal transmitted back in response to the designation of said remote device;
modifying means for modifying the electromagnetic signal into a digital image signal;
reducing means for reducing the number of pixels of the still image represented by said digital electronic image signal in the storing means prior to transmission and in response to the identification signal such that the remaining digital image signal has the same number of pixels as that of the still image signal represented by the electromagnetic signal; and
means for receiving the electromagnetic signal at the designated remote device.
