Abstract: <P>PROBLEM TO BE SOLVED: To provide a digital still camera with a display capable of surely photographing an object and making a user shift to a photographing mode even when a reproduction mode is shifted to the photographing mode by the operation of a shutter button.   <P>SOLUTION: When half depression of a shutter is detected in the reproduction made (step S1), a CPU 9 discriminates a shift from the reproduction mode into the photographing mode (step S2) to give a switching instruction to a DSP 10. Specifically, the DSP switches display contents of a liquid crystal display screen from display contents for the reproduction mode into display contents of the photographing mode (step S3). Thus, the user can easily recognize the mode shift through half-depression of the shutter button and correct the mode by discriminating the mode shift if the shutter button 2 is depressed in mistake.  <P>COPYRIGHT: (C)2004,JPO
