Claim:
An electronic camera having a playback mode which outputs data stored in a recording medium via a first buffer memory, comprising: a setter for setting a transfer instruction including a file address, a buffer memory address and a data size in an instruction list; a transferer for transferring from said recording medium to said first buffer memory data complying with the transfer instruction set in said instruction list; a reader for reading the data stored in said first buffer memory by a transfer process of said transferer; a first detector for detecting a size of data which is not yet transferred by said transferer out of the data complying with the transfer instruction set in said instruction list; a second detector for detecting a size of data which is not yet read by said reader out of the data complying with the transfer instruction set in said instruction list; and a disabler for disabling said reader when a difference value which is acquired by subtracting the size detected by said first detector from the size detected by said second detector is below a threshold value.
