Data processing apparatus having an interface to which a recording medium having a communication function of transmitting stored data is attachable, data processing method for such data processing apparatus, and storage medium for storing instructions for such data processing apparatus

Abstract

In a case where a recording medium having a communication function is used for a digital still camera, noise may be generated and superposed on data to be recorded if data transmission is performed in imaging. On the other hand, in a case where data is transmitted in response to a user's request from an external apparatus, communication interruption degrades usability. The digital still camera obtains a product name of the recording medium from the recording medium so as to specify a transmission mode. If an automatic transmission mode for spontaneously performing data transmission is specified, data transmission is interrupted when imaging instruction is issued and furthermore the communication function of the recording medium may be disabled. On the other hand, if a manual transmission mode for performing data transmission in response to a request is specified, a communication state is maintained even if an imaging instruction is issued.
