Data processing device and data copying method
View Patent ↗For use in copying data between a plurality of recording media, the present invention provides a data processing device adds up the amounts of data on a plurality of files recorded on a transmitting medium to thereby detect the total amount of copy data, displays an intermediate result of addition on a display unit while updating the result displayed during a process from the start of addition of the amounts of file data until the completion of addition and displays the final result of addition on the display unit upon the completion of addition. The user is unlikely to feel uneasy even when the detection of the total amount of copy data takes time.
1. A data processing device capable of copying data between a plurality of recording media and comprising
an arithmetic processor for adding up the amounts of data on a plurality of files recorded on a transmitting medium to thereby detect the total amount of copy data,
a display unit for displaying the total amount of copy data detected, and
a display controller for displaying an intermediate result of addition on the display unit while updating the result displayed during a process from the start of addition of the amounts of file data by the arithmetic processor until the completion of addition and displaying the final result of addition on the display unit upon the completion of addition
wherein updating and displaying the intermediate result a copy data total amount is displayed every time the amount of data in one file is added up in an initial stage of a detection procedure and as the detection procedure progresses the display updating process is thinned out as a function of at least one of time, file data amount, or number of files to gradually increase a display updating interval.
2. A data processing device according to claim 1 which further comprises a detector for detecting the data recordable capacity of a receiving medium and wherein the display controller displays on the display unit the detected data recordable capacity along with the total amount of copy data.
3. A data processing device according to claim 1 wherein the arithmetic processor starts to detect the total amount of copy data upon turning on a power source or a change of medium or in response to a copying command signal.
4. In copying data between a plurality of recording media, a data copying method comprising
executing a process for adding up the amounts of data on a plurality of files recorded on a transmitting medium to thereby detect the total amount of copy data,
displaying an intermediate result of addition on a display unit while updating the result displayed during a process from the start of addition of the amounts of file data until the completion of addition and
displaying the final result of addition on the display unit upon the completion of addition,
wherein when updating and displaying the intermediate result a copy data total amount is displayed every time the amount of data in one file is added up in an initial stage of a detection procedure and as the detection procedure progresses the display updating process is thinned out as a function of at least one of time, file data amount, or number of files to gradually increase a display update interval.
5. A data copying method according to claim 4 wherein the detection of the total amount of copy data is started upon turning on a power source or a change of medium or in response to a copying command signal.
