DCF standard

This projector can only play back image files which comply with the DCF specifica- tion.The DCF specification imposes the following conditions. Image files or directo- ries which do not conform to these conditions cannot be recognised by the projector.

Limits on directory names

Directories must be created as sub-directories of the DCIM directory on the SD memory card.

BData which is contained within any directory other than the DCIM directory cannot be recognised.

Directory names must consist of three numerals (directory number) followed by five alphanumeric characters. (Example: 100abcde)

BThe three numerals must make up a number between 100 and 999, and the alphanumeric characters can be taken from the following set of 37 characters: 0123456789abcdefghijklmnopqrstuvwxyz_ (No distinction is made between upper-case and lower-case alphabetic characters. Double- byte characters cannot be used.)

Multiple directories using the same three-digit combination (directory number) cannot be created.

BFor example, if two directories exist named "100abcde" and "100fghij" respectively, the projector will not recognise them.

Directory sub-hierarchies are not supported.

BFor example, if a directory called "323fghij" is created as a sub-directory of the "102abcde" directory, the projector will not be able to recognise the sub-directory.

File names

File names must consist of four alphanumeric characters followed by four numerals (file number), followed by ".jpg". (Example: abcd0001.jpg)

BThe four numerals must make up a number between 0001 and 9999, and the alphanumeric characters can be taken from the following set of 37 characters: 0123456789abcdefghijklmnopqrstuvwxyz_ (No distinction is made between upper-case and lower-case alphabetic characters. Double- byte characters cannot be used.)

Multiple file names using the same four-digit combination (file number) cannot be created.

BFor example, if two files exist named "abcd0001.jpg" and "efgh0001.jpg" respectively, the projector cannot recognise them normally.

File format

BOnly JPEG image files which comply with the Exif 2.1 standard are recognised.
