How to import photos from a digital camera using USB OTG?

I have some simple digital camera for my kids with only internal memory. I do have some windows software for it to import the photos. The windows software looks a bit outdated, but it works. When I connected it on an Ubuntu machine to read the USB ID ("ID 0979:0227 Jeilin Technology Corp., Ltd JL2005B/C/D Toy Camera") it worked instantly. The memory was mounted as a drive, I could see the photos and copy them! But when I go on holiday I will have neither a Windows PC nor an Ubuntu machine nearby. I will only have my Samsung Galaxy Note 10.1, which supports USB OTG. When I connect the camera via the USB OTG connector, the camera gives a bleep and on my tablet I see a message "USB connector attached". But I don't see a mounted drive (which I do see when I connect a simple USB memory stick). Is there some kind of app to import the photos from a digital camera? Regards,
