In actual fact the loss is mostly down to revised accounting after the financial scandal broke in October.
For the final quarter of 2012 the medical imaging division made an operating profit of 18bn yen while the rest of the company lost about 10 billion, which is about £82m or $129m and the camera division is probably only responsible for part of that.
