Image Capture Function
This function is used to capture image data and save it as a JPEG file. Using the function together
with the JPEG Library, the captured image data is output as image data in either 2-gray scale or
256-gray scale. The captured image data can also be output in low resolution by reducing its size.
The following table shows the reductions and sizes.
