    摘要： An apparatus and a method for controlling a light source used for image reading according to a user activity are provided. The light source controller being coupled to a light source and configured to change the power of the light source from an OFF state to an ON state when a user activity signal having a first state is output, the user activity signal having the first state being assumed to be output when a user activity, other than an instruction to begin scanning, that is assumed to ultimately cause output of the image reading start signal has been performed on the image reading apparatus.
