1. An image processing apparatus comprising:
at least one memory that stores instructions; and
at least one processor that executes the instructions to:
perform character recognition for first image data to obtain a first plurality of numerical values, including first amounts about first items and a first total amount about the first items;
learn a rounding processing method on a basis of a difference between the first total amount and a calculation result obtained from a calculation based on the first amounts; and
perform character recognition for second image data to obtain a second plurality of numerical values, including second amounts about second items and a second total amount about the second items; and
determine reliability of the character recognition performed for the second image data from a calculation based on the second amounts about the second items and the learned rounding processing method.
