Abstract:
1. An image processing method for image data that uses image data and an exposure correction amount for the image data, said image processing method comprising: determining a brightness value correction amount of said image data by using a brightness value reference value, which is to become a criterion for an image quality adjustment regarding brightness value; determining a contrast correction amount of said image data by using a contrast reference value, which is to become a criterion for an image quality adjustment regarding contrast; modifying said brightness value correction amount to be smaller as said exposure correction amount is increased; in a case where said exposure correction amount is a positive correction amount, modifying said contrast correction amount to be smaller as said exposure correction amount is increased; adjusting a brightness value and a contrast of said image data by applying said modified brightness correction amount and contrast correction amount; and outputting an image based on said brightness value-adjusted and contrast-adjusted image data.
