Claim:
An image combining apparatus which generates, on the basis of a first image signal of an object obtained by a first exposure according to a first exposure amount and a second image signal of said object obtained by a second exposure according to a second exposure amount which is less than said first exposure amount, a combined image signal of said object, comprising: a comparer for comparing a brightness relating level of any one of said first image signal and said second image signal with a reference value; a first selector for selecting said first image signal when said brightness relating level is equal to or less than said reference value; a second selector for selecting said second image signal when said brightness relating level is larger than said reference value; a deviation degree detector for detecting a deviation degree of color of said object, the deviation degree of color relating to a hue distortion that occurs when a color level of a specific color is saturated; and a reducer for reducing said reference value on the basis of said deviation degree.
