Abstract
An image signal processing apparatus includes: circuitry including: a mode setting circuitry configured to change a mode to one of a first mode and a second mode; a dividing circuitry configured to divide an input image signal into a base component signal and a detail component signal when the mode setting circuitry sets the first mode; a first tone compressing circuitry configured to perform a tone compression process on the base component signal to generate a compressed base component signal; a synthesizing circuitry configured to generate a synthetic image signal based on the detail component signal and the compressed base component signal; and a second tone compressing circuitry configured to perform a tone compression process such that tone of the input image signal becomes approximately equal to tone of the compressed base component signal when the mode setting circuitry sets a second mode.
