| 1. An image processing device for performing signal processing on an inputted image signal based on parameters, the image
processing device comprising:
a parameter storing unit operable to store a plurality of parameters;
a parameter selecting unit operable to select one of the plurality of parameters according to the input image signal;
an image signal processing unit operable to perform the signal processing on the input image signal based on the parameter
selected by the parameter selecting unit; and
a dividing unit operable to divide a portion of the input image signal into a background screen and a portion of the input
image signal into at least one window area, the dividing depending on where on a display screen the input image signal is
displayed,
wherein the parameter selecting unit selects a specified parameter, from among the plurality of parameters, for the portion
of the input signal divided into the background screen, and selects one parameter, from among the plurality of the parameters,
for the portion of the input signal divided into the at least one window area on a window area basis according to the input
image signal, and
wherein the image signal processing unit performs the signal processing for the background screen and the at least one window
area on a window area basis, based on the parameters selected by the parameter selecting unit.
