Abstract
Abstract An image processing apparatus is constructed by a setting circuit for manually setting a first color processing parameter, a first color processing circuit for performing a first color process by using the first color processing parameter, a storing circuit for storing a second color processing parameter set in correspondence to the first color processing parameter as a reference value, and a second color processing circuit for performing a second color process different from the first color process by using the second color processing parameter, wherein in case of making the second color processing circuit function, the first color processing parameter is set to the reference value.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
100 words
An image processing apparatus comprising: setting means for manually setting a first color processing parameter; first color processing means for performing a first color process by using said first color processing parameter; storing means for storing a second color processing parameter set in correspondence to said first color processing parameter as a reference value; and second color processing means for performing a second color process different from said first color process by using said second color processing parameter, wherein in case of making said second color processing means function, said first color processing parameter is set to said reference value.
Claim 2
Dependent Claim
47 words
An apparatus according to claim 1, wherein on the basis of characteristics of an input unit or an output unit, said second color processing means executes said second color process by using said second color processing parameter so as to reproduce an image at a high fidelity.
Claim 3
Dependent Claim
99 words
An apparatus according to claim 1, further having resetting means for resetting said first color processing parameter corresponding to output means when an output image derived by said second color process cannot be satisfied, and wherein said first color processing means executes said first color process to the image data which was subjected to said second color process on the basis of said reset first color processing parameter, and said resetting process and the first color process based on said first color processing parameter set by said resetting means are repetitively executed until the output image can be satisfied.
Claim 4
Dependent Claim
27 words
An apparatus according to claim 1, wherein said storing means stores said second color processing parameter and said reference value so as to correspond to each other.
Claim 5
Dependent Claim
63 words
An image processing apparatus having first and second color matching modes for performing different color matching processes, comprising: selecting means for selecting the color matching mode on the basis of an instruction of a user; and setting means for setting a background color on a display screen to a predetermined color when said second color matching mode is selected by said selecting means.
Claim 6
Dependent Claim
34 words
An apparatus according to claim 5, further comprising: storing means for storing a profile according to said background color; and color matching processing means for performing the color matching process by using said profile.
Claim 7
Dependent Claim
32 words
An apparatus according to claim 5, wherein in said color matching process, a color adapting process according to said background color and an illumination light to illuminate said display screen is executed.
Claim 8
Dependent Claim
104 words
An image processing method comprising: a setting step of manually setting a first color processing parameter; a first color processing step of performing a first color process by using said first color processing parameter; a storing step of storing a second color processing parameter set in correspondence to said first color processing parameter as a reference value; and a second color processing step of performing a second color process different from said first color process by using said second color processing parameter, wherein in case of making said second color processing means function, said first color processing parameter is set to said reference value.
Claim 9
Dependent Claim
112 words
A recording medium to store programs to realize an image processing method comprising: a setting step of manually setting a first color processing parameter; a first color processing step of performing a first color process by using said first color processing parameter; a storing step of storing a second color processing parameter set in correspondence to said first color processing parameter as a reference value; and a second color processing step of performing a second color process different from said first color process by using said second color processing parameter, wherein in case of making said second color processing means function, said first color processing parameter is set to said reference value.
Claim 10
Dependent Claim
65 words
An image processing method having first and second color matching modes for performing different color matching processes, comprising: a selecting step of selecting the color matching mode on the basis of an instruction of a user; and a setting step of setting a background color on a display screen to a predetermined color when said second color matching mode is selected by said selecting step.
Claim 11
Dependent Claim
73 words
A recording medium to store programs to realize an image processing method having first and second color matching modes for performing different color matching processes, comprising: a selecting step of selecting the color matching mode on the basis of an instruction of a user; and a setting step of setting a background color on a display screen to a predetermined color when said second color matching mode is selected by said selecting step.
