Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
93 words
An environment-compliant image display system which
corrects an image based on environmental information
expressing a visual environment in an area in which the
image is displayed, and displays the image, the
environment-compliant image display system comprising: means for storing brightness correction information
for correcting brightness of the image, based on the
environmental information, and color correction information
for correcting color of the image, based on the
environmental information; and correction means for correcting image information for
displaying the image, based on the environmental
information, the brightness correction information, and the
color correction information.
Claim 2
Dependent Claim
31 words
The environment-compliant image display system as
defined by claim 1, wherein the brightness correction information
comprises a one-dimensional look-up table, and wherein the color correction information comprises a
three-dimensional look-up table.
Claim 3
Dependent Claim
50 words
The environment-compliant image display system as
defined by claim 2, wherein the one-dimensional look-up table comprises
at least one of a gamma table and a color balance table,
and wherein the three-dimensional look-up table comprises
at least one of a color gamut correction table and a color
temperature correction table.
Claim 4
Dependent Claim
47 words
The environment-compliant image display system as
defined by any one of claims 1 to 3, wherein the correction means comprises means for
collecting a plurality of types of environmental
information that is input thereto all together, and
corrects the image information based on the collected
environmental information.
Claim 5
Dependent Claim
39 words
The environment-compliant image display system as
defined by any one of claims 1 to 4, wherein the correction means modifies a predetermined
correction coefficient that is used in a correction of the
image information, based on the environmental information.
Claim 6
Dependent Claim
44 words
The environment-compliant image display system as
defined by any one of claims 1 to 5, further comprising: visual environment detection means for measuring at
least one of the color value, gamma, and color temperature
of an image that is displayed in the image-displayed area.
Claim 7
Dependent Claim
25 words
The environment-compliant image display system as
defined by any one of claims 1 to 6, wherein the image-displayed area is an area on a
screen.
Claim 8
Dependent Claim
44 words
The environment-compliant image display system as
defined by claim 7, further comprising: means for displaying an image that guides to input a
type of the screen; and means for inputting the input type of the screen as
at least part of the environmental information.
Claim 9
Dependent Claim
106 words
An information storage medium including a program
which corrects an image based on environmental information
expressing a visual environment in an area in which the
image is displayed, and displays the image, the information
storage medium comprising a program for a computer to
realize: means for a predetermined storage area to store
brightness correction information for correcting brightness
of the image, based on the environmental information, and
color correction information for correcting color of the
image, based on the environmental information; and correction means for correcting image information for
displaying the image, based on the environmental
information, the brightness correction information, and the
color correction information.
Claim 10
Dependent Claim
30 words
The information storage medium as defined by claim 9, wherein the brightness correction information
comprises a one-dimensional look-up table, and wherein the color correction information comprises a
three-dimensional look-up table.
Claim 11
Dependent Claim
49 words
The information storage medium as defined by claim 10, wherein the one-dimensional look-up table comprises
at least one of a gamma table and a color balance table,
and wherein the three-dimensional look-up table comprises
at least one of a color gamut correction table and a color
temperature correction table.
Claim 12
Dependent Claim
46 words
The information storage medium as defined by any one
of claims 9 to 11, wherein the correction means comprises means for
collecting a plurality of types of environmental
information that is input thereto all together, and
corrects the image information based on the collected
environmental information.
Claim 13
Dependent Claim
38 words
The information storage medium as defined by any one
of claims 9 to 12, wherein the correction means modifies a predetermined
correction coefficient that is used in a correction of the
image information, based on the environmental information.
Claim 14
Dependent Claim
48 words
The information storage medium as defined by any one
of claims 9 to 13, wherein the environmental information is information
from visual environment detection means for measuring at
least one of the color value, gamma, and color temperature
of an image that is displayed in the image-displayed area.
Claim 15
Dependent Claim
24 words
The information storage medium as defined by any one
of claims 9 to 14, wherein the image-displayed area is an area on a
screen.
Claim 16
Dependent Claim
57 words
The information storage medium including a program as
defined by claim 15; for a computer to realize: means for a display means to display an image that
guides to input a type of the screen; and means for an input means to input the input type of
the screen as at least part of the environmental
information.
