1. A projector comprising:
a light source;
a light source control section adapted to control a luminance of light emitted from the light source;
an acquisition section adapted to obtain an image signal;
a projection section adapted to project image light obtained by modulating the light emitted from the light source based on the image signal obtained by the acquisition section; and
a correction section adapted to correct the image signal, when the luminance of the light emitted from the light source changes under control of the light source control section, so that a variation in an output luminance of the image light projected by the projection section is increased to a level greater than the variation in the luminance of the light emitted from the light source.
2. The projector according to claim 1, wherein
the correction section switches a correction amount of the image signal in accordance with one of the luminance of the light emitted from the light source, and time with which the luminance of the light emitted from the light source changes.
3. The projector according to claim 1, further comprising:
a storage section adapted to store a plurality of correspondence relationships between the image signal and a correction amount of the image signal,
wherein the correction section switches the correspondence relationships stored in the storage section in a stepwise manner, and corrects the image signal based on the correspondence relationship.
4. A control method comprising:
controlling a luminance of light emitted from a light source;
obtaining an image signal;
projecting image light obtained by modulating the light emitted from the light source based on the image signal obtained in the obtaining of an image signal; and
correcting the image signal, when the luminance of the light emitted from the light source changes due to control in the controlling of the light source, so that a variation in an output luminance of the image light projected in the projecting of image light is increased to a level greater than the variation in the luminance of the light emitted from the light source.
5. A projector comprising:
a light source;
a light source control section adapted to control a luminance of light emitted from the light source;
an input section to which image data is input;
a light modulation section adapted to modulate the light emitted from the light source based on the image data input to the input section;
a projection section adapted to project image light obtained by the modulation by the light modulation section; and
a correction section adapted to correct a voltage for driving the light modulation section, when the luminance of the light emitted from the light source changes under control of the light source control section, so that a variation in an output luminance of the image light projected by the projection section is increased to a level greater than the variation in the luminance of the light emitted from the light source.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method of controlling an Internet browser interface displayable by an Internet browser on a display of a computer, the Internet browser enabling a user of the computer and Internet browser to access and navigate the Internet and to receive and display on the computer display one or more web pages from one or more Internet sites, including the display of a web page from a predetermined Internet site, the Internet browser having at least one Internet browser toolbar having at least one toolbar button providing a predetermined functionality to the user of the computer and Internet browser, said method comprising the steps of:
(a) providing, at the predetermined Internet site, access to a program for controlling the Internet browser interface; and
(b) making available for downloading by the predetermined Internet site, a file for displaying of a user toolbar and a shopping assistant interface object as part of the Internet browser interface.
2. A method as recited by claim 1, wherein the file comprises an ActiveX control.
3. A method as recited by claim 1, wherein the file comprises a Plug-in.
4. A method as recited by claim 1, wherein the shopping assistant interface object is a toolbar button.
5. A method as recited by claim 1, wherein said file contains computer code for intercepting an Internet address for each Internet site to which the Internet browser is caused to navigate, determining if a web site to which the Internet browser is caused to navigate is a supported merchant web site, and if the web site is a supported merchant web site, automatically filling out a check-out web page of a supported merchant web site using a wallet and a supported merchant rules and mapping file.
6. A method as recited by claim 1, wherein said file contains computer code for adding a shopping assistant button and a toolbar of the Internet browser.
7. A method as recited by claim 1, wherein said file contains computer code for providing an indicator when the Internet browser is caused to navigate to a supported merchant web site.
8. A method as recited by claim 1, wherein said files contains computer code for determining if a web site to which the Internet browser is caused to navigate is a supported merchant web site by comparing a supported merchant data file with an Internet address for each Internet site to which the Internet browser is caused to navigate.
9. A system for controlling an Internet browser interface displayable by an Internet browser on a display of a computer, said system comprising:
a server, said server including a program accessible over the Internet by a user of the computer for controlling the Internet browser interface; and
a file downloadable by said server to the computer for controlling the Internet browser interface, wherein said downloadable file causes a user toolbar and a shopping assistant interface object to be added to the browser interface and to be displayed on the display of the computer as part of the Internet browser interface while the Internet browser is activated regardless of the Internet site to which the computer is connected via the Internet browser.
10. A system as recited by claim 9, wherein said shopping assistant interface object comprises an ActiveX control.
11. A system as recited by claim 9, wherein said shopping assistant interface object comprises a Plug-in.
12. A system as recited by claim 9, wherein said file contains computer code for intercepting an Internet address for each Internet site to which the Internet browser is caused to navigate, determining if a web site to which the Internet browser is caused to navigate is a supported merchant web site, and if the web site is a supported merchant web site, automatically filling out a check-out web page of a supported merchant web site using a wallet and a supported merchant rules and mapping file.
13. A system as recited by claim 9, wherein said file contains computer code for adding a shopping assistant button and a toolbar of the Internet browser.
14. A system as recited by claim 9, wherein said file contains computer code for providing an indicator when the Internet browser is caused to navigate to a supported merchant web site.
15. A system as recited by claim 9, wherein said files contains computer code for determining if a web site to which the Internet browser is caused to navigate is a supported merchant web site by comparing a supported merchant data file with an Internet address for each Internet site to which the Internet browser is caused to navigate.
