Abstract
An active graphical control that automatically maintains a minimum level of contrast between the control and the background against which the control is being displayed is disclosed.
Claims26
An active graphical control comprising:
- at least one graphical element with at least a first pixel the pixel having a first color;
- a means for detecting at least one color in a background where the at least one color is near the first pixel;
- the at least one pixel configured to change to at least a second color when the contrast between the first color and the at least one color in the background is below a predetermined level.
An active graphical control comprising:
- a first graphical element with at least a first color and having an outer perimeter;
- a means for detecting a at least one background color where the at least one background color is adjacent to the outer perimeter;
- the first graphical element configured to change the at least one background color to a second background color when the contrast between the at least one background color and the first color is below a predetermined level.
An active graphical control comprising:
- a first graphical element with at least a first color and having at least one transparent component;
- a means for detecting at least one background color where the at least one background color is underneath the transparent component;
- the first graphical element configured to change the at least one background color to a different background color when the contrast between the first color and the at least one background color is below a predetermined level.
A method for displaying an active graphical control comprising:
- (a) detecting at least one background color near the active graphical control;
- (b) determining a contrast between the at least one background color and at least one color in the graphical control;
- (c) changing the at least one color in the graphical control to at least a second color when the contrast between the first color and the at least one background color is below a predetermined level.
A method for displaying an active graphical control comprising:
- (a) displaying a graphical control against a background;
- (b) determining at least one contrast level between the background and the graphical control;
- (c) changing the visual appearance of the graphical control when the at least one contrast level is below a predetermined amount.
A method for displaying an active graphical control comprising:
- (a) detecting at least one background color adjacent to the active graphical control;
- (b) determining a contrast between the at least one background color and at least one color in the active graphical control;
- (c) changing the at least one background color adjacent to the active graphical control to a second color when the contrast between the first color and the at least one background color is below a predetermined level.
A program configured to display an active graphical control comprising:
- a first graphical element with at least a first color and having an outer perimeter;
- at least one background color where the at least one background color is adjacent to the outer perimeter;
- the first graphical element configured to change to at least a second color when the contrast between the first color and the at least one background color is below a predetermined level.
A program configured to display an active graphical control comprising:
- a first graphical element with at least a first color and having an outer perimeter;
- at least one background color where the at least one background color is adjacent to the outer perimeter;
- the first graphical element configured to change the at least one background color to a second background color when the contrast between the first color and the at least one background color is below a predetermined level.
A program configured to display an active graphical control comprising:
- a first graphical element with at least a first color and having at least one transparent component;
- at least one background color where the at least one background color is underneath the transparent component;
- the first graphical element configured to change the at least one background color to a second background color when the contrast between the first color and the at least one background color is below a predetermined level.
A portable digital device comprising:
- a display area;
- a microprocessor configured to display at least one background on the display area, the micro processor also configured to display at least one graphical control on the display area over the background, the graphical control having at least one color, where at least one color of the displayed graphical control is chosen to create a predetermined level of contrast between the background and the displayed graphical control.
A digital camera comprising:
- a display area;
- a microprocessor configured to display at least one image on the display area, the micro processor also configured to display at least one graphical control on the display area over the displayed image, where at least one color of the displayed graphical control is chosen to create a predetermined level of contrast between the images and the displayed graphical control.
