Abstract: Color is edited using a color representation including digital values B (brightness), e and f such that B=?{square root over (D2+E2+F2)}, e=E/B, f=F/B, where DEF is a linear color coordinate system. Alternatively, color is represented using digital values B, C (chroma) and H (hue), where cos C=D/B and tan H=E/F. Brightness can be changed without a color shift by changing the B coordinate and leaving unchanged the other coordinates e and f or C and H. Other features are also provided.

Abstract: An entertainment console is provided on a stroller, where the console securely holds a DVD player or other type of audio/video/media player. The console has a cavity that holds the DVD play. A release mechanism, such as a spring-biased release may be used to “pop” the DVD player out of the cavity. When the console is secured in the cavity, a hinged door can be closed over the DVD player to protect the DVD player. When the hinged door is opened, the DVD player screen can be opened as well for viewing. The DVD player screen is thus between the opened hinged door and the child. The console also has a sliding door or other protective element that slides over the DVD player controls when the DVD is in use.

Abstract: In a digital image having pixels pi (i=1,2, . . . ) and a brightness B(pi) at each pixel pi, the contrast editing is performed by replacing the brightness B(pi) with B*(pi)=Bavg1??(pi)×Bo?(pi), where ? is a positive constant other than 1, and Bavg is a weighted average of the B values in an image region R(pi) containing the pixel pi. The image can be a color image, with color represented using digital values B (brightness), e and f such that B=?{square root over (D2+E2+F2)}, e=E/B, f=F/B, where DEF is a linear color coordinate system. Alternatively, color can be represented using digital values B, C (chroma) and H (hue), where cos C=D/B and tan H=E/F. The contrast can be edited without a color shift (i.e. without changing the chromaticity coordinates) by changing the B coordinate and leaving unchanged the other coordinates e and f or C and H. Sharpness can be edited using the same techniques with a small region R(pi).
