Rendering pipeline for color electrophoretic displays

A method for processing data on an electronic device, the method comprising:

• repetitively inputting successive rows of pixels of an input color image into a graphics pipeline module for sequentially processing the successive rows of pixels;
• processing the data for the successive rows of pixels of the input color image within the graphics pipeline module, by successively applying a plurality of different procedures to the data for the successive rows of pixels to produce modified data for use in displaying a modified color image, individual procedures of the different procedures modifying the data for the successive rows of pixels to compensate for limitations of a display on which the modified color image is to be displayed;
• and
• using the modified data produced by the graphics pipeline module for displaying the modified color image on the display.

An electronic device comprising:

• a display on which images are displayed and viewed using reflected light;
• a memory storing machine executable instructions;
• and
• one or more processors coupled to the memory and to the display, the one or more processors executing the machine executable instructions to implement a plurality of functions, including:
• repetitively inputting successive rows of pixels of an input color image into a graphics pipeline module for successively processing the successive rows of pixels;
• processing data for the successive rows of pixels of the input color image within the graphics pipeline module, by successively applying a plurality of different procedures defined by the machine executable instructions to the data for the successive rows of pixels to produce modified data for use in displaying a modified color image on the display, individual procedures of the different procedures modifying the data for the successive rows of pixels to compensate for limitations of the display on which the modified color image is to be displayed;
• and
• using the modified data produced by the graphics pipeline module when displaying the modified color image on the display.

One or more non-transitory, tangible computer-readable media storing computer executable instructions that, when executed, cause one or more processors of an electronic device having a display to perform a plurality of functions, including:

• repetitively inputting data for successive rows of pixels of an input color image into a graphics pipeline module for processing, producing modified data for use in displaying a modified color image;
• processing the data for individual rows of the successive rows of pixels of the input color image within the graphics pipeline module, by successively applying a plurality of different procedures to the individual rows, individual procedures of the different procedures modifying the data for the individual rows to compensate for limitations of a display on which the modified color image is to be displayed;
• and
• using the modified data for displaying the modified color image on the display.

An electronic device comprising:

• a display on which images are displayed and viewed using reflected light;
• a memory storing machine executable instructions;
• a graphics pipeline module;
• and
• one or more processors coupled to the memory and to the display, the one or more processors executing the machine executable instructions to implement a plurality of functions, including:
• processing data from an input color image using the graphics pipeline module, wherein the processing comprises sequentially applying a plurality of modifications to successive rows of pixels of the data from the input color image within the graphics pipeline module to produce modified data for use in displaying a modified color image on the display, and wherein the plurality of modifications to the successive rows of pixels of the data from the input color image include two or more of:
• enhancing a contrast of at least a portion of pixels comprising the data from the input color image;
• color downsampling the data from the input color image, so that a color resolution of the modified color image that is to be displayed is less than that of the input color image;
• increasing a color saturation of at least a portion of the pixels comprising the data from the input color image;
• reducing fringing in the data from the input color image;
• or
• using dithering for smoothing color transitions in the pixels comprising the data from the input color image;
• and
• using the modified data produced by the graphics pipeline for displaying the modified color image on the display.
