Operating a touch screen control system according to a plurality of rule sets
First Claim
1. An electronic device comprising:
- a display screen configured for displaying images;
a host processing system;
a memory; and
control circuitry configured to operate a touch sensor for capacitively detecting user input in a sensing region of a touch sensor, said control circuitry comprising;
display control circuitry comprising;
a blended image generator for autonomously generating a blended image by blending a primary image held in said memory and a secondary image held in said memory in response to a detected user input, wherein said primary image is received from said host processing system; and
a display screen updater for autonomously updating said display screen with said blended image, wherein said display screen is updated at a higher rate when updated autonomously by said display screen updater than when directed by said host processing system, and wherein said autonomously updating said display screen by said display screen updater reduces processing of said host processing system; and
touch sensor control circuitry for operating said touch sensor and for direct communications with said display control circuitry.

Abstract
A touch screen control system comprising a memory and control circuitry is configured to communicate with a host processing system. The control circuitry comprises a blended image generator and a display screen updater, and operates a touch sensor for detecting user input in a sensing region of the touch sensor. The sensing region overlaps a display screen. In response to detection of user input in the sensing region, the blended image generator autonomously generates a blended image by blending primary image and secondary images held in the memory. The display screen updater autonomously updates the display screen with the blended image. The display screen is updated at a higher rate when updated autonomously by the display screen updater than when directed by the host processing system. The autonomous updating of the display screen by the display screen updater reduces processing of the host processing system.

4. A touch screen control system configured to communicate with a host processing system, said touch screen control system comprising:
-
a memory; and control circuitry configured to operate a touch sensor for capacitively detecting user input in a sensing region of said touch sensor, wherein said sensing region overlaps a display screen, said control circuitry comprising; a blended image generator for autonomously generating a blended image by blending image data held in said memory in response to a detection of a first type of user input in said sensing region and without requiring intervention from said host processing system following said detection of said first type of user input; and a display screen updater for autonomously updating said display screen with said blended image without requiring intervention from said host processing system following said detection of said first type of user input, wherein said display screen is updated autonomously by said display screen updater at an autonomous display image update rate in response to said detection of said first type of user input in said sensing region, and wherein said autonomous display image update rate is higher than an image data update rate at which said host processing system would update said image data in response to said first type of user input in said sensing region. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A method for autonomously updating a display screen, comprising
capacitively detecting user input in a sensing region of a touch sensor, wherein said sensing region overlaps a display screen of an electronic device; -
autonomously generating a blended image by blending image data held in memory of said electronic device, wherein said blended image is generated in response to said detection of said user input and without requiring intervention from a host processing system of said electronic device following said detection of said user input; and autonomously updating said display screen with said blended image without requiring intervention from said host processing system in response to said detection of said user input in said sensing region, wherein said display screen is updated autonomously at an autonomous display image update rate in response to said detection of said user input in said sensing region, and wherein said autonomous display image update rate is higher than an image data update rate at which said host processing system would update said image data in response to said user input in said sensing region. - View Dependent Claims (19, 20)
