Abstract
Abstract A system and method for generating timing signals in an electronic imaging device includes a horizontal timing generator with a first programmable memory for storing a set of timing information and a vertical timing generator with a second programmable memory for providing a set of control information which is used to selectively generate the timing signals from the set of timing information in the first programmable memory.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
131 words
A system for generating timing signals for controlling a charge-coupled image sensor in an electronic device that captures image data, comprising: a horizontal timing generator coupled to said electronic device, said horizontal timing generator including, a first random access memory for storing a first set of timing information, and selector devices coupled to said first set of timing information to generate said timing signals by selecting locations in said first random access memory; a vertical timing generator coupled to said electronic device, said vertical timing generator including, a second random access memory for providing a second set of timing information to selectively generate said timing signals from said first set of timing information; and a configuration module device for programming said first random access memory and said second random access memory.
Claim 2
Independent Claim
131 words
A system for generating timing signals for controlling a charge-coupled image sensor in an electronic device that captures image data, comprising: a horizontal timing generator coupled to said electronic device, said horizontal timing generator including, a first random access memory for storing a first set of timing information, and selector devices coupled to said first set of timing information to generate said timing signals by selecting locations in said first random access memory; a vertical timing generator coupled to said electronic device, said vertical timing generator including, a second random access memory for providing a second set of timing information to selectively generate said timing signals from said first set of timing information; and a configuration module device for programming said first random access memory and said second random access memory.
Claim 3
Dependent Claim
24 words
The system of claim 1 wherein said vertical timing generator provides selector control signals which control said selector devices in said horizontal timing generator.
Claim 4
Dependent Claim
