Abstract
A scanning sensor system disclosed. The scanning sensor system induces a sensing element array and multiple analog-to-digital converters (ADCs). The sensing element array includes a group of pixels organized in a row and column configuration. During each read cycle, each pixel in an odd column of a row x is selectively connected to a corresponding one of the ADCs that is associated with the odd column pixels, while each pixel in an even column of a row x+(N/2)+1 is selectively connected to a corresponding one of ADCs that is associated with the even column pixels, wherein x is an integer and N is the total number of rows in the sensing element array.
Claims11
A scanning sensor system comprising:
- a sensing element array having a plurality of pixels organized in a row and column configuration;
- a plurality of switches;
- and
- a plurality of analog-to-digital converters (ADCs), wherein during each read cycle, each pixel in an odd column of a row x is selectively connected to a corresponding one of said plurality of ADCs in said odd column via one of said switches, which each pixel in an even column of a row x+(N/2)+1 is selectively connected to a corresponding one of said plurality of ADCs in said even column via one of said switches, wherein x is an integer and N is the total number of rows in said sensing element array.
The scanning sensory system of claim 4, further comprising a processor coupled to said ADCs.
A scanning sensory system comprising:
- a sensing element array having a plurality of pixels organized in a row and column configuration;
- a plurality of switches;
- and
- a plurality of analog-to-digital converters (ADCs), wherein during each read cycle, each pixel in a column 3x-2 of a row x is selectively connected to a corresponding one of said plurality of ADCs in said column 3x-2 via one of said switches, each pixel in column 3x-1 of a row x+(N/3)+1 is selectively connected to a corresponding one of said plurality of ADCs in said column 3x1 via one of said switches, and each pixel in a column 3x of a row x+(2N/3)+1 is selectively connected to a corresponding one of said plurality of ADCs in said column 3x via one of said switches, wherein x is an integer and N is the total number of rows in said sensing element array.
A method for improving frame rate in a scanning sensor system, said method comprising:
- providing a sensing element array having a plurality of pixels organized in a row and column configuration;
- providing a plurality of analog-to-digital converters (ADCs);
- during a read cycle, selectively connecting each pixel in an odd column of a row x to a corresponding one of said plurality of ADCs in said odd column, and concurrently selectively connecting each pixel in an even column of a row x+(N/2)+1 to a corresponding one of said plurality of ADCs in said even column, wherein x is an integer and N is the total number of rows in said sensing element array.
