Smart trigger logic for focal plane arrays
| DWPI Title: Electronic device i.e. computing system, has memory persistently storing light intensity values for pixels identified as triggered or neighbor pixels, and transmitter transmitting stored values for triggered and neighbor pixels to receiver |
| Abstract: An electronic device includes a memory configured to receive data representing light intensity values from pixels in a focal plane array and a processor that analyzes the received data to determine which light values correspond to triggered pixels, where the triggered pixels are those pixels that meet a predefined set of criteria, and determines, for each triggered pixel, a set of neighbor pixels for which light intensity values are to be stored. The electronic device also includes a buffer that temporarily stores light intensity values for at least one previously processed row of pixels, so that when a triggered pixel is identified in a current row, light intensity values for the neighbor pixels in the previously processed row and for the triggered pixel are persistently stored, as well as a data transmitter that transmits the persistently stored light intensity values for the triggered and neighbor pixels to a data receiver. |
| Use: Electronic device i.e. computing system (claimed). Uses include but are not limited to personal computer (PC), desktop computer, laptop computer, message processor, hand-held device, multi-processor system, microprocessor-based or programmable consumer electronics, network PC, minicomputer, mainframe computer and mobile telephone. |
| Advantage: The device includes the memory that persistently stores the light intensity values for pixels identified as triggered or neighbor pixels, and the data transmitter that transmits the persistently stored light intensity values for the triggered and neighbor pixels to the data receiver, thus efficiently collecting and transmitting focal plane array data in a simple manner when transmission bandwidths are limited. |
| Novelty: The device (100) has a buffer (120) that temporarily stores light intensity values for previously processed row of pixels when a triggered pixel (116) is identified in a current row, light intensity values for neighbor pixels (117) in the previously processed row and for the triggered pixel are persistently stored. A memory (110) persistently stores the light intensity values for pixels identified as triggered or neighbor pixels. A data transmitter (125) transmits the persistently stored light intensity values for the triggered and neighbor pixels to a data receiver (130). |
