Abstract
There is provided a signal processing circuit that processes an event signal generated in an EVS. The signal processing circuit includes a memory for storing a program code and a processor for executing operation in accordance with the program code. The operation includes detecting the relation among at least either positions in a block obtained by dividing a detection region of the EVS regarding the event signals generated in the block or the clock times at which the event signals have been generated.
Claims20
A signal processing circuit comprising:
- a memory for storing a program code;
- and
- a processor for executing operations in accordance with the program code, wherein
- the operations include:
- processing one or more event signals generated in an event-based vision sensor;
- dividing a detection region of the event-based vision sensor into a plurality of blocks;
- distributing the one or more event signals generated in a block among the plurality of blocks to a block event buffer corresponding to the block;
- detecting, by a detector, a figure including a set of positions of the one or more event signals in the block event buffer;
- and
- outputting, from the detector, a block line parameter indicating the detected figure as a relation among the set of positions in the block event buffer.
A signal processing method comprising:
- distributing one or more event signals generated in a block, obtained by dividing a detection region of an event-based vision sensor, to a block event buffer corresponding to the block;
- detecting, by a detector, a figure including a set of positions of the one or more event signals in the block event buffer;
- and
- outputting, from the detector, a block line parameter indicating the detected figure as a relation among the positions in the block event buffer.
A non-transitory computer-readable medium storing computer-readable instructions that, when executed by one or more processors, cause the one or more processors to perform operations, comprising:
- distributing one or more event signals generated in a block, obtained by dividing a detection region of an event-based vision sensor, to a block event buffer corresponding to the block;
- detecting, by a detector, a figure including a set of positions of the one or more event signals in the block event buffer;
- and
- outputting, from the detector, a block line parameter indicating the detected figure as a relation among the positions in the block event buffer.
