Sensor control apparatus, sensor control method, and program
A sensor control apparatus includes a readout control circuit and a region setting circuit. The readout control circuit controls an event-driven vision sensor including a sensor array that includes sensors that generate event signals when a change in incident light intensity is detected, in such a manner that the event signals are read out at a first frequency in a first region on the sensor array and that the event signals are read out at a second frequency higher than the first frequency in a second region on the sensor array. The region setting circuit changes at least part of the first region to the second region on the basis of the number of first event signals acquired by the readout in the first region within a given period of time or changes at least part of the second region to the first region on the basis of the number of second event signals acquired by the readout in the second region within the given period of time.

Imaging module and reader for, and method of, reading targets by image capture with a substantially constant resolution over an extended range of working distances
Targets are read by image capture with a substantially constant resolution over an extended range of working distances. Return light returning from a far-out target located at a far-out working distance is sensed by an array of pixels over a relatively narrow field of view, and over a relatively wide field of view when a close-in target is located at a close-in working distance. A controller processes the sensed return light from the far-out target only from a set of the pixels located in a central region of the array. For the close-in target, the controller groups all the pixels into bins, each bin having a plurality of the pixels, and processes the sensed return light from the close-in target from each of the bins.

IMAGING DEVICE AND CONTROL METHOD OF IMAGING ELEMENT
Power consumption of an imaging element which outputs only a region of interest (ROI) at high resolution is reduced. In a two-dimensional pixel array in which pixel rows arranged in a predetermined direction are arranged in a direction perpendicular to the predetermined direction, the imaging element performs imaging at high resolution for a first pixel row including a predetermined region and performs imaging at low resolution for a second pixel row other than this. The first image processing unit generates an image of a predetermined region on the basis of an imaging signal of the first pixel row. A pixel adding unit performs an adding process between pixels on the imaging signal of the first pixel row to make resolution the same as resolution of the imaging signal of the second pixel row. The second image processing unit generates an image of an entire region on the basis of the imaging signal of the second pixel row and the imaging signal of the first pixel row subjected to the adding process.
