A system includes a processor, a light source controlled by the processor and configured to emit a light, and an event based vision sensor controlled by the processor. The sensor includes a plurality of pixels. At least one of the plurality of pixels includes a photosensor configured to detect incident light and first circuitry configured to output a first signal based on an output from the photosensor. The first signal indicates a change of amount of incident light. The sensor includes a comparator configured to output a comparison result based on the first signal and at least one of a first reference voltage and a second reference voltage. The processor is configured to apply one of the first reference voltage and the second reference voltage to the comparator selectively based on an operation of the light source.

A cutting insert includes first and second polygonal surfaces and a plurality of side surfaces. A corner edge that has a corner rake surface on the first polygonal surface is formed at a first corner portion, and a main cutting edge is formed from the corner edge to a second corner portion. The main cutting edge includes, at least on a corner edge side, a rake angle gradual increase region where a rake angle of a main rake surface gradually increases to a positive angle side as going from a first end portion of the corner edge toward a second corner portion side.

A surface emission laser driving method according to an embodiment of the present technology includes the following two steps. (A) Generating drive pulses to be sequentially outputted to, out of a plurality of surface emission lasers disposed on a same substrate, each of the surface emission lasers selected as light-emission targets, on the basis of the number of surface emission lasers selected as the light-emission targets and a monitoring temperature that is immediately prior to light emission of each of the surface emission lasers selected as the light-emission targets. (B) Outputting the generated drive pulses to each of the surface emission lasers selected as the light-emission targets.

A main circuit includes a switching element, and converts electric power input to the main circuit and supplies a result of the conversion to a load. The controller switches a control scheme of the main circuit from a first control scheme to a second control scheme at a first time point when the output value starts to vary and switches the control scheme of the main circuit from the second control scheme to the first control scheme at a second time point when a determination is made that switching of a variation direction of the output value will occur on the basis of a detection value of the detector.

Exposure with sufficient optical energy is enabled while avoiding temperature rise of laser light emitting elements. Therefore, a light source device includes the plurality of laser light emitting elements and a drive unit. The drive unit drives each of the laser light emitting elements to perform a plurality of light emissions in one frame period in an image sensor that receives and captures light emitted from the plurality of laser light emitting elements and reflected by a subject.

Light source device, image sensor, and sensing module

The present disclosure relates to a solid-state image pickup element, an image pickup module and electronic equipment configured to avoid large scaling of an image pickup element caused by an improvement in functions thereof. The solid-state image pickup element is configured with a lamination of an image sensor substrate on which a plurality of pixels is arranged on a surface of a sensor, and a signal processing substrate in which signal processing of an image signal output from the image sensor substrate is executed. The signal processing substrate has an electronic blur correction processing unit, a first connection unit that connects with an optical blur correction processing unit, and a second connection unit that connects with a gyro sensor which detects a blur generated in an image. At least a part of signals passed between the gyro sensor and the optical blur correction processing unit passes through the signal processing substrate.
