Problems solved by technology

If the event occurs infrequently, or if the timing of the event is unknown or not easily predictable, the RGB camera may need to maintain continuous operation at a high frame rate, which may make the use of the RGB camera or sensor impractical due to the high power consumption rate actual
As a result, recording image data of such an event using traditional methods would require a lot of power

Abstract

An image sensor includes a plurality of pixels. The pixel is capable of detecting a change in the amount of light intensity, and the pixel is capable of detecting the amount of light intensity. In a first mode, the sensor outputs data from a first one or more of the pixels. In a second mode, the sensor outputs data from one or more second ones of the pixels. The processor selects at least one of the first mode and the second mode based on at least one of a processing result of the data output in the first mode and a processing result of the data output in the second mode.

Description

technical field [0001] The present disclosure relates to cameras with event-based sensor capabilities and image sensor capabilities, and to dynamic switching between event-based sensors and RGB sensors for low power applications. Background technique [0002] In the related art, RGB sensors are used to generate image data to capture details of a scene. RGB sensors provide imagery that can be used in many applications from security to sporting events. However, RGB sensors may require high power consumption rates, which makes the use of RGB sensors impractical or undesirable in many applications. For example, in some applications it may be desirable for the camera to record video and / or still image data related to the event. If the event occurs infrequently, or if the timing of the event is unknown or unpredictable, the RGB camera may need to maintain continuous operation at a high frame rate, which may make the use of the RGB camera or sensor impractical due to the high pow...
