Imaging Systems and Associated Methods for Power Management

A system comprising:

• an image sensor that acquires images within a first field-of-view;
• an illumination device configured to illuminate the first field-of-view at least one of before or during image acquisition by the image sensor;
• a depth sensor including a plurality of photosensitive cells that acquires distance information within a second field-of-view, the second field-of-view at least partially overlapping the first field-of-view;
• and
• at least one processor programmed to control an operation of the at least one processor, the image sensor, the illumination device, and the depth sensor based on a plurality of modes of operation, the plurality of modes of operation including a first mode of operation and a second mode of operation,
• the at least one processor is programmed to transition from the first mode of operation to the second mode of operation in response to satisfaction of a specified first criteria based on object information associated with the distance information output by the depth sensor for an object within the second field-of-view,
• at least one of image acquisition by the image sensor or illumination by the illumination device is deactivated in the first mode of operation and activated in the second mode of operation.

A non-transitory computer-readable medium storing instructions that are executable by one or more processors, wherein execution of the instructions by the one or more processors cause the one or more processors to perform a process comprising:

• operating an imaging system in a first mode of operation in which at least one component of the imaging system is deactivated, the imaging system including an image sensor having a first field-of-view and a depth sensor having a second field-of-view that at least partially overlaps the first field-of-view;
• detecting an object via the depth sensor of the imaging system within the second field-of-view, the depth sensor includes an array of photosensitive cells that acquires distance information for the object in the second field-of-view;
• determining, via a processor of the imaging system, object information associated with the object based on the distance information output of the depth sensor, the object information includes depth and position information of the object in three-dimensional space relative to a reference location;
• determining whether the object information associated with the object satisfies a specified first criteria;
• and
• transitioning the imaging system from the first mode of operation to a second mode of operation in response to the object information satisfying the specified first criteria, the at least one component being activated in the second mode of operation.
