Abstract
An apparatus includes a distance sensor, an image sensor, one or more processors, and memory. The memory stores one or more programs configured for execution by the one or more processors. The apparatus measures a baseline depth. The apparatus measures a first depth subsequent to measuring the baseline depth. The apparatus determines that the first depth is different from the baseline depth. In response to the determination, the apparatus activates a read cycle. Subsequent to activating the read cycle, the apparatus measures a second depth. The apparatus detects that the second depth is within a threshold range of the baseline depth. In response to the detection, the apparatus deactivates the read cycle.
Claims20
A method performed by an apparatus having a distance sensor, an image sensor, one or more processors, and memory, the method comprising:
- measuring a baseline depth representing a distance from the apparatus to a surface, the baseline depth is used to determine activation and deactivation of a read cycle of the apparatus;
- subsequent to measuring the baseline depth, measuring a first depth;
- determining whether the first depth is different from the baseline depth;
- in response to the determination that the first depth is different from the base line depth, activating a read cycle to capture an image, the first depth representing a distance from the apparatus to an object;
- subsequent to activating the read cycle, measuring a second depth;
- detecting whether the second depth is within a threshold range of the baseline depth;
- and
- in response to the detection that the second depth is within a threshold range of the baseline depth, deactivating the read cycle to stop image capture and image processing, the second depth representing a new distance from the apparatus to the surface.
An apparatus, comprising:
- a distance sensor;
- an image sensor;
- one or more processors;
- and
- memory coupled to the one or more processors, the memory storing one or more programs configured for execution by the one or more processors, the one or more programs including instructions for:
- measuring a baseline depth representing a distance from the apparatus to a surface, the baseline depth is used to determine activation and deactivation of a read cycle of the apparatus;
- subsequent to measuring the baseline depth, measuring a first depth;
- determining whether the first depth is different from the baseline depth;
- in response to the determination that the first depth is different from the base line depth, activating a read cycle to capture an image, the first depth representing a distance from the apparatus to an object;
- subsequent to activating the read cycle, measuring a second depth;
- detecting whether the second depth is within a threshold range of the baseline depth;
- and
- in response to the detection that the second depth is within a threshold range of the baseline depth, deactivating the read cycle to stop image capture and image processing, the second depth representing a new distance from the apparatus to the surface.
