Recall device

摘要

A small wearable recall device is provided to capture images triggered by a combination of a detection of a capture condition (e.g., changes in motion, temperature or light level) followed by a relatively stable period, as detected by an accelerometer. By triggering on the combination of a detected capture condition followed by a detected stability condition, a clearer image of the environment of an interesting event is expected to be captured. The small size of the recall device makes it possible to integrate it into common portable consumer products, such as MP3 players, purses, clothing, hats, backpacks, necklaces, collars, and other human-wearable products.

主权项

1. A portable recall device configured to be carried by a wearer comprising:
a camera configured to capture an image; at least one accelerometer configured to detect acceleration of the camera; a memory configured to store images; and a controller operably connected to the camera, wherein the controller is configured to:
detect a stable condition based on the at least one accelerometer;trigger the camera to capture the image based on the detected stable condition, wherein the image is stored in the memory;receive a sensor signal and, based on the sensor signal, detect occurrence of a capture condition and whether the capture condition occurred in temporal proximity of the capture of the image by the camera; andmaintain storage of the image in the memory if the capture condition occurred in temporal proximity of the capture of the image by the camera, and to delete the image from the memory if no capture condition is detect in temporal proximity of the capture.
