Abstract
There is provided an auto detection system including a thermal detection device and a host. The host controls an indication device to indicate a prompt message or detection results according to a slope variation of voltage values or 2D distribution of temperature values detected by the thermal detection device, wherein the voltage values include the detected voltage of a single pixel or the sum of detected voltages of multiple pixels of a thermal sensor.

An auto detection system, comprising:
- a thermal detection device, having a field of view covering a pot on a stove, the thermal detection device comprising a thermopile sensor array configured to output a thermal frame having multiple object temperatures;
- and
- a host, configured to receive the multiple object temperatures, and control an indication device to remind a user to put ingredients in the pot upon identifying that at least one of the multiple object temperatures is larger than a heating threshold.
An auto detection system, comprising:
- a thermal detection device, having a field of view covering ingredients, the thermal detection device comprising a thermopile sensor array configured to output a thermal frame having multiple object temperatures;
- and
- a host, configured to receive the multiple object temperatures, and control an indication device to remind a user to turn over the ingredients upon identifying that uniformity of the multiple object temperatures is lower than a uniformity threshold.
