Information processing apparatus for helping intuitive and easy recognition of temperature of heat source

An information processing apparatus capturing and displaying a thermal image indicative of temperatures of a subject in colors, the information processing apparatus comprising:

• an infrared camera that captures the subject to generate the thermal image of the subject;
• a distance sensor that detects distances from the information processing apparatus to points on the subject;
• a display device that displays the thermal image;
• a storage device that stores a temperature-to-color conversion table indicative of correspondences between temperatures of the subject and pixel colors;
• and
• a control device that processes the thermal image based on the temperature-to-color conversion table, to display the processed thermal image on the display device,
• wherein the control device identifies a region of interest within a range of a predetermined distance from a reference point of the subject, based on the distances detected by the distance sensor,
• wherein the control device sets lower and upper limits of a temperature range based on temperatures of points within the region of interest,
• wherein the control device updates the temperature-to-color conversion table based on the lower and upper limits of the temperature range, and
• wherein the control device regenerates the thermal image based on the updated temperature-to-color conversion table, to display the regenerated thermal image on the display device.
