| 20210033470 | SEQUENTIAL BEAM SPLITTING IN A RADIATION SENSING APPARATUS - Systems, methods, and apparatuses for providing electromagnetic radiation sensing using sequential beam splitting. The apparatuses can include a micro-mirror chip having a plurality of light reflecting surfaces, an image sensor having an imaging surface, and a beamsplitter unit located between the micro-mirror chip and the image sensor. The beamsplitter unit includes a plurality of beamsplitters aligned along a horizontal axis that is parallel to the micro-mirror chip and the imaging surface. The beamsplitters implement the sequential beam splitting. Because of the structure of the beamsplitter unit, the height of the arrangement of the micro-mirror chip, the beamsplitter unit, and the image sensor is reduced such that the arrangement can fit within a mobile device. Within a mobile device, the apparatuses can be utilized for human detection, fire detection, gas detection, temperature measurements, environmental monitoring, energy saving, behavior analysis, surveillance, information gathering and for human-machine interfaces. | 2021-02-04 |
| 20210033471 | IMAGE DISPLAY DEVICE AND IMAGE DISPLAY METHOD - An image display device generates a temperature information image indicating, by a numerical value, a temperature of each pixel contained in a predetermined area including a position on a thermal image specified by a user, and causes a display to display the temperature information image while a temperature of a pixel corresponding to the position specified is displayed at a center of the temperature information image. The image display device sets a temperature range that has a predetermined temperature width and a center which is a temperature of a pixel corresponding to a position the temperature information image specified by the user, updates the temperature-color conversion information based on the set temperature range, regenerates the thermal image and the temperature information image based on the temperature-color conversion information updated, and causes the display to display the regenerated thermal image and the regenerated temperature information image. | 2021-02-04 |
