Witryna1 cze 2016 · Sharpness is a combination of two factors: resolution and acutance. Resolution is straightforward and not subjective. It's just the size, in pixels, of the image file. All other factors equal, the higher the resolution of the image—the more pixels it has—the sharper it can be. Acutance is a little more complicated. Witryna16 cze 2024 · A thermal camera is made up of a lens, a thermal sensor, processing electronics, and a mechanical housing. The lens focuses infrared energy onto the sensor.
