Abstract: An electronic device includes at least one sensor, memory storing one or more instructions, a display including a first panel and a second panel, the first panel and the second panel being foldable relative to each other about a folding axis, and one or more processors. The electronic device identifies a folding angle of the display by using the at least one sensor, adjusts an occurrence angle of a touch input event generated on the display when the display is in a folded state, identifies a stroke generated by the touch input event according to the adjusted occurrence angle of the touch input event, and displays the identified stroke on the display.

Abstract: The disclosure refers to the anti-blur infrared lens for the panoramic camera system, also known as Infrared Search and Track (IRST), using a 1280×1024 resolution sensor with a working F-number of 2. The lens operates in the mid-infrared wavelength range of 3-5 ?m, using a fast steering mirror (FSM) and a pair of lenses with extended polynomial surfaces to prevent image blur during integration time. The optical image captured by the lens always maintains sharpness during the change of rotation angle of the device by changing the angular position of FSM. The lens is capable of observing with wide angle-of-view and large rotation angle compensation ability, ensuring long detection distance.
