Abstract: A display apparatus includes a driving controller, a data driver and a display panel. The driving controller is configured to determine an average load of a unit area based on an average grayscale value of the unit area and a pixel area ratio of the unit area, to determine a temperature diffusion load of the unit area based on average loads, temperature diffusion ratios and weight ratios of adjacent unit areas adjacent to the unit area and to compensate input image data based on the average load of the unit area and the temperature diffusion load of the unit area to generate a compensated data signal. The data driver is configured to convert the compensated data signal into a data voltage. The display panel is configured to display an image based on the data voltage.

Abstract: A safe landing point search device for searching for a safe landing point of an unmanned exploration device that lands on and explores a celestial body, includes a terrain map obtaining unit configured to obtain a terrain map, a contour line generating unit configured to generate contour lines based on a reference minimum height value and a height interval value by using the terrain map, a largest empty circle (LEC) searching unit configured to search for one or more LECs having a radius greater than or equal to a lower-limit radius in a contour line map including the contour lines, and a safe landing point outputting unit configured to output a safe landing point having a largest radius among the one or more LECs and transmit the safe landing point to the unmanned exploration device.
