RISSNet: Retain low‐light image details and improve the structural similarity net
IET Image Processing, Volume 16, Issue 7, Page 1793-1806, 29 May 2022., 2022 Abstract Images taken under low light conditions cause people's sensory vision to fall into blind areas, and the essential properties of objects are hidden in the dark. There are many excellent algorithms that can adjust the brightness of high and low light region, but they still have room for improvement in realizing the function of denoising and ...

Advanced optical methods for safe image reproduction on automotive displays
Journal of the Society for Information Display, Volume 30, Issue 1, Page 33-53, January 2022., 2022 Automotive Camera Monitor Systems should fulfil highest safety levels but today only digital data are supervised. We introduce “light‐to‐light” safeguarding by optical supervision of the display. Three different methods have been successfully evaluated: Photodiodes mounted to the display and a camera to capture the display content.

Local Dimming Algorithm of Automotive LCD Instrument Based on Otsu and Maximum Entropy
Journal of Nanomaterials, Volume 2022, Issue 1, 2022., 2022 In order to reasonably reduce the energy consumption of automotive LCD instrument and improve the display quality, a new local dimming algorithm is proposed in this paper. Firstly, the gray image of the input image is obtained by using the maximum principle, and then, the LED backlight brightness value is obtained by using Otsu method and maximum ...

Edge-lit LCD backlight unit for 2D local dimming
Optics Express, 2018 Local dimming technology has been highly desired for integration with liquid crystal displays (LCDs) in order to improve their contrast ratios (CRs) as well as to overcome power efficiency bottlenecks. In this paper, we propose and demonstrate a slim (~1 mm) edge-lit LCD backlight unit (BLU) capable of 2D local dimming.
