Definitions
- the present disclosure provides an image processing method, the method comprising: acquiring a YUV image; acquiring a low-frequency signal of an input signal of a Y channel in the YUV image; signal, calculate the high-frequency signal; perform curve stretching on the input signal and the low-frequency signal respectively to obtain the first signal and the second signal; calculate the third signal according to the high-frequency signal and the second signal; and calculating an output signal based on the first signal and the third signal.
- the low-frequency signal is acquired by performing low-pass filtering on the input signal.
- the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into contact coordinates, and then sends it to the touch controller.
- the touch-sensitive surface 431 may be implemented using resistive, capacitive, infrared, and surface acoustic wave types.
- the input unit 430 may also include other input devices 432 .
- other input devices 432 may include, but are not limited to, one or more of physical keyboards, function keys (such as volume control keys, switch keys, etc.), trackballs, mice, joysticks, and the like.

Abstract
La présente invention concerne un procédé et un appareil de traitement d'images, un dispositif électronique et un support de stockage. Le procédé comprend les étapes consistant à : effectuer un étirement de courbe sur un signal d'entrée et sur un signal basse fréquence du signal d'entrée, respectivement, de manière à obtenir un premier signal et un deuxième signal ; calculer un troisième signal en fonction d'un signal haute fréquence du signal d'entrée et du deuxième signal ; lorsque la pente d'une courbe étirée est supérieure à 1, c'est-à-dire lorsqu'une plage dynamique d'une vidéo d'images est augmentée, utiliser le premier signal en tant que signal de sortie ; et lorsque la pente de la courbe étirée est inférieure ou égale à 1, c'est-à-dire lorsque la plage dynamique de la vidéo d'images est comprimée, utiliser le troisième signal en tant que signal de sortie.
