摘要： The present application discloses a display optimization method. The method includes setting a light-emitting substrate including a first plurality of unit regions. Each unit region is associated with a luminance produced by one or more light-emitting diodes. The method further includes determining a sensitive area having a second plurality of unit regions in part of the light-emitting substrate in association with eyeball position of viewer relative to the light-emitting substrate and a non-sensitive area having a plurality of combined-regions in remaining part of the light-emitting substrate. Additionally, the method includes transferring local variables including information about the sensitive area and the combining factor k to a processor. Furthermore, the method includes operating the processor based on the local variables to individually control a first luminance of the one unit region in the sensitive area and to commonly control a second luminance of one combined-region in the non-sensitive area.

摘要： A gesture shaking recognition method includes acquiring two adjacent frames of gesture images of a gesture (S100), selecting a tracking point in each of the two adjacent frames of gesture images (S200), determining positional information of a maximum value pixel point in each of the two adjacent frames of gesture images based on the tracking point (S300), and determining whether gesture shaking occurs (S400) based on the positional information of the maximum value pixel point in each of the two adjacent frames of gesture images and positional information of the tracking point in each of the two adjacent frames of gesture images. The tracking point in each of the two adjacent frames of gesture images may correspond to a same position on the gesture.
