Abstract: A method for operating an electronic device includes while a display is in low power mode, detecting based on data collected by a time of flight (ToF) sensor, a movable object within a field of view of the electronic device; in response to the detecting initiating a period of detection having a plurality of frames, the period of detection being a time period over which a distance value indicative of a distance between the movable object and the display is detected; for each of the plurality of frames, changing the distance value to reflect whether the movable object is moving near or further from the electronic device; detecting that the distance value after the period of detection is less than a threshold distance value indicative of the movable object approaching the display; if the distance value is less than the threshold distance value, waking up the display.

Abstract: At least one image of a moving object is acquired using an image acquisition device equipped with an automatic focussing system. A distance between the object and the device when the effective acquisition of the image occurs is estimated based on the estimated speed and on the period of time separating a time of actuation triggering the process for acquiring the at least one image from the time of acquisition of the said effective acquisition, and the taking into account of the said distance by the automatic focussing system.

Abstract: A flicker compensation method for images taken by an image sensor operating in rolling-shutter mode may include capturing a first image and capturing a second image offset in time from the first image by an integer or zero number of flicker periods, plus half a flicker period. The method may also include producing a compensated image based on an average of the first and second images.
Abstract translation: 用于以卷帘快门模式操作的图像传感器拍摄的图像的闪烁补偿方法可以包括捕获第一图像并从时间上从第一图像捕获第二图像偏移整数或零数量的闪烁周期，加上闪烁周期的一半 。 该方法还可以包括基于第一和第二图像的平均值产生补偿图像。
