    • A method and apparatus for controlling the display of a portable electronic device having a camera application, a viewfinder having at least two viewfinder resolutions, and a sensor array, is provided. When a zoom level of the camera application is 1×, a first image is generated by scaling a predetermined number of rows and columns of pixels of the sensor array to a first viewfinder resolution at a given frame rate. When the zoom level is greater than 1×, a region of interest of the predetermined number of rows and columns of pixels is cropped in accordance with the zoom level and a second image is generated by scaling the cropped region of interest to a second viewfinder resolution smaller than the first viewfinder resolution at a frame rate higher than the given frame rate.
    • 提供一种用于控制具有相机应用的便携式电子设备的显示方法和装置,具有至少两个取景器分辨率的取景器和传感器阵列。 当相机应用的缩放级别为1×时,通过以给定的帧速率将传感器阵列的预定数量的行和列的像素缩放为第一取景器分辨率来生成第一图像。 当缩放级别大于1×时,根据缩放级别裁剪预定行数和像素列的感兴趣区域,并且通过将感兴趣的裁剪区域缩放为第二取景器分辨率来生成第二图像 小于第一取景器分辨率,帧速率高于给定的帧速率。
