Application processor, electronic device and operation method thereof

An electronic device is disclosed, which includes: a display; a first camera module having a first field of view (FoV) and generating first image data; a second camera module having a second FoV that is less than the first FoV and generating second image data; and an application processor configured to obtain zoom information including a zoom ratio and a region of interest (ROI) determined based on a user's input, to generate converted image data by scaling an image area corresponding to the ROI with respect to image data corresponding to the zoom ratio from among the first image data and the second image data, and to control the display to display the converted image data. 公开了一种电子设备，包括：显示器；第一相机模块，具有第一视场(FoV)并生成第一图像数据；第二相机模块，具有小于第一FoV的第二FoV并生成第二图像数据；应用处理器，被配置为获得包括基于用户的输入确定的变焦比和感兴趣区域(ROI)的变焦信息，通过相对于来自第一图像数据和第二图像数据当中与变焦比相对应的图像数据缩放与ROI相对应的图像区域来生成转换的图像数据，以及控制显示器显示转换的图像数据。
