    • Disclosed is a method and a device, that includes a programmed data processor, to process image data. The method includes, for a plurality n of files each containing image data representing one of n images, selecting one file as a base file; selecting as a target file an image data file that is contextually-related file to the base file; comparing the target file and the base file to determine differences therebetween; and storing the target file as a reduced file that is a representation of differences between the image data of the target file and the image data of the base file. An image data file is selected as being contextually-related to the base file based on at least an image capture location, and/or on an image capture time, or based on a user input. Storing can be performed in a memory device that is a part of a wireless communications device, such as a cellular telephone or a personal communicator that includes a digital camera, such as a camera phone.
    • 公开了一种包括编程数据处理器以处理图像数据的方法和装置。 该方法包括:对于多个n个文件,每个文件包含表示n个图像之一的图像数据,选择一个文件作为基本文件; 将与文件相关的文件的图像数据文件选择为目标文件; 比较目标文件和基本文件,以确定其间的差异; 并且将目标文件存储为作为目标文件的图像数据与基本文件的图像数据之间的差异的表示的缩小文件。 基于至少图像捕获位置和/或图像捕获时间,或者基于用户输入,选择图像数据文件与基本文件上下文相关。 可以在作为无线通信设备的一部分的存储设备中执行存储,诸如蜂窝电话或包括诸如照相机电话的数码相机的个人通信器。
