Abstract

An image data processing method and apparatus are disclosed. The method comprises: loading preview image data input by image hardware; acquiring at least one of a feature image, current time information, and geographical location information; loading at least one of the feature image, the time information, and the geographical location information in the preview image data by using a canvas category; driving the image hardware to generate target image data; and embedding at least one of the feature image, the time information, and the geographical location information into the target image data according to a first coordination location in the preview image data by using the canvas category. The present disclosure implements automatic post processing of image data without the need to open a professional image processing tool to perform post processing, thereby greatly improving the convenience of operation, reducing the threshold of operation and time.
