A moving image processing apparatus can perform a zoom process for each frame image of moving image data in an digital zoom section. An image quality determining section determines an image quality of a frame image obtained through the zoom process in reproduction, when this zoom process is performed, and passes quality information representing its determined result to an MPEG CODEC. The MPEG CODEC encodes the moving image data processed in the digital zoom section and a noise reduction section, and stores the image data, and the quality information associated with each frame in a storage medium. In this manner, when the reproduction object data is processed to have some effect on the quality in reproduction, the data can be provided with the information regarding the quality in reproduction.
