Abstract:
An image data processing apparatus having an editing machine for processing digital image data and transferring the image data between a plurality of memory cards in which digital image data is recorded and a plurality of external devices in which digital image data is recorded, said editing machine comprising:a plurality of holding parts for holding said memory cards;a plurality of connecting parts for respectively connecting the plurality of external devices to the editing machine;first data processing means for selectively reading the digital image data from said plurality of memory cards held by said plurality of holding parts, compressing the digital image data by a discrete cosine transform system or expanding the data by a reverse discrete cosine transform system, and transferring the data to said external devices connected to said plurality of connecting parts;second data processing means for selectively reading said digital image data from said external devices connected to said connecting parts, compressing the digital image data by the discrete cosine transform system or expanding the data by the reverse discrete cosine transform system, and transferring the data to said memory cards held in said holding parts; andthird data processing means for selectively reading the digital image data from said memory cards held in said holding parts, compressing the digital image data by the discrete cosine transform system or expanding the data by the reverse discrete cosine transform system, and transferring the data to the memory cards other than said memory cards from which the digital image data has been read out.
