Patent ID: 7508989

Claim:
An image processing method for converting compressed moving image data into moving image data made of a plurality of still images subjected to decoding processing and different in resolution from those before compression, the compressed moving image data including a first kind of image data and a second kind of image data which requires a larger calculation amount than the first kind of image data during decoding processing, the image processing method comprising: using a computer to perform the following: a decoding processing step of applying decoding processing to the first kind of image data and the second kind of image data; a first resolution conversion processing step of applying first resolution conversion processing to the first kind of image data subjected to decoding processing; a parameter acquisition step of acquiring a parameter for resolution conversion of the second kind of image data subjected to decoding processing, on the basis of a result of the first resolution conversion processing; and a second resolution conversion processing step of applying second resolution conversion processing to the second kind of image data subjected to decoding processing by using the acquired parameter.
