Image processing apparatus, image processing method and image processing program

An image processing apparatus for performing correction for each frame group including a predetermined number of frames into which video data is divided, the image processing apparatus comprising:

• a processor;
• and
• a storage medium having computer program instructions stored thereon, wherein the computer program instructions, when executed by the processor, perform to:
• obtain a corrected frame group by correcting a second frame group using a feature quantity of a first frame group, which is a frame group previous to the second frame group in time and continuous with the second frame group in time, and a feature quantity of a third frame group, which is a frame group subsequent to the second frame group in time and continuous with the second frame group in time, and
• perform the correction so that subjective image quality based on a relationship between the corrected frame group and the first frame group and a relationship between the corrected frame group and the third frame group increases.

An image processing apparatus for performing correction for each partial data group including a predetermined number of partial data elements into which data are divided, the image processing apparatus comprising:

• a processor;
• and
• a storage medium having computer program instructions stored thereon, wherein the computer program instructions, when executed by the processor, perform to:
• obtain a corrected partial data group by correcting a second partial data group, which is a partial data group continuous with a first partial data group in time, using a feature quantity of the first partial data group, and
• perform the correction so that subjective image quality based on a relationship between the second partial data group and a partial data group subsequent to the second partial data group in time is increased and so that a predetermined classifier classifies that a partial data group in which the second partial data group is concatenated with the partial data group subsequent to the second partial data group in time is the same as a partial data group in which the corrected partial data group is concatenated with a corrected partial data group obtained by correcting the partial data group subsequent to the second partial data group in time.
