Apparatuses and methods for processing video signals

A control method of an image processing apparatus comprising:

• receiving frame-rate-converted image signals derived from original video signals, the frame-rate-converted image signals having a lower frame rate than the original image signals, the frame-rate-converted image signals being derived from the original image signals using one of a plurality of different conversion methods, and the input unit receiving conversion information relating to a frame-rate conversion method employed to derive the frame-rate-converted image signals from the original video signals;
• subjecting the frame-rate-converted video signals received to an image-quality enhancement processing;
• and
• determining image-quality enhancement parameters for the conversion method indicated by the conversion information received and controls the image-quality enhancement processing to perform the image-quality enhancement processing of the frame-rate-converted video signals using the determined image-quality enhancement parameter.

An image processing apparatus comprising:

• a memory;
• a processor coupled to the memory which executes the following:
• inputting a converted image signal obtained from an original image signal, the converted image signal having a lower frame rate than the original image signal, the converted image signal being obtained from the original image signal using one of a plurality of different conversion methods;
• subjecting the converted image signal to a process for changing an image quality;
• detecting a conversion method of the converted image signal;
• determining a parameter for the process for changing the image quality in accordance with the detected conversion method;
• and
• controlling to perform the process for changing the image quality using the determined parameter.
