ABSTRACT:
There is provided an image processing apparatus which comprises an inputting part for inputting an image signal, an attenuating part for attenuating a predetermined frequency portion of the image signal inputted by the inputting part, and a controlling part for controlling an attenuation characteristic of the attenuating part for attenuating the predetermined frequency portion, in accordance with a compression ratio of the image signal inputted by the inputting part. There is also provided an image processing apparatus which comprises an inputting part for inputting an image signal, an enhancing part for enhancing a high frequency band of the image signal inputted by the inputting part, and a controlling part for controlling a high-frequency-band enhancement characteristic of the enhancing part in accordance with a compression ratio of the image signal inputted by the inputting part. There is also provided an image processing apparatus which comprises an inputting part for inputting an image signal, a discriminating part for making a discrimination as to a particular attribute of the image signal inputted by the inputting part, a generating part for generating an attribute signal indicating that the image signal inputted by the inputting part represents an image having the particular attribute, in accordance with an output of the discriminating part, and a combining part for combining an output of the generating part with the image signal.
