An audio information processing apparatus for processing input audio information is adapted to input an audio signal composed of front area audio information that should be input to a front speaker and rear area audio information that should be input to a plurality of speakers. A mixer is adapted to mix the rear area audio information in accordance with an instruction from an instruction circuit.

Audio information processing apparatus and audio information processing method

There are provided an image processing apparatus and its method, in which a first image signal and a second image signal whose resolution is higher than that of the first image signal is selectively inputted, a low frequency component and a high frequency component are separated from the second image signal, the first image signal or an image signal of the separated low frequency component is encoded, and an image signal of the separated high frequency component is encoded.

Image processing apparatus and method

There is disclosed an image pickup apparatus which outputs moving image information, obtained with an image pickup device of progressive scanning type, as video signals of two channels, compresses the amount of information of the video signals of the two channels with compressing units of two channels, and transmits the compressed video signals of two channels to a peripheral device in the compressed state.

Image pickup apparatus

The amount of information in input digital image data is compressed at a first compression ratio and at a second compression ratio which is lower than the first compression ratio and recorded. When a still image is recorded, a still image having a high resolution can be recorded by compressing the digital image data at the second compression ratio and recording it.

Recording apparatus for compressing and recording moving and still images

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.
