Abstract

An image information encoding device is provided, wherein an image analyzer calculates image analysis information on divided image information; an image analysis information holder temporarily stores the image analysis information therein; a weighting part performs a predetermined weighting process on each of the image analysis information and peripheral image analysis information temporarily stored in the image analysis information holder and outputs resultant information therefrom as final image analysis information; a coding parameter determination unit determines a coding parameter from the image analysis information and image output characteristic information; and an image information encoding unit encodes the divide image information, based on the coding parameter. Owing to the above construction, image-quality control utilizing the input image analysis information, coded characteristic information and image output device characteristic information can be performed even in a small-scale device configuration.
