Abstract:
1. An image-processing apparatus for encoding a moving picture frame-by-frame, comprising: a coefficient memory which stores a plurality of coefficient sets corresponding to resolutions of frames and encoding methods of frames; a selector, arranged to acquire information indicating a resolution of a frame to be encoded, and to select, from the coefficient memory, a coefficient set based on the resolution and whether the frame to be encoded is an intra-coded picture to which intra-frame coding is applied, or a predictive coded picture which is encoded referring to another picture; an extractor, arranged to extract a feature amount of the frame to be encoded; a generator, arranged to generate, in a case that the frame to be encoded undergoes inter-frame predictive coding, a function representing a relationship between a quantization step and an amount of generated data based on the selected coefficient set and the feature amount; and a setting section, arranged to set, in a case that the generator generates the function, a quantization step according to a target amount of code based on the function in encoding of the frame to be encoded.
