    • PROBLEM TO BE SOLVED: To enhance the easiness of watching by a user by generating a reduced sequence while taking into account the perceptual relevancy of pixels or groups of pixels. SOLUTION: The present invention relates to a method for generating, from a sequence which is comprises source images and called as a first sequence, a sequence which is comprised of reduced images and called as a second sequence. Each of the reduced images has a size smaller than or equal to sizes of the source images, and the reduced image is generated by extracting, from the source image, an image part delimited in the source image by an extraction window. In the disclosed method, an initial extraction window is determined based on perceptual interest values of pixels of the source image, the initial extraction window is displaced so that the initial extraction window after displacement is centered on the perceptual relevancy gravity center of the initial extraction window before displacement, the initial extraction window after displacement is defined as the an extraction window, and thereby the extraction window is determined.

    • PROBLEM TO BE SOLVED: To improve bit rate and/or distortion control for MPEG4-AVC applications. SOLUTION: Regarding each of macro blocks in a frame containing a block of one or more transform coefficients, the percentage (ρ) of a quantized coefficient to obtain zero amplitude is determined in accordance with an application value of quantization parameters. Based on information relating to the relationship between (ρ) and quantization parameters of the macro block, in the case of processing of the macro block, an encoder output bit rate R is controlled using quantization parameter values such that the bit rate R is controlled based on R(ρ)=Θ*(100-ρ) with Θ as a constant and when controlling the encoder output bit rate R, a quantization parameter value to be applied to a current macro block is constrained by a predetermined deviation from the average of the quantization parameter values for all prior macro blocks till the current macro block.
