  • Patent number: 7602440
    Abstract: The present invention relates to an image processing apparatus and method, a recording medium, and a program that can very sharply display video images which are subjected to frame rate conversion by suppressing a decrease in the image quality (blurred images) caused by imaging blur. A high frame converter 11 performs high frame rate conversion on an input moving picture. An imaging blur suppression processor 13 corrects each pixel value forming a subject frame based on at least one value corresponding to the subject frame of the parameter values representing imaging blur detected by an imaging blur characteristic detector 12. Accordingly, a moving picture having a higher rate than that of the input moving picture and having each pixel value suitably corrected to suppress imaging blur is output. The present invention is applicable to a television system.

  • Patent number: 7558435
    Abstract: In each of stages of a nonlinear filter, a successively determined target signal and plural adjacent signals are weighted-averaged with plural sets of different coefficients to calculate plural smoothed signals. Differences in level between the target signal and each of adjacent signals and signals arranged within the predetermined interval from the each of the adjacent signals are compared with a threshold value. According to the comparison, flags are set to the adjacent signal, to an adjacent signal arranged at a symmetrical position, and to adjacent signals arranged beyond the adjacent signals. The intervals of adjacent signals are different among stages. The target signal in level is used instead of the adjacent signals with smoothed signals, which are selected according to the flags. Weighting coefficients may be calculated on the basis of the comparison result, and smoothed signals may be synthesized according to the weighting coefficients.

  • Patent number: 7260268
    Abstract: An input signal is accurately separated into a component in which a change in signal level is sharp and having a large edge, and the other components. A narrow band non-linear filter extracts an edge component in a relatively narrow frequency band from an input signal and outputs the signal. A wide band non-linear filter extracts an edge component in a relatively wide frequency band from the input signal and outputs the signal. A selector outputs a signal composed of the signal where an edge portion is replaced, based on a differentiated value of the signal sent by a differentiator, as the edge component of the input signal. An adder subtracts an output signal from the input signal and outputs the calculated output signal as the edge component of the input signal. This process, may be applied to an image processor.
