Patent number: 7773824Abstract: The present invention relates to a signal processing apparatus and a method, a recording medium, and a program, in which portions except an edge can be smoothed while the edge whose change in pixel value is steep is held correctly. A pixel of attention is determined in step S11, and a neighboring pixel is determined in step S12. In step S13, a difference in pixel values between the pixel of attention and each neighboring pixel is calculated. In step S14, according to a relationship in size between the difference and a threshold value ?., flags are raised for the neighboring pixel and a neighboring pixel which are symmetrical. Furthermore, a flag is also raised for a neighboring pixel away from, in view of the pixel of attention, the symmetrical neighboring pixel for which the flag is raised. In step S15, 7-pixel taps centered around the pixel of attention are averaged by weight.Type: GrantFiled: April 19, 2004Date of Patent: August 10, 2010Assignee: Sony CorporationInventors: Shintaro Okada, Kazuhiko Ueda, Mitsuyasu Asano, Takeshi Kubozono, Kazuki Yokoyama
