    • An image determination apparatus includes a frequency band signal detecting unit, an average value calculating unit, a relative value calculating unit, and an image determination unit. The frequency band signal detecting unit detects signals belonging to a plurality of frequency bands, from an image signal. The average value calculating unit calculates average values for respective ones of the signals belonging to the plurality of frequency bands detected by the frequency band signal detecting unit. Each of the average values is a characteristic value equivalent to an amplitude. The relative value calculating unit calculates a relative value of one of the average values to another of the average values, among the average values calculated for respective ones of the plurality of frequency bands. The image determination unit for determining an image based on the relative value calculated by the relative value calculating unit. The image determined is subject to image-processing.
    • 图像确定装置包括频带信号检测单元,平均值计算单元,相对值计算单元和图像确定单元。 频带信号检测单元从图像信号检测属于多个频带的信号。 平均值计算单元计算属于由频带信号检测单元检测的多个频带的各个信号的平均值。 平均值中的每一个是与振幅相当的特征值。 相对值计算单元在针对多个频带中的各个频带计算的平均值中计算平均值中的一个平均值与另一个平均值之间的相对值。 图像确定单元,用于基于由相对值计算单元计算的相对值来确定图像。 所确定的图像需要进行图像处理。

    • Influences of physiological stereoscopic elements are removed by image processing using projection transformation. A horopter-plane image projection unit 311 is designed to project a non-stereo image supplied via a signal line 129 onto a cylindrical plane (horopter plane) including a horopter circle. The size of the horopter circle is specified using, for example, the radius as horopter circle information. Additionally, the relationship with two eyes is specified by the interocular distance. A display surface right-eye projection unit 316 is designed to project an image projected on the horopter plane onto a display surface for the right eye. A display surface left-eye projection unit 317 is designed to project the image projected on the horopter plane onto a display surface for the left eye. Therefore, retinal images that are identical to each other are supplied to the two eyes to remove influences of physiological stereoscopic elements, and stereoscopic depth is given.
    • 通过使用投影变换的图像处理去除生理立体元素的影响。 双平面图像投影单元311被设计成将经由信号线129提供的非立体声图像投影到包括双眼立方圆的圆柱面(双眼飞机平面)上。 使用例如半径作为双眼圆圈信息来指定双眼轮的大小。 另外,两只眼睛之间的关系由眼间距离指定。 显示表面右眼投影单元316被设计成将投影在双眼器飞机上的图像投影到用于右眼的显示表面上。 显示表面左眼投影单元317被设计成将投影在双眼器平面上的图像投影到用于左眼的显示表面上。 因此,将彼此相同的视网膜图像提供给两只眼睛以去除生理立体元件的影响,并给出立体深度。

    • 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 ε., 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. However, with respect to the neighboring pixel for which the flag is raised, the pixel value is replaced by that of the pixel of attention C, and is calculated. The present invention can be applied to a video camera, a television receiver, etc.
    • 信号处理设备和方法,记录介质和程序,其中除边缘以外的部分可被平滑化,同时像素值陡峭的边缘被正确地保持。 在步骤S11中确定关注像素,并且在步骤S12中确定相邻像素。 在步骤S13中,计算注意像素和每个相邻像素之间的像素值的差异。 在步骤S14中,根据差值和阈值之间的大小关系,对于相邻像素和对称的相邻像素,标志被升高。 此外,鉴于注意的像素,标记升高的对称相邻像素的标志也被提升为相邻像素。 在步骤S15中,以注意像素为中心的7像素抽头通过重量进行平均。 然而,对于标志升高的相邻像素,像素值被注意C的像素值代替,并被计算。 本发明可应用于摄像机,电视接收机等
