    • The present invention relates to a signal processing device and signal processing method, and program and recording medium, whereby images and the like closer approximating real world signals can be obtained. With regard to an input image of dimensions fewer than the dimensions of actual world light signals, wherein actual world light signals have been projected and a part of the continuity of the actual world light signals has been lost, actual world signals are estimated at an actual world signal estimating unit 10003 from the input image within a processing region set at a processing region setting unit 10001, corresponding to continuity set at a continuity setting unit 10002. On the other hand, information relating to at least one of processing region, continuity, and actual world signals, is supplied from a user I/F 10006 to the processing region setting unit 10001, continuity setting unit 10002, or actual world signal estimating unit 10003, according to user operations. The present invention can be applied to, for example, cases of removing movement blurring from an image, for example.

    • A motion-setting section (61) sets a motion amount and a motion direction for obtaining processing coefficients. A student-image-generating section (62) generates student images obtained by adding a motion blur to a teacher image not only based on the set motion amount and the set motion direction but also by changing at least one of the motion amount and motion direction in a specific ratio and student images obtained by adding no motion blur to the teacher image. A prediction-tap-extracting section (64) extracts, in order to extract a main term that mainly contains component of the target pixel, at least a pixel value of pixel in the student image whose space position roughly agrees with space position of the target pixel in the teacher image. A processing-coefficient-generating section (65) generates processing coefficients for predicting the target pixels in the teacher images from the pixel values of extracted pixels based on a relationship between the pixels thus extracted and the target pixels in the teacher images. The processing coefficients that are suitable for any motion blur removing which is robust against any shift of the motion vector can be generated through learning.

    • A motion vector detection section detects a motion vector by using an image that is made up of multiple pixels and acquired by an image sensor having time integration effects. A time resolution creation section generates an image that has a higher time resolution by using the detected motion vector and the image made up of the multiple pixels. A motion-blurring-mitigated image generation section generates a motion-blurring-mitigated image in which motion blurring of a moving object is mitigated by using the detected motion vector on the assumption that a pixel value of pixel of the moving object in the image is a value obtained by integrating, in a time direction, a pixel value of each pixel in which no motion blurring that corresponds to the moving object occur as it is moved.
    • 运动矢量检测部分通过使用由具有时间积分效应的图像传感器获取的由多个像素构成的图像来检测运动矢量。 时间分辨率创建部通过使用检测到的运动矢量和由多个像素构成的图像来生成具有较高时间分辨率的图像。 运动模糊减轻图像生成部生成运动模糊缓和图像,其中通过使用检测到的运动矢量来减轻运动对象的运动模糊,假设图像中的运动对象的像素的像素值为 通过在时间方向上对运动对象中没有运动模糊的每个像素的像素值进行积分而得到。
