SIGNAL PROCESSING DEVICE, SIGNAL PROCESSING METHOD, PROGRAM, AND RECORDING MEDIUM

摘要

There are provided a signal processing device, a signal processing method, a program, and a recording medium capable of obtaining an image approximating to a signal of the real world. A real world estimation section (17003) estimates a real world function by assuming that a light signal of the real world is projected to a plurality of pixels each having temporal/spatial integration effect and the pixel value of each pixel corresponding to a position in the x direction of the image data lacking in a part of steadiness of the light signal of the real world is a pixel value obtained by x-direction-integrating the real world function corresponding to the light signal of the real world approximated by the spline function. An image generation section (17004) generates an image by integrating the real world function in the x direction in a predetermined unit. The present invention can be applied, for example, to a case for removing motion blur from an image and improving the image resolution, or when enlarging the image.
