[0004] However, the signal processing for estimating the first signal from the second signal has not taken into account the fact that the lower dimensional A second signal of a second dimension in which partial continuity of the real-world signal is lost has a data continuity corresponding to the stability of the real-world signal that has been lost

Embodiment Construction

[0353] Figure 1 illustrates the principle of the invention. As shown in the figure, an event (phenomenon) having, for example, space, time, quality, etc., in the real world 1 is acquired by a sensor 2 and forms data. Events in the real world 1 refer to light (image), sound, air pressure, temperature, mass, humidity, brightness / darkness, or motion, etc. Events in the real world 1 are distributed in the space-time direction. For example, the image of the real world 1 is the distribution of the light intensity of the real world 1 in the space-time direction.

[0354] Note the sensor 2, for events in the real world 1 having dimensions of space, time, and quality, the sensor 2 converts the events that can be acquired by the sensor 2 in the real world 1 into data 3 . It can be said that information representing events in the real world 1 is acquired by the sensor 2 .

[0355] That is, the sensor 2 converts information representing events in the real world 1 into data 3 . It can ...

Abstract

The present invention takes into consideration the real world where data was acquired, and enables obtaining of processing results which are more accurate and more precise as to phenomena in the real world. A data continuity detecting unit 101 detects the continuity of data of second signals, having second dimensions that are fewer than first dimensions had by first signals which are real world signals and are projected whereby a part of the continuity of the real world signals is lost, wherein the continuity to be detected corresponds to the continuity of the real world signals that has been lost. An actual world estimating unit 102 estimates a real world image by estimating the continuity of the real world image that has been lost, based on the continuity of the data detected by the data continuity detecting unit 101.

Description

technical field [0001] The present invention relates to a signal processing device, method and program, and more particularly to a signal processing device, method and program considering the real world from which data is acquired. Background technique [0002] A technique of detecting phenomena in the real world (real world) using sensors and processing sampled data output from the sensors is widely used. For example, image processing techniques are widely used in which the real world is imaged with an imaging sensor and sampled data as image data is processed. [0003] In addition, Japanese Unexamined Patent Application Publication No. 2001-250119 discloses obtaining a second dimension lower than the first dimension by using a sensor to detect a first signal which is a real world signal having the first dimension obtaining a second signal comprising distortion relative to the first signal; and performing signal processing based on the second signal to produce a third sign...
