Problems solved by technology

[0004] However, the signal processing for estimating the first signal (image signal) from the second signal (image signal) has not taken into account the fact that the first signal generated by the first signal which is a signal of the real world having the first dimension is larger than The second signal (image signal) of the second dimension having a low dimensionality of the first dimension in which part of the continuity of the real-world signal is lost has data continuity corresponding to the stability of the real-world signal that has been lost

Embodiment Construction

[0406] 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.

[0407] 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 .

[0408] That is, the sensor 2 converts information representing events in the real world 1 into data 3 . It can ...

Abstract

The present invention relates to an image processing device and method, and a program, capable of obtaining processing results which are even more accurate and even more precise as to events in the real world, taking into consideration the real world where data has been acquired. In the event that the light signal in the actual world 1 represented with the light signal function F has predetermined continuity, the actual world estimating unit 102 estimates the light signal function F by approximating the light signal function F with a predetermined approximation function f using weighting provided in accordance with importance to the pixels within an input image (image data including continuity of data corresponding to continuity) from the sensor 2, and data continuity information (data continuity information corresponding to continuity of the input image data) from the data continuity detecting unit 101. The present invention can be applied to an image processing device.

Description

technical field [0001] The present invention relates to an image processing device, method and program, and more particularly to an image 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 (image signal) comprising a distortion relative to the first signal; and performing signal processing (image processing) based on the s...
