摘要： An apparatus and method for separating a background image and an object image. The apparatus comprises an area specifying unit for specifying areas of the image. The area specifying unit specifies, in a first period-of time, an uncovered background area in which foreground object components and background object components are mixed. The area specifying unit specifies, in a second period of time, a foreground area consisting of only the foreground object components and a background area consisting of only the background object components. The area specifying unit specifies, in a third period of time, a covered background area in which the foreground object components and the background object components are mixed. A mixture-ratio calculator detects a mixture ratio indicating a ratio of the foreground object components and the background object components. A separator separates the pixel data into the foreground object components and the background object components based on the mixture ratio.

摘要： The present invention relates to an image processing device enabling detection of a mixture ratio indicating the state of mixture between multiple objects. A contour region information generating unit 421 and a normal equation generating unit 422 extracts contour region pixel data within a frame of interest positioned at a contour region with approximately a same mixture ratio, extracts corresponding pixel data from a frame different to the frame of interest, extracting background pixel data corresponding to the contour region pixel data or the corresponding pixel data, and generating an equation wherein the mixture ratio is an unknown number, based on region specifying information specifying a non-mixed region made up of a foreground region and background region and a mixed region. A least square approximation unit 423 detects the mixture ratio by solving the equation. The present invention can be applied to signals processing devices for processing image signals.

摘要： The present invention allows detection of an exposure time of an image that has already been captured. A motion detector 102 detects an amount of inter-frame movement of a foreground object in a designated frame based on the designated frame and a frame preceding or subsequent to the designated frame. A mixture-ratio calculator 104 detects a mixture ratio indicating the ratio of mixture of a foreground component and a background component in a mixed area of the designated frame. In accordance with the mixture ratio, the mixture-ratio calculator 104 detects the amount of movement of the foreground object within an exposure time in which pixel data is obtained. A shutter-time calculator 106 detects a ratio of a time interval between frames to the exposure time based on the amount of inter-frame movement and the amount of movement within the exposure time of the foreground object. The present invention is applicable to an image processing apparatus.

摘要： 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. An actual world estimating unit 17003 estimates the actual world function, assuming that the pixel value of each pixel corresponding to a position in the x direction of image data wherein real world light signals are projected on a plurality of pixels each having the time-space integration effects, and part of the continuity of the real world light signals has been lost is a pixel value acquired by integrating the actual world function corresponding to the real world light signals approximated with a spline function in the x direction. An image generating unit 17004 generates an image by integrating the actual world function in the x direction in predetermined increments. The present invention can be applied to, for example, a case of removing movement blurring from an image, a case of improving the resolution of an image, or a case of enlarging an image.

摘要： A signal processor 12 acquires a second signal obtained by detecting a first signal, as a signal of the real world, having a first dimension. The second signal is of a second dimension lower than the first dimension and has distortion relative to the first signal. The signal processor 12 performs signal processing which is based on the second signal to generate a third signal alleviated in distortion as compared to the second signal.

摘要： The present invention relates an image processing device and method, recording medium, and program. A simple-type angle detecting unit 901 simply detects the angle as continuity using correlation from an input image. A determining unit 902, based on the angle thus simply obtained, connects a switch 903 to a terminal 903a in the event the angle is closer to the horizontal direction or the vertical direction, and outputs the angle information simply detected to a regression-type angle detecting unit 904. The regression-type angle detecting unit 904 statistically detects and outputs the angle as continuity in a regression equation. On the other hand, in the event that the angle as continuity simply obtained is closer to 45 degrees, the determining unit 902 connects the switch 903 and a terminal 903b. At this time, a gradient-type angle detecting unit 905 detects and outputs the direction of continuity from the input image in a gradient equation. As a result, the angle as continuity may be detected more accurately.

摘要： A class synthesizing circuit classifies an aimed-at data item into one of a plurality of classes specified in advance, according to a plurality of data items disposed around the aimed-at data item. A coefficient holding and class-code selection circuit stores conversion information for the aimed-at data item, for each class. An estimation-prediction calculation circuit converts the aimed-at data item to a higher-quality data item according to the conversion information. The class synthesizing circuit classifies the aimed-at data item into a different class according to whether the aimed-at data item is missing.
