A method and device for deblurring an image having pixels.
A stable image can be insured in a distance section and a reading section, and blurring, ghost or the like of an image can be prevented to produce a clear image.
The unblurring process consists of convolving this finely sampled blurred image with a specially designed convolution mask.
The image processor (13) eliminates a ghost image caused when a blurred image of an object covers the peripheral part.
Depending upon which object is being viewed, an in-focus and a blurred image appear simultaneously on the user's retina.
In one implementation, a system combines a blurred image with a corresponding noisy image of the same subject to create a high-quality deblurred image.
A low-pass filter is performed on image A to obtain a blurred image B1 with noise and signal suppressed.
The out-of-focus image comprises a light spot image object for the light spot with this image object having a speckle pattern.
The blur function is obtained from a probability distribution relating a sharp image, a blurred image and a fixed blur estimate.
The method according to the invention makes it possible to restore a blurred image acquired by means of a camera fitted to a communication terminal.
Specifically, a relative movement can be determined from a spatial analysis of a single out-of-focus image.
The resulting blurred image is deconvolved to generate, in one embodiment, a two-dimensional projection image of three dimensional of the object (figure 1).
In accordance with the method, the front side image is printed as an original high quality image.
The backside image is printed as a blurred image.
When the image is captured, the effect of relative motion between the camera and the subject is that it transforms the true image into a blurred image according to a 2-dimensional transfer function.
Disclosed are a device and method in computer graphics for acquiring a blurred image with reduced memory usage.
A process is carried out that stores all SATs and leaves only computation results of required columns, without deriving a blurred image.
This blurred image (113, 213) is assessed by detector elements (14, 114, 214) which produce a signal indicating the proximity of the object (16).
A camera (111) captures at least one out-of-focus image of at least a part of the surface (103) comprising the light spots.
A means is provided to effectively generate a defocus image in a three-dimensional CG, thereby making it possible to carry out a real time display.
In addition, the universal bracket (1) is designed to be rigid and prevent the camera from vibrating in order to prevent a blurred picture on a display unit.
