Übersetzung für "Pixel value" in Deutsch

This maximum pixel value is applied to a multiplier 17 and to a further multiplier 18.

Return value: The function returns the pixel value.

As a result, a decoded pixel value for the respective pixel is present.

For every pixel of the image sensor, the camera device provides a pixel value.

The unit of a pixel value may be, for example, HU (Hounsfield Unit).

Here the new pixel value will be allocated with the already existing in the matrix memory.

To this end a maximum-value detector 16 is provided which supplies the maximum pixel value of the previous scanning line.

As explained, the difference values namely only correspond to the deviation of the prediction from the actual pixel value.

Such a quantized pixel value is also called an index value in connection with the invention.

This is done by means of a predetermined brightness value quantization rule and corresponds to a quantization of the respective actual pixel value.

These estimated intermediate image zone values are then additionally taken into account for the prediction of the estimated pixel value of the respective pixel.

However, other or additional parameters can also be taken into account for the prediction of an estimated pixel value.

On the other hand, an intensity value corresponding to the surface temperature of the associated surface element is assigned to each pixel as a pixel value.

In one preferred embodiment of the invention, the pixel value being analyzed is the gray-scale value of the pixel.

The position and size of the element can also be entered as a pixel or percentage value.

For each homogeneous pixel a gray value plane is fitted to its 3x3 neighborhood.

Threshold below which a pixel value is considered black (default: 32).

Mosaic: blurs the image by dividing the photograph into rectangular cells and then recreates it by filling those cells with average pixel value.

The invention relates to a method of scanning an X-ray image by means of a plurality of electrometer probes which scan charge patterns of a photoconductor which is locally uniformly charged prior to the X-ray exposure and is discharged by the exposure in dependence on the intensity of the X-rays, the surface of the photoconductor being scanned after the exposure in order to determine the charge density, the electrometer probes forming for each pixel a pixel value which corresponds to the discharge at the relevant pixel.

After the scanning operation, the scanning value memory 10 stores one complete X-ray image which contains for each pixel a pixel value which corresponds to the discharge at the relevant pixel.

The output signals thus produced by the electrometer probes are further processed after an analog-to-digital conversion, for each pixel there being formed a pixel value which corresponds to the discharge at the relevant pixel.

The invention relates to a device for scanning a charge image which, during exposure to X-rays, is generated on a previously locally uniformly charged photoconductor as a function of the local intensity of the X-rays, using a plurality of electrometer probes which are arranged in a row and which line-wise scan the charge pattern of the photoconductor which is successively displaced in the scanning direction which extends perpendicularly to the line direction, the probes supplying for each pixel an image value which corresponds to the discharge at the relevant pixel.
