Képpontonként

Képpontonként is a Hungarian term that translates to "per pixel" or "from the viewpoint of each pixel" in English. It is commonly used in digital imaging and computer graphics to describe operations or analyses that are performed individually on each pixel within an image. This granular approach allows for detailed manipulation and understanding of image data.

In image processing, képpontonként operations are fundamental. For instance, adjusting the brightness or contrast of an image often involves modifying the color value of every single pixel based on a specific formula. Similarly, applying filters, such as blurring or sharpening, is typically done képpontonként, where the new value of a pixel is calculated based on its original value and the values of its neighboring pixels.

In computer graphics, the concept of képpontonként is crucial for rendering. Shading models, which determine the color and intensity of light reflected from a surface, are calculated for each pixel on the screen. This ensures that lighting effects, textures, and material properties are accurately represented across the entire rendered image. Ray tracing, a rendering technique, also operates képpontonként by casting a ray from the camera through each pixel into the 3D scene to determine its color. The term emphasizes the discrete, individual nature of pixel processing in these fields.
