File:Nes ntsc perscanline.gif: Difference between revisions
(uploaded a new version of "File:Nes ntsc perscanline.gif": Fixed the horizontal displacement error. Also added (subtle) dithering to help overcome the color differences arising from quantization (reduction to 256 colors).) |
(uploaded a new version of "File:Nes ntsc perscanline.gif": Replaced with version where correct palette is forced for the NES colors, and dithering is disabled) |
(No difference)

A testcard picture, intentionally resembling Philips PM5544, but rendered with NES colors.
Rendered in 2048x240, then pixel-upscaled to 2048x1920, then lanczos-downscaled to 584x480. This method of scaling was chosen to best inhibit scaling related artifacts.
This image is part of a set illustrating the differences between palette-and-pixel-based and scanline-and-ntsc-signal-based rendering in NES emulation. This image shows the scanline-and-ntsc-signal-based rendering.
Note that the colors are not perfectly reproduced from the original rendering, due to GIF palette reduction. A NeuQuant-based method was used in order to generate the most optimal palette to represent it.
