Nes_ntsc_perscanline.gif (584 × 480 pixels, file size: 139 KB, MIME type: image/gif, looped, 3 frames, 0.1 s)
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.
