For Season 1, the source is of nothing special. Its native resolution is 720p, then upscaled by a poor algorithm. This leads to many defects: lines featuring severe aliasing and ringing as well as serious ringing on the image borders. Dark scenes are widely spread throughout Season 1, together with the plentiful use of dark fades, resulting in heavy colour banding.
For the lines, most of the problems can be solved by descaling and reconstruction, then slight AA and moderate de-ringing as supplements. For colour banding, since most scenes have only a little colour banding, in order to deal with severe colour banding in dark scenes, we designed a complex mask for protection in combination with luminance information. We also use a colour banding detection algorithm. Thanks to all those, we finally adaptively controlled the strength of de-banding. At the end, we added some grains to improve the viewing exprience.
As to Season 2, the source is much better, with a native resolution of 1080p. The sharpness is significantly improved compared to Season 1. There's no doubt that this was a next generation work at its time (2013), still rarity nowadays. Unfortunately, there are still some scenes with the same heavy colour banding as Season 1. What's more, the over-sharp lines leads to severe aliasing. We applied regular AA and de-ringing, then similar de-banding method as Season 1 with a lower strength.
Haiyore! Nyaruko-san F has an excellent image quality. The native resolution is a bit less lower compared to Season 2, but still close to FullHD. The lines are almost fine, and the colour banding issue is much improved. Our processing methods were basically the same as Season 2, but the strength was all reduced.
The other OVAs and clip shows were treated with the same processing before. The only diffenrence comes from the clip show for Season 2, which features very serious ringing, probably due to post-scaling. We applied a strong de-ringing process to remove it.
The flash anime is quite simple, with only serious aliasing. We applied some regular processing on it.
