'''.KQP''' is a raster graphics format associated with ''Konica Picture Show'', and related software (''PC PictureShow''). Konica Picture Show seems to have been a 1990s-era photo development service that provided digital images on floppy disk.

The .KQP file extension was probably derived from ''Konica Quality Photo'', a division of Konica. It is also alleged to stand for ''Konica Quality Picture''

== Format details ==
KQP format is an incompatible extension of [[BMP]].

A KQP file contains embedded [[JPEG]] data, but it lacks the critical DQT and DHT segments, so it can't just be extracted as a standard JPEG file.

== Identification ==
Known files start with bytes {{magic|42 4d 00 00 00 00 00 00 00 00}}, and have {{magic|4a 50 45 47}} ("{{magic|JPEG}}") at offset 30.

They also apparently have {{magic|44 00 00 00}} at offset 14, indicating a BMP "INFOHEADER" size of 68. This is distinctive, but hasn't been confirmed to be true for all KQP files.
