回路。[Claims for Utility Model Registration] 1. The image signal recording system includes a first switch circuit that enables/disables a filter circuit that removes chroma frequency band components from a luminance modulation signal of a recorded image, and this switch circuit. 1. A recording/reproducing circuit for a still video system, comprising: a second switch circuit for mixing a chroma modulation signal with a luminance modulation signal passed through the filter circuit when the filter circuit is enabled. 2. The reproduction system for the image signal recorded by the recording system includes a path for separating and extracting a luminance modulation signal and a chroma modulation signal from the reproduction modulation signal, and a path for directly converting the reproduction modulation signal into a reproduction modulation luminance signal. A recording/reproducing circuit for a still video system according to claim 1, which is provided with a switch circuit for switching to a still video system.
