The aim of the present invention is to provide a VDT stress mitigating devic e and method capable of mitigating VDT stress caused by a regular spatial pattern and VDT stress caused by flicker generated by an interlaced format, a VDT stress ris k quantifying device and method, and a recording medium. An A/D conversion section 10 imports interlaced format video signals P1 from an external image signal output devi ce and converts them in field units by A/D conversion into image data D1. A filter section 2 0, while not distinguishing between the first field and the second field, and while maintaining the temporal order of these fields, performs a temporal filtering process on the image data of each field. A D/A conversion section 30 converts the image data D2 that has undergone the temporal filtering process by the filter section 20 into image signals P2 based on an interlaced format by D/A conversion. The image signals P2 are then sequentially outputs according to the temporal order of the fields.
