The invention concerns quinazoline derivatives of Formula wherein each of Q1, Z, m, R1, R2, R3 and Q2 have any of the meanings defined in the description; processes for their preparation, pharmaceutical compositions containing them and their use in the manufacture of a medicament for use as an anti-invasive agent in the containment andor treatment of solid tumor disease. The light system can have a low profile configuration for improved aesthetics and aerodynamics. This avoids the sagging of the sheet material between the purlins at the time when the hard roof panels 37 are fastened to the purlins. A output section 50 combines the image data DBf of the motion-blurring-mitigated object image into a space-time location corresponding to the motion vector detected in the image based on background component image data DBb, to generate image data DVout of the motion-blurring-mitigated image. Further, duplicate videos can be detected and discarded in order to preserve storage space.
