A method for deriving a synchronisation signal (35) from a video signal comprises tracking the blanking level (107) of the video signal with first and second slice level signals (26, 27) and tracking the sync tip level (110) of the horizontal sync signal (109) of the video signal with third and fourth slice level signals (28,29) for determining the blanking level (107) and the sync tip level (110). A value for an intermediate slice level signal (30) is computed from the first, second, third and fourth slice level signals (26, 27, 28, 29) so that the value of the intermediate slice level signal (30) lies approximately halfway between the blanking level (107) and the sync tip level (110). The video signal is compared with the intermediate slice level signal (30), and the synchronisation signal (35) is prepared from a logic signal by transitioning the logic signal from one of the logic high and logic low levels to the other of the logic high and logic low levels, each time the video signal transitions across the intermediate slice level signal (30).

The present invention relates to a stabilizer for a video camera. An upper arm consists of one stabilizing spring and two square light-weighted aluminum alloy plates, and a lower arm consists of two springs and three square light-weighted aluminum alloy plates. The upper ends of the two square light-weighted aluminum alloy plates of the upper arm are movably connected with a connecting rod below a holder respectively, and the other ends are movably connected with the upper ends of the three square light-weighted aluminum alloy plates of the lower arm through an upper arm connecting plate and a lower arm connecting plate. The lower ends of the three square light-weighted aluminum alloy plates of the lower arm are movably connected with a universal member, and a stabilizing spring is connected between the connecting rod below the holder and the upper and the lower arm connecting plates. Two stabilizing springs are connected between the upper and the lower arm connecting plates and the universal member 6 so as to form a double-arm stabilizing structure. The stabilizer combines the high stability of a Steadicam stabilizer and the portability of a handheld stabilizer, simplifies the inner structures of the two arms of the Steadicam stabilizer, and guarantees higher stability than a video camera, while having relatively simple structure and low cost.

The invention discloses a method for producing cotton fiber three-dimensional pictures, which includes the following steps: 1. degreasing, bleaching, dyeing and combing cotton fibers; 2. designing a picture and mounting the picture to produce a drafting board; 3. selecting picture forming portions, applying white latex and drying; 4. producing corresponding components with raw material 1 according to the picture forming portions and wetting partially; 5. covering components gradually from far to near according to the picture; 6. wetting all or partial components with water by a writing brush, so that the viscosity of the wetted white latex on the picture plate surface is recovered and the components are adhered; 7. drying and trimming the cotton fiber picture, and using colorless misty glue solution for forming; and 8. framing the picture. According to the method, the animal, landscape and figure pictures are made of cotton fibers, lifelike in image, wide in material source, simple in picture production, low in cost, good in economical benefit and high in art appreciation value and practical value.
