7results about How to "Avoid ghosting" patented technology

This application relates to the field of packaging and printing technology, and discloses an outer packaging printing device, including a base plate, a printing component, and an elastic component. In this outer packaging printing device, the base plate integrates an unwinding component, a pressure roller, and a rewinding component, forming a continuous printing path. In the printing component, the printing roller inside the printing chamber is evenly inked through a sponge block and capillary tube. An L-shaped plate cooperates with a first sliding groove, and a servo motor drives a lead screw and guide rod to adjust the position of the printing roller, matching it with the pressure roller to accommodate substrates of different thicknesses. In the elastic component, the guide roller slides through a second sliding groove, and a limiting rod is linked with a telescopic spring to dynamically compensate for the pressure between the pressure roller and the printing roller, avoiding wrinkles or ghosting. A controller coordinates various electrical components, simplifying the operation process. The anti-slip design at the bottom of the support column enhances stability. This device, by simplifying the mechanical layout, solves the problems of poor printing adaptability and low adjustment efficiency in existing technologies, comprehensively improving printing accuracy and compatibility.

This utility model discloses a novel flexible printing plate clamping device, comprising a base plate and a support frame. The support frame is mounted on the top of the base plate, and a cylinder is mounted on the top of the support frame. Slide rails are symmetrically mounted on the top of the base plate away from the support frame. Movable plates are disposed outside the slide rails, and sliders are slidably mounted on the surfaces of the slide rails. Support plates are symmetrically mounted on the bottom ends of the movable plates, and each support plate is connected to a slider. A rotating box is mounted on the top of the support plate away from the movable plate, and support seats are symmetrically mounted on the top of the base plate near the slide rails. This utility model not only enables convenient replacement of flexible printing plates, reducing manual labor intensity and improving the efficiency of the printing plate clamping device, but also allows the printing plate clamping device to elastically press down the fabric for printing, avoiding ghosting or blurring during printing and improving the printing quality of the printing plate clamping device.

The present application relates to a kind of single exposure Raw video HDR reconstruction method and system, belong to computer vision and image processing technical field.The method comprises: obtaining single exposure bayer format Raw video sequence;Channel decomposition parallel alignment module is constructed, and input frame is decomposed into full channel flow, red blue channel flow and double green channel flow three parallel branches, using the physical characteristics that red blue channel is not easy to saturate in highlight area and green channel high signal-to-noise ratio, respectively, different feature extraction and alignment are carried out;Exposure complementary mask guided repair module is constructed, by calculating overexposure mask and dividing timing complementary area, using normal exposure information of adjacent frame in complementary area to repair the overexposure area of current frame;Multi-stream features are fused using cross attention mechanism, and high dynamic range video frame is reconstructed by combining mask guided color loss.The present application effectively solves the problem of highlight overflow and dark noise without alternating exposure, avoids ghosting artifacts, and significantly improves the reconstruction quality of HDR video.
