摘要： A method for determining a range map for a particular video frame from a digital video comprising: determining a set of extrinsic parameters and one or more intrinsic parameters for each video frame. A set of candidate video frames are defined and an image similarity score for each candidate video frame providing an indication of the visual similarity. The image similarity scores are compared to a predefined threshold to determine a subset of the candidate video frames. A position difference score is determined for each video frame in the determined subset responsive to the extrinsic parameters, and the video frame having the largest position difference score is selected. The range map is determined responsive to disparity values representing a displacement between corresponding image pixels in the particular video frame and the selected video frame.

摘要： An ink jet printer apparatus and method includes a print head having at least one nozzle. In response to a signal related to media type that is to be recorded upon, gray level image data relating to at least three different drop volumes including no ink drop are recorded at different pixel locations to form dots of different dot size or dot density on the recording medium. In recording image data of the same multitone image data value on different media, drop volumes deposited on one medium by the nozzle are different than drop volumes deposited on another medium by that nozzle. In some embodiments or printing modes image data is also recorded by depositing a variable size dot on a reference raster location and a supplementary dot at an adjacent pixel location on a shifted raster.

摘要： An ink jet print head includes an array of nozzles, each nozzle being capable of selectively producing when actuated at least two ink drop sizes including a larger ink drop size and a smaller ink drop size. In response to a pixel density signal of maximum density value at a respective pixel location, a nozzle prints a drop of the larger ink drop size at the respective pixel location on a reference raster and the same or a different nozzle prints a drop of a smaller drop size at a pixel location adjacent to the respective pixel location on a shifted raster to provide for full coverage with improved dry time capability of the printed ink drops.

摘要： An image processor performs error diffusion by thresholding an incoming gray pixel to black or white, comparing the difference between the black or white print value and the incoming pixel gray level and superimposing the difference on the next pixel gray level. The threshold value is read out from a threshold matrix which has been modulated with a pattern which is complementary to the known artifact pattern of the error diffusion process. Typically, the threshold matrix has sparce threshold values along one of its diagonals, the direction of the diagonal being perpendicular to the prevailing direction of artifacts generated by the error diffusion algorithm.

摘要： An image processor converts a multiple gray-level image to a bi-tonal image using both error diffusion and ordered dither to enhance image quality. The error diffusion process is attenuated smoothly as the local area intensity approaches a light or dark maximum, while the ordered dither process is attenuated smoothly as the local area high spatial frequency content increases.
