  • Patent number: 7181081
    Abstract: Scenes from motion pictures to be colorized are broken up into separate elements, composed of backgrounds/sets or motion/onscreen-action. These background and motion elements are combined into single frame representations of multiple frames as tiled frame sets or as a single frame composite of all elements (i.e., both motion and background) that then becomes a visual reference database that includes data for all frame offsets which are later used for the computer controlled application of masks within a sequence of frames. Each pixel address within the visual reference database corresponds to a mask/lookup table address within the digital frame and X, Y, Z location of subsequent frames that were used to create the visual reference database. Masks are applied to subsequent frames of motion objects based on various differentiating image processing methods. The gray scale determines the mask and corresponding color lookup from frame to frame as applied in a keying fashion.

  • Patent number: 5402166
    Abstract: A film instability compensating system compensates for the effects of film instability in a film gate. The film instability compensation system includes a positional transducer for measuring the position of the film edge relative to a sprocket hole which is maintained in contact with a sprocket tooth by a pressure roller. The positional transducer measures the distance between the film edge and a sprocket hole and then measures deviations from the distance for subsequent sprocket holes to determine a compensation signal. The output of the positional transducer is coupled to a delay unit which delays the signal corresponding to the error at a particular sprocket hole until that sprocket hole reaches the film gate. Signals representative of the cyclic errors caused by the relative lateral displacement of the sprocket holes, are stored in a memory and are applied to a subtractor circuit.

  • Patent number: 5327247
    Abstract: A signal produced by a telecine suffers from losses and defects caused by differences in response to incident light between different areas of the screen area scanned. These differences may arise from burning of the screen, blemishes, dirt in the system, differences in grain size of phosphor particles, missing particles, and losses in the internal optical system of the machine. The invention divides the scanning area into a correction map and devises for each area a correction factor based on the response of that area to incident illumination. When a defect is detected, video data from an adjacent area is substituted. Correction factors are held in a look-up RAM and output to a multiplier where they are multiplied with video data. The video data input to the multiplier may be suppressed and a test pattern may be loaded into the multiplier.
