摘要： A luminance signal obtained by negative-positive inverting and gamma-correcting a signal indicating an image on a negative film and a contour correction signal Y.sub.ap generated from the luminance signal Y are input, and a signal Y.sub.ap1 and a signal Y.sub.ap2 are obtained by an adder, a subtractor and an adder in accordance with following equations: Y.sub.ap1 =Y.sub.ap -kY, Y.sub.ap2 =Y.sub.ap +kY, where K is a damping coefficient. Next, a slice circuit picks out signals having a higher level than the maximum level of the noise element, from the signal Y.sub.ap1 generated as mentioned above and another slice circuit picks out signals having a lower level than the minimum level of the noise element, from the signal Y.sub.ap2. An adder adds up these picked-out signals to be used as the noise free contour correction signal.

摘要： An apparatus achieves an exposure control for getting an image with the best SN without a mechanical iris and an image processing which is good at the color-reappearance and the gradation property with a simple digital processing circuit. When the film image is read by the line sensor 14 which has an electric shutter function, the electric shutter, the film feeding speed and the analog amplifier 16 are controlled totally so as to obtain images with the best SN from high to low transmittance negatives. And, when the dot sequential R, G, B digital signals are processed digitally, the offset values and the gain volumes of the respective R, G, B are calculated based on the maximum value and the minimum value which are detected by the respective R, G, B digital signals, the calculated offset values of the respective R, G, B are added to the dot sequential R, G, B digital signals which are obtained during the re-scanning, and the calculated gain volumes of the respective R, G, B are multiplied by the offset dot-sequential R, G, B digital signals so as to adjust the white balance and the black balance.

摘要： A film correction system adjusts a relative position of film containing an area for information and a scanner of the film area. The system includes a scanner for scanning the film area at a film plane. A film drive moves the film along the film plane. A focused beam separate from the film area scanner scans a film edge in the film for determining a location of the film edge. A circuit is coupled to the focused beam scanner for changing a relative position of the film area scanner and the film area. The film edge scanner is a flying spot scanner, and the apparatus includes signal processors for processing the sprocket information. The system may be retrofit to an existing telecine apparatus. A separate coil may be used to provide deflection of a flying spot scanner used to scan the picture information on the film.

摘要： A method and apparatus for controlling the positioning of a filmstrip in a film scanning gate using signal states derived from a pair of spaced film sprocket holes or perforation ("perf") sensors on either side of the film scanning gate in conjunction with line scan counts and filmstrip drive, stepper motor half-step counts. The filmstrip is advanced by the stepper motor in a pre-scan operation through the film scanning gate for line scanning the image frames at a low resolution and advanced in the reverse direction back into the film scanning gate for high resolution scanning in a main-scan operation. A line scan array of line scan counts and half-step counts as well as first and second perf arrays of half-step counts and perf sensor states are generated in the pre-scan operation. Image frame borders are located in the pre-scan operation as border line scan counts and correlated in the line scan array to the half step counts to go to in the main-scan. During main-scan, the filmstrip image frames are positioned in the scanning gate by reverse drive of the stepper motor in a coarse and fine alignment process employing the half step counts to go to and the state transitions in the first and second perf arrays. Filmstrip jams, slips and perforation defects are detected from perf state durations in the perf arrays in relation to the associate half-step counts.

摘要： A system that determines the integration time periods for the channels of a color scanner. The slowest channel or longest time period is used to set a line scan clock period or transfer clock period of the scanner. The exposure start times for the other channels, which are charged faster than the slowest channel, are set relative to the transfer clock. The transfer clock and exposure start time of all channels is adjusted if necessary for the density of the film being scanned.

摘要： In a digital film scanner, invalid image pixel data is identified by a logic circuit which responds jointly to an over range signal from the scanner analog to digital converter and the most significant bit of the pixel data. The logic circuit discriminates between input pixel analog voltages representing valid maximum or minimum pixel data values and values which are outside the conversion range of the A/D converter which correspond to invalid pixel data. An image processing computer selectively responds to these indications to substitute nearby valid pixel data for calculation and to provide appropriate operator warnings or even system shutdown depending on the number of successive invalid pixel data occurrences.
