摘要： A method and apparatus for interactively modifying an image defined by original digital data, representing the color content of pixels of the image at a first resolution. The apparatus comprises a first store (4;12) for storing the digital data of the pixels at the first resolution; a monitor (9); a digitizing table (5); and an image processor (6;13,15). The image processor (6;13,15) is responsive to signals from the digitizing table (5) to select a modification algorithm and a portion of the image stored in the first store (4;12) to which the algorithm is to be applied. The image processor is further adapted to modify a subset of pixels of the image portion in accordance with the selected algorithm and to cause the modification image portion to be displayed on a monitor (9) at a second, lower resolution under the control of the modified pixels, and to modify and display successive subsets of the high resolution pixels while the same image portion and algorithm are selected and until all the high resolution pixels within the selected portion have been modified.

摘要： In making a reproduction of a coloured original, two or more colour separations are prepared in one scanning operation by circumferentially spacing around an output cylinder two or more films to be exposed (or other output surfaces to be treated) to form colour separations, and in each revolution of relative rotation between the cylinder and a reproducing head, the output of the reproducing head is modulated in turn with signals representing one line of each of the two or more separations. Subsequent lines are exposed or treated in subsequent revolutions until the last line of each separation has been scanned.

摘要： 976,231. Automatic character reading. CROSFIELD ELECTRONICS Ltd. Jan. 17, 1962 [Jan. 20, 4961], No. 2409/61. Heading G4R. In character recognition apparatus of the kind which scans a character to obtain a waveform which is sampled in a tapped delay line 3 and positive and negative representations of each sample are derived, maximum or minimum signal selector circuits T1-T14 each connected to selected ones of the tappings, a recognition network for each possible waveform and connections to each network from certain of the tappings and from one or more of the maximum and minimum selector circuits and decision means adapted to select one of the outputs of the recognition networks. The signals at the tappings of the delay line are amplified positively and negatively in amplifiers B1-B20. For each character there is a selector T1-T14 which consists of a diode gate adapted to pass a negative signal when all the inputs are negative. The waveform for the character "0" is shown in Fig. 3. The "0" gate is connected to receive the signals S1,S2 (inverted) and S3. When the "0" waveform is properly located in the delay line the gate gives an output pulse which is applied through a suitable weighing resistor RW to the correlation networks for certain other characters. Selected amplifier outputs are connected directly to suitable weighting resistors of the correlation networks. The arrangement is such that when a character waveform is in the delay line the corresponding network gives a maximum signal. Also applied to each network is the output from selected gate circuits T1-T14. These signals being negative, suppress the output from the network. The arrangement is such that the gates responding to a "0" signal suppress the outputs of networks of characters which may otherwise be confused with it. It may happen that, due to defective printing, signals are produced from more than one network. A reject circuit 10 will reject a character producing more than one recognition signal. To prevent this, weak recognition signals e.g. less than 50% of the highest are suppressed by a feed back from the amplified output of each recognition network to every other network. The feed-back signals are applied through resistors Rd. The value of this resistor with respect to the resistor RJ feeding back the amplifier output to its own input, determines the suppression level of the feed back. Timing:- At the instant the waveform is properly positioned in the delay line the gates g are opened to pass the recognition signal. This instant is found by taking off a signal from the delay 3 three stages before the end and applying it to a branch delay line 16 consisting of three stages. The amplitude of the signal passed to delay line 16 is normalised by an automatic gain control circuit 13 controlled by the peak-level of the characteristic waveform picked off earlier in the delay line and stored in a capacitor in the detector 15.

摘要： Apparatus for assembling images together in which each image is defined by respective pluralities of sets of data values, each set corresponding to a group of pixels of the image, the groups being arranged in a regular array across the image whereby the sets of data values can be obtained from sets of first data each defining the color content of an image pixel in the group. The apparatus comprises a control system for determining the position of a first image relative to a second image in a desired assembled image; an assembled image store; and a modified image store. The control system is operable to convert the sets of data values of the overlapping groups of pixels defining a region of the assembled images which overlaps and which is to be retouched into the corresponding sets of first data, consolidating the converted sets of first data into an assembled set of data, modifying the assembled set of data as desired, and storing the modified, assembled data set in the modified image store. The control system also assembles the two images together and stores the assembled images in the assembled image store, regions of the assembled image corresponding to previously modified regions being defined by the respective stored, assembled data set in the modified image store.

摘要： A method of compressing digital image or image-like pixel data. The method comprises carrying out the following steps on small blocks of pixels:a) determining the differences between digital values of adjacent pixels in the block to define respective link weights;b) determining a tree connecting all the pixels in the block such that the sum of the link weights in the tree is a minimum;c) dividing the tree into segments by removing links with weights greater than a threshold value, so dividing the block into segments of linked pixels;d) generating a segmented representation of the block by setting the values of all pixels in each segment to a single, respective, representational value; ande) compressing the segmented representation to generate compressed data.
