  • Patent number: 6873745
    Abstract: The subject matter of the invention is to add information to image data of multicolor image and monochromatic image. An image processing apparatus capable of adding information on raw data performs a dispersion conversion on the spectrum of the additional information by multiplying a code sequence of the PN sequence generator 114 by the additional data which is inputted from the input terminal 111 and converted into serial data in P/S converter 112. At this time, the data sequence transmitted from the image signal processor 102 to the printer engine 107 is converted by the scan converter 109 to correspond to the spatial axis for desperation. The converted data sequence is added to the output from the adder 113 by the adder 110, and reconverted to the original scan by the scan inverter 115.

  • Patent number: 6636699
    Abstract: A focus detection device includes a plurality of light receiving sensors having sensitivity characteristics such that their respective visible spectra have different wavelength regions, a focus detection circuit which performs focus detection based on an output of any one of the light receiving sensors, and a determination circuit which determines whether or not the focus detection result is appropriate. If the determination circuit determines that the result is not appropriate, the focus detection circuit performs focus detection based on the output of another light receiving sensor.

  • Patent number: 6108098
    Abstract: Color space conversion and correction processing are performed on inputted R, G and B image data 1 by an RF converter 2, and Y, M, C and K image data 3 is obtained. In the case where Y, M, C and K or Y, M and C image data is directly inputted, the RF converter 2 is passed through without being processed. Inverse processing is performed on the Y, M, C and K image data 3 by a conversion table 6 where a conversion table is set in advance, and the original R, G and B image data is obtained. An image recognition circuit 7 recognizes an image on the basis of the R, G and B image data outputted from the conversion table 6. By virtue of the above process, when an image of a specified document is to be recognized, image recognition can be performed with high precision on the basis of R, G and B image data where inverse conversion has been performed on Y, M, C and K image data or Y, M and C image data.

  • Patent number: 5907661
    Abstract: An apparatus for recording video data by forming many tracks on a recording medium and/or for reproducing the video data from the tracks is provided with a memory which is arranged to have recording video data or reproduced video data supplied thereto. The apparatus detects the picture change-over portion of the video data obtained within the tracks and controls, in accordance with the detected position, an offset degree between the writing and reading addresses of the memory.
