Patent number: 6873745Abstract: 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.Type: GrantFiled: November 28, 2001Date of Patent: March 29, 2005Assignee: Canon Kabushiki KaishaInventors: Mitsuru Owada, Yoshitake Nagashima, Takeo Kimura

Patent number: 6108098Abstract: 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.Type: GrantFiled: December 16, 1996Date of Patent: August 22, 2000Assignee: Canon Kabushiki KaishaInventors: Mitsuru Owada, Hirofumi Nakajima, Mizuki Muramatsu
