Patent number: 7369679Abstract: A visible digital watermark is applied to output images from a computer program. Various attributes of the watermark are modified from image to image, making the watermark difficult to remove. For example, a watermark indicating “not for commercial use” can be applied to all output images from the program. Such watermarking permits full functioning demonstration versions of the computer program to be freely distributed to users while commercial use is inhibited. This is accomplished by a minimal level of intrusiveness to file sharing capabilities between a commercial version of the software and a non-commercial version of the software.Type: GrantFiled: October 24, 2006Date of Patent: May 6, 2008Assignee: NVIDIA CorporationInventors: Ian R. Ameline, Alphonse L. Lopez

Patent number: 7356190Abstract: An image area of interest in an image file can be detected by a method with a relatively light processing load by making a determination using characteristics of a quantization table. Since spatial frequency information, chromaticity information, and a quantization table are acquired for respective predetermined blocks from inputted compressed image data, and are used in combination upon searching the compression-recorded image data for an image of interest, information containing AC component information for each image data block is acquired without any advanced calculations, thus searching for the image of interest in the image file.Type: GrantFiled: June 30, 2003Date of Patent: April 8, 2008Assignee: Canon Kabushiki KaishaInventors: Shigeru Mizoguchi, Naohisa Suzuki

Patent number: 7349579Abstract: The present invention provides an image processing device, an image processing method, and an image reading method, by which encoded data can be easily generated from sub-sampled image data, without a complicated circuit or an increase in the data amount. A one-dimensional wavelet transform in a predetermined direction is omitted in stage 1, where components 1 and 2 of input image data have been sub-sampled. When coefficient data generated through such a two-dimensional wavelet transform are to be encoded, sub-bands that are not contained in the coefficient data in comparison with the coefficient data of a component 0 should be considered to have been truncated.Type: GrantFiled: September 20, 2002Date of Patent: March 25, 2008Assignee: Ricoh Company, Ltd.Inventors: Yukio Kadowaki, Mitsutaka Iwasaki, Yutaka Sato, Kazuhiro Miyazaki
