Patent Number Title Of Patent Date Issued
8090209 Image coding device, digital still camera, digital camcorder, imaging device, and image coding m January 3, 2012
Coding processing performed by an image coding device (100) includes: processing (S133) of performing coding by leaving surplus bit(s), when the digit number B of binary data of the difference value between (a) a value of a to-be-coded pixel and (b) a prediction value is smaller than
7978198 Image data transfer method, image processing device, and imaging system July 12, 2011
An image data transfer method including the steps of: (a) reading pixel data of a two-dimensional image stored in a first image storage and having a plurality of pixels, the position of each of the pixels being represented by coordinates of first and second directions, the pixel data
7929777 Variable length decoding device, variable length decoding method and image capturing system April 19, 2011
A first data buffer stores LEVEL representing the size of a non-zero coefficient value of the variable length coded/run length coded data input from the outside. A write controller writes the LEVEL to the first data buffer in decoded order. An initial address calculator calculates th
7844123 Orthogonal transformation apparatus and imaging system November 30, 2010
A one-dimensional orthogonal transformation device group constituted with a plurality of one-dimensional orthogonal transformation devices performs one-dimensional orthogonal transformation to the pixel data of one block that is inputted to an input device. A memory device stores the
7764845 Signal processing method and device and video system July 27, 2010
In a signal processing device for performing inverse orthogonal transform for a combination of orthogonal transform coefficients obtained by orthogonal-transforming a signal, a pixel signal value for a combination of orthogonal transform coefficients high in appearance is stored in a
7542612 Signal processing method and signal processing device June 2, 2009
A storage unit which stores n pieces of data is formed by m memories (m.noteq.n). The n pieces of data are sorted into the memories such that the n pieces of data can be read in parallel no matter which read scan mode is selected among a plurality of read scan modes. With this struct
7292634 Image coding method and apparatus November 6, 2007
A motion detection block includes a wavelet transform section which receives a current image I1 and a reference image I2 as inputs. The motion detection section detects a motion vector using size-reduced images RI1 and RI2 generated by transform in the wavelet transform section. Thus
7248191 Variable-length coding method, variable-length coding device and imaging system July 24, 2007
A VLC mode judgment section performs judgment on whether or not a received group (Last, Run, Level) exists in a VLC table and then performs judgment on which one of a first escape mode, a second escape more and a third escape mode is suitable. According to a judgment result of the VLC mo
6885756 APPARATUS AND METHOD FOR EMBEDDING WATERMARK INFORMATION IN COMPRESSED IMAGE DATA, AND APPARATUS April 26, 2005
A variable length decoding section extracts a codeword and an additional bit or bits corresponding to the codeword from compressed image data based on a code table. An embedding section embeds watermark information in a prescribed bit of the additional bits extracted by the variable leng
6388588 Encoding device and encoding method for changing code amount of compressed image data May 14, 2002
Compressed image data from a code memory is separated into quantization step values, code table information and variable-length codes. The variable-length codes are each decoded into a run length, a size and an additional bit string and written into a size memory. A size conversion s
