Patent number: 8239578Abstract: Method of transferring digital data between a client device and a server device on a communication network, said method being implemented within said server device and comprising: i) coming from the client device, receiving a request in markup format for the delivery of a digital object or part of a chosen digital object, ii) obtaining in the communication network a representation of the object requested, iii) checking whether the representation of the object thus obtained corresponds to a data compression format of the progressive type, iv) in the event of a positive check, dividing the digital object into a plurality of sub-parts, to each sub-part there being allocated a high priority rank defined according to at least one chosen criterion, and v) sending to the client device a response in markup format comprising the sub-parts of the digital object in binary format and associated priority ranks in markup format.Type: GrantFiled: February 3, 2006Date of Patent: August 7, 2012Assignee: Canon Kabushiki KaishaInventors: Franck Denoual, Jeanne Guillou

Patent number: 7570825Abstract: A method relates to the of determining a data configuration of a digital signal of an image, the signal having undergone at least one spatio-frequential transformation in at least one resolution level. The method includes determining and configuring steps. The determining step determines at least one minimum rate reduction (Dmin) as a proportion of the total data rate of at least one resolution level of the signal, as a function of a quality mode desired for the signal. The configuring step configures the data of the signal in at least one quality layer defined for at least one resolution level of the signal such that the at least one quality layer so defined corresponds to a given visual quality of the signal, the data making up that at least one quality layer being obtained by a reduction (D) of the total rate of the data of the at least one resolution level of the signal which is greater than or equal to the minimum reduction (Dmin).Type: GrantFiled: December 11, 2003Date of Patent: August 4, 2009Assignee: Canon Kabushiki KaishaInventors: Jeanne Guillou, Patrice Onno

Patent number: 7460720Abstract: This method of defining qualities for a digital image signal encoded beforehand consists of defining a predetermined number of quality modes each corresponding to at least one decoding parameter of the digital signal, this definition being made on the basis of rate information provided via a graphical interface and quality perception information provided via the visualization of the decoded digital signal.Type: GrantFiled: March 12, 2004Date of Patent: December 2, 2008Assignee: Canon Kabushiki KaishaInventors: Jeanne Guillou, Maryline Clare

Patent number: 7260264Abstract: A method of transcoding a digital signal encoded according to a first encoding mode into a digital signal encoded according to a second encoding mode, the second encoding mode comprising a bit rate-distortion allocation of the encoded digital signal. The method comprises the steps of obtaining at least a first parameter of encoding the signal according to the first mode, obtaining at least a second parameter from an at least partial encoding of the signal according to the second mode, and selecting a bit rate-distortion allocation mode for the encoding of the signal according to the second mode, as a function of the first and second parameters.Type: GrantFiled: July 24, 2003Date of Patent: August 21, 2007Assignee: Canon Kabushiki KaishaInventors: Jeanne Guillou, Patrice Onno

Publication number: 20060171702Abstract: A method of recording images composing a panorama in a digital image capture apparatus includes the step of capturing at least one digital image of the panorama, storing the at least one captured image, and inserting information of the at least one captured digital image in a composition descriptor of the panorama including information relating to the different images composing the panorama. The inserted information includes the position of the at least one captured digital image, that position having the coordinates of at least one predefined point of the at least one captured digital image in the panorama and, for at least one region of overlap between at least the captured digital image and at least one adjacent digital image of the panorama, at least one dimension of the region of overlap.Type: ApplicationFiled: January 31, 2006Publication date: August 3, 2006Applicant: CANON KABUSHIKI KAISHAInventors: Jeanne Guillou, Patrice Onno
