Publication number: 20140044191Abstract: The decoder operable: to process the encoded input data to extract therefrom header information indicative of encoded data pertaining to blocks and/or packets included in the encoded input data, the header information including data indicative of one or more transformations employed to encode and compress original block and/or packet data for inclusion as the encoded data pertaining to the blocks and/or packets; to prepare a data field in a data storage arrangement for receiving decoded block and/or packet content; to retrieve information describing the one or more transformations and then applying an inverse of the one or more transformation for decoding the encoded and compressed original block and/or packet data to generate corresponding decoded block and/or packet content for populating said data field; and when the encoded input data has been at least partially decoded, to output data from the data field as the decoded output data.Type: ApplicationFiled: August 13, 2012Publication date: February 13, 2014Applicant: Gurulogic Microsystems OyInventors: Ossi Kalevo, Tuomas Kärkkäinen

Patent number: 8649427Abstract: The invention relates to an image processor configured to: receive an image, take area-specific samples (11) of the image information of the area and calculate (12) a reference value (REF) on the basis of the samples; store into a memory (16) or to transmit (17) the reference value (REF) calculated for an area and the area identifier (ALUE) area-specifically; check (13) whether the reference value (REF) obtained as a result of the calculation and the image information (INF) corresponding to it have already been stored in the memory (16) or transmitted (15); and to store into the memory (16) or to transmit (15) the calculated reference value (REF) and the corresponding image information (INF), if the reference value (REF) and the corresponding image information (INF) have not been stored into the memory or transmitted previously.Type: GrantFiled: June 16, 2010Date of Patent: February 11, 2014Assignee: Gurulogic Microsystems OyInventor: Tuomas Kärkkäinen

Patent number: 8615137Abstract: The invention relates to a pattern recognizer, which, in order to recognize the pattern fast and with lowest possible computing power, comprises a memory (12) for storing area-specific reference values (REF) calculated on the basis of image information of image areas containing parts of the pattern to be recognized, and a processor (14) that is configured to divide (15) a received image into areas, to calculate (16) reference values (REF) area-specifically on the basis of the image information of said areas, to compare (17) the calculated reference values (REF) with the reference values (REF) stored in the memory (12) and to indicate (18) that the pattern is recognized, in case in the received image there is found a part consisting of adjacent areas, where the reference values (REF) of the areas correspond, with sufficient accuracy, to the reference values (REF) stored in the memory (12).Type: GrantFiled: July 6, 2010Date of Patent: December 24, 2013Assignee: Gurulogic Microsystems OyInventor: Tuomas Kärkkäinen

Publication number: 20130315307Abstract: A processor is configured to receive input data, divide an individual frame into blocks, compare the blocks with corresponding blocks of a first prediction frame for and identify changed blocks. In order to obtain an efficient solution for processing and reproducing frames, the processor is configured to include in generated intermediate data the blocks identified as changed blocks, and generate a change indicator indicating the positions in the individual frame of the identified changed blocks and identified unchanged blocks.Type: ApplicationFiled: August 5, 2013Publication date: November 28, 2013Applicant: GURULOGIC MICROSYSTEMS OYInventors: Tuomas KARKKAINEN, Ossi KALEVO

Publication number: 20120219065Abstract: The present invention relates to an image processor that is configured to compare a single frame included in the received signal with a preceding processed frame so as to detect changes. In order to enable the image being compressed in as compact a format as possible, the processor is configured to detect changes by dividing the pixels of a single frame into movement blocks and to detect the movement block as changed if in said movement block there is a given number of pixels whose colour value change as compared with the corresponding pixels of the preceding processed frame exceeds a predetermined threshold, to exchange the colour values of the pixels of the unchanged movement blocks in the frame under process for predetermined values and to generate a signal that indicates the changes.Type: ApplicationFiled: May 1, 2012Publication date: August 30, 2012Applicant: Gurulogic Microsystems OyInventors: Tuomas Kärkkäinen, Ossi Kalevo

Publication number: 20120183075Abstract: The present invention relates to a video image processor that is configured to compare a single frame included in the received video signal with a preceding processed frame so as to detect changes. In order to enable the video being compressed in as compact a format as possible the processor is configured to detect changes by dividing the pixels of a single frame into movement blocks and to detect the movement block as changed if in said movement block there is a given number of pixels whose colour value change as compared with the corresponding pixels of the preceding processed frame exceeds a predetermined threshold, to exchange the colour values of the pixels of the unchanged movement blocks in the frame under process for predetermined values and to generate a signal that indicates the changes.Type: ApplicationFiled: March 27, 2012Publication date: July 19, 2012Applicant: Gurulogic Microsystems OyInventor: Tuomas Kärkkäinen
