Patent number: 11882269Abstract: An image encoding method includes, using an image as input, determining a first mode suited to encode the image in accordance with a first processing procedure; using the image as input, determining a second mode suited to encode the image in accordance with a second processing procedure; selecting one of first mode and the second mode as a final mode; encoding the image, using the final mode; and calculating a cost of using the second mode to encode the image. The second processing procedure is implemented by a reconfigurable circuit. In the selecting, the first mode is selected when the cost calculated in the calculating is higher than a first predetermined value, and the second mode is selected when the cost is lower than or equal to the first predetermined value.Type: GrantFiled: April 15, 2021Date of Patent: January 23, 2024Assignee: SOCIONEXT INC.Inventors: Yuya Shigenobu, Masao Kitagawa

Publication number: 20140334552Abstract: An image decoding device includes: an arithmetic decoding unit performing arithmetic decoding of a bitstream to obtain a binary symbol; and a bitstream decoding control unit selecting a bitstream on which the arithmetic decoding is performed by the arithmetic decoding unit. The bitstream decoding control unit causes the arithmetic decoding unit to suspend the arithmetic decoding one bit stream and start the arithmetic decoding of another bitstream at a time point when a predetermined time period elapses, and suspend the arithmetic decoding of the other bitstream and resume the arithmetic decoding of the one bitstream at a time point when another predetermined time period elapses.Type: ApplicationFiled: July 24, 2014Publication date: November 13, 2014Inventors: Satoshi YAMAGUCHI, Masao KITAGAWA

Patent number: 8644687Abstract: In a recording apparatus (camcorders, optical disc recorders, etc.), the operator presses down priority designating buttons for designating priorities when recording input image data. An additional information generating section records and holds, in a storage section, additional information indicating priorities of data to be recorded (e.g., “low”, “intermediate”, “high”, or “highest”) which are set, depending on what priority designating button has been pressed down. If recordable remaining space in the storage section detected by the remaining amount detecting section falls below a predetermined value before the start of or during recording of data, a control section overwrites regions in order of priority of data which is stored therein, the lowest first, with data which is about to be recorded or is being recorded, based on the additional information generated by the additional information generating section.Type: GrantFiled: February 20, 2008Date of Patent: February 4, 2014Assignee: Panasonic CorporationInventors: Masao Kitagawa, Masaru Iwasa, Takeshi Yado

Patent number: 7136538Abstract: In order to reduce noise appropriately according to scaling factor and a degree of motion of an image and to suppress degradation in image quality resulting from the noise reduction to a negligible level, a noise reduction control section outputs a noise detection instruction, a noise detection threshold instruction and a filtering mode instruction based on a scale factor output from a scale factor calculating section and a motion detection result output from a motion detecting section. A mosquito noise reducing section and a blocking artifact reducing section in a noise reducing section adaptively conducts an appropriate noise reducing process using noise detection sensitivity and the number of filter taps and a filter coefficient of a smoothing filter according to these instructions.Type: GrantFiled: December 19, 2001Date of Patent: November 14, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventor: Masao Kitagawa

Patent number: 6885775Abstract: An image processing apparatus comprises a noise detection means for performing noise detection on an input image; a noise removal means for removing noise from a predetermined region of the input image, on the basis of the result of the noise detection; a counting means for obtaining the ratio of an area targeted for noise removal to the predetermined region of the input image; a statistics calculation means for obtaining the statistics on the ratios obtained by the counting means over a predetermined period of time; an image generation means for generating an image indicating the statistics; and an image composition means for superimposing the image generated by the image generation means on the image outputted from the noise removal means to generate a composite image for display. Therefore, the viewer can easily know how much noise is removed from the predetermined region of the input image, for every predetermined period of time.Type: GrantFiled: January 19, 2001Date of Patent: April 26, 2005Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Satoshi Kondo, Toshiyuki Shimada, Masahiro Honjo, Masao Kitagawa
