Patent number: 8885038Abstract: Provided is an apparatus and a method thereof which can detect a displacement amount of a cutting tool with respect to a workpiece with high accuracy and can correct a processing position with high accuracy. Accordingly, a turret gauge 46 is comprised of an invar body 47 and a gauge main body 48 with a different thermal expansion coefficient. A point A of the gauge main body 48 and a leading edge 47A of the invar body are imaged in a state of viewing the whole thereof at a time of an initialization and a calibration cycle (CS), and a temperature of the gauge main body 48 is detected by comparing each image data. Furthermore, the length between the point A and a point B of the gauge main body 48 at the time of the CS is obtained based on the image data. The actual length is compared with a theoretical length between the point A and the point B at a temperature of the gauge main body 48 at the time of the CS, and consideration is given to the comparison.Type: GrantFiled: April 20, 2010Date of Patent: November 11, 2014Assignee: Fuji Machine Mfg. Co., Ltd.Inventors: Tosuke Kawada, Masaki Kato, Shinji Ichino

Patent number: 8861615Abstract: A picture (1) with multiple slices (2-5) is encoded by determining a hierarchical granularity for the picture (1) defining a hierarchical level for slice border alignments. Address information allowing identification for a respective slice start is determined for at least a portion of the slices (2-5) based on the hierarchical granularity. The pixel values of the slices are encoded to generate coded slice representations (56). These coded slice representations (56) are included together with the address information into a coded picture representation (50) to which information of the hierarchical granularity is associated. The hierarchical granularity provides a flexible way of defining at which coding unit level slice borders can be present in the picture (1).Type: GrantFiled: June 29, 2011Date of Patent: October 14, 2014Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Rickard Sjoberg, Clinton Priddle

Patent number: 8861587Abstract: A picture (1) with multiple slices (2-5) is encoded by generating a coded slice representation for each of the slices. A slice flag is set to a first value for the first slice (2) in the picture (1) and corresponding slice flags of the remaining slices (3-5) are set to a second defined value. A respective slice address is generated for each remaining slice (3-5) to enable identification of the slice start position within the picture (1) for the slice. A coded picture representation (50) of the picture (1) comprises the coded slice representations, the slice addresses and the slice flags. The slice flags enable differentiation between slices (3-5) for which slice addresses are required and the slice (2) per picture (1) for which no slice address is needed to identify its slice start position.Type: GrantFiled: June 29, 2011Date of Patent: October 14, 2014Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Rickard Sjoberg, Clinton Priddle

Patent number: 8804836Abstract: A method comprising: for each target image portion to be encoded in a frame, selecting one of a set of encoding modes by optimizing a function comprising an estimate of distortion for the target image portion and a measure of bit rate required to encode the target image portion, encoding the target image portion into the encoded video stream using the selected mode. The encoded video stream is transmitted over a lossy channel. An error propagation distortion map is maintained, which comprises a plurality of error propagation distortion values mapping to respective frame partitions, the error propagation distortion values being based on previous encoding mode selections. The estimate of distortion used to select the encoding mode for each of the target image portions is based on a corresponding portion from the error propagation distortion map, and that corresponding portion is constrained to being co-located with the target image portion.Type: GrantFiled: October 17, 2011Date of Patent: August 12, 2014Assignee: SkypeInventors: Mattias Nilsson, Renat Vafin, Soren Vang Andersen

Patent number: 8797419Abstract: An image processing apparatus has: a first image processing unit for generating first image data by executing a dodging processing to an image signal obtained by picking up an image of an object; and a second image processing unit for generating second image data by executing a dodging processing having a stronger effect thereof than that of the dodging processing by the first image processing unit to the image signal, wherein the first image processing unit repeats the dodging processing a plurality of times.Type: GrantFiled: October 21, 2011Date of Patent: August 5, 2014Assignee: Canon Kabushiki KaishaInventor: Takamichi Nakata

Patent number: 8780280Abstract: First imaginary screen outer peripheral line is calculated supplementing one side that is undetected with one side of an outer peripheral line of image light that is calculated, an imaginary screen aspect ratio that is an aspect ratio of an area defined by the first imaginary screen outer peripheral line is calculated, whether the imaginary screen aspect ratio is more vertically oriented than a first ratio or not is determined. When a result of the determination of the imaginary aspect ratio is more vertically oriented than the first ratio, the imaginary screen aspect ratio is changed to second ratio that is different from the first ratio, and the one undetected side is calculated according to the second ratio, and the first imaginary screen outer peripheral line is corrected and a second imaginary screen outer peripheral line is calculated.Type: GrantFiled: September 12, 2011Date of Patent: July 15, 2014Assignee: Seiko Epson CorporationInventors: Miki Nagano, Shiki Furui

Patent number: 8773533Abstract: A detection system on detecting a light source or an object irradiated by the light source serving as an object to be photographed with high accuracy and capturing a vivid image of the object to be photographed and a signal processing method and a smoke sensor. A detection system includes an image pickup unit, a light source, a first computing unit, a second computing unit, a third computing unit, a detecting unit, and a correction instructing unit. The correction instructing unit outputs a correction instructing signal when the absolute value of a computation result A or that of a computation result B exceeds a permissible decrement. The third computing unit corrects the computation result of which absolute value is reduced between the computation results such that the decrement is less than or equal to the permissible decrement when receiving the correction instructing signal, and performs computation.Type: GrantFiled: May 13, 2010Date of Patent: July 8, 2014Assignee: Rhythm Watch Co., Ltd.Inventor: Jun Fujimori
