  • Publication number: 20150245045
    Abstract: The present invention provides an image processing apparatus capable of efficiently scheduling tasks and a control method for the same. An image processing apparatus according to an embodiment includes: a request receiving unit that receives requests from a plurality of pieces of content; a variable-length code processing unit which decodes or encodes the content; a plurality of image signal processing units executing tasks according to the requests in parallel; an estimating unit that estimates estimate time by which a process of the task is completed in each of the image signal processing units on the basis of a parameter of decoding or encoding used in the variable-length code processing unit; and a scheduling unit that schedules tasks executed by the plurality of image signal processing units on the basis of estimation time estimated by the estimating unit.

  • Publication number: 20150117549
    Abstract: The present invention is directed to reduce deterioration in parallel processing capability. In a moving-picture decoding processing apparatus, information of a first plurality of frames and a second plurality of frames is supplied from a decoding control unit to first and second decoding processing units. For decoding the information from an intermediate point to an end point of a second preceding frame by the second decoding unit in a third period, use of a result of the process of the first decoding processing unit in the third period is inhibited, and use of a result of the process of a first preceding frame by the first decoding processing unit in a second period is permitted by an end signal.

  • Publication number: 20150010082
    Abstract: To reduce noise or the like generated at a boundary of tiles introduced in a video coding method. In a motion vector detection unit, a first tile video signal and a second tile video signal included in one picture are supplied to a first detection unit and a second detection unit, and a reference image is supplied from a frame memory to the first detection unit and the second detection unit. The first detection unit performs processing, by inter prediction, on the video signal positioned on or in the vicinity of a tile boundary between a first tile and another tile among many video signals included in the first tile. In this processing, the first detection unit generates a motion vector so as to preferentially refer to the reference image included in another tile different from the first tile among the reference images read out from the frame memory.

  • Publication number: 20150003513
    Abstract: For a decoding apparatus based on H.265/HEVC with single-core or single-threaded hardware not parallelized, which executes decoding a plurality of tiles and filtering around a tile boundary, the disclosed invention is intended to reduce the frequency of access to decoded data around the boundaries between tiles stored in a frame memory for filtering such data or reduce the circuit size of a buffer that retains decoded data around the boundaries between tiles. The image decoding apparatus disclosed herein executes decoding and filtering in raster scan order across a screen independently of the sizes and positional relations of tiles. At a tile boundary, decoding proceeds to a right adjacent tile on the same row, rather than decoding coding blocks on one row down in the same tile, and filtering is also executed using decoded data of row-wise adjacent coding blocks.

  • Publication number: 20140226911
    Abstract: Signal processing including decoding and format conversion is executed on compressed image data at a high speed by simple control. A decoder decodes compressed image data in units of blocks and writes the decoded data in the blocks into a decoded data memory. A progress notification unit generates a progress signal indicating a state of progress that data is being decoded or written into the decoded data memory by the decoder and outputs the signal to a format conversion unit per picture. The format conversion unit reads out the decoded data from the decoded data memory and format-converts the data, and writes the format-converted data into a format-converted data memory. In reading out data from the decoded data memory, the format conversion unit acquires information indicating an address of decoded data readable from the decoded data memory from the progress signal.

  • Patent number: 5268731
    Abstract: The present invention relates to a wheel alignment measuring apparatus which measures the toe-in length or angle and camber angle of each tire (17) of a car.The wheel alignment measuring apparatus can be used to measure the distances to various points on the surface of the tire (17) by means of the light of a predetermined wavelength emitted from the light-emitting means (4) and to determine the toe-in angle or length and camber angle of the tire (17) based on the measured distances. In other words, such measurement can be done without any contact with the tire (17) under inspection, thus it is possible to prevent any trouble which would occur when such measurement is done in contact with the tire, such as error caused by the oscillation or the like of the tire (17).

  • Patent number: 5210589
    Abstract: In the apparatus for measuring optical-axis deflection angle of a headlight, according to the present invention, the optical-axis detecting means (3) detects the optical axis (l") of the light projected at the first location (E.sub.1) from the headlight (7), and the screen box moving mechanism (2) moves until the position of the optical axis (l") coincides with the center of the screen (9). Then, the screen box is stopped there. Next, the screen moving mechanism (10) is put into operation to move the screen (9) from the first location (E.sub.1) to the second location (E.sub.2), the optical-axis detecting means (3) detects the optical axis (l") from the light projected onto the screen (9), and the controlling means (6) makes a predetermined calculation from the information on the optical-axis position, thereby calculating a deflection angle (.alpha..sub.1, .alpha..sub.2) of the optical axis.
