  • Publication number: 20180246525
    Abstract: A control system includes: a moving object; and a control apparatus. The moving object is configured to: determine a face direction based on whether or not a face image of the human exists; and control the movement apparatus so that the moving object moves in accordance with path information. The control apparatus is configured to: detect a position of the human and the moving object in the area; calculate, based on the position of the human and the moving object, and the face direction, the path information for allowing the moving object to arrive at any one of a position within a predetermined range from the human and in a field of view of the human and a position within the predetermined range from the human and outside the field of view of the human; and transmit the path information to the moving object.

  • Patent number: 8774552
    Abstract: In order to transfer an image encoded at a high compression rate and suitably increase the resolution of the transferred image, it is provided an image transfer system, comprising: an image transmission unit that transmits an image; and an image reception unit that receives the image transmitted from the image transmission unit. The image transmission unit scales down the image, and transmits the scaled-down image to the image reception unit. The image reception unit calculates an angle between a line displayed in the image transmitted from the image transmission unit and a horizontal direction of the image in correspondence with pixels included in the image, scales up the image transmitted from the image transmission unit, and removes an aliasing component of the scaled-up image based on the calculated angle.

  • Patent number: 8483279
    Abstract: A moving image processor includes a first and a second moving image processing unit which are able to perform parallel operation, and a data transfer unit having a first buffer and a second buffer. The first moving image processing unit processes macroblocks MB00, - - - , of one row of one image sequentially, and the second moving image processing unit processes macroblocks MB10, - - - , of the next row sequentially. The first and the second moving image processors include a first and a second deblocking filters, respectively. Operation timing of the second filter is delayed by the processing time of two macroblocks, compared with operation timing of the first filter. The processing results of the first filter and the second filter are transferred to an external memory via the first buffer and the second buffer of the transfer unit.

  • Publication number: 20120301012
    Abstract: When super-resolution processing is applied to an entire screen image at the same intensity, a blur contained in an input image is uniformly reduced over the entire screen image. Therefore, the screen image may be seen differently from when it is naturally seen. As one of methods for addressing the problem, there is such a method that: when a first image for a left eye and a second image for a right eye are inputted, each of parameters concerning image-quality correction is determined based on a magnitude of a positional deviation between associated pixels in the first image and second image respectively; and the parameters are used to perform image-quality correction processing for adjusting a sense of depth of an image.

  • Publication number: 20100211623
    Abstract: The present invention is directed to improve efficiency of a filter processing on an image. A filter processing module includes a filter circuit and a control circuit. The filter circuit includes: a first register capable of storing data; a first arithmetic logic unit capable of executing a first filter processing on the basis of output data of the first register; a second register capable of storing a result of the arithmetic operation of the first arithmetic logic unit; and a second arithmetic logic unit capable of executing a second filter processing on the basis of output data of the second register. The control circuit adjusts the number of pieces of data which is input per cycle in the first register in accordance with the number of taps in the first filter processing, size of an execution result of the first filter processing, and the number of second arithmetic logic units, thereby promptly completing the first filter processing.

  • Publication number: 20090129749
    Abstract: In a video recorder, closed caption sentence data is outputted by analyzing digital broadcasting data including closed caption information. Index data is generated on the basis of a feature extraction rule and the effectiveness of an appearing keyword by analyzing closed caption sentence data. Closed caption feature data including a type of a closed caption sentence and a display time is generated by analyzing a closed caption ES (Elementary Stream). The broadcasting data is stored as record data, the closed caption feature data is analyzed, chapter data for reproducing a program is generated by a chapter designated by the user, and the chapter data is outputted to a storage. In the case of recording and reproducing the digital broadcasting program, it is possible to perform both the reproduction by the optimal index using the closed caption and the reproduction by the keyword voluntarily inputted by the user.

  • Publication number: 20080118233
    Abstract: A telop recognition method is provided which, during a telop recognition operation, can correct an error, if any, in the recognition operation without loading dictionaries of unnecessary character type into memory and which, when the telop recognition is performed again, does not have to initiate the telop recognition operation from the start. The telop area extraction unit and the character extraction unit are operated to generate character image data, which is temporarily stored. The dictionary data selection unit selects dictionary data corresponding to a program category. By using the character image data and the dictionary data, a character recognition operation is executed to produce candidate character strings. The telop information generation unit processes the candidate character strings to generate telop information.
