  • Publication number: 20180233174
    Abstract: A display control apparatus capable of performing time-line display of a moving image including a section recorded at a different recording speed from the real-time recording speed, at time intervals designated by a user. Frames are extracted from a moving image at time intervals set by a user to display the extracted frames in a line. When a moving image includes a first section recorded at a recording frame rate which is the same as a reproduction frame rate, and a second section recorded at a frame rate different from the reproduction frame rate, frames are extracted from the first section at a first frame interval, and from the second section at a second frame interval different from the first frame interval. The frames extracted from the first section and the second section, respectively, are displayed in a line.

  • Patent number: 9889393
    Abstract: A plurality of hollow filter sheets have a suction pipe inserted therethrough to be stacked with a ring-shaped packing clamped therebetween. Therefore, a gap between the hollow filter sheet and the suction pipe is watertightly sealed. In the hollow filter sheet, a hollow portion is provided between two filters, and then a spacer with a surface having pits and projections is provided in the hollow portion. A narrow passage space allowing liquid to pass through is provided between the filter and the spacer by pressing the two filters against surfaces of the spacer with the packings and causing the filters to be deformed into a shape according to the surfaces of the spacer. The narrow passage space is smaller than a drainage space between the filters and the spacer that are not clamped by the packings.
