    摘要： The invention relates to a method for converting a standard dynamic range (SDR) sequence into a high dynamic range (HDR) sequence. It comprises:
    - determining (S1) successive shots in the SDR sequence by cut detection,
    -detecting (S2) if the SDR sequence comprises a subsequence of at least two successive short shots having a duration lower than D 1 , said subsequence comprising at least one bright shot having a luminance and a size greater than L 1 and SZ 1 respectively,
    -mapping (S3) the luminance range of bright shots of the detected subsequence from the low dynamic range to a first high dynamic range and mapping the other shots of the SDR sequence from the standard dynamic range to a second high dynamic range in order to generate the HDR sequence, the first high dynamic range having a maximal value L max1 lower than that of the second high dynamic range L max2 .

    摘要： There are provided a plurality of methods for detecting a scene change in a streamed video, the streamed video comprising a series of pictures. An example method comprises calculating, for a plurality of positions, a difference between the costs of coding macro-blocks at the same position in successive pictures. The method further comprises identifying a new scene when the sum of the differences for a plurality of positions meets a threshold criterion. There is further provided a method of determining the perceptual impact of a packet loss on a streamed video the method comprising: identifying a packet loss; and determining if the lost packet contained information relating to a picture at the start of a new scene, wherein a new scene is detected using one of the methods disclosed herein.

    摘要： An endoscope apparatus includes a focus control section (347) that performs a focus control process that controls a position of a focus lens (220) to an in-focus position based on an in-focus evaluation value, the focus lens (220) being included in an optical system that forms an image of a captured image that is acquired by an imaging section (200), and the in-focus evaluation value being calculated from a first area within the captured image, and a change-in-scene detection section (346) that detects whether or not a change in scene has occurred from a second area that includes an area that differs from the first area, wherein the focus control section (347) is set to a standby state when the position of the focus lens (220) has been controlled to the in-focus position, and resumes the focus control process when a change in scene has been detected when the focus control section (347) is set to the standby state.
