Access point pictures designated as randomly accessible positions are I pictures or P pictures. Information indicating the decoding sequence (I1, P1, B1, B2, B3, B4, P2, . . . ) of pictures functioning as access points and attribute information (picture_type) indicating whether a picture functions as an access point or is necessary for decoding of the access point following a given access point are recorded on the video information recording medium. Random access is possible even if the GOP interval is lengthened.

An image reproducing apparatus including a selection unit configured to select a still image to be reproduced, a moving image to be reproduced, and a reproduction range of the moving image from a recording medium in which a plurality of still images and moving images is recorded, and a reproduction control unit configured to perform control to sequentially reproduce the still image and the reproduction range of the moving image selected to be reproduced by the selection unit, the selection unit being configured to perform control so that both a still image and a range of a moving image in which the still image is inserted are not selected to be reproduced.

Systems and methods of transcoding video sequences for delivery in a mobile network. A source video sequence including source video frames is received and a source video frame type associated with each of the source video frames is determined based on a differential between a composition time stamp (CTS) and a decoding time stamp (DTS) associated with each of the source video frames. A frame type ratio value for the target frame-types is calculated based on a longest mini-GOP length. A target frame size of each target video frame is determined based on the frame type ratio value and a target transcoding rate, and each of the target video frames in a target video track is encoded to the target frame size to form a target video sequence.

An image processing apparatus that correctly acquires evaluation values when movie recording is performed at a fixed frame rate. A first readout unit reduces readout rows of an image pickup device, and acquires and outputs image data for movie recording from the reduced readout rows. A second readout unit acquires image data from readout rows that do not overlap with that by the first readout unit at higher rate than the first readout unit, and outputs the acquired image data simultaneously with the first readout unit. Whether a subject's state changes for both the image data acquired by the first and second readout units is determined. If it is determined that the subject's state in the image data acquired by the second readout unit is changed, a speed at which the second readout unit acquires image data is changed while the first readout unit maintains a fixed speed.

A multimedia file and methods of generating, distributing and using the multimedia file are described. Multimedia files in accordance with embodiments of the present invention can contain multiple video tracks, multiple audio tracks, multiple subtitle tracks, data that can be used to generate a menu interface to access the contents of the file and ‘meta data’ concerning the contents of the file. Multimedia files in accordance with several embodiments of the present invention also include references to video tracks, audio tracks, subtitle tracks and ‘meta data’ external to the file. One embodiment of a multimedia file in accordance with the present invention includes a series of encoded video frames and encoded menu information.

A transmission apparatus includes a reception unit and a superposition unit. The reception unit receives a parameter for setting a superposition mode in which superposition information is superposed on an image picked up by an image pickup unit from a setting apparatus. The superposition unit (i) selects, in accordance with the parameter received by the reception unit, one of a first superposition mode in which the superposition information is superposed on a predetermined position on a display screen of the picked-up image and a second superposition mode in which the superposition information is superposed on a position of the picked-up image in accordance with a change in the picked-up image displayed on the display screen and (ii) superposes the superposition information on the picked-up image.

Methods, systems, and media for generating a summarized video using frame rate modification are provided. In some embodiments, a method for editing a video is provided, the method comprising: receiving, using a hardware processor, a video file; identifying a plurality of frames at a playback frame rate from the video file; generating an edited video file by extracting a subset of the plurality of frames, wherein the extracted frames in the subset of the plurality of frames are separated by a predetermined length in the plurality of frames and wherein extracting the subset of the plurality frames modifies a frame rate of at least a portion of the video file to an effective frame rate; storing the edited video file; and presenting the edited video file at the playback frame rate.

A device for coding video data is configured to determine that a current block of video data is coded using an intra prediction mode; add an intra prediction mode of a first neighboring block of the current block to a most probable mode candidate list for the current block; add an intra prediction mode for a second neighboring block of the current block to the most probable mode candidate list for the current block; add an intra prediction mode for a third neighboring block of the current block to the most probable mode candidate list for the current block; and code the current block of video data using an intra prediction mode.

An imaging apparatus includes: an imager that captures a subject image to generate image-capturing data; a memory that temporarily stores the image-capturing data; an image processor that performs image processing on the image-capturing data to generate image data; an interface detachably connected to an external non-volatile recording medium; and a controller that records the image data in the recording medium. The controller saves the image-capturing data from the memory by writing, in the recording medium, the image-capturing data as an incomplete file being a file format defined to manage, in the recording medium, the image-capturing data as a saving state where the image processing is not completed on the image-capturing data. The controller reads the saved image-capturing data from the recording medium into the memory, causes the image processor to perform the image processing, and records obtained image data by the image processing into the recording medium.

It is determined whether an angle of view is changed or an image with an aspect ratio different from the aspect ratio of the moving image is inserted in a moving image recorded in a temporally continuous manner (system control unit), and when it is determined that an angle of view or an aspect ratio is changed, a predetermined effect is applied to the moving image (image processing unit).
