A recording apparatus is disclosed. The recording apparatus includes a data input portion configured to input data, a first moving image signal recording portion configured to record, based on the input data, a first moving image signal having a first image quality attribute, a condition detector configured to detect that the input data satisfies a predetermined condition during recording of the first moving image signal, and a second moving image signal recorder configured to record, based on the input data, a second moving image signal having a second image quality attribute when the condition detector detects that the input data satisfies the predetermined condition.

An image processing apparatus includes a storage storing images received from at least one camera, an image analyzer analyzing the images received from the at least one camera, separating an object, for which an event occurred, from a background, and extracting object properties information, a database storing the object properties information extracted with respect to each of the at least one camera, a search condition setter setting a search condition, a search engine searching the database for the object properties information matching the search condition, and obtaining image frames including the object properties information found from the storage, and a file generator generating a single image file by synthesizing the image frames.

Embodiments provide a video camera that can be configured to compress video data in a manner that achieves a targeted output size in a computationally efficient manner. The video compression systems and methods can be used with DCT-based compression standards to include a rate control aspect. The rate controlled video compression methods can be configured to compress video data in, real time and/or using a single pass. During compression of video data, the video compression systems and methods can modify compression parameters to achieve a targeted file size while maintaining relatively high visual quality of the compressed images.

A camera system, a camera body, and a communication method capable of satisfactorily acquiring lens information necessary for image processing or the like for a frame of a video from an interchangeable lens are provided. Three-wire serial communication is performed in which a request signal is transmitted to the interchangeable lens in synchronization with a synchronization signal (VSYNC) of an imaging element in a video recording mode, and a response signal is received from the interchangeable lens. In a communication mode in the video recording mode, the number of transmissions of a first request signal relating to acquisition of lens information such as a focus position, a diaphragm value, and a zoom position is limited. Accordingly, communication other than communication relating to acquisition of lens information can be performed in a period of one frame.

An automatic playback overshoot correction system predicts the position in the program material where the user expects to be when the user stops the fast forward progression of the program material. The system determines the position where the program material was stopped and transitions to the new mode that the user selected, starting at the stopped position with an overshoot correction factor subtracted from it. The system uses a prediction method to correctly place the user within the program upon transition out of fast forward mode and determines if the speed of the fast forward mode and then automatically subtracts a time multiple to the frame where the transition was detected and positions the user at the correct frame. The time multiple is fine tuned if the user is consistently correcting after the fast forward mode stops.

Embodiments described herein provide systems and methods for managing quality level of video transmission and storage. In a particular embodiment, a method provides receiving a video at a received quality level in a video storage system and determining a characteristic of the video. The method further provides determining whether the characteristic satisfies a criteria and, if the characteristic satisfies the criteria, storing the video at a quality level associated with the criteria.

Systems and methods for enabling playback control functions of a media player are disclosed. For example, a user of a client device receiving streaming playback of a video stream may perform rewind and fast forward control functions. The client device may implement these playback control functions by retrieving an enhanced playback segment. Using the enhanced playback segment, the media player may display selected frames at a predetermined interval while maintaining a visual cadence that is pleasing to a viewer. In the described embodiments, a client device may render a video stream, receive a command to control a fast forward or rewind playback mode for the video stream, and retrieve, from a distribution server or associated edge cache, one or more enhanced playback segments adapted to implement the user command.

A method may include generating one or more control signals configured to control a velocity of an image sensing system based on a rate of recording pixels frames in the image sensing system. In some embodiments, the method may alternatively or additionally include generating one or more control signals configured to control the rate of recording in the image sensing system based on the velocity of the image sensing system. In some embodiments, a portion of image pixel data for a pixel frame may be output for transmission to a remote receiver. In some embodiments, the output data may include a recently recorded image data pixel for those surface resolution cells for which there is no currently stored reference image data pixel of a previously recorded pixel frame that is the same or is different by less than a threshold amount as the recently recorded image data pixel.

An image processing apparatus that records a moving image used for generating a still image by a generation unit, comprises: a correction amount calculation unit configured to calculate, for each frame of the moving image, a correction amount for correction of a rolling shutter distortion of an image signal based on a shake amount detected by a camera shake amount detection unit; and a recording unit configured to record the correction amount in association with an image for each frame of the moving image, wherein the generation unit corrects an image of a selected frame from among the images of the frames based on the associated correction amount, and generates a still image.

A system is provided for providing a trickplay operation using a digital video recorder (DVR) when the video includes Broadcom Transport Packets (BTPs) designed for MPEG-2, but in an MPEG-4 video steam. In a first embodiment, to enable trickplay to function properly with MPEG-4 video, the BTP descriptors included with each group of data frames are disabled so that a single descriptor provided without BTPs that would otherwise be provided in MPEG-4 is all that remains. In a second embodiment, the 5 descriptors for MPEG-4 are combined into a single descriptor. In a third embodiment, the pace of decoding of the MPEG-4 descriptors is increased so that the speed of encoding all the 5 descriptors is comparable to the pace of decoding a single MPEG-2 descriptor.
