There is provided a recording apparatus that records data to a memory card, comprising: a control unit configured to repeatedly transmit a data recording instruction that includes information designating recording target data and a recording destination to the memory card which manages a memory for data recording in the memory card as a plurality of recording areas and which can execute data recording with a guaranteed minimum recording speed in units of recording areas, wherein when transmitting a first data recording instruction that designates a start portion of a first recording area as a recording destination, the control unit requests the memory card to execute data recording with the guaranteed minimum recording speed with respect to the first recording area by including a speed guarantee request in the first data recording instruction.

Recording apparatus, recording method, storage medium, and memory card

An image recording playback apparatus which, when recording moving image data, performs image capture at high-speed read time Dt, records all the captured images, and records a playback rate Ft (Vt), the read time Dt and image valid time St, with the image data, on a recording medium. Then upon playback of moving image data, the image recording playback apparatus plays back the recorded image data within the image valid time St in accordance with the playback rate. The image recording playback apparatus having this configuration can perform playback intended by a user. Further, when sharpness is to be changed, a playback image with different sharpness can be obtained by changing the image valid time St upon playback.

Image recording apparatus and image playback apparatus

An imaging apparatus includes a signal processing unit that generates moving image data and still image data using image data output from an imaging unit, a moving image coding unit that encodes the moving image data, a still image coding unit that encodes the still image data, a recording unit that records the coded moving and still image data on a recording medium, a setting unit that sets a data rate of the coded moving image data, and a control unit that controls the moving and still image coding units. The control unit controls the moving image coding unit based on the set data rate to adjust the data rate of the moving image data and the still image coding unit based on the set data rate and a recording data rate of the recording medium to adjust an amount of the still image data.

Imaging apparatus having improved usability when moving images and still images are recorded

An image encoding apparatus for performing inter-frame encoding of moving image data is provided. The apparatus refers to a block within a frame other than a current frame to generate a first prediction image of a block to be encoded within the current frame, and performs prediction encoding using the first prediction image. The apparatus sets areas at set positions that differ from each other at least between mutually adjacent frames; and determines whether the block to be encoded within the current frame belongs to the area set with respect to the current frame. When the block to be encoded has been determined to belong to the area, the first prediction image is generated, with regard to the block to be encoded, upon referring to a frame that is decodable on its own and, in terms of time, is situated ahead of and closest to the frame to be encoded.

Image encoding apparatus, method of controlling therefor, and program

An object of this invention is to suppress discontinuity of a moving image as much as possible. In order to achieve this object, an image reproduction apparatus includes a buffer which temporarily stores an encoded image data stream, a buffer size setting circuit which sets the storage size of the buffer, a decoding time calculation circuit which calculates a decoding time at which the encoded image data stream is output from the buffer to a decoder, and a control circuit which controls to set the storage size of the buffer to at least twice the maximum value of a storage size required by an encoded data stream reproducible by the image reproduction apparatus, start fetching a second encoded image data stream in the buffer immediately after fetch of a first encoded image data stream in the buffer is ended, and calculate the decoding time of the second image data stream on the basis of a time when fetch of the first image data stream in the buffer is ended.

Image reproduction apparatus, control method thereof, program and storage medium
