Imaging apparatus and controlling method

An image processing apparatus that handles RAW images favorably performs display when shooting and display when reproducing. The apparatus images a subject and generates RAW images, and reduces the RAW images and generates reduced RAW images. The RAW images and reduced RAW images are recorded in a recording medium. When shooting, the reduced RAW images are subjected to developing processing for display, and when reproducing, the reduced raw images recorded in the recording medium are acquired and subjected to developing processing in accordance with instructions to reproduce, and each is used for display.

Image processing apparatus and image processing method for handling raw images

An image processing apparatus that handles RAW images efficiently performs editing for reproducing RAW images. The apparatus compresses each of RAW images and reduced RAW images which are reduced from the RAW images, and records each in a recording medium. When editing, the image processing apparatus communicates with an external apparatus and transmits the reduced RAW images stored in the recording medium to the external apparatus, and causes the external apparatus to perform editing processing of the reduced images. Further, the image processing apparatus uses editing information representing the content of editing processing from the external apparatus to execute editing of the RAW image corresponding to the reduced RAW image on which the editing processing has been performed, by referencing the editing information.

Image processing apparatus and image processing method

An image processing apparatus is configured to capture an object image, generate a RAW image, perform simple development on the RAW image during the image capturing operation, and store not only the developed image but also the RAW image. In a predetermined interval, in an idle state, or in predetermined enlargement processing, the image processing apparatus reads a RAW file stored in a storage medium and performs high-quality image development to generate an image having higher image quality than that obtained by the simple development. If development processing has been completed by a high-quality image development unit, the image processing apparatus replaces the image obtained by the simple development with the image obtained by the high-quality image development and reproduces the image obtained by the high-quality image development.

Image processing apparatus and image processing method for handling a raw image, of a moving image or a still image

An imaging apparatus is configured to capture an object image, generate a RAW image, perform simple development on the RAW image during the image capturing operation, and store not only the developed image but also the RAW image in a storage medium. If the imaging apparatus displays an image during the image capturing operation and immediately after the image capturing operation, the imaging apparatus displays the image processed by the simple development. When the imaging apparatus completes processing of high-quality image development, the imaging apparatus replaces the image processed by the simple development with the image processed by the high-quality image development and displays the image processed by the high-quality image development.

Imaging apparatus and imaging apparatus control method

When encoding moving images using an encoding scheme in which a termination process is performed, controlling so that a picture to be encoded after a picture whose encoding has been forcibly terminated does not refer to the picture whose encoding has been forcibly terminated. By so doing, encoding using a reference picture with low correlation is suppressed and encoding efficiency can be improved.

The number of times of processing to increment the number of reserved bits in arithmetic coding processing is reduced. For this purpose, upon inputting a binary symbol, a zone is divided into two zones at a ratio between occurrence probabilities of MPS and LPS, and one of the divided zones is selected according to the input symbol. When the length of the selected zone is shorter than a predetermined length, normalization is performed. Then it is determined whether or not a threshold for determining a decimal place of interest exists within the zone of interest. When the threshold exists within the zone of interest, the number of reserved bits is incremented by one. When the threshold exists without the zone, 1-bit data determined based on a relative position between the zone of interest and the threshold is outputted, bit data corresponding to the number of reserved bits is determined and outputted, and the number of reserved bits is cleared to zero.

Video recording/reproducing apparatus and video recording/reproducing method

A signal processing apparatus includes a conversion unit, an encoding unit, and a control unit. The conversion unit converts first moving image data having a first frame rate into second moving image data having a second frame rate by inserting a new frame into the first moving image data having the first frame rate at predetermined timing. The encoding unit encodes the second moving image data having the second frame rate by selectively using intra-frame encoding and inter-frame prediction encoding. The encoding unit classifies each frame of the second moving image data as a first frame type which is not referred to in the inter-frame prediction encoding and a second frame type which is referred to in the inter-frame prediction encoding, and the encoding unit encodes the second moving image data according to the classification result. The control unit controls the encoding unit such that the frame inserted by the conversion unit among the second moving image data is encoded by classifying the inserted frame as a particular frame type.

Image processing apparatus

An imaging apparatus for encoding a moving picture signal output by imaging means using intraframe encoding and interframe encoding. An encoded image signal which includes picture groups comprising n frames of an image signal including intraframe-encoded pictures and interframe-encoded pictures is generated. An instruction starts a recording of the encoded image signal. The encoded image signal is transmitted to an external device while the signal is in an encoded state and the encoded image signal is transmitted to an external device while the encoded image signal is not being recorded. Upon detection of the instruction during transmission of the encoded image signal to the external device, recording of the encoded image signal starts, from the leading end of a picture group that contains a frame, corresponding to the instruction.

An image processing apparatus enables smooth joint recording between 2 video coded streams without re-encoding by generating and inserting a dummy stream to maintain periodicity of phase information therebetween. A 2-3 pulldown unitconverts moving image data having a frame rate of 24 frames per 1 second, by periodically generating 2-field picture data and 3-field picture data from respective frames, to data having 60 fields per 1 second. An MPEG unitcompression-encodes the converted data. At this time, phase information of fields included in the respective pictures are added. A stream information detection unitdetects the phase information of a field included in a head picture. On the other hand, a join position information detection unitdetects the phase information of a field included in a rear end of a compressed coded stream already recorded on a recording medium. A connection stream generation unitgenerates a connection stream to maintain phase conformity upon connection of the two streams based on the phase information. Then the streams are recorded, in a status where the connection stream is inserted therebetween, on the recording medium.
