  • Patent number: 10003767
    Abstract: 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.

  • Patent number: 9894270
    Abstract: 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.

  • Patent number: 9300971
    Abstract: 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.

  • Patent number: 8588540
    Abstract: 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.

  • Patent number: 7756203
    Abstract: 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.

  • Patent number: 7693400
    Abstract: 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.
