Method for limiting the memory required for recording an audio, image or video file created by virtue of an apparatus in said apparatus
Method and apparatus for the digital encoding of a first raw file, the method includes: a first step of capturing the raw file, the raw file being an audio and/or image and/or video file; a second step of encoding the captured raw file into a second file, in a proprietary format (P); then, a third step for re-encoding the second file into a third file in a compatible format (C).
1. A method for digital encoding of a raw image medium, comprising:
a first step of using a digital camera to capture said raw image medium;
a second step of retrieving a quality (Qc) for restoring of a file in a compatible format (C) from a set of predefined qualities (Qc) in the compatible format (C),
wherein the set of predefined qualities (Qc) in the compatible format (C) includes at least the first quality (Qc) in the compatible format (C) and a second quality (Qc) in the compatible format (C),
wherein, prior to said second step, a respective encoding quality (Qp) in a proprietary format (P), from a plurality of different encoding qualities (Qp) in the proprietary format (P), has been associated with each quality (Qc) in the set of predefined qualities (Qc) in the compatible format (C) such that at least i) a first encoding quality (Qp) is associated with the first quality (Qc) in the compatible format (C) and ii) a second encoding quality (Qp) is associated with the second quality (Qc) in the compatible format (C);
a third step of selecting one encoding quality (Qp) of said plurality of different encoding qualities (Qp) in the proprietary format (P), wherein said selected one encoding quality (Qp) in the proprietary format (P) is associated with the quality (Qc) retrieved in the second step;
a fourth step of encoding said raw image medium into a first file, with the raw image medium encoded in the selected one encoding quality (Qp) in the proprietary format (P); then,
a fifth step of re-encoding said first file into a second file in the compatible format (C) in the quality (Qc) retrieved in the second step, in order that a file restored from the second file, using the compatible format (C), is of the quality (Qc) retrieved in the second step and the file restored is of quality equivalent to what would have been had the second file been encoded directly into the compatible format (C) according to the quality (Qc) retrieved in the second step.
2. The method according to claim 1 , wherein the raw image medium is a raw representation of image data stored in the working memory and/or the internal memory of an apparatus.
3. The method according to claim 1 , wherein the raw image medium is contained in a raw file.
4. A digital apparatus which comprises the digital camera and means for implementing the method according to claim 1 .
