    Abstract: Opportunistic image quality improvement in a digital camera. In a digital camera having a picture memory of fixed size for storing a predetermined number of pictures, raw image data is compressed to form primary and auxiliary data sets. The primary data set allows the image to be reconstructed at a first quality level. The primary and auxiliary data sets combined allow the reconstruction of the image at a higher quality level. As images are taken and processed, if sufficient storage space exists in the picture memory, both primary and auxiliary data sets are stored. This continues until the memory is full of primary and auxiliary data sets. Once the memory is full, as more images are taken and stored, the space used by auxiliary data sets is reclaimed for use by primary data sets, and the auxiliary data sets are not stored.

    Abstract: A desired area, a desired resolution of the desired area, and a desired reduction ratio of an area other than the desired area are specified. An image data of the desired area is extracted from an image data of a document read at the desired resolution. A changed image data is created by changing the image data of the document based on the desired reduction ratio. The image data of the desired area and the changed image data are subjected to multi-page filing and saved as one file.

    Abstract: The invention provides a mode switching method in a digital image acquisition apparatus with a first button for taking pictures and a second button for mode switching. Snapshot modes and a viewing mode are provided. A snapshot parameter is for recording whether the apparatus is currently used for taking pictures. Each time when the apparatus is used for taking pictures via the first button, the snapshot parameter is recorded as a snapshot status. A mode parameter is for recording which mode the apparatus is currently situated. Each time when the apparatus is used for mode switching via the second button, the mode parameter is recorded as a corresponding mode status. When the apparatus performs mode switching via the second button, if the snapshot parameter is at the same time recorded as the snapshot status, the apparatus is switched directly to the viewing mode in irrespective to its original snapshot mode.

    Abstract: In an image processing method and apparatus for decoding and displaying input encoded data, the upper limit value of the data size to be stored in a memory that stores fragmented encoded data which form image data is set. It is checked based on the data size already stored in that memory, the upper limit value, and the data size of the input encoded data, if that input encoded data can be stored in the memory. If it is determined that the input encoded data cannot be stored in the memory, a region to be deleted in the image data of the data stored in the memory is determined. Data included in the determined region to be deleted is deleted for each fragmented data as a unit. If it is determined that the input encoded data can be stored in the memory, or after the data is deleted, the input encoded data is stored in the memory.
