    Abstract: Disclosed is a processor-implemented method for processing image data comprising a plurality of pixels and system for performing the method. The method includes the following acts: determining at least one type of data represented by the plurality of pixels, determining, for each type of data, a number of pixels from the image data representing that type of data in the image data, and determining a compression scheme for compressing the image data based on a relative or absolute amount of each type of data in accordance with a predetermined scheme. The type of data may be determined by received input (e.g., user selected type and compression quality) or by analyzing its pixels and comparing it to thresholds. Basing the compression technique on the data type allows for better selection of a compression technique (e.g., MRC or JPEG), and thus greater image quality, compression ratios, and file size.

    Abstract: 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.

    Abstract: Images captured in a digital form are stored in a digital storage device with already-stored images by determining if a percentage of a finite storage capacity of the digital storage device needed to store the captured and already stored images in the storage device exceeds a pre-set threshold value, wherein storage used of the finite storage capacity to store images may exceed the pre-set threshold value. If the percentage of storage space needed to store the captured and already stored images in the storage device exceeds the pre-set threshold value, then at least one of the captured and already stored images are compressed and all of the captured and already stored images, including all of the compressed images of the captured image and the already stored image, are stored in the storage device.
