The image processing method and device photograph a subject or transparent image to acquire calorimetric values of a subject image, acquire chromaticity information and illuminance information of a light source illuminating the subject and the transparent image, perform on the calorimetric values of the subject image chromatic adaptation correction based on the chromaticity information and the acquired illuminance information and contrast correction based on the illuminance, and correct the corrected calorimetric values to be output by an amount of flare in outputting the subject image, thereby enabling faithful reproduction of appearance. The method and device further perform at least one of contrast conversion and chroma conversion on the calorimetric values of the subject image based on a chromaticity value in a case where a degree of adaptation or an adaptation luminance is set higher than that determined for an illuminating color of the light source before performing the chromatic adaptation correction, thereby enabling faithful reproduction of appearance and preferred color reproduction of appearance.

The invention relates to an image coding apparatus which can improve the picture quality of an image. A quantization scale arithmetic operation section 43 calculates a coefficient of a quantization index based on a variance of values of a motion vector residual outputted from a motion vector residual variable buffer section 72 and an activity outputted from an activity buffer section 73. The quantization scale arithmetic operation section 43 calculates a quantization scale based on the coefficient of the quantization index calculated thereby and the quantization index outputted from the quantization index arithmetic operation section 42. The present invention can be applied to an image coding apparatus of the MPEG system.

To record a video signal on a recording medium so that a reproducing apparatus can faithfully reproduce an original color of the recorded video signal.A user can specify either a sRGB color space or an extended sRGB color space as the color space of the video signal to be recorded. A signal processing unit 131 generates a video signal (luminance signal Y and color-difference signal Cb/Cr) corresponding to the specified color space. An encoding/decoding unit 132 performs data compression on the video signal in accordance with the MPEG4-AVC standard to generate a compressed video signal to be recorded on a recording medium 135. A CPU 121 is configured to generate a color space identifier including information indicating the color space specified by the user and is configured so that an access unit including an SPS NAL unit in the compressed video signal includes an SEI NAL unit in which the color space identifier is stored. The video signal recorded on the recording medium 135 is a signal to which a color space identifier having information for a color space of that video signal is added.

The present invention relates to a recording apparatus and method, a storage medium and a program which allow data for a predetermined playback time to be recorded in a contiguous area on the data storage medium, even when an area in which data cannot be recorded exists on the data storage medium. While a stream unit for a predetermined playback time is being recorded on a storage medium 102, when a recording error occurs, a controller 138 searches for a contiguous blank area greater than the recording capacity of a contiguous recording area in which the stream unit is being recorded. Under the control of the controller 138, a drive 136 secures, in the beginning of the found area, an area having the same capacity as the data amounts of an IL auxiliary area and a recorded stream unit, records an unrecorded stream unit, and then copies the recorded stream unit. The present invention is applicable to video cameras.

An ink cartridge includes a movable member which includes a signal blocking portion disposed within an inner space of a translucent portion, and a float portion disposed within an ink chamber. The float portion is configured to move between a first position and a second position based at least on an amount of ink disposed within the ink chamber. Specifically, as the ink within the ink chamber is dispensed from the interior of the ink chamber to the exterior of the ink chamber a surface of the ink within the ink chamber moves in a first predetermined direction. Moreover, when the float portion moves from the first position to the second position each of the float portion and the signal blocking portion moves in a second predetermined direction which is slanted with respect to the first predetermined direction.
