摘要:
A setting for white balance used by a camera during image-capturing can be reflected in a printer, thereby preventing, during printing, execution of such correction as negates an atmosphere of a light source in a recorded image in which the atmosphere has been intentionally allowed to remain. A camera used for a system of the present invention is a digital camera having a white balance process function of allowing the atmosphere of a photographing light source to remain in an image. During image-capturing, WB adaptation rate information indicative of a level of white balance correction is recorded on a recording medium as additional information. A printer reads the WB adaptation rate information for the camera via the recording medium to control white balance in accordance with the setting for the WB adaptation rate. For example, if the WB adaptation rate is less than 100%, then an AWB process executed by the printer is turned off to print the recorded image without changing its tints.

摘要:
An image combined high sensitivity image and low sensitivity image is provided with well-adjusted white balance and broad dynamic range. The image is obtained by multiplying the combined data by total gain that depends on scene. A white balance is adjusted with gain value calculated from of high output image data. Lv value representing luminance is calculated and compared with a threshold to decide whether or not the high sensitivity image and the low sensitivity image should be combined. First gamma correction unit performs gamma-correction for the image signal derived from the high sensitivity signal with first gamma character, second gamma correction unit performs gamma-correction for the image signal derived from the low sensitivity signal with second gamma character that is different from the first gamma character, and addition unit combines the image signal from the first gamma correction unit and the image signal from the second gamma correction unit.

摘要:
A digital camera has a feature to photograph a subject and record the image data onto a recording medium in a dynamic range wider than that required for printing, the digital camera further having a feature to store tag information into an image file, together with the image data, and record the image file onto the recording medium, the tag information including: range compression information indicating whether dynamic range compression has been made; maximum range information indicating the maximum subject reflection factor before and after the dynamic range compression; and knee point information indicating the subject reflection factor assumed when the dynamic range compression was made.
