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.

摘要： A received light quantity detection device where high-sensitivity pixels and low-sensitivity pixels are formed is used for photometry. It is possible to perform measurement over the low range (for example, 0[EV] through 8[EV]with a single occasion of photometry. In the case that both the high-sensitivity pixels and the low-sensitivity pixels are saturated, it is possible to perform further measurement over the high range (for example, 8[EV] through 16[EV]) by narrowing the aperture or increasing the electronic shutter speed for retried photometry with a retried photometry. This reduces the time required to calculate a correct exposure value on image pickup apparatus such as a camera.
摘要翻译：将形成高灵敏度像素和低灵敏度像素的接收光量检测装置用于测光。可以通过一次光度测量在低范围（例如，0 [EV]至8 [EV]）上进行测量。在高灵敏度像素和低灵敏度像素都饱和的情况下，可以通过缩小光圈或者通过重试光度法增加用于重试测光的电子快门速度，在高范围（例如，8 [EV]至16 [EV]）上进行进一步的测量，这减少了计算在诸如照相机的图像拾取装置上的正确曝光值。

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.
