    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 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： An electronic camera is provided with a touchscreen. When a cameraman touches the touchscreen on a principal subject in a captured image shown on the touchscreen, the touched portion is determined and the focus and exposure are adjusted in conformity with the principal subject. When the image is designated to be stored, positional information on the principal subject as well as image information is stored into a built-in memory or a detachable external memory. For this reason, wherever the principal subject is located on the image, the image-capturing is performed with favorable results. The positional information on the principal subject is utilized for printing or reproducing the image so as to perform image tone corrections such as correction of brightness and skin pigmentation in an area including the principal subject, so that a high-quality image can be printed or reproduced.
