摘要:
An imaging apparatus includes an imaging device, an imaging device deriving unit and a signal processing unit. Pixels of the imaging device include a first pixel group and a second pixel group. The imaging device driving unit exposes the first pixel group during a first exposure period, exposes the second pixel group during a second exposure period, and reads first image data captured by the first pixel group and second image data captured by the second pixel group separately. The signal processing unit performs image processing for the first and second image data. A first shooting mode and a second shooting mode are provided. In the first shooting mode, the signal processing unit performs the image processing for the first and second image data separately to generate two pieces of subject image data. In the second shooting mode, the signal processing unit combines the first and second image data.

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.
