摘要：
An image pickup apparatus includes an image pickup device that has high-sensitivity pixel devices receiving a relatively large amount of light and low-sensitivity pixel devices receiving a relatively small amount of light, an exposure control unit independently controlling exposure periods of the high-sensitivity pixel devices and the low-sensitivity pixel devices, and an image generation unit performing image generation on the basis of an output signal of the image pickup device. The image generation unit compares a high-sensitivity pixel evaluation image generated using data output from the high-sensitivity pixel devices with a low-sensitivity pixel evaluation image generated using data output from the low-sensitivity pixel devices by obtaining a difference or ratio between pixel values of corresponding pixels in the two evaluation images, and performs different types of image processing for a region composed of pixels each having a small difference and a region composed of pixels each having a large difference.
