    Abstract: An imaging apparatus includes: a distance measurement unit that measures distance values of a plurality of points in a first area which has a focus point as a reference point; a statistical unit that calculates statistics indicating a variation in the measured distance values of the plurality of points in the first area; a size determination unit that determines the size of a second area which has the focus point as a reference point, on the basis of the calculated statistics; a contrast evaluation value calculation unit that calculates a contrast evaluation value on the basis of an image of the second area; and a focusing unit that moves a focus lens to a lens position determined on the basis of the calculated contrast evaluation value.

    Abstract: An image display method includes the steps of: acquiring a third image formed by applying dynamic range extension processing to a first image and a second image photographed with low sensitivity or low exposure with respect to the first image, or a fourth image without dynamic range extension processing; displaying the acquired image in a transmissive type display panel; and making backlight luminance of a segment corresponding to a high luminance portion in the third image higher than backlight luminance of a segment corresponding to a low luminance portion when the acquired image is determined to be the third image.

    Abstract translation: 一种图像显示方法包括以下步骤:获取通过对第一图像应用动态范围扩展处理形成的第三图像和相对于第一图像以低灵敏度或低曝光拍摄的第二图像,或没有动态范围扩展的第四图像 加工; 在透射型显示面板中显示所获取的图像; 并且当所获取的图像被确定为第三图像时,使与第三图像中的高亮度部分相对应的片段的背光亮度高于对应于低亮度部分的片段的背光亮度。
