    • An image pickup apparatus includes: a zoom lens; an image pickup element having an image pickup surface which receives an image which has been formed by the zoom lens, and converts to an electric signal; a shading correction parameter storage section which stores a shading correction parameter which differs at a front-surface side and a rear-surface side with respect to a center of an image, which is for correcting asymmetric shading at the front-surface side and the rear-surface side of the zoom lens; and a shading correction section which carries out correction operation of an image which has been picked up by the image pickup element, based on the shading correction parameter of the shading correction parameter storage section. When an object having a uniform brightness is captured, at any state from the wide angle end to the telephoto end, the zoom lens satisfies conditional expression (A).
    • 一种图像拾取装置,包括:变焦透镜; 图像拾取元件,其具有接收由变焦透镜形成的图像并转换为电信号的图像拾取表面; 阴影校正参数存储部,其存储相对于图像的中心在前表面侧和后表面侧不同的阴影校正参数,其用于校正前表面侧和后侧的非对称阴影 变焦镜头的表面侧; 以及阴影校正部,其基于遮蔽校正参数存储部的阴影校正参数,对由摄像元件拍摄的图像进行校正操作。 当捕获具有均匀亮度的物体时,在从广角端到望远端的任何状态下,变焦透镜满足条件表达式(A)。
