    • An image pickup apparatus includes a zoom lens, and 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. 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). The image pickup apparatus includes 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 (stored in) the shading correction parameter storage section.
    • 图像拾取装置包括变焦透镜和具有摄像表面的图像拾取元件,该图像拾取表面接收由变焦透镜形成的图像,并转换为电信号。 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)。 图像拾取装置包括阴影校正参数存储部分,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,该修正参数用于校正前后方向上的不对称阴影, 变焦透镜的表面侧和后表面侧,以及阴影校正部,其根据阴影的(阴影)的阴影校正参数进行由摄像元件拾取的图像的校正操作, 校正参数存储部分。

    • A zoom lens includes a positive first lens unit G1, a negative second lens unit G2 and a rear group having a positive refracting power having at least one lens unit. The lens unit located closest to the object side in the rear grout is a third lens unit G3 having a positive refracting power. The zoom lens has an aperture stop S disposed closer to the image side than the second lens unit G2 and closer to the object side than the lens surface located closest to the image side in the third lens unit G3. The zoom lens satisfies a prescribed conditional expression.
    • 变焦透镜包括正的第一透镜单元G1,负的第二透镜单元G2和具有至少一个透镜单元的正折射率的后组。 位于后浆料中最靠近物体侧的透镜单元是具有正折射力的第三透镜单元G3。 变焦透镜具有比第二透镜单元G2更靠近图像侧并且比靠近第三透镜单元G3中最靠近像侧的透镜表面更靠近物体侧的孔径光阑S. 变焦透镜满足规定的条件表达式。
