    • The present invention provides a solid state image sensing device capable of performing high-speed focal point adjustment without using a special optical system and a photographing apparatus including the device. Multiple photoelectric conversion elements are arranged and photoelectric conversion elements for auto focus (AF) are arranged between them. Concave and convex forms are formed, and the photoelectric conversion elements for rear side and front side AF are disposed in the concave and convex portions. The moving direction of a focusing lens is determined based on the difference between outputs of the photoelectric conversion elements for rear side and front side AF and the focusing lens is moved to the position where the contrast value obtained from the photoelectric conversion elements becomes the maximum.
    • 本发明提供一种能够在不使用特殊光学系统的情况下执行高速焦点调整的固态图像感测装置和包括该装置的拍摄装置。 布置了多个光电转换元件,并且在它们之间设置用于自动聚焦(AF)的光电转换元件。 形成凹凸形状,并且用于后侧AF和前侧AF的光电转换元件设置在凹凸部中。 基于用于后侧和前侧AF的光电转换元件的输出之间的差异来确定聚焦透镜的移动方向,并且聚焦透镜移动到从光电转换元件获得的对比度值变为最大的位置。
