    • An image sensing apparatus is constructed in such a manner that a calculation priority setter 5111 (5111a) sets a priority between exposure amount control by an exposure amount control parameter calculator 511 (511a) serving as exposure amount controller, and dynamic range control by a dynamic range control parameter calculator 512 (512a) serving as dynamic range controller. Exposure control is executed by performing the exposure amount control and the dynamic range control based on a photoelectric conversion characteristic, by using exposure evaluation values detected by an evaluation value detector 405, based on the priority set by the calculation priority setter 5111 (5111a). This arrangement provides an image sensing apparatus capable of performing exposure control with high latitude, wherein a user is allowed to capture a subject in an optimal exposure state, with an appropriate dynamic range being secured, and control primarily based on the exposure amount control or control primarily based on the dynamic range control is performed on the priority basis.
    • 图像感测装置被构造成使得计算优先级设定器5111(5111a)设置由用作曝光量控制器的曝光量控制参数计算器511(511a)的曝光量控制与动态范围控制之间的优先级 作为动态范围控制器的范围控制参数计算器512(512a)。 基于由计算优先级设定器5111(5111a)设定的优先级,通过使用由评价值检测器405检测出的曝光评价值,通过进行基于光电转换特性的曝光量控制和动态范围控制来执行曝光控制。 这种布置提供了能够执行高纬度的曝光控制的图像感测装置,其中允许用户在适当的动态范围得到保证的情况下以最佳曝光状态拍摄被摄体,并且主要基于曝光量控制或控制 主要基于动态范围控制优先执行。
