    • The solid state image sensor of this invention includes multiple units, each of which includes first and second photosensitive cells 2a, 2b and a dispersive element 1a facing the first cell 2a. The element 1a passes a part of incoming light with a first color component to the second cell 2b. The first cell 2a receives a smaller quantity of light with the first color component than that of the light with the first color component incident on the dispersive element. The second cell 2b receives a greater quantity of light with the first color component than that of the light with the first color component incident on the dispersive element. The quantity of that part of the incoming light with the first color component is calculated based on the difference between photoelectrically converted signals supplied from the first and second cells 2a and 2b and information representing the ratio of the quantity of the light with the first color component received by the second cell to that of the part of the incoming light with the first color component.
    • 本发明的固态图像传感器包括多个单元,每个单元包括第一和第二感光单元2a,2b和面向第一单元2a的分散元件1a。 元件1a将具有第一颜色分量的入射光的一部分传递到第二单元2b。 第一单元2a接收具有第一颜色分量的较少量的光,其具有入射在分散元件上的第一颜色分量的光。 第二单元2b接收具有第一颜色分量的光量比具有入射到分散元件上的第一颜色分量的光的更大量的光。 基于从第一和第二单元2a和2b提供的光电转换信号之间的差值和表示光量与第一颜色分量的比率的信息计算具有第一颜色分量的入射光的该部分的量 由第二单元接收到具有第一颜色分量的入射光的一部分。

    • An image capture device according to the present invention includes an imaging lens 3, a light-transmitting section 2 with two polarizers, and a solid-state image sensor 1 that has multiple pixels and their associated polarization filters. A first polarization filter 50a is arranged to face a first group of pixels W1 and a second polarization filter 50b is arranged to face a second group of pixels W2. The respective transmission axes of the polarizing areas P(1) and P(2) of the light-transmitting section 2 form an angle θ between themselves. Also, the transmission axis of the first polarization filter 50a defines an angle α with respect to that of the polarizing area P(1). And the transmission axis of the second polarization filter 50b defines an angle β with respect to that of the polarizing area P(2). With such an arrangement adopted, the image capture device of the present invention can obtain images with parallax efficiently.
