    Abstract:  偶数画素行と奇数画素行とに分かれて配置されなる画素アレイ部(12)を有するCMOSイメージセンサ(10)において、短い蓄積時間のodd画素の読み出しを、長い蓄積時間のeven画素の露光開始部分で行う。これにより、even画素が飽和して当該even画素から信号電荷があふれ、その一部がeven画素と隣接するodd画素に入り込んだとしても、既にodd画素の読み出し動作が終わっているために、even画素が飽和した際のブルーミングによるodd画素の信号への影響を排除できる。隣接画素間で蓄積時間を異ならせる広ダイナミックレンジ化の手法を採るに当たって、ブルーミングによる低感度の信号への影響を排除する。

    Abstract: An image sensing device has an image cell (ICn) with a photo-sensitive element (FD), a detection node (C) and an output pin. Charges accumulated during a first period of time are transferred from the photo-sensitive element (FD) to the detection node (C), thereby obtaining a first voltage, and kept on the detection node (C) which is thus used as a memory. Some moments later, a first value corresponding to the first voltage is generated on the output pin, charges accumulated during a second period of time are transferred from the photo-sensitive element (FD) to the detection node (C), thereby obtaining a second voltage, and a second value is generated on the output pin corresponding to the second voltage. The signal thus generated is also proposed.

    Abstract: A method and device for capturing a mixed structured-light image and regular image using an integrated image sensor are disclosed, where the structured-light image is captured using a shorter frame period than the regular image. In order to achieve a shorter frame period for the structured-light image, the structured-light image may correspond to an image captured with reduced dynamic range, reduced spatial resolution, or a combination of them. The capturing process comprises applying reset signals to a pixel array to reset rows of pixels of the pixel array, reading-out analog signals from the rows of pixels of the pixel array and converting the analog signals from the rows of pixels of the pixel array into digital outputs for the image using one or more analog-to-digital converters.

    Abstract: An imaging device whose dynamic range can be wide with a simple structure is provided. In a circuit configuration and an operation method of the imaging device, whether a charge detection portion provided in a pixel is saturated with electrons is determined and an operation mode is changed depending on the determination result. First imaging data is captured first, and is read out in the case where the charge detection portion is not saturated with electrons. In the case where the charge detection portion is saturated with electrons, the saturation of the charge detection portion is eliminated and second imaging data is captured and read out.
