    • In a color image sensor having alternating rows of photosensitive pixels of first and second patterns of spectral sensitivity to one or more of first, second, and third colors, the method of reading out the sensor comprising the steps of:reading out a group of three sequential rows of pixels, by combining the two rows having pixels of the same pattern of spectral sensitivity into a single read-out row of pixels and dumping the row of pixels having the different pattern of spectral sensitivity; andrepeating the readout step until the sensor is completely read out so that sequential readout rows of pixels read out from the sensor have alternating rows of pixels of first and second patterns of spectral sensitivity to one or more of the first, second and third colors, the sensor thereby being read out at a faster frame rate while preserving the color pixel pattern of the sensor.
    • 在具有对第一和第二颜色中的一种或多种具有第一和第二光谱灵敏度图案的交替行的感光像素的彩色图像传感器中,读出传感器的方法包括以下步骤:读出一组三 通过将具有相同模式的光谱灵敏度的像素的两行组合成单个读出的像素行并且倾倒具有不同光谱灵敏度模式的像素行; 并且重复所述读出步骤,直到所述传感器被完全读出,使得从所述传感器读出的顺序读出行的像素具有第一和第二光谱灵敏度图案的像素行,其中所述第一和第二颜色中的一个或多个颜色, 从而以更快的帧速率读出传感器,同时保持传感器的彩色像素图案。
