发明名称 White balance correcting device for an image sensing
摘要 An image sensing apparatus comprises a color image sensor which produces a time-sequential image signal which sequentially includes a plurality of color components, and a color temperature sensor which is independent of the color image sensor and produces a time-sequential sensed signal which sequentially includes a plurality of color components corresponding to the plurality of color components of the time-sequential image signal produced by the image sensor. A processor selectively processes the time-sequential image signal produced by the color image sensor and the time-sequential sensed signal produced by the color temperature sensor. White balance control circuitry controls the white balance of color signals output from the color image sensor which have been obtained through the processing means on the basis of outputs of the color temperture sensor which have been obtained through the processing means.
