  • Patent number: 10827129
    Abstract: The present disclosure minimizes the degradation of image quality when an active image and a passive image are combined. The present disclosure provides an image processing apparatus that includes a correlation amount calculation section and a combination section. The correlation amount calculation section calculates the amount of correlation between the luminance of an active image captured by irradiating light and the luminance of a passive image captured without irradiating light. The combination section combines the luminance of the active image with the luminance of the passive image in accordance with the calculated amount of correlation. The above configuration minimizes the degradation of image quality when the active image and the passive image are combined.

  • Patent number: 10798356
    Abstract: The present disclosure provides a white balance processing method. The white balance processing method includes the following. Each image of the plurality of successive frame images is processed to determine color temperature corresponding to a main light source. It is determined whether a variation of primary color temperature is greater than or equal to a predetermined threshold. The variation of primary color temperature refers to a difference between the color temperature of the main light source in a second frame image subjected to the color temperature variation and the color temperature of the main light source in a first frame image subjected to the color temperature variation. The white balance process is performed on the second frame image subjected to the color temperature variation according to the color temperature of the main light source in the first frame image subjected to the color temperature variation when the variation of primary color temperature is less than the predetermined threshold.
