  • Patent number: 12573195
    Abstract: A method for evaluating performance of an image signal processor according to various example embodiments includes: selecting at least two target colors from an original image generated by the image signal processor; defining a true color range in each of the target colors and identifying at least one false color pixel having a color deviating from the true color range in the original image; generating a reference image by changing a color of the false color pixel; and calculating a color error between the original image and the reference image.

  • Patent number: 11298428
    Abstract: An embodiment of the present invention provides a nanocarrier in a micelle structure, a pharmaceutical composition for diagnosis of cancer, comprising the same nanocarrier, and a method for preparing the same nanocarrier. The nanocarrier is obtained by dispersing a water-in-oil nanoemulsion containing an oil phase ingredient, a surfactant, and an aqueous phase ingredient inclusive of a cancer cell fluorescence-inducing substance and a cancer cell-targeting polysaccharide in water to remove the oil phase ingredient, whereby the nanocarrier includes the aqueous phase ingredient.
