摘要: Es wird ein Verfahren zur Farbanpassung von farbigen Bilddaten angegeben, die von einem Bildsensor (18) als eine Vielzahl von Bildpunkten mit jeweils mehreren Farbkomponenten aufgenommen werden, wobei den Bildpunkten jeweils neue, farbangepasste Farbkomponenten zugewiesen werden und die Information, welche neuen Farbkomponenten zuzuweisen sind, durch ein Verfahren des maschinellen Lernens bestimmt wird, das vorab eine Zuordnungsvorschrift bestimmt, die möglichen aufgenommenen Farbkomponenten farbangepasste Farbkomponenten zuweist, wobei dann die Farbanpassung ohne weitere Beteiligung des Verfahrens des maschinellen Lernens mit der Zuordnungsvorschrift erfolgt.

摘要: An example of an information processing system includes a moving object including a camera and including a white area in an exterior of the moving object. An image capturing range of the camera includes the white area. It is determined whether or not each of pixels in a preset specified area that includes the white area in an image captured by the camera is white, and if the number of pixels that are white according to the white determination exceeds a predetermined number, white balance is performed to adjust the pixels that are white according to the white determination in the specified area closer to white.

摘要: An image processing apparatus includes adjustment means (501) configured to adjust a color of an input image based on a correction level defining a degree to which the color of the input image is to be corrected, calculation means (102) configured to calculate a first white balance control value based on the input image, evaluation means (104, 304, 502) configured to evaluate whether the first white balance control value is valid, and setting means configured to set a second white balance control value based on a result of the evaluation by the evaluation means, wherein the evaluation means (104, 304, 502) determines an evaluation criterion for evaluating whether the first white balance control value is valid based on the correction level determined by the adjustment means (501).
