Abstract: Example embodiments allow for training of encoders (e.g., artificial neural networks (ANNs)) to generate a color palette based on an input image. The color palette can then be used to generate, using the input image, a quantized, reduced color depth image that corresponds to the input image. Differences between a plurality of such input images and corresponding quantized images are used to train the encoder. Encoders trained in this manner are especially suited for generating color palettes used to convert images into different reduced color depth image file formats. Such an encoder also has benefits, with respect to memory use and computational time or cost, relative to the median-cut algorithm or other methods for producing reduced color depth color palettes for images.

Abstract: An information processing system (10) comprises: an acquiring means (110) for acquiring skin color information which is information relating to skin color of a target; an estimating means (120) for estimating luminance information of skin of the target on the basis of the skin color information; and a control means (130) for controlling at least one of camera parameter relating to exposure and illumination (19) when imaging the target on the basis of the luminance information.

Abstract: An image processing apparatus for controlling white balance of an image is provided. The apparatus detects a white region from image data and calculates a first white balance correction value based on data of the white region. The apparatus also detects, with use of machine learning, a region of a subject that has a preset specific color, from the image data, and calculates a second white balance correction value based on a color of the region of the subject. The apparatus calculates a white balance correction value to be applied to the image data, based on the first white balance correction value and the second white balance correction value.
