摘要： Disclosed is a method for correcting color in a portable image projector in consideration of an effect of a background color when the portable image projector projects images. The method corrects the effect of the background color to be projected, using color constancy technique, and thereby represents high-quality image which can be projected on a white screen. The method includes the steps of determining if a background color exists on a projection screen using a portable camera, converting the size of a mask image in order to connect a spatial position of an original image and an image photographed by a camera, correcting brightness of the mask image in order to correct non-homogeneity of the brightness of the projected image due to the distribution of different brightness values of the background color, and correcting the background color in order to correct color distortion of the image projected in different colors on the background color. The background color correction step includes the sub-steps of initializing chromaticity of the white screen in advance, and correcting chromaticity using a technique of color constancy of human eyesight.
摘要翻译：本发明公开了一种当便携式图像投影仪投影图像时考虑到背景颜色的影响来校正便携式图像投影仪中的颜色的方法。该方法使用颜色常数技术校正要投影的背景颜色的效果，从而表示可投影在白色屏幕上的高质量图像。该方法包括以下步骤：使用便携式相机确定投影屏幕上是否存在背景颜色，转换掩模图像的尺寸以连接原始图像的空间位置和由相机拍摄的图像，校正亮度掩模图像，以便校正由于背景颜色的不同亮度值的分布导致的投影图像的亮度的非均匀性，并且校正背景颜色以校正在不同颜色上投影的图像的颜色失真背景颜色。背景颜色校正步骤包括预先对白色画面的色度进行初始化的子步骤，以及使用人眼视觉的颜色恒定性技术来校正色度。

摘要： A face recognition apparatus and method using plural face images includes detecting a reference face image from an image input for registration in advance, calculating plural face feature information from a frontal face image if the detected reference face image includes the frontal face image, generating plural compared face images using the calculated plural face feature information, and determining whether the input face image matches the generated plural compared face images by comparing the input face image with the plural compared face images. Face images having diverse points of view are generated through single user registration, and thus the face recognition ratio can be heightened.
