摘要： Adaptive recoloring of displayed digital content automatically pursues specified active color palette goals while adhering to specified active color palette constraints. Source code editors, word processors, and other programs are enhanced by adaptive recoloring. Recoloring rules may specify coloring roles, colors, tolerances, color spaces, metrics, and other criteria. Recoloring may be triggered by a zoom or another change in user focus, by a brightness change, a screen size change, by notice of a user perception change, or by another event. Recoloring improves text legibility, assists user focus, compensates for differences in color perception and emotional impact, and increases color availability without degrading usability, for example. Transitions between words or other display items can be heightened. Branding colors may be preserved, in logos and text. Automatic selections may be overridden by a user command or by interactive tuning, with warnings given as appropriate.

摘要： An imaging system comprises two cameras and a processor. A first camera comprises a first grid of pixels configured to detect light in a broadband channel and a plurality of clusters of color filters sparsely arranged over the first grid of pixels. Each color filter passes light in a color channel to the grid of pixels. A second camera comprises a second grid of pixels configured to detect light in a broadband channel. The processor is configured to generate an aggregate image by combining a first image captured by the first camera and a second image captured by the second camera. The processor is also configured to add color values to the aggregate image based on color data captured by the first camera with the clusters of color filters. Additionally, the processor is configured to present the aggregate image with added color values on an electronic display.

摘要： An apparatus may include a projector that switches from emitting monochromatic light of a first color to emitting monochromatic light of a second color that is different from the first color. The apparatus may also include one or more variable-pitch diffraction gratings that diffract monochromatic light emitted from the projector. The apparatus may further include a controller that changes a pitch of at least one of the one or more variable-pitch diffraction gratings from a first pitch used when the projector is emitting monochromatic light of the first color to a second pitch used when the projector is emitting monochromatic light of the second color.

摘要： A video processing system includes a computing platform having a hardware processor and a memory storing a software code including a convolutional neural network (CNN). The hardware processor executes the software code to receive video data including a key video frame in color and a video sequence in gray scale, determine a first estimated colorization for each frame of the video sequence except the key video frame based on a colorization of a previous frame, and determine a second estimated colorization for each frame of the video sequence except the key video frame based on the key video frame in color. For each frame of the video sequence except the key video frame, the software code further blends the first estimated colorization with the second estimated colorization using a color fusion stage of the CNN to produce a colorized video sequence corresponding to the video sequence in gray scale.

摘要： Techniques are disclosed for capturing stereoscopic images using one or more high color density or “full color” image sensors and one or more low color density or “sparse color” image sensors. Low color density image sensors, may include substantially fewer color pixels than the sensor's total number of pixels, as well as fewer color pixels than the total number of color pixels on the full color image sensor. More particularly, the mostly-monochrome image captured by the low color density image sensor may be used to reduce noise and increase the spatial resolution of an imaging system's output image. In addition, the color pixels present in the low color density image sensor may be used to identify and fill in color pixel values, e.g., for regions occluded in the image captured using the full color image sensor. Optical Image Stabilization and/or split photodiodes may be employed on one or more sensors.

摘要： When a shutter release button of an image capturing apparatus is half pressed, an exposure time t is determined by a normal AE function. Then, if a shutter release button is fully pressed, an image is captured with the exposure time t, and the captured image is stored in a frame memory. At the same time, a color-coding circuit color-codes the captured image according to luminance thresholds, and the color-coded image is displayed on an LCD. If a user selects a color of an area equivalent to a main subject with reference to the color-coded image, a dynamic range, gamma characteristics, and the like of the image are determined so that the area in the selected color can have a correct luminance. The image is corrected accordingly, and image data acquired by the correction is stored in a recording part.
摘要翻译：当按下图像拍摄装置的快门释放按钮时，曝光时间t由正常的AE功能确定。然后，如果完全按下快门释放按钮，则以曝光时间t拍摄图像，并且将拍摄的图像存储在帧存储器中。同时，颜色编码电路根据亮度阈值对拍摄图像进行彩色编码，并且将彩色图像显示在LCD上。如果用户参照颜色编码图像选择与主要对象相当的区域的颜色，则确定图像的动态范围，伽马特征等，使得所选择的颜色中的区域可以具有正确的亮度。相应地校正图像，并且通过校正获取的图像数据被存储在记录部分中。

摘要： A synthetic color television system includes a color-filter for three primary colors and a brightness-sensitive medium. The color-filtering layers for the three primary colors are sequentially excited between the camera and objects taken by the camera so as to regulate the vertical and horizontal scanning signals and the sequence of signals of the three primary colors read from the brightness-changing signal series, or from a digital or analog source of image signals containing the above-mentioned signals transmitted to a displaying screen. A representation of the three primary color filtering screen displays synchronically the picture in the order of the three primary colors, creating a color picture effect through the persistence of vision on the three primary colors.
