Color calibration of color image rendering devices, such as large color displays, which operate by either projection or emission of images, utilize internal color measurement instrument or external color measurement modules locatable on a wall or speaker. A dual use camera is provided for a portable or laptop computer, or a cellular phone, handset, personal digital assistant or other handheld device with a digital camera, in which one of the camera or a display is movable with respect to the other to enable the camera in a first mode to capture images of the display for enabling calibration of the display, and in a second mode for capturing image other than of the display. The displays may represent rendering devices for enabling virtual proofing in a network, or may be part of stand-alone systems and apparatuses for color calibration. Improved calibration is also provided for sensing and correcting for non-uniformities of rendering devices, such as color displays, printer, presses, or other color image rendering device.

The disclosure relates to the field of displaying a projected picture, and particularly to a projection device, and a method for adjusting a projected picture. In an embodiment of the disclosure, the method includes: acquiring an image of a physical screen through a camera, and determining a projection of the physical screen onto a vision plane of the camera; determining rotation parameters and translation parameters of the projection device according to the vision plane and the projection of the physical screen; and adjusting the projection device according to the rotation parameters and the translation parameters of the projection device.

An automatic alignment apparatus applicable to assembly of an optical output module and associated methods are provided. The automatic alignment apparatus includes: an alignment tool, a beam splitter, cameras, and a processing circuit. The alignment tool is arranged to hold parts of the optical output module, and align the parts to each other according to at least one movement control signal, where the parts include a radiation source module and an optical component module. The cameras capture images to generate image signals carrying the images, and the beam splitter splits the optical path into associated sub-paths. The processing circuit generates at least one movement control signal according to at least one image signal within the image signals to perform movement control of at least one part of the parts. The alignment tool automatically aligns the parts to each other according to the at least one movement control signal.

A subject is imaged repeatedly and color images of the subject are obtained. A color histogram is generated from the color subject image obtained and a representative color is decided from the color histogram generated. A specific color range that can be considered a color identical with the representative color is decided from the color histogram and representative color. Color outside the specific color range in the color subject image is changed to gray, an image of the subject in which the non-specific colors have been changed to gray is obtained and the image is displayed. Processing such as deciding the specific color range is repeated. When an instruction to fix the specific color is issued, the specific color range is fixed.

A medical imaging system having a processor with software executing thereon is provided for processing and display of multiple bandwidths of video in multiple display areas. The system receives a video signal with a plurality of portions and generates at least two signals there from. Each of the two signals has a bandwidth for display in a different display area. The two signals are updated so that each component displays a different portion of the input video signal, and the two signals may be combined for display on a single display device having two display areas.

A device for reproducing guidance on a task including a plurality of steps is provided. The device includes an input device with which a user selects from which position of the guidance is to be reproduced; and a player configured to, where a designated step corresponding to the position selected by the user from among the steps is a particular step, jump a playback progress to the position selected to play the guidance, the particular step being an initial step of steps having not yet been performed completely, and, where the designated step is not the particular step, jump the playback progress to a position of the particular step to play the guidance.
