A controlling value is calculated using a first white balance gain and a second white balance gain. Using the calculated controlling value, an image processing parameter is then modulated. Using this modulated image processing parameter, image data processing is performed, and storage, transmission, and the like of the image processing parameter are performed. This can realize advanced image processing reflective of the white balance gain.

A system and process provide an improvement to monitoring over-heating of components in an apparatus. Embodiments include a thermal sensor which may be coupled with a filter. A controller may store over-heat values for components in the apparatus. In response to a sensor signal detecting an over-heat threshold exceeded, the controller may trigger an alert. Detection of an over-heating event may trigger shutdown of the component or the entire device or system before damage occurs or escalates to other components. In some embodiments, the range of detection by sensors monitoring the same component may be extended by coupling each sensor with a different filter so that a wider range of heat signatures are available. Aspects of the method may select which sensor/filter combination has a best range of detection based on the number of pixels registering over or under a threshold value.

In a method and computer for visualizing a medical image data set, in particular a magnetic resonance image data set, the medical imaging data set is provided to the computer which determines a first subset of the medical image data set related to a first parameter and a second subset of the medical image data set related to a second parameter. A first color is assigned to the first subset and a second color is assigned to the second subset. The first subset is transferred to a display in a first color presentation using the first color and the second subset is transferred in a second color presentation using the second color. The first color presentation and the second color presentation are combined for visualizing the medical imaging data set.

Provided is a color camera that captures using environmental light, a monochrome camera that captures using infrared light, a signal processing unit that processes a signal of a color image output from the color camera and a signal of a monochrome image output from the monochrome camera, a storage unit that stores alignment information generated from a color image and a monochrome image captured in a state of sufficient environmental light, an alignment unit that performs an alignment based on alignment information to match positions of a subject shown in a color image and a monochrome image captured in a state of insufficient environmental light, and an image synthesis unit that acquires color information from the aligned color image and performs color conversion to colorize the monochrome image using the color information.

In a line sensor including color filters that are periodically disposed in a light-receiving-element row, a problem called a mixture of colors occurs. A mixture of colors occurs when light that has been transmitted through a color filter differing from a color filter corresponding to a light receiving element is incident upon the light receiving element. In a CMOS sensor 107 including a light-receiving-element row in which a plurality of photodiodes 1204 are disposed side by side in a main scanning direction and a plurality of color filters 1202 that are disposed in correspondence with the plurality of photodiodes 1204, the center of each color filter 1202 is displaced in a direction of the center of the light-receiving-element row from the center of the photodiode 1204 corresponding to the color filter.

An image forming apparatus forms an image on a sheet and conveys the sheet through a conveying path. The image forming apparatus includes a color detection sensor which detects a detection image formed on the sheet for generating an image forming condition and a white reference plate used to calibrate the color detection sensor. The white reference plate is arranged opposite to the color detection sensor with the conveying path interposed therebetween at a position where the white reference plate is not concealed by the sheet when viewed from the color detection sensor when the sheet is conveyed to the conveying path. The detection image is formed on a white reference plate side of the sheet. The color detection sensor reads the white reference plate and is calibrated according to a read result.
