Abstract: An endoscope system includes: a first processor configured to perform first image processing on a set of image data; a second processor configured to perform second image processing on another set of image data; a third processor configured to generate, based on sets of image data output from the first and second processors, display image data; a recorder configured to record therein image data based on the sets of image data output from the first and second processors; a fourth processor configured to generate a first synchronization signal for synchronization among the first processor, the second processor, and the third processor; a fifth processor configured to generate a second synchronization signal for synchronization between the third processor and the recorder; and a controller configured to select one of the first and second synchronization signals, and perform control for synchronization between the third processor and the recorder.

Abstract: An endoscope system includes an imaging unit having an image sensor to image a subject, a light source emitting illumination light for illuminating the subject, and a laser treatment instrument which can emit laser light for treating the subject during emission of the illumination light. A control device for the endoscope system includes a determination unit which determines a state of use of the laser treatment instrument, and a brightness adjustment circuit which adjusts at least one of exposure time in imaging by the imaging unit and the amount of emitted light of the light source based on the result of determination by the determination unit.

Abstract: An image processing apparatus determines, with a freeze signal, an image of a freeze target, or determines, with no freeze signal, a latest image as an image to be displayed; performs color-balance adjustments using first and second parameters, based on the imaging signal of the determined image, thereby generating first and second imaging signals, respectively; generates a display purpose imaging signal, based on the generated first imaging signal; detects signals of plural color components included in the second imaging signal; calculates, based on the detected signals, a color-balance parameter for the color-balance adjustment; sets, when inputting no freeze signal, a latest color-balance parameter calculated, as the first and the second parameters, or sets, when the freeze instruction signal is input, a color-balance parameter corresponding to the image of the freeze target as the first parameter and the latest color-balance parameter as the second parameter.

Abstract: A control device for an imaging system includes a video signal acquisition unit, a photometric unit, and a luminance control unit. The video signal acquisition unit is configured to acquire a video signal obtained by taking an image of fluorescence radiated from a subject under excitation by an excitation light that is emitted onto the subject. The photometric unit is configured to acquire brightness of the fluorescence based only on a color-specific video signal of one color corresponding to the fluorescence, the color-specific video signal being included in the video signal. The luminance control unit is configured to adjust luminance of a fluorescent image formed from the video signal, based on the brightness of the fluorescence acquired by the photometric unit.
