Abstract:
There is provided an image capturing apparatus including a light splitting section that splits light from an object into first light and second light in such a manner that (i) a split ratio of light in a specified wavelength range is different from a split ratio of light in a non-specified wavelength range and (ii) the second light has a smaller amount of light than the first light in the specified wavelength range, a high-sensitivity imaging element that receives the first light, and a low-sensitivity imaging element that receives the second light, where the low-sensitivity imaging element has a lower sensitivity than the high-sensitivity imaging element.
Abstract:
An image reader includes a photoelectric converter which reads light carrying image information, a plurality of amplifiers which amplify the photoelectrically converted image information by different amplification factors, a plurality of A/D converters which respectively convert the plurality of pieces of image information amplified by the amplifiers into digital signals, and a selector which selectively outputs the outputs of the respective A/D converters according to displacement of the image information.
Abstract:
A photographic printer having a video image printing system for making prints of video images displayed on a CRT, and a photographic image printing system using the CRT as an illumination light source for a film from which a photographic image is printed, including a control circuit for defocusing an electron beam by which a fluorescent screen of the CRT is stimulated to emit illumination light without rasters when the CRT is used in the film image printing system. The control circuit can either change an angle of deflection of the electron beam or stop deflection of the electron beam.
Abstract:
An automatic calibration circuit for a monitoring device in which a static image, such as may be derived from an X-ray camera or an ultrasonic imaging device, is displayed as a static image on CRT and the image projected and recorded on film. A uniform pattern is displayed on the CRT by setting a contrast control signal to a minimum value and a brightness control signal to a reference level. Then, the light outputted from the face of the CRT is measured at any arbitrary point on the face of the CRT. The value so measured is used to correct the brightness signal and contrast signal so as to maintain initially set brightness and contrast values for images displayed on the CRT.
