Abstract:
A photoelectric transformation device is provided to obtain an image with excellent repeatability of color by reducing the noise caused by a component except a region of visible rays as compared with a conventional technique. A plurality of pixels include a photoelectric transformation device(20) having a sensitivity of photoelectric transformation with respect to a wavelength region from a visible ray region to an infrared ray region. A visible ray region and an infrared ray region are defined as a transmission region in a color filter(22R,22G,22B) disposed in a light receiving surface in a part of the plurality of pixels. An infrared ray region is defined as a transmission region in an infrared filter disposed in a light receiving surface in the rest of the plurality of pixels. A cut filter(24) blocks light having a wavelength region of 650~750 nanometers, disposed in the light receiving surface of the plurality of pixels. A signal outputted from a pixel in which the color filter is disposed in the light receiving surface is corrected by a signal outputted from a pixel in which the infrared filter is disposed in the light receiving surface.

PURPOSE: A color and intensity measuring module is provided to precisely test an operation of a light emitting apparatus by providing luminous intensity and parametric value for the color. CONSTITUTION: An optical test module(10) includes a detector(12) to which light is radiated from an emitter. The detector(12) uses a plastic fiber connector(16) connected to an optical fiber cable(14). The detector(12) is positioned below a light shield so as to prevent ambient light from penetrating into the detector(12). An electronic unit(20) regulates a signal of the detector so as to process red, blue and green components of light. An additional electronic member(22) is provided to select one of detectors. A connector(24) is connected to the optical test module(10) so as to provide output values.
Abstract:
The invention relates to a method for producing a color sensor with a sensor characteristic which is adjusted by three sensor elements which each comprise an element characteristic, and a color filter cooperating with the sensor elements and consisting of color filter elements which each comprise a filter element characteristic, and to a color sensor. The problem of the invention of indicating a method with which a color sensor with a precisely adjustable sensor characteristic can be produced from several photosensitive elements and from simple filter elements is solved in that the particular filter element characteristics are adjusted in such a manner that they have in cooperation with the respective element characteristic an interim characteristic of the sensor which deviates from the sensor characteristic on the whole, wherein the sensor characteristic is generated from the interim characteristic by a transformation algorithm using transformation parameters.
Abstract:
Optoelectronic modules for proximity determination and ambient light sensing include hybrid optical assemblies configured with multiple field-of-views. The field of view in a region of the hybrid optical assembly can be dedicated to a first detector, while the field of views in another region of the hybrid optical assembly can be dedicated to both the emission of light and ambient light sensing. Embodiments relate particularly to implementation in a mobile phone or other portable electronic devices.
Abstract:
An electronic device may be provided with a display mounted in a housing. A color sensing ambient light sensor may measure the color of ambient light. The color sensing ambient light sensor may be mounted in alignment with an ambient light sensor window formed in an inactive area of the display. The color sensing ambient light sensor may be formed from detectors on a semiconductor substrate. The detectors may include detectors that have spectral sensitivity profiles matching those of color matching functions. The color sensing ambient light sensor may include an infrared light detector. Light redirecting structures such as a diffuser, prism film, negative lens film, or privacy film may be used in directing light into the ambient light sensor. The color sensing ambient light sensor may be calibrated by exposing the sensor to light sources of different types.
