  • Patent number: 10274370
    Abstract: A spectroscopic scatterometer detects both zero order and higher order radiation diffracted from an illuminated spot on a target grating. The apparatus forms and detects a spectrum of zero order (reflected) radiation, and separately forms and detects a spectrum of the higher order diffracted radiation. Each spectrum is formed using a symmetrical phase grating, so as to form and detect a symmetrical pair of spectra. The pair of spectra can be averaged to obtain a single spectrum with reduced focus sensitivity. Comparing the two spectra can yield information for improving height measurements in a subsequent lithographic step. The target grating is oriented obliquely so that the zero order and higher order radiation emanate from the spot in different planes. Two scatterometers can operate simultaneously, illuminating the target from different oblique directions. A radial transmission filter reduces sidelobes in the spot and reduces product crosstalk.

    Abstract: An image of a user's eyes and face may be analyzed using computer-vision algorithms. A computing device may use the image to determine the location of the user's eyes and estimate the direction in which the user is looking. The eye tracking technology may be used in a wide range of lighting conditions and with many different and varying light levels. When a user is near a light source, an automatic exposure feature in the camera may result in the user's face and eyes appearing too dark in the image, possibly reducing the likelihood of face and eye detection. Adjusting attributes such as the camera exposure time and the intensity and illumination interval of the light sources based on motion and light levels may improve detection of a user's features.

    Abstract: A light intensity control device includes a fixed opening 261, an aperture stop part 26 for controlling a light flux of incident light, a light intensity aperture part 24 for changing the size of an opening by moving a plurality of aperture blades to limit a light intensity of transmitted light and a ND filter 25 having a transparent area 253 and a light blocking area 254, which is arranged to be movable between a first light blocking state where the transparent area 253 faces the fixed opening 261 of the aperture stop part 26 and a second light blocking state where the light blocking area 254 faces the fixed opening. The moving of the ND filter 25 is carried out when the opening area of the light intensity aperture part 24 is a maximum.

  • Patent number: 8917349
    Abstract: A method and a system for forming an image of a scene are provided. The method includes capturing an image of the scene by exposing an image sensor to radiation from one part of the EM spectrum using one aperture and to radiation from another part of the EM spectrum using another aperture having a different size than the first aperture. Simultaneously with capturing the image, the scene is illuminated with radiation from the second part of the EM spectrum. The image is then formed on the basis of image data generated by the radiation from the first part of the EM spectrum and image data generated by radiation from the second part of the EM spectrum.

  • Patent number: 8908061
    Abstract: Receiving an instruction from a user to start sensing a still image, an image sensing apparatus performs scene determination based on an evaluation value of scene determination from an image sensed immediately after the luminance of the image converges to a predetermined range of a target luminance. The image sensing apparatus can accurately determine a scene of the image even the image sensor with a narrow dynamic range.

  • Patent number: 8908088
    Abstract: An image pick-up apparatus that is capable of correcting shading due to a closing travel operation of a shutter by a simple process. An image pick-up device picks up the image formed. A shutter unit opens and closes a substantially rectangular aperture corresponding to image pick-up area of the image pick-up device by means of a plurality of rotating shutter blades. The shutter blades travel in mutually opposite directions perpendicular to a long side of the aperture while keeping edges of the shutter blades facing the aperture are parallel to the long side so that edge portions that cover a center area of the aperture start shading the aperture before edge portions that cover four corner areas of the aperture start shading the aperture.

  • Patent number: 8896751
    Abstract: A digital photographing apparatus and a method of controlling the same. A continuous shooting speed of the digital photographing apparatus may be improved by simultaneously performing a shutter operation and a read out operation of image data. A disclosed method of controlling a digital photographing apparatus includes displaying an image signal input through an image pickup device as a live view image, performing a first operation by driving a shutter, reading data from the image pickup device, and performing a second operation by driving the shutter during a time period overlapping the reading of the data.

  • Patent number: 8891000
    Abstract: A system and method of driving shutter by an object moving tendency. In this method, an image capture process is performed, wherein a sensor captures a first image of a moving object in a first resolution in the image capture process. Then, a prediction moving module analyzes the first image to acquire a prediction time for the moving object to reach a feature position. Finally, an automatic shutter control process is performed according to the prediction time, and a second image with a second resolution is captured, wherein the value of the second resolution is larger than that of the first resolution. This method automatically captures the second image of the moving object when situated at the feature position by using the prediction moving system to analyze the moving object.

  • Patent number: 8818184
    Abstract: When a exposure controlling unit changes an aperture value of a diaphragm in a predetermined range, the exposure controlling unit also changes a transmittance of a variable ND filter so as to perform an exposure control and, after obtaining a proper exposure by changing both the aperture value and the transmittance, sets the aperture value after exposure control to Fa, and in a case where the aperture value at which a maximum resolving power is obtained is set to Fb, when a condition, Fa?Fb, is satisfied and the transmittance is neither the minimum nor the maximum, the exposure controlling unit brings the aperture value close to Fb and changes the transmittance so as to maintain the proper exposure after the exposure control.
