  • Patent number: 10904449
    Abstract: Systems and methods described herein are directed to capturing intrinsic color images of subjects. A camera may be equipped with a light source that is coaxial to the camera's image sensor and configured to emit a pulse of light of short duration. During image capture of a subject, the camera light source may emit the pulse of light through the lens barrel of the camera and stop emission of light before the reflected light from the light source returns. Thereafter, the camera lens receives the reflected light from the light source (with the light source no longer emitting light) and charge is collected at one or more image sensor photodetector sites of the camera.

    Abstract: An optical lighting device includes a radiation detector, a first light source and a second light source. The radiation detector includes a semiconductor chip and an optical filter, and has a spectral sensitivity distribution. The first light source generates white radiation. The second light source generates monochrome radiation in the visible spectral range, wherein radiation emitted by the first light source and radiation emitted by the second light source are superimposed to yield mixed radiation which includes a wavelength spectrum. The wavelength spectrum of the mixed radiation is adapted to the spectral sensitivity distribution of the radiation detector.

  • Patent number: 8135271
    Abstract: A method of calibrating an autofocus (AF) lighting device of a camera is disclosed. A reference image is captured with light projected from the AF lighting device, and a relative position of a central coordinate of the projected light with respect to a central coordinate of the reference image is stored. When operating the camera, the AF lighting device is activated to emit light after a shutter button of the camera is pressed halfway down, and a preview picture is displayed on a panel of the camera. A central position of the emitted light is then transposed toward a center of the panel according to the stored relative position.

  • Publication number: 20110243541
    Abstract: A defocus calibration module is applied in a light-sensing system utilized for sensing a measured object for generating a sensed image. The light-sensing system comprises a light-emitting component, a focusing component, and an image sensor. The light-emitting component emits a detecting light to the measured object so that the measured object generates a reflecting light. The focusing component focuses the reflecting light to the image sensor. The image sensor generates the sensed image according to the reflecting light. The defocus calibration module has a calibrating object for blocking a part of the detecting light and the reflecting light for forming images at a first and a second calibration imaging locations in the sensed image. In this way, the defocus calibration module calculates a defocus parameter representing the defocus level of the light-sensing system according to the first and the second calibration imaging locations, and accordingly calibrates the sensed image.

  • Patent number: 8004600
    Abstract: A composite image device having image capturing, laser pointing, lighting and related functions in one includes a first perspective window, a second perspective window, a third perspective window, an image capturing module, laser source module, a light source module and a switchable light modulating module. The image capturing module captures ambient light through the first perspective window to generate digital image data. The laser source module emits a laser through the second perspective window. The light source module emits illuminating light through the third perspective window. The switchable light modulating module includes at least a light modulating gate and a switching device for moving the at least a light modulating gate to a position relatively parallel to the second or third perspective window to modulate the emitted laser or the emitted illuminating light.

    Abstract: A temperature compensated liquid lens is disclosed in which wait times for the liquid lens to respond to an applied control voltage or calculated in advance and stored in a table. A temperature sensor is utilized with the liquid lens that provides temperature data to the controlled circuitry. The wait time for the liquid lens to respond is then minimized to be no more than the minimum required time for the liquid lens to respond to the controlled voltage enough to focus the image to a prescribed level of quality.

  • Patent number: 7953318
    Abstract: Unless a release button is pressed halfway to input a command to prepare for capturing a still image, a focus lens is moved at predetermined intervals to focus roughly on a subject. When the release button is pressed halfway, the present position of the focus lens is detected. If the position of the focus lens is closer to a lens terminal on a short shooting distance side, the focus lens is moved from the lens terminal on the short shooting distance side toward a lens terminal on a long shooting distance side. If the position of the focus lens is closer to the lens terminal on the long shooting distance side, the focus lens is moved from the lens terminal on the long shooting distance side toward the opposite lens terminal. When an in-focus position is detected while the focus lens is being moved, the focus lens is immediately set at the in-focus position.

  • Publication number: 20110043682
    Abstract: A method for assist in focal length detection is adapted to a digital camera having a flash. The method includes the following steps. First, the flash of the digital camera is actuated and an image having a face portion is captured. Afterwards, an exposure feature value of the face portion in the image is calculated. A focus range comparison table is looked up according to the exposure feature value to obtain an initial focus position. Then, a focus procedure is performed according to the initial focus position to obtain a target focal length. After the target focal length is obtained, a flash feature value of the image is further calculated, and a guide number (GN) and a diaphragm value are set according to the flash feature value.
