  • Patent number: 8964111
    Abstract: The illumination apparatus includes a reflector unit to reflect a light flux from a light source. The reflector unit includes a first reflector and a second reflector whose relative positions are changeable to change an illumination angle. At a first illumination angle, the second reflector is disposed inside the first reflector, and the light flux from the light source is reflected by the second reflector to exit from the reflector unit. At a second illumination angle smaller than the first illumination angle, the first reflector is disposed further on a light exit side than the second reflector, and the light flux from the light source is reflected by at least one of the first and second reflectors to exit from the reflector unit. A distance between the light source and the second reflector at the second illumination angle is shorter than that at the first illumination angle.

  • Patent number: 8964083
    Abstract: The invention discloses a CMOS image sensor, a timing control method and an exposure method thereof. The image sensor includes a pixel array composed of multiple pixel rows and a control chip controlling the array. The control chip controls each pixel row to expose in the exposure time during one exposure period of the pixel row, and then wait predetermined time after the exposure time to output data. In the invention, the exposure time of the image sensor is separated from the time of outputting data. Therefore, the working mode of the image sensor can be controlled more flexibly. By the manner of controlling the pixel rows in the sub-array of the image sensor to expose synchronously, the flash time of the light source is the same as the exposure time of each single sub-array, thereby improving the utilization efficiency of the source energy and ensuring real-time image sampling.

    Abstract: This document describes various apparatuses and techniques for rapid synchronized lighting and shuttering. These apparatuses and techniques are capable of capturing two images, where one of the images integrates multiple exposures during which an image area is illuminated by a light source and another of the images integrates multiple exposures during which the image is not illuminated by the light source. The image area can be illuminated by rapidly flashing the image area with the light source and synchronizing a shutter to permit one image sensor to capture an image when the image area is illuminated and another image sensor to capture the image area when the image area is not illuminated. These two images can be captured concurrently or nearly concurrently, thereby reducing or eliminating motion artifacts. Further, these apparatuses and techniques may do so with slow and relatively low-cost cameras and relatively low computational costs.

    Abstract: Certain aspects of this disclosure relate to an image signal processing system that includes a flash controller that is configured to activate a flash device prior to the start of a target image frame by using a sensor timing signal. In one embodiment, the flash controller receives a delayed sensor timing signal and determines a flash activation start time by using the delayed sensor timing signal to identify a time corresponding to the end of the previous frame, increasing that time by a vertical blanking time, and then subtracting a first offset to compensate for delay between the sensor timing signal and the delayed sensor timing signal. Then, the flash controller subtracts a second offset to determine the flash activation time, thus ensuring that the flash is activated prior to receiving the first pixel of the target frame.

  • Patent number: 8817171
    Abstract: In an imaging apparatus having LED 1j for emitting light toward an object, an imaging unit 1 having CCD 1d generates a first object image with LED 1j emitting light and a second object image with LED 1j emitting no light. Average brightness of the first object image and average brightness of the second object image are calculated. Brightness difference between the average brightness of the first object image and the average brightness of the second object image is calculated. Brightness difference of the object is obtained using the calculated brightness difference between the first and second object images, and under control of CPU 9, a process is executed for adjusting exposure conditions based on the brightness difference of the object.

  • Patent number: 8810717
    Abstract: The camera body includes an imaging element, a hot shoe, an internal light source, and a camera controller. The camera controller is configured to calculate an evaluation value on the basis of the image data produced by the imaging element, and perform video autofocusing on the basis of the evaluation value. When the camera controller decides that the auxiliary light is needed, and that the flash device mounted to the hot shoe has an external auxiliary light source arranged to emit near infrared light, the internal light source emits light during the video autofocusing.

  • Patent number: 8804029
    Abstract: Example apparatus and methods concern controlling a variable flash to improve image detection. One example apparatus includes a digital camera and a variable flash configured to be controllable to operate at different selected illumination levels. The apparatus may be configured to identify a current imaging condition associated with the digital camera and to then determine a lux setting for the variable flash as a function of the current imaging condition. The flash may then be controlled as a function of the lux setting for subsequent image acquisition. The acquisition, analysis, and flash control may be exercised until a desired illumination is achieved. In one embodiment, determining the current imaging condition may include analyzing a frame acquired from the digital camera for attributes including image brightness, and edge detectability. In one embodiment, input from a light sensor may also be considered.

  • Patent number: 8797450
    Abstract: An approach is provided to adjust illumination color temperature at a flash unit of a camera. Data that corresponds to the ambient light of a physical environment is collected, such as at a color temperature meter included in the camera. The ambient light has a distribution of color temperatures that cycle over a fixed time period. When a flash request is received, a time is calculated at which the flash unit will flash. One of the color temperatures is identified from the distribution of color temperatures with the identified color temperature being the predicted color of the ambient light that will be present in the physical environment when the flash unit flashes. The color temperature of the flash unit is set to the identified color temperature.

  • Patent number: 8786767
    Abstract: This document describes various apparatuses and techniques for rapid synchronized lighting and shuttering. These apparatuses and techniques are capable of capturing two images, where one of the images integrates multiple exposures during which an image area is illuminated by a light source and another of the images integrates multiple exposures during which the image is not illuminated by the light source. The image area can be illuminated by rapidly flashing the image area with the light source and synchronizing a shutter to permit one image sensor to capture an image when the image area is illuminated and another image sensor to capture the image area when the image area is not illuminated. These two images can be captured concurrently or nearly concurrently, thereby reducing or eliminating motion artifacts. Further, these apparatuses and techniques may do so with slow and relatively low-cost cameras and relatively low computational costs.
