  • Patent number: 10992874
    Abstract: The present application related to a camera system and a camera fill light method. The camera system establishes a wireless communications connection with a fill light, captures an original image by a camera in the camera system, and then transmits a first test light signal to the fill light such that a first flash is performed by the fill light. The camera captures a first light source image during the first flash period of the fill light. A fill light controller in the camera system compares differences of the brightness or the chroma of different image information and, after determining the present location of the fill light, calculates a dislocation result of the present location of the fill light and the best placement location of the fill light. The camera system yields the dislocation result to the photographer via a notification message.

  • 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.

  • Patent number: 7664387
    Abstract: A communications apparatus is shown having an imaging device for capturing an image, and a flash for lighting an image to be captured. Also shown is the use of the apparatus. Software for matching a flash performance to other functions of a device is also shown. A radio communications apparatus embodiment is shown that comprises an imaging device including an image sensor and a rolling shutter, and a flash unit. The flash unit is operated at a certain flash frequency, and an exposure time is determined according to the flash frequency so that the image sensor is uniformly exposed by the rolling shutter during the determined exposure time.

    Abstract: An illumination controller for controlling an illumination device that irradiates an object to be photographed with illumination light. The illumination controller includes an introducing unit that introduces ambient light emitted to the object from a light source other than the illumination device; a processing unit that processes the ambient light introduced by the introducing unit to have a same characteristic as that of the illumination light; and an irradiation controlling unit that controls the ambient light processed by the processing unit so as to irradiate the object therewith as illumination, from a same path as the irradiation path of the illumination light.

    Abstract: Methods of using software to synchronize the control of a camera on portable media device with the photoflash on an external lighting apparatus. The Camera-Equipped Portable Media Device (CEPMD) utilizes an External Lighting Apparatus (ELA) as a light source to improve the lighting conditions for portable media device photography. Both ELA and CEPMD are controlled by software, which synchronize the photoflash image capture as well as post process the image to further enhance the image quality. Furthermore, in a preferred ELA embodiment, it acts as a protective case for the CEPMD.

  • Publication number: 20090097835
    Abstract: A camera includes a mode setting unit which sets an operation mode of the camera to a normal mode or an illumination apparatus control mode. A display unit selectively displays an image and information. A setting unit sets and changes operating conditions of an illumination apparatus. A communication unit instructs the operating conditions to the illumination apparatus. A control unit controls the mode setting unit to set the operation mode to the illumination apparatus control mode, and changes a display form of the display unit, when predetermined conditions are satisfied. The predetermined conditions include any one of the followings (1) the communication unit is attached to the camera, (2) the communication unit set to an illumination apparatus control mode is attached to the camera, and (3) the communication unit which is incorporated in the camera is set to an illumination apparatus control mode.

  • Patent number: 6418278
    Abstract: The camera of this invention includes an improved shutter system that has the same shutter waveform when a flash is employed and when a flash is not employed. In a preferred embodiment, the shutter system includes a shutter that is rotatably mounted to the camera and a shutter opening over which the shutter blade is disposed. A slidable plate in which a first aperture and a second aperture are disposed is coupled to the camera, so that the first aperture is disposed between the first shutter opening and the lens of the camera prior to taking a picture with the camera. The first aperture is preferably smaller than the second aperture. When a picture is taken, the shutter blade moves to uncover the shutter opening, and when the shutter opening is uncovered the shutter blade causes the slidable plate to slide with respect to the shutter opening so that the second larger aperture is disposed between the shutter opening and the camera lens.

  • Patent number: 6407512
    Abstract: Flash light is repeatedly emitted in a pulse state by intermittently turning on and off an IGBT. The flash light reflected by a subject is received by a phototransistor to integrate a received light amount with a capacitor. While the IGBT is turned off, a charging voltage of the capacitor is converted to digital data. Based on the obtained data, it is judged whether emitting the flash light is stopped or not.
