摘要： A dynamic shutter mechanism for use with a still or motion video camera which is operable at variable shutter speeds to capture high speed events. The shutter mechanism includes a pair of apertured shutter discs which are independently driven by separate motors. Phase lock loop control circuits lock the speed and phase of each disc to the vertical and horizontal sync rates of the video camera. The video signal produced by the video camera produces a control signal which is indicative of the intensity of light of a captured scene. The control signal controls the speed of the shutter mechanism by changing the relative rotational position of the shutters and consequently the relative exposure aperture. In a preferred shutter mechanism the shutter discs are mounted coaxially and are driven by coaxial disc motors.

摘要： This invention is directed to reducing the size of the memory required to store correction information, by defining the two-dimensional non-uniformity characteristics in terms of two functions that are orthogonal. The orthogonal correction functions are stored in separate memories. During a scan, a pixel counter addresses the X memory while a line counter addresses the Y memory. The correction factors thus obtained are applied sequentially to correct the pixel data value at the current X and Y coordinates.

摘要： A still video camera produces a still signal for recording on a magnetic disk and a movie signal for displaying in an electronic viewfinder. In recording the still picture . . . after previewing the scene in the viewfinder . . . , a vertical synchronizing signal is recorded in predetermined relation to a reference position on the disk. Instead of phase locking the disk drive to the vertical synchronizing signal, the time base of the camera is "locked" to variations in the location (phase) of the reference position. The camera is thus affected by a relatively instantaneous reset of the time base rather than an inertially-limited adjustment of the drive motor, which tends to "blind" the electronic viewfinder for the duration and renders previewing unacceptable. By attempting the video reset only after the disk has been stabilized at a standard velocity (by a velocity servo) and by "windowing" the reference position for "acceptable" phase error, the viewfinder is further unburdened of visually-disruptive effects that impede effective still photography.

摘要： A digital imaging device captures an image and generates a color signal from the image for application to an output device having specific color sensitivities, the imaging device further being one of many devices of the same type useful with the output device. The digital imaging device, for example a digital camera, includes a color sensor for capturing the image and generating a color signal from the captured image, the color sensor having predetermined spectral sensitivities, and an optical section that is interposed in the image light directed to the color sensor, the optical section also having predetermined spectral characteristics. The combination of the spectral sensitivities of the color sensor and the spectral characteristics of the optical section uniquely distinguish this particular imaging device from other imaging devices of the same type. By providing a set of matrix coefficients uniquely determined for this imaging device, the matrix coefficients optimally correct the spectral sensitivities of the color sensor and the spectral characteristics of the optical section for the color sensitivities of the output device.

摘要： An electronic camera is adapted for processing images of different resolution to provide a user selectable image record size. A buffer memory is provided for storing color image pixels from a sensor as baseband signals corresponding to at least one image. A timing controller responsive to a resolution mode switch controls the order in which color image pixels are selected for storage in both vertical and horizontal directions. The order selected by the resolution switch includes a full resolution mode, and at least one reduced resolution mode in which the color image pixels are subsampled such that each chrominance image pixel is selected to be spatially adjacent to a selected luminance image pixel. Additionally, the buffer memory can store a burst of low resolution images.
