Abstract: A precision motion platform carrying an imaging device under a large-field-coverage lens enables capture of high resolution imagery over the full field in an instantaneous telephoto mode and wide-angle coverage through temporal integration. The device permits automated tracking and scanning without movement of a camera body or lens. Coupled use of two or more devices enables automated range computation without the need for subsequent epipolar rectification. The imager motion enables sample integration for resolution enhancement. The control methods for imager positioning enable decreasing the blur caused by both the motion of the moving imager or the motion of an object's image that the imager is intended to capture.

Abstract: Two image signals from a non-interlace scanning type CCD at predetermined horizontal and vertical sampling frequencies are respectively inputted to automatic gain controllers, then to a color separator where the input signals are separated into luminance signal and color difference signals. The luminance signal is processed by a two-dimensional filter which traps frequency components having ½ of the horizontal and vertical sampling frequencies. Accordingly, a variation in amplification characteristics of the automatic gain controllers is compensated as a variation of luminance signals having Nyquist frequencies in the horizontal and vertical directions. Thereby, bad effect due to variations in amplification characteristics of the automatic gain controllers is reduced even through two output signals from the non-interlace scanning type CCD are processed by the respective automatic gain controllers.

Abstract: The field portion (40) of a workpiece (14) that an electro-optical system (28) can image is deflected by a field-of-view deflector (38) and an array of light sources (42, 44) illuminates the workpiece. As the field of view (40) moves about the workpiece surface, individual sources (42, 44) in the light-source array are so turned on and off that all sources that could be imaged into the field of view by specular reflection are turned off. In this way, proper dark-field illumination is maintained.

Abstract: A digital camera includes a button to renew a displayed image. If an operator depresses the renewing button for 2 seconds or longer, then a continuous reproducing mode is set. If a finger is released from the renewing button, the mode is switched from the continuous reproducing mode to a normal reproducing mode. A CPU, in the continuous reproducing mode, expands thumbnail image data and magnifies the expanded data to display the thumbnail images on an LCD. In the normal reproducing mode, on the other hand, original image data is expanded, and an expanded original image is displayed on the LCD. That is, the thumbnail images are reproduced in a continuous manner during depression of a reproducing button by the operator, while the thumbnail image is turned into an original image if the operator releases his finger from the reproducing button.

Abstract: In observing images picked up by a plurality of cameras connected to a network in a surveillance camera system or the like, the conventional arrangement necessitates a client device to switch an image display obtained from one camera over to an image display obtained from another by a manual operation, which has been troublesome. To solve this problem, a camera control system is arranged to automatically switch an image display obtained from one camera over to an image display from another at suitable intervals. The camera control system is further arranged to automatically control the image pickup directions of each camera and, in the event of occurrence of an error in any of the cameras, to carry on its automatic control operation by skipping the camera at which the error has occurred.

Abstract: A method for resolution enhancement of a still-image made by a digital imaging device. The method allows the use of high-aperture-ratio sensing arrays that produce resolution-enhancement, independent of the angle of view. Resolution-enhancement is achieved using a multiple-exposure technique of a sub-pixel overtap in conjunction with a whole-pixel shift. The method suppresses color-aliasing in a multiple-exposure native-resolution mode and enables the use of a single camera for single-exposure and multiple-exposure modes.
