Abstract: A camera system 100 has an imaging optical system L, an imaging component 45, a liquid crystal monitor 16, a body microprocessor 12, an aperture setting component 29, and an image display controller 15. The body microprocessor 12 allows a target aperture value and a reference aperture value to be set as set conditions and determines the reference aperture value on the basis of the target aperture value. The aperture setting component 29 adjusts a photography condition on the basis of the set conditions. The image display controller 15 displays part of a reference image a1 acquired by the imaging component 45 at the reference aperture value as a reference display image A1 in a first display region R131 and displays part of a target image b1 acquired by the imaging component 45 at the target aperture value a1 as a target display image B1 in a second display region R132.
Abstract: In a solid-state imaging device, bus lines are provided at both sides of an imaging area vertically to send vertical-transfer clock pulses to shunt wires disposed on or over the imaging area at both ends of the signal lines of the shunt wires. Bus lines disposed closer to a horizontal transfer register are placed at a boundary area of the imaging area and the horizontal transfer register. Since the bus lines pass through an upper layer of the boundary area, imaging performed by light receiving elements is not performed but dummy pixels having almost the same structure as the light receiving sections are disposed and vertical transfer registers are provided in the boundary area to just transfer signal charges by the vertical transfer registers with a characteristic similar to that in the imaging area to the horizontal transfer register.
Abstract: A desktop electronic magnifier in a first embodiment includes a monitor and a control panel mounted to the monitor so that access to the control panel cannot be blocked by any position of the monitor. In a second embodiment, a monitor is positioned atop a flat platform that surmounts the camera so that access to the control panel cannot be blocked by any position of the monitor. In a third embodiment, the control panel is mounted to the camera and the monitor is supported by a support surface independent of the magnifier. Access to the control panel is blocked only if the user positions the monitor in blocking relation to the control panel.

Abstract: A method for compensating pixel values of defective pixels in an image processing system is provided. First, a normal image is captured to obtain the pixel values of a plurality of pixels, and the pixel values of the defective pixels are then marked as a specific pixel value. When the pixel values are to be compensated, the locations of the defective pixels are determined by locating the specific pixel value, and the average values of the neighboring pixels of these defective pixels are calculated and used as the pixel values of these defective pixels, so as to complete a compensation procedure. Besides, the present invention further includes closing the shutter to capture a dark image with similar exposure condition as the normal image does. The compensation procedure is performed after subtracting the dark image from the normal image so that the noise caused by dark current can be eliminated.

Abstract: Apparatuses and methods for enhancing a “primary” large format, digital, macro-image with “secondary” image data are provided. The secondary image data is collected utilizing one or more secondary optical systems having at least one electro-optical detector array (e.g., a CCD array) and a specific set of optical mirrors or optical prisms, arranged in such a way that the secondary optical systems extend the angular angle-of-view of the primary optical system and the resultant digital image in at least two opposing directions, for instance, in the left and right and/or fore and aft directions. The primary image data and the secondary image data may be distinct and/or may include portions that overlap with one another. Further, the primary image data and the secondary image data may be collected at the same or different resolutions. The collected primary image data and secondary image data are utilized to generate a single output image.

Abstract: A pre-amplifier (column region unit) of a solid-state imaging device includes a pixel-signal controller. The pixel-signal controller, for each vertical signal line, detects the level of each pixel signal independently by a pixel-signal detector on the output side of a pixel-signal amplifier, and sets a gain independently to the pixel-signal amplifier according to the level of the signal. At a subsequent stage of the solid-state imaging device, an analog-to-digital (A/D) converter and a signal extending unit are provided. The A/D converter digitizes a pixel signal, and the digitized pixel signal is corrected by a gain set to the pixel-signal amplifier with reference to a classification signal from the pixel-signal detector, so that the dynamic range of signals of one screen is extended.
