| 20090009616 | IMAGING APPARATUS AND SIGNAL PROCESSING METHOD - An imaging apparatus which enables correction of signal deterioration responsible for transfer deterioration occurred in a horizontal charge transfer path is provided. Provided that positions of “n” transfer packet formed in a horizontal charge transfer path in correspondence to “n” vertical charge transfer paths are expressed as a coordinate “i” (i=1, 2, 3, . . . n), a solid-state imaging device is exposed under exposure conditions, and reference charges generated in photoelectric conversion elements upon the exposure are accumulated in transfer packets located at odd coordinates. The charge accumulation packets accumulating the reference charges and other empty packets are transferred horizontally, whereby a reference signal responsive to the reference charge and an untransferred signal responsive to a charge in the empty packet are output. The thus-output signals are stored in memory. Deterioration of an imaging signal S(i) responsive to the charge accumulated in the transfer packet located at the coordinate “i” in a photographing mode during exposure is compensated for in accordance with the data stored in the memory and the imaging signal S(i). | 01-08-2009 |
| 20110058083 | SOLID STATE IMAGING DEVICE WITH HORIZONTAL TRANSFER PATHS AND A DRIVING METHOD THEREFOR - In a solid state imaging device, signal charges are branched to be output to in the form of one or plural outputs. At a horizontal transfer speed not lower than a predetermined transfer speed, the imaging device transfers signal charges of color attributes classified by a branching section, to plural horizontal transfer paths, where the signal charges are converted into analog voltage signals, which will be output synchronously. At a horizontal transfer speed lower than the predetermined transfer speed, the analog voltage signal converted is output from, e.g. the horizontal transfer path which has been selected. Output amplifiers arranged on the horizontal transfer paths are differentiated in sensitivities in detecting signal charges, depending on color attributes of signal charges supplied, and output the analog voltage signals. | 03-10-2011 |

| 20080239129 | METHOD AND DEVICE FOR DRIVING SOLID-STATE IMAGING DEVICE, IMAGING APPARATUS, AND IMAGE SYNTHESIZING METHOD - A method for driving a solid-state imaging device including a plurality of pixels arranged in a two-dimensional array, each of the plurality of pixels accumulating a signal charge according to an amount of incident light, is provided. The method includes: performing electron multiplication of a first signal charge at a first multiplication factor to output a first image signal; and performing electron multiplication of a second signal charge at a second multiplication factor to output a second image signal, at least the first and second image signals being image signals of the same scene of a subject and being successively output. | 10-02-2008 |
| 20080246863 | CCD SOLID-STATE IMAGING DEVICE, PHOTOGRAPHIC APPARATUS AND IMAGE DATA CORRECTION METHOD - A CCD solid-state imaging device is provided and includes: a semiconductor substrate; a plurality of photodiodes arranged in a two-dimensional array; a plurality of vertical charge transfer paths, each reading a signal charge from the photo diodes, wherein electron multiplication of the signal charge is performed in each of the vertical transfer paths; and a storage section that stores data indicating a multiplication factor of the electron multiplication, the multiplication factor being detected at each place of the vertical transfer paths in which the electron multiplication is performed. | 10-09-2008 |
| 20100321470 | IMAGING APPARATUS AND CONTROL METHOD THEREFOR - A pantoscopic imaging apparatus includes first and second imaging units. First and second images simultaneously captured by the respective imaging units are displayed as live-view images in a dual-screen fashion on an LCD. Overlapping areas between the first and second images, which overlap with each other when the first and second images are synthesized to produce a panoramic image, are detected. A distance of the nearest subject to the imaging apparatus is determined among those subjects contained in the overlapping areas. If the nearest subject distance is less a predetermined threshold value, the nearest subject is displayed in a specific pattern within each of the live-view images, to give an alert to a potential error that would be caused by parallax in the panoramic image before it is produced from the first and second images. | 12-23-2010 |
| 20110002544 | IMAGE SYNTHESIZER AND IMAGE SYNTHESIZING METHOD - Two camera assemblies in a multiple camera system output first and second images. In an image synthesizing method of stitching, an overlap area where the images are overlapped on one another is determined. Feature points are extracted from the overlap area in the first image. Relevant feature points are retrieved from the overlap area in the second image in correspondence with the feature points of the first image. Numbers of the feature points and the relevant feature points are reduced according to distribution or the number of the feature points. A geometric transformation parameter is determined according to coordinates of the feature points and the relevant feature points for mapping the relevant feature points with the feature points, to transform the second image according to the geometric transformation parameter. The second image after transformation is combined with the first image to locate the relevant feature points at the feature points. | 01-06-2011 |
