  • Publication number: 20110058083
    Abstract: 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.

  • Patent number: 7889259
    Abstract: An image pickup apparatus has an image pickup device including an imaging section, in which signal charges read out from plural photosensitive cells are vertically transferred over vertical transfer paths and the transferred signal charges are in turn horizontally transferred over a horizontal transfer path, which has a branching section for assigning the transferred signal charges to plural output channels, i.e. plural horizontal transfer paths provided at the end of the horizontal transfer path. A temperature sensor for detecting the temperature of the image pickup device is provided on the imaging section, and a temperature-induced drift compensator corrects a transfer error of signal charges in the image pickup device. The compensator modifies transfer error correction based on the detected temperature. The image pickup apparatus can thus substantially reduce an assignment error even when the temperature of the image pickup device changes.

  • Publication number: 20110002544
    Abstract: 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.

  • Publication number: 20100321470
    Abstract: 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.

  • Patent number: 7839443
    Abstract: 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.

  • Patent number: 7710485
    Abstract: A solid-state image pickup apparatus may improve, depending on the shooting condition, image degradation such as white balance offset or color mixture. An output scheme determiner defines, depending on shooting conditions such as shooting and sensitivity modes, output schemes such as the number of operative output circuits in an image sensor and a drive frequency of a horizontal transfer path. Depending on an output scheme, the vertical and transfer paths and output circuits in the image sensor are controlled, and one image sensing area is divided and the transfer rate of the horizontal path is reduced accordingly to produce an image signal. The determiner defines, in high sensitivity mode, the output scheme having a higher number of operative circuits and lower drive frequency. The apparatus may improve, without losing the high-speed reading, the horizontal transfer efficiency to avoid the transfer degradation and produce images free from degradation.

  • Publication number: 20100026860
    Abstract: After an end of exposure, a data level of OB signals that are imaging signals output from OB portion 400 are sampled by a CDS circuit 6 twice, to artificially generate two OB signals from each OB signal. Thereby, assuming that the total number of OB signals required to stabilize the black level in the clamp circuit 9 is n, the black level can be stabilized before it is started to output effective signals that are imaging signals from effective pixel portion 200 even if the number of OB signals output from the OB portion 400 is 1/n (in the case where pixel mixing or pixel thinning is performed, or in the case where the number of photoelectric conversion elements in the OB portion 400 is less than n). Accordingly, it is possible to prevent the image degradation by suppressing a wrong black level.

  • Patent number: 7643079
    Abstract: In a control circuit for controlling a solid-state image pickup device, two sorts of image data are read out separately with differing sensitivities. A timing generator control in a digital camera controls a timing signal generator to the interlace scanning or to all-pixel scanning, and outputs a timing signal, consistent with this control, to the driver. The driver outputs a driving signal, consistent with the timing signal, to the solid-state image pickup device included in an image pickup unit to read out signal charges. In particular, in interlace scanning, readout of signal charges of main pixels of the image pickup device is separated from that of subsidiary pixels of the device.
