摘要： In an CCD image sensor, when an image of a partial area is used, a frame rate is enhanced. Horizontal transfer of signal charges of an i-th line read out to a horizontal transfer portion is stopped at the time point when all or a part of a tail portion 74 subsequent to an extraction target portion 72. Under this state, the signal charges of an (i+1)-th line are transferred to the horizontal transfer portion. Thereafter, the horizontal transfer is started. Through this operation, unnecessary signal charges of the tail portion 74 of the i-th line and unnecessary signal charges of a head portion 82 of an (i+1)-th line are combined. By partially overlapping adjacent lines with each other, the cycle number of horizontal transfer clocks required for the horizontal transfer per line can be reduced as compared with a normal operation, thereby enhancing a frame rate.

摘要： A method for reducing smear in video images generated by a frame transfer CCD imaging system having an array of charge coupled devices. The video images comprise successive image frames, each frame including an array of image pixels corresponding to the array of charge coupled devices. The pixel array has a plurality of rows and columns. Each frame is temporally separated from a next successive frame by an integration time interval during which light falling upon the array of charge coupled devices is integrated to produce integrated charge samples representative of image frame pixel values, and by a transfer interval during which the charge samples are transferred from an imaging area to a storage area.

摘要： A charge-coupled image sensor having adjacent image acquisition and image storage areas is described. Pixel transfer can take place from the image acquisition area to the image storage area and from the image storage area to an output register simultaneously and at different respective transfer rates. This allows the image transfer into the storage area to begin during the active field period, i.e. while pixels are still being transferred from the storage area into the output register. In a preferred embodiment this is achieved by partitioning the image storage area into a first and a second storage section which can selectively operate at the same or different transfer clocking rates.

摘要： In the method of transferring charges generated by signal charge generating sections in response to light, a signal charge existing under some transfer electrode of the plural charge transfer sections arranged in parallel to each other is transferred through one of a plurality of connecting sections formed under the transfer electrode corresponding to another charge transfer section among the plural connecting sections formed between the plural charge transfer sections, on the basis of a predetermined drive pulse; and when the charge is transferred to the other charge transfer section, a charge remaining at the primary charge transfer section is transferred from the primary charge transfer section to the other charge transfer section, through the other connecting section among the plural connecting sections, to combine the remaining charge with the signal charge previously transferred.

摘要： A solid state imaging apparatus which prevents occurrence of small aperture fading by diffraction of light and can control the amplitude level of an image signal within a prescribed range. The solid state imaging apparatus employs a solid state imaging element such as a CCD. When the level of an image signal outputted from the solid state imaging element exceeds a predetermined value, a driving motor is driven to effect adjustment of an iris. The capacitance of a variable capacitance diode provided in a voltage converting section of the solid state imaging element is controlled in accordance with the amplitude level of the image signal to control the voltage conversion efficiency of the voltage converting section of the solid state imaging element so as to fix the level of the image signal.

摘要： An electronic image stabilization method and apparatus has application for use in hand-held video camcorders. The electronic image stabilization apparatus, contained within the camcorder, comprises a definition television (HDTV) image sensor with photosensitive cells, a gimbaled lens configuration and signal processing circuitry. The lens configuration projects a subject image upon only a portion of the image sensor. As the hand-held camcorder is physically jittered, the lens configuration projects the subject image on a different portion of HDTV image sensor. A scanner circuit reads values from the cells, and a threshold circuit compares the values to a pre-determined threshold value. If the photosensitive cell value is greater, the the projected subject image in the larger HDTV image array is determined, only the photosensitive cells illuminated by the projected subject image extracted from the HDTV image sensor. As a result, jitter in the output image, caused by hand-held shakes, is reduce or eliminated.

摘要： In CCD arrangements, such as bidimensional image sensors, it is usual to provide the output register in the form of two (or more) horizontal registers. Via transverse connections between the horizontal registers, charge packets are transported from one horizontal register to the other horizontal register. In order to avoid delays during this transverse transport due to narrow channel effects, the clock electrodes of the first horizontal register adjoining the transverse connections are widened at the expense of adjacent clock electrodes. These widened electrodes may be in the trapezoidal form, as a result of which additional drift fields are induced below these electrodes.
