Abstract: An image sensor 20A contains a photodiode array portion 21, a signal processor 22, a switching instruction part 23A and a control part 24A. Each switch SWn is provided between the corresponding photodiode PDn and the common output line L, and instructed to carry out the switching operation by the switching instruction part 23A so as to be closed, whereby the charges accumulated in the junction capacitance portion of the photodiode PDn are output to the common output line L. On the basis of the instruction from the switching instruction part 23A, the N switches SW1 to SWN carry out the switching operation so that the N switches SW1 to SWN are set to the close state in the different periods and the interval at which each switch SWn is set to the close state is equal to an integral multiple of a base period. As described above, the charge accumulation time of each of the N photodiodes PD1 to PDN is set to an integral multiple of the base period.

Abstract: A plurality of storage pixels within each unit pixel are arranged successively so that signal electrons for each storage pixel are moved independently through the storage pixels. Signal electrons newly generated in a photosensitive pixel are added to relevant signal electrons among the signal electrons moved independently through the storage pixels. That is, signal electrons generated in the photosensitive pixel for each of highly relevant frames are superimposed in the same storage pixel and stored in each storage pixel. The signal electrons stored in each storage pixel are subsequently amplified in and outputted from an output amplifier only once. Thus, read noise occurs only once at the output amplifier, to obtain images of high signal-to-noise ratio.

Abstract: This invention is to decrease the sensor pitch, prevent saturation by external light, accurately determine skimming, simplify skimming determination, and prevent any difference in influence of the transfer efficiency between the ON and OFF states. For this purpose, a distance measuring apparatus includes a light projection section for projecting light to an object, a sensor array for receiving reflected light from the object, a first transfer section for transferring charges from the sensor array, and a ring-shaped second charge transfer section for integrating the charges from the first transfer section, wherein the first charge transfer section transfers charges in a light projection ON state and charges in a light projection OFF state at a timing, the transfer frequency of the second charge transfer section is twice that of the first charge transfer section, and the timing of the first charge transfer section has a phase different from that of the second charge transfer section.

Abstract: A plurality of sensor portions detect a variety of physical characteristics of objects to be detected, which are being conveyed on a conveyance passage to asynchronously transmit electric signals indicating results of detection to a processing unit. The processing unit causes an A/D converter to A/D-convert the electric signals transmitted from the sensor portions. A mixer adds, to data, an identifier indicating the sensor portion from which data has been transmitted to sequentially output data for each of the sensor portions. A detection-result processing means receives data output from the mixer to identify the sensor portion from which data has been transmitted in accordance with the identifier contained in received data so as to perform a process for detecting the variety of the physical characteristics. The structure and circuit structure of the transmission passage in the detecting apparatus can be simplified.

Abstract: An image sensor includes a plurality of photosensitive pixel lines adjacent to each other in the sub-scanning direction, each of the photosensitive pixel lines having a number of photosensitive pixels arranged in the main scanning direction, and horizontal transfer registers disposed outside of the photosensitive pixel lines. A storage part for saving therein signal charges on a pixel-by-pixel basis is interposed between the photosensitive pixel lines and the horizontal transfer registers. Transfer of signal charges between the photosensitive pixel lines, storage part, and horizontal transfer registers are controlled by operating shift gates so that at a time point when exposure of the inside photosensitive pixel line has been finished, signal charges of the outside photosensitive pixel line is saved into the storage part to thereby secure a transfer passage for signal charges of the inside photosensitive pixel line.

Abstract: A device for producing an output voltage which is proportional to an applied magnetic field. The device includes a plurality charge injection regions, a corresponding plurality of charge exit regions, and a charge transfer region. The charge transfer region includes gate electrodes which serve to propagate at least one isolated charge packet across the charge transfer region in a predetermined direction from the charge input region to the charge output region. The charge packet is subject to the applied magnetic field which is perpendicular to the charge transfer region so as to induce a resultant potential that is orthogonal to both the applied magnetic field and the predetermined direction. Furthermore, the resultant potential effects a lateral redistribution of charge carriers in the packet. A recirculation configuration allows for a recycling of the packet from the output region back to the input region in order to accommodate a continuation of the redistribution of charge carriers.

Abstract: In the method of driving a solid-state image sensing device, for each vertical blanking (VBL), the signal charges of a first pixel group composed of photosensitive pixels of odd ordinal numbers counted in the vertical direction of the photosensitive region and the signal charges of a second pixel group composed of photosensitive pixels of even ordinal numbers counted in the same way are reversed in the vertical transfer direction, so that the signal charges of the first and second pixel groups can be outputted from the same charge detecting circuit for each field. Further, unnecessary accumulated charges in the pixel groups in the photosensitive region are cleared off in response to an accumulated charge clear pulse.

Abstract: 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.
