摘要： A burst reading memory section (200) and continuous reading memory section (210) are independently provided for each of the two-dimensionally arrayed pixels (10). The burst reading memory section (200) has capacitors (25001-25104) capable of holding a plurality of signals. The continuous reading memory section (210) has only one capacitor 213. Signal output lines for the two memory sections are separately provided. When a signal produced by photoelectric conversion at the pixel (10) is outputted on a pixel output line (14), the signal can be simultaneously written in the capacitors at both memory sections (200, 201), after which the signals can be separately extracted to the outside at different timings. Therefore, a series of images taken at extremely short intervals of time during a short period of time can be obtained at an arbitrary timing without impeding a continuous image-acquiring operation at a low frame rate. Accordingly, both an ultrahigh-speed imaging operation having a limitation on the number of frames and an imaging that is rather slow but has no limitation on the number of frames can be simultaneously performed.

摘要： A pixel output line is provided for each of the pixels two-dimensionally arrayed in a pixel area. The pixel output lines are extended to a memory area, and a memory unit is connected to each of those lines. The memory unit includes a writing-side transistor, a reading-side transistor and a plurality of memory sections for holding signals for 104 image frames. A photocharge storage operation is simultaneously performed at all the pixels, and the thereby produced signals are outputted to the pixel output lines. In the memory unit, with the writing-side transistor in the ON state, the sampling transistor of a different memory section is sequentially turned on for each exposure cycle so as to sequentially hold a signal in the capacitor of each memory section. After a burst imaging operation is completed, all the pixel signals are sequentially read. Unlike CCDs, the present device does not simultaneously drive all gate loads, so that it can be driven at high speeds with low power consumption. Thus, the burst imaging can be performed at higher speeds than ever before.

摘要： A pixel output line (14) is independently provided for each of the pixels arranged in a two-dimensionally array within a pixel area so that pixel signals can be sequentially written in a plurality of memory sections (22) through the pixel output lines (14). When a plurality of frames of pixel signals are held in the memory sections (22), the pixel signals corresponding to two arbitrarily selected frames are read and respectively stored in sample-and-hold circuits (61 and 62), and their difference is obtained. Then, the difference signals corresponding to a predetermined range of the image are integrated, and the integrated value is compared with a threshold. If the integrated value exceeds the threshold, it is presumed that a change in an imaging object has occurred, and a pulse generation circuit (66) generates a trigger signal. By controlling the discontinuation and other imaging actions according to this trigger signal, it is possible to correctly take high-speed images of the situation before or after the occurrence of an objective phenomenon.

摘要： An independent pixel output line (14) is provided for each of two-dimensionally arranged pixels (10) within a pixel area (2a). A plurality of memory sections are connected to each pixel output line (14). In a continuous reading mode, photocharge storage is simultaneously performed at all the pixels, and signals are collectively transferred from the pixels (10) through the pixel output lines (14) to the memory sections, after which the signals held in the memory sections are sequentially read and outputted. In a burst reading mode, the operations of simultaneously storing photocharges at all the pixels and collectively transferring signals from each pixel (10) through the pixel output line (14) to the memory sections are sequentially performed for each of the memory sections to hold signals corresponding to a plurality of frames. When a imaging halt command is given, the holding of new signals is halted, and a plurality of frames of image signals held in the memory sections at that point in time are sequentially read and outputted. Thus, both an ultrahigh-speed imaging operation with a limitation on the number of frames and an imaging mode that is rather slow but has no limitation on the number of frames can be performed.

摘要： A floating diffusion (331) is created substantially at center of the light-receiving surface of an embedded photodiode (31), with a gate electrode of a transfer transistor (32) surrounding the floating diffusion. The concentration (or depth) of impurities in a p+-type semiconductor region, n-type semiconductor region or p-well region is changed in an inclined form so that a potential gradient being inclined downwards from the circumference to the center is created when an appropriate bias voltage is applied to the pn junction. The photocharges produced by incident light are rapidly moved along the potential gradient toward the center. Even in the case where the photocharge storage time is short, the photocharges can be efficiently collected since the maximum moving distance from the circumference of the photodiode (31) to the floating diffusion (331). Thus, the photocharges produced by the photodiode (31) are efficiently utilized, whereby the detection sensitivity is improved.

摘要： A surface acoustic wave filter device in which a capacitative coupling means is provided to couple at least one of the terminals of the SAW input transducer to at least one of the terminals of the output transducer, in order to equalize the levels of signals which are induced on the pair of output terminals of said output transducer without assuming the form of surface acoustic waves. The stray inductive coupling which normally occurs between the input and output terminals of the SAW filter degrades filter performance. Since the inductive coupling to the two output terminals is normally unequal, the inductively coupled unfiltered signals cannot be completely rejected by a balanced differential amplifier. By equalizing the levels of unfiltered signals at the output terminal, effective rejection by a differential amplifier is possible.

摘要： A transistor (24) which acts as a load-current source for a source follower amplifying transistor (22) for outputting a pixel signal to a pixel output line (40) is provided in each picture element (10), whereby a high bias current is prevented from passing through the high-resistance pixel output line (40), so that a variation in an offset voltage among picture elements is suppressed. Inclusion of the high-resistance pixel output line (40) into the source follower amplification circuit is also avoided, whereby the gain characteristics are prevented from deterioration. Thus, the S/N ratio of the picture element is improved so as to enhance the quality of the images.

摘要： A floating diffusion region is formed at an edge of a light-receiving surface of an embedded photodiode, with a transfer gate electrode located therebetween. A first region, with radially extending portions centered on the FD region, and a second region, located to the outside of the first region, are created in the substantially sector-shaped light-receiving surface. A dopant whose conductivity type is the same as the signal charges to be collected in the first region are introduced, whereby an electric field for moving the signal charges from the radially extending sections towards the center is created due to a three-dimensional field effect. As a result, the charge-transfer time is reduced. Additionally, since a circuit element in the subsequent stage can be placed adjacent to the floating diffusion region, the parasitic capacitance of the floating diffusion region can be reduced and a highly sensitive element can be obtained.
