摘要: A CCD output signal reproduction apparatus is applied to a solid state image sensor that performs a swing-driven image pickup operation. This image sensor is synchronized with one frame period and swings periodically and relatively in relation to incident light to pickup the image while changing the sampling positions in the A and B field periods. The carrier generator produces first and second sinusoidal carrier signals which have the same frequency as that of the read out frequency of the image sensor. An amplitude modulator modulates the carrier signals in response to the waveforms of the image signals supplied from the image sensor. Accordingly, amplitude-modulated A, B field image signals, which are phase-shifted by half the pixel pitch of the pixel arrangement of the image sensor. A carrier clamp circuit forcibly clamps the different peak potentials of the carrier waveforms of the amplitude-modulated field image signals to the reference potential level. In this way, when the field image signal whose waveform has been shaped is synthesized on the reproduction screen, it is possible to obtain a one frame image which has a resolution twice that determined by the actual number of pixels.

摘要: A color image sensing system includes a CCD image sensor with an optical color filter. A CCD driver is provided to electrically drive the image sensor, which is attached to a vibration table serving as a swing-driver for moving the image sensor along a horizontal direction such that each cell of the image sensor shifts, in a frame period including first and second field periods, between four different sampling positions substantially aligned in the horizontal direction. During each field period, each cell is positioned at two sampling positions, wherein a brightness signal component is produced at one sampling position and color signal components are produced at these sampling positions. The distance between two sampling positions at which the brightness signal components of the first and second field images are produced is set to be half the horizontal pitch of the cells of the image sensor. The remaining two sampling positions of the four sampling positions are apart from each other by one-and-half times the horizontal cell pitch. A color frame image is thus reproduced by electrically adding the first and second field images to increase the number of picture elements to more than the actual number of cells, thereby improving the horizontal image resolution of the frame image and minimizing the generation of color moire in the frame image. The swing-drive operation of the image sensor is repeated in synchronism with the frame period.

摘要: A solid-state image sensing device, such as an interline-transfer type charge-coupled device (IT-CCD), produces signal carriers in response to incident light and generates an image pickup signal. One frame of the image signal is formed of two fields. The CCD chip is coupled to fixed bimorph piezoelectric vibrators by which it is given a wobbling-swing drive during image pickup. This wobbling-swing drive is controlled by a vibration controller. This vibration controller controls the vibration mode of the bimorph piezoelectric elements to apply a first vibration (swing vibration) to the CCD such that each pixel cell is displaced to a different sampling position in the plurality of field periods included in one frame period for image pickup, and applying a second vibration, i.e., a swing vibration with wobbling superposed, to the CCD such that each pixel cell is wobbled while picking up an image in each sampling position, which is positioned in each field period.

摘要: A solid-state image sensing device such as an interline-transfer type charge coupled device generates signal charges in response to incident light to produce an image signal. The CCD output signal includes a mixed reset pulse component from a reset pulse driver to the IT-CCD, as well as an image signal component corresponding to the signal charges. When the IT-CCD contains a defective picture element, position data of the defective picture element is stored into an address memory. An amplitude controller detects an increment of a signal level corresponding to a dark current generated at the defective picture element, and temporarily decreases the amplitude of the reset pulse only when the image signal is output from the defective picture element. In this way, the mixed reset pulse contained in the image signal output from the defective picture element is reduced, thereby subtracting the signal level increment from the CCD output signal produced from the defective picture element.

摘要: A solid-state image sensor has an electrically floating carrier detecting electrode formed on a substrate, into which the signal carriers are transmitted, a sense amplifier circuit detecting the variation in a voltage of the electrode at the time of transferring the carriers, and a resetting electrode for resetting the potential of the electrode to a predetermined potential at every read-out period of the picture element section. A circuit arrangement for removing noise is provided to have two switches which switch to alternatively become conductive in response to control pulse signals. The first switch becomes conductive during a first period within one picture element period. During the first period the CCD output signal contains an effective image signal component. The second switch becomes conductive during a second period during which the CCD output signal contains a reset noise component, thereby forcibly fixing the level of the reset noise signal to a DC reference potential so that reset noise can be removed.

摘要: In an image sensing system, a solid-state image sensor is mounted on a vibration stand in a manner as to vibrate horizontally to an incoming light in synchronization with one frame period, thereby sensing while alternatively displacing at different sampling positions in two field periods. Field image signals from the image sensor is supplied, through a signal processor, to a signal reproduction unit which includes a carrier generator for producing first and second carrier signals having the same frequency as the horizontal readout frequency of the image sensor and a phase in reverse to one other in the field periods, and an AM modulator for amplitude-modulating the carrier signal. The amplitude modulation field signals thus obtained are sliced at a suitable level by a slicer and then synthesized each other to obtain a frame image signal.

摘要: A solid state image sensor has a photosensing region formed on a substrate. The photosensing region has a plurality of photocells for receiving an incident image. The photosensing region is capable of changing image sampling modes by relatively shifting image sampling points for the incident image. In the photosensing region, a plurality of first transfer elements are formed and the first transfer elements receive the signal charges from adjoining photocells and transfer them out. Further, a temporary storage region is formed on the substrate having a plurality of second transfer elements therein for each of the first transfer elements. Each of the second transfer elements has a capacity to accommodate all of the signal charges of a corresponding first transfer elements which are read out from the photocells at the same time. A plurality of gate elements are respectively formed between each of the first transfer elements and their corresponding plurality of second transfer elements. Each gate elements changes transfer direction from one of the first transfer elements between at least two of the second transfer elements based on the sampling mode for the incident image. Third transfer elements are formed adjacent to the temporary storage region. The third transfer elements repeat a readout cycle of receiving the signal charges from a plurality of second transfer elements and then transferring them out.
