摘要： PURPOSE:To obtain an optional aspect ratio with high resolution by placing plural solid-state image pickup elements in shifting spatially the picture element by (1/2+m) times of a picture element interval in the horizontal or vertical direction. CONSTITUTION:For instance, two solid-state image pickup elements whose aspect ratio is 3:4 and whose number of picture elements is 500X400 are used, and one solid-state image pickup element is placed by shifting a picture by (1/2+m) in the horizontal direction, and shifting a picture element by 1/2 in the vertical direction. By varying (m) to 1-400, the aspect ratio can obtain an optional value of 3:4-3:8, and the number of picture elements in the horizontal direction of the center part and the number of picture elements in the vertical direction also go to two times, therefore, the resolution in the horizontal direction and the vertical direction of the center part can be raised.

摘要： PURPOSE:To reduce the vertical smear by extracting the light charge containing the vertical smear, etc. and the charge containing the vertical smear only after separating them from each other and carrying out the subtraction between both charges. CONSTITUTION:A pair of horizontal CCD(10,10'') are used to transfer an electric charge during a repetition mode of one of electrode pairs. In this case, horizontal switch transistors 81...8n and 8'1...8'n are used for two switching actions respectively. Then the light charge Q'V2 of the vertical smear appears at an output terminal 15 of the CCD10; while the light charge QS containing the vertical smear charge Q'V3 appears at an output terminal 15'' of the CCD10'' respectively. Then both output voltages are applied to a subtracting circuit 19 for subtraction. Thus it is possible to deliver a signal containing a small amount of vertical smear from an LPF20.

摘要： PURPOSE:To obtain a solid-state image pickup device having the capacity for expanding the dynamic range by providing nonlinearity to photoelectric converting section and changing the amount of signal charge storage depending on indoor or outdoor. CONSTITUTION:A photoelectric converting section of an inter-line CCD solid- state image pickup device is provided with a photo diode and an overflow drain and since an electric charge verflowed from the photo diode flows to the overflow drain through a gate, the electric charge flowing to the CCD from a transfer gate during the transfer of charge is eliminated thereby preventing blooming. A voltage controlling the overflow drain is obtained by changing over voltages Va, Vb by means of switch circuits 7, 8. This changeover is attained by using a Q output 11 and a Q' output 12 of a monostable multivibrator circuit 10 triggered by a vertical synchronizing pulse 9.

摘要： PURPOSE:To discontinue a reading action for an optional period and to ensure a free variation of shutter speeds by using also an optical shutter to control the supplying time of a driving pulse to a solid state image pickup element. CONSTITUTION:The optical image of an object is irradiated on an image pickup element 2 through a lens 1 and an optical shutter 15. A pulse 31 is produced when a shutter button 8 is pushed. A logical circuit 17 actuates a shutter time setting pulse generating circuit 18, and the circuit 18 produces a pulse 33 which decides the opening time of the shutter 15. The pulse 33 and a pulse 30 which decides the reading cycle are sent to a logical circuit 20 for production of a pulse 34. Then a driving pulse inhibiting circuit 21 is actuated to discontinue the reading action of the element 2 for a fixed period. It is regarded that an electronic shutter is obtained while the reading of the element 2 is inhibited.

摘要： PURPOSE:To reduce the vertical smear and to obtain a video signal with high quality, by transmitting a pseudo signal from a charge coupling element used for vertical scanning in a direction opposite to the transfer direction of a video signal at a vertical blanking period. CONSTITUTION:A photo diode 1 being photo sensing picture elements arranged in array horizontally and vertically is connected to a vertical transfer CCD3 via a transfer gate 2, and the vertical transfer CCD3 is connected to a horizontal transfer CCD4. The picture information stored on the photo diode 1 is transferred to the CCD3 with the impression of the pulse to gate lines 7, 8, 9, 10 and then to the CCD4. The vertical smear signal mixed in the CCD3 is eliminated by transferring the signal to a vertical smear signal sweep-out section 14 during the vertical blanking period by means of a sweep-out gate 15 independently of the turning on/off of the transfer gate 2.

摘要： PURPOSE: To simplify the control when the continuous snapshot is executed for several seconds or less and to reduce the power consumption, by revolving a motor for a fixed period after the recording is over.
CONSTITUTION: When a shutter 10 is pushed, a motor 5 is revolved by a motor control circuit 12. An optical shutter 7 is opened and closed after the number of revolutions of the motor 5 reaches a specified level. Then the photoelectric conversion is carried out by an image pickup element 8. The signal of the element 8 is read out, and the signals equivalent to a frame are sampled to be recorded to a magnetic head 4. In such a way, the shutter 7 is opened and closed after the number of revolutions of the motor 5 reaches a fixed level. This produces a delay of about one second for the first image. However it is possible to release the shutter without producing virtually any delay in case of the continuous snapshot by revolving the motor 5 for a specified period after the recording is over.

摘要： PURPOSE: To obtain a spatial frequency filter which supresses a false signal generated in an optical image pickup system which has a dot color separation filter, by arranging an optical plate such as a quarter-wavelength plate or rotary polarization plate between plural birefringence plates of the spatial frequency filter which are arranged in different directions.
CONSTITUTION: A figure shows an example of the arrangement of the birefringence plates and quarter-wavelength plate between a lens system 11 and an image pickup element 12. A false signal of color is mixed into a low frequency range about at a 3.58MHz spatial frequency (about 280TVs). The false signal of color is mixed into a low frequency range vertically at a spatial frequency corresponding to 525TVs. To suppress those false signals of color, two birefringence plates are set at such an interval that the shifting distances of an image is 23 and 13.5μm, i.e. about 3.9 and 23mm and while the former image shifting direction is set horizontal and the latter shifting direction is set vertical; and the quarter- wavelength plate 3 is arranged between them.
