摘要:
A phase difference detector of the type capable of distinguishing a focused state by detecting relative positions of a pair of optical images obtained from an object, comprises sensor means adapted to photoelectrically convert the pair of optical images and to output a first analog electrical signal corresponding to one of the optical images and a second analog electrical signal corresponding to the other optical image, the signals being generated by the photoelectric conversion, at a predetermined period and in a non-destructive manner, and analog arithmetic means for subjecting the pair of analog electrical signals output from the sensor means to a correlative arithmetic operation.

A various CCD delay element in which extra delay stages are provided. The extra stages are either held at a given potential to pass all signals therethrough and thus to not contribute to the gain or are connected to the clock signals to thereby increase the delay.

A phase-difference detector for use with an auto-focus detecting apparatus of camera. The detector comprises a means for creating correlative values which exhibit outstanding characteristics that makes it possible to ascertain the maximum and minimum values. The detector is capable of detecting a phase-difference with high accuracy.
摘要:
A horizontal transfer section for a solid state image-pickup matrix, in which the parallel signals are first read by a first horizontal CCD. A second horizontal CCD is aligned in parallel with the first one and having a deeper potential well. A gate electrode separates the two CCDs. Thereby, the gate electrode can transfer charges from the first to the second CCD and the first CCD can be refilled with different signals. The two horizontal CCDs can be serially read out by common clocking signals.

An automatic focusing adjusting device for use in a camera is disclosed in which an operation processing on the phase difference detection to be executed when the focusing of an image pickup optical system is detected can be performed by means of an analog signal processing. In the automatic focusing adjusting device, when the distance measurement ranges in a light receiving part of sensor means are specified by operation means, then control means controls charge input preventive means in such a manner that only the signal electric charges that are stored in photoelectric conversion elements forming the light receiving part but belonging to the other distance measurement ranges that the ranges specified by the operation means are prevented from flowing into a readout part in the sensor means, whereby the distance measurement ranges in the light receiving part of the sensor means can be changed. Also, in the adjusting device, based on the output signal of the operation means or on the distance measurement information obtained from the sensor means, the distance measurement ranges in the light receiving part of the sensor means can be changed and the changed versions of the distance measurement ranges can be visibly displayed on display means.

摘要:
A solid-state image pickup apparatus of a charge transfer type includes a solid-state imaging device having an array of photosensitive cells with charge divider paths provided for sequentially receiving charges generated in the cells of a horizontal line to divide the charges into two groups for each pixel. For one of the two fields subjected to interlace scanning, charges generated in the cells of odd-numbered lines are transferred to its output port, and one of the two groups of charges for even-numbered horizontal lines adjacent to odd-numbered horizontal lines are discharged. Then, the output port effects addition with weight on the charges from the cells of the odd- and even-numbered lines to produce video signals of the odd-numbered lines. For the other field, on the other hand, charges generated in the cells of even-numbered lines are transferred to the output port, and one of the two groups of charges for odd-numbered horizontal lines are discharged. The output port in turn effects addition with weight on the charges from the cells of the even-numbered lines thus obtained to those of odd-numbered lines previously received to produce video signals of the even-numbered lines. Field flickering is adequately reduced and horizontal resolution of a picture is improved.
摘要:
An imaging apparatus includes a solid state imaging device in which pixels are arranged in a matrix. Row transfer lines and column transfer lines are each sequentially scanned so that video signals are delivered time-serially from the respective pixels to an output terminal. The row transfer lines are selected by a CTD which is scanned by drive pulses to sequentially and cyclically transfer charges therethrough. Gates associated with the CTD select one of the row transfer lines at a time responsive to a potential which is developed by the charges. The column transfer lines are selected by a shift register which addresses selection gates associated with the respective columns one after another responsive to a clock. The CTD may be assigned to the column transfer lines and the shift register to the row transfer lines. The apparatus is applicable even to a solid state photosensor arrangement made up of an array of photosensor elements in which case only one of the row transfer lines will be used.
