Devices and methods for reducing parallax in graphic content captured by a camera array include identifying color fringes that correspond to the parallax in the captured graphic content, determining an amount of displacement of the color fringes and adjusting the parallax in the captured graphic content based on the amount of displacement. The camera array may comprise a two-dimensional array of cameras.

A controlling section 6, by bringing readout switches SW 1 of respective pixels P m,n that compose a certain row out of the M rows into a connected state, causes charges generated in the row to be input to integration circuits S n , causes first holding circuits H O1,n to hold voltage values output from the integration circuits S n , and then brings transfer switches SW 32 into a connected state to transfer the voltage values to the second holding circuits H O2,n , and thereafter performs in parallel an operation for causing the voltage values to be sequentially output from the second holding circuits H O2,n and an operation for, by bringing readout switches SW 1 of respective pixels P m+1,n that compose another row out of the M rows into a connected state, causing charges generated in the row to be input to the integration circuits S n . Accordingly, a solid-state imaging device and a method of driving a solid-state imaging device capable of suppressing variations in output characteristics, while solving the problem due to a delay effect are realized.

A distance image sensor capable of enlarging the distance measurement range without reducing the distance resolution is provided. A radiation source 13 provides first to fifth pulse trains P T1 to P T5 which are irradiated to the object as radiation pulses in the first to fifth frames arranged in order on a time axis. In each of the frames, imaging times T PU1 to T PU5 are prescribed at points of predetermined time ”T PD from the start point of each frame, also the pulses P T1 to P T5 are shifted respectively by shift amounts different from each other from the start point of the first to fifth frames. A pixel array 23 generates element image signals S E1 to S E5 each of which has distance information of an object in distance ranges different from each other using imaging windows A and B in each of five frames. A processing unit 17 generates an image signal S IMAGE by combining the element image signals. Since five times-of-flight measurement are used, the width of the radiation pulse does not have to be increased to obtain distance information of the object in a wide distance range, and the distance resolution is not reduced.

A radiation imaging apparatus comprises: output means (202,203) for outputting an analog signal for each pixel circuit by sampling and holding an electrical signal converted from radiation; and selection means (131-138, 108) for sequentially selecting positions of pixel circuits which output the analog signals, wherein after the output means outputs the electrical signals corresponding to a predetermined number of pixel circuits as analog signals, the selection means stops the selection and the output means stops the output in accordance with the stop of the selection.

In an imaging apparatus with shake correction function, an erroneous shake correction operation is prevented from being performed due to a front curtain shock. A shutter selecting section 625 determines that the current state is the shake-correction execution mode when a shake correction switch 313 is ON, when a tripod detection sensor 185S tripod is not mounted, when a shake amount equal to or larger than a predetermined value is detected by a shake detection sensor 171, and when a shutter speed is lower than a predetermined value. In this case, the shutter selecting section 625 selects an electronic focal plane shutter as the front curtain, and supplies an operation command signal to an electronic focal plane shutter control section 627. On the other hand, in cases other than the above-mentioned case, the shutter selecting section 625 determines that the current state is not the shake-correction execution mode, and selects a mechanical focal plane shutter as the front curtain and supplies an operation command signal to a shutter drive control section 73A.

An image shooting unit 21 generates an image signal Spa having an image shooting frame rate. A frame addition unit 41 performs frame addition on the image signal DVb having the image shooting frame rate. Control unit 61 controls drive unit 71 and the frame addition unit 41 based on a frame rate setting signal RSF from operation unit 62, and controls a variation of the image shooting frame rate in image shooting unit 21 and/or a switch of the number of additive frames in the frame addition unit 41, thus allowing an image signal DVj having a desired frame rate to be output from the frame addition unit 41. Thus, increasing the additive frame in number even without decreasing the image shooting frame rate at a low-speed shooting of the image allows such an image signal DVj shot at the low speed to be obtained.

There is provided a solid-state image pickup element capable of reducing the number of pixels at least in the horizontal direction and rapidly outputting a preferable video signal without causing moire or a false signal. The solid-state image pickup element includes: a vertical transmission section (3) for transmitting signal charge read from a photoelectric conversion section (2) of 2-dimensional arrangement one by one stage in the vertical direction; a horizontal transmission section (4) for transmitting the signal charge received from the vertical transmission section (3) in the horizontal direction; and a control section for controlling the transmission operation of the vertical transmission section (3) and the horizontal transmission section (4). The vertical last stage in the vertical transmission section (3) has the same transmission electrode configuration for every 2n+1 (n is an integer not smaller than 1) columns and a transmission electrode independent from the other vertical last stages is provided in the vertical last stages excluding one column or all the vertical last stages among the 2n+1 columns.
