A photoelectric conversion device includes: pixels each including a photoelectric conversion unit and a counting unit generating a count value based on incident light to the photoelectric conversion unit; and a calculation unit performing interpolation processing on the count value. Each pixel is controlled to either a first state in which generation of the count value is enabled or a second state in which that is disabled. In a first sub-frame period, a first pixel is in the first state, and a second pixel is in the second state. In a second sub-frame period, the second pixel is in the first state, and the first pixel is in the second state. The calculation unit calculates a second count value of the first pixel in the second sub-frame period by performing the interpolation processing using a first count value generated in the second pixel in the second sub-frame period.

Photoelectric conversion device

Provided is an information processing device configured to generate a learning model for performing image recognition on a first image acquired by a first imaging device including an optical system having a first optical characteristic, including: a conversion unit configured to convert a second image for learning to generate a third image having a distortion characteristic based on the first optical characteristic; and a generation unit configured to generate the learning model based on the third image. The second image is an image acquired by a second imaging device including an optical system having a second optical characteristic different from the first optical characteristic.

Information processing device and information processing method

An imaging system comprises a whole image read out unit for reading out a whole image in a first resolution from an imaging device, a partial image region selecting unit for selecting a region of a partial image in a part of the whole image which is read out, a partial image read out unit for reading out the partial image in the selected region in a second resolution from the imaging device, a characteristic region setting unit for setting a characteristic region, in which a characteristic object exists, within the partial image, a characteristic region image read out unit for reading out an image of the characteristic region, which is set, in a third resolution from the imaging device, and a resolution setting unit for setting such that the first resolution&#x3c;the second resolution&#x3c;the third resolution.

Imaging system and imaging method

A solid-state image pickup apparatus includes rows and columns of pixels, each column or each set of a plurality of columns being provided with an analog-to-digital converter. When an operation for holding analog electric signals performed by the analog-to-digital converters is performed simultaneously with an operation for outputting data from memories holding digital signals that are output from the analog-to-digital converters, 'streaky noise' artifacts appear on an image obtained by such operations. To avoid this, the operation for holding the analog electric signals and the operation for outputting data from the memories holding the digital signals are set apart from each other by at least one data clock period of a scanning circuit.

Solid-state image pickup apparatus and method for driving solid-state image pickup apparatus

An electromagnetic driving device includes an armature, a pair of electromagnets disposed in an opposed relation to each other on opposite sides of the armature so as to be able to apply an electromagnetic attracting force to the armature, and a pair of return springs for biasing the armature toward the electromagnets, respectively. In the electromagnetic driving device, the energizing quantity for the electromagnets is varied in accordance with operational conditions. Thus, it is possible to insure the attracting and maintaining of the armature to and on the electromagnets irrespective of changes in operational conditions. In addition, the energizing quantity for the electromagnets is varied in accordance with the distance between the armature and the electromagnets. Thus, it is possible to avoid a wasteful consumption of electric power in the electromagnets to enable a reliable attracting and maintaining of the armature.

Energization control method, and electromagnetic control system in

In a valve operating system designed to open and close intake valves of an internal combustion engine by an electromagnetic force, a first electromagnetic driving device for electromagnetically driving a first intake valve capable of opening and closing a first intake valve bore and a second electromagnetic driving device for electromagnetically driving a second intake valve capable of opening and closing a second intake valve bore are controlled by a control device in a manner so that when the engine is in a predetermined operational state, the first intake valve is opened and closed in a condition in which the second intake valve has been closed and stopped. Thus, it is possible to produce a swirl equivalent to that produced by changing of the lift amount, to provide a reduction in consumed electric power and to achieve a reliable engine operation, e.g., starting.

Valve operating system for internal combustion engine

An SOHC-type valve operating system in an internal combustion engine having a single cam shaft commonly provided for a pair of intake valves and a pair of exhaust valves. A plurality of intake valve driving members are rockably disposed between the cam shaft and the pair of intake valves and have an operative-connection switchover mechanism for switching over the connection and disconnection of the intake valve driving members. A pair of exhaust valve driving members are rockably disposed between the cam shaft and the pair of exhaust valves and independently operate each of the exhaust valves. The operative-connection switchover mechanism includes a switchover pin movable between a position for operatively connecting adjacent intake valve driving members and a position for releasing such connection, which pin is slidably mounted in a cylindrical sleeve secured to the intake valve driving members for guiding the movement of the switchover pin. The cylindrical sleeve also rotatably supports a cylindrical rotor in rolling contact with a cam provided on the cam shaft. The operative-connection switchover mechanism is disposed on the opposite side of the intake valves with respect to the rocking axis of the intake valve driving member whereby space for disposing a component such as an ignition plug is available on the intake side of the engine.

SOHC-type valve operating system in internal combustion engine

A valve operating device for an internal combustion engine having a drive rocker arm operatively associated with an intake or exhaust valve and a free rocker arm releasable from the intake or exhaust valve. The drive rocker arm and the free rocker arm are disposed adjacent to each other and operable selectively in mutually different modes according to the rotation of the camshaft. In one embodiment either the drive or free rocker arm has two arms connected together with one arm on each side of the other rocker arm for balanced loading. A selective coupling mechanism is disposed between the drive rocker arm and the free rocker arm for selectively connecting and disconnecting them with a coupling pin movable in a direction substantially normal to the axis of the rocker shaft.
