摘要： An image sensing device that outputs a signal logarithmically proportional to the intensity of the incident light. The image sensing device makes use of a sub-threshold current flowing between the drain and source of a MOS transistor when the gate voltage is below the threshold voltage (above which the MOS transistor is nominally conductive and below which nominally non-conductive). Since the logarithmic conversion is done in the photosensing section of a solid-state image sensing device, the output from the device is already compressed and is easily handled by a small capacity CCD. Some output systems for the image sensing device of the present invention are also described.

摘要： At the start-up of an engine, the ignition timing and the air-fuel ratio are controlled to prevent overload onto the volume of ISC air and decreased torque and torque difference.The fuel condition based on the amount of ignition timing correction to inhibit rotational fluctuation during idling is determined and the fuel quantity based on the result is corrected.Right after an engine has started and until a pilot burner is created in the heat spot of the catalyst, the ignition retard control is mainly executed, and at the time when it is determined that a pilot burner has been created in the catalyst's heat spot, the lean air-fuel ratio control is to be executed instead of the ignition retard control. Furthermore, when the ignition retard control changes to the lean air-fuel ratio control, the state transition control is executed along the equivalent ISC air volume line so as not to cause torque fluctuation.

摘要： In an image-sensing apparatus, the shading data acquired when uniform light is shone on a sensor 1 is stored in a memory 3, and the temperature T0 of the sensor 1 detected by a temperature detector 6 at that time is stored in a calculation circuit 7. During image shooting, the temperature T of the sensor 1 is detected by the temperature detector 6 so as to calculate the temperature ratio T/T0 of this temperature to the temperature T0 stored in the calculation circuit 7. Then, a temperature compensation circuit 41 multiplies the shading data for the pixels that output image data by T/T0. A correction calculation circuit (COR) 4 subtracts the shading data thus multiplied by T/T0 from the image data, and thereby the unevenness in sensitivity among the pixels of the sensor 1 is corrected.

摘要： A solid-state image sensing apparatus includes a solid state image sensing device having a characteristic that an output voltage thereof natural-logarithmically varies in accordance with light reception amount. An image sensing output signal is obtained with respect to each pixel when uniform light is irradiated to the solid-state image sensing device. The difference is then calculated between an image sensing output signal obtained with respect to each pixel in actual sensing and an image sensing output signal with respect to a pixel corresponding thereto which signal is stored, to form an image signal.

摘要： Control device of an internal combustion engine that determines whether or not to perform sensor element heating control of an air-fuel ratio sensor with high accuracy based on the mass of condensed water in an exhaust pipe. The control device computes the rate of change of condensed water mass in an exhaust pipe based on the saturated water vapor pressure and the water vapor partial pressure of exhaust gas, and computes the rate of change of evaporation mass in the exhaust pipe based on the amount of heat which the condensed water receives in the exhaust pipe. The control device updates the mass of condensed water based on the rate of change of condensed water mass and the rate of change of evaporation mass, and determines whether or not to perform heating control by a heating controlling unit based on the updated mass of condensed water.

摘要： In a solid-state image-sensing device, when image sensing is performed, in each pixel, MOS transistors T1 and T5 are turned on and a MOS transistor T6 is turned off so that a MOS transistor T2 operates in a subthreshold region. When resetting is preformed, in each pixel, the MOS transistors T1 and T5 are turned off and the MOS transistor T6 is turned on so that the gate voltage of the MOS transistor T2 is kept constant. In this state, the MOS transistor T2 is brought first into a conducting state and then, by turning a signal φVPS to a high level, into a cut-off state. This permits a signal proportional to the threshold value of the MOS transistor T2 to be output as compensation data.
