摘要： A digital video camera includes an addition circuit in which an offset set by a CPU is added to an output from an A/D converter. A clamp level calculation circuit calculates a clamp level on the basis of an average level of eight pixels included in each line within a back end OB (optical black) level detection area in a normal mode, or calculates a clamp level on the basis of an average level of two pixels included in each line within a front end OB level detection area in a quadruplication mode. A first subtraction circuit subtracts the clamp level from an output of the addition circuit so as to clamp the output of the addition circuit. An output of the first subtraction circuit is clipped at a zero-level by a zero-clipping circuit, and an output of the zero-clipping circuit is applied to a second subtraction circuit through a low-pass filter, whereby the same offset can be subtracted from the output of the zero-clipping circuit.

摘要： A video camera (10) includes a microcomputer (26) which determines whether each of detection areas defined within an image field (44) is valid or invalid. If there is a valid detection area, luminance addition data and color addition data are evaluated by an addition data generating circuit (46) for each of addition regions of 64, for example, which are defined by dividing the image field (44). Differences of the addition data between a given addition region and a left adjacent addition region in a horizontal direction and an upper adjacent addition region in a vertical direction are evaluated, and the differences are compared with predetermined values. If comparisons satisfy predetermined conditions, a count value is incremented. On the basis of a total count value of the horizontal direction and a total count value of the vertical direction, it is determined whether or not an object is an object having repeated pattern, and a whole motion vector V.sub.n is evaluated by methods being different from each other according to a determination result. Then, an integration vector S.sub.n is evaluated according to a status of the video camera, whereby a blurring of an image due to an unintentional motion of the video camera can be corrected.

摘要： A motion vector detection circuit includes a single representative point memory into which representative point data at a preceding frame of all of a plurality of detection blocks formed in a motion vector detection area in an overlapped manner are written. All pixel data at a current frame of the motion vector detection area are written into a single pixel memory. The representative point data are selectively read-out from the representative point memory, and the pixel data of a detection block corresponding to the selected representative point data are read-out from the pixel memory. Then, correlation of the selected representative point data between the pixel data is determined by a correlator, whereby a motion vector can be detected. Since all the representative point data and all the pixel data in the motion vector detection area are respectively written into the representative point memory and the pixel memory, it is possible to reduce the number of components and a cost.

摘要： In a refrigerator, the inner space of a heat insulated housing is divided to form a refrigerating compartment, a freezer compartment, and a vegetable compartment. A projection which contacts with the back of a cooler cover and divides the space behind the cooler cover into two chambers arranged in a lateral direction is formed on a back wall portion. The space enclosed by the projection, the cooler cover, and the housing is formed as a cold air passage for guiding cold air of the refrigerating compartment to the vegetable compartment. A damper device has a shutter plate, a bias spring which urges the shutter plate toward a cold air duct, and a shape memorizing alloy coil spring on which a heater is wound. A weak current is always supplied from a damper control device to the heater so that the temperature of the shape memorizing alloy coil spring is maintained at the Ms point (martensite phase transition start temperature) or higher under the state where the shutter plate is lifted up. A defrosting control device for controlling the electric power supply to a defrosting heater has an operation integrating counter for integrating the operation time period of a compressor, converting means for converting the open/close frequency of doors into a time period, and a door-closure counter for measuring a time period of a door-closure state.

摘要： Auto focus control and/or auto exposure control is carried out by using a luminance signal before gamma correction, before addition of aperture signal but after hand shake correction. Auto white balance control is carried out by using a color signal after hand shake correction. Consequently, precise auto focus control, auto exposure control and/or auto white balance control can be done. The field memory for electronic zooming and/or hand shake correction is also used as a field memory for noise reduction. Consequently, a video signal processing circuit which is inexpensive and simple can be implemented.

摘要： A controlling device for controlling the transmission ratio of a non-stage transmission in a vehicle. The transmission ratio is controlled according to a forecast output power of the vehicle. The output power is forecast based on an operating condition of the vehicle, such as atmospheric pressure. The control considers various operating parameters. A comparison of a predetermined ratio of increase of engine speed or throttle opening with actual ratios of increase of engine speed or throttle opening may be made in controlling the transmission ratio. An uneven road surface is detected and a transmission ratio of the transmission is controlled accordingly to substantially eliminate hunting. An engine speed is controlled so that the engine speed may not exceed a predetermined rotational speed when the transmission gear ratio is fixed. A target engine speed or target transmission ratio is corrected in response to an output signal of a comparison device which compares an actual vehicle velocity with a set vehicle velocity during automatic fixed vehicle velocity running.

摘要： An apparatus for measuring a flow of intake air to an engine includes a bridge circuit including a heat resistor placed in an intake air path of the engine, a resistor for sensing the temperature of the intake air, and a plurality of balance resistors. A heating current is supplied to this bridge circuit through a transistor controlled by a periodical current-passage control signal generated by a microcomputer. A signal Vh, representing a temperature change of the heat resistor heated by the heating current, is detected by the microcomputer. A first correction value is computed by using a difference between the detected value from the microcomputer and a signal Vho, representing temperature of the heat resistor when the bridge circuit is balanced at normal temperature. A time width correction value .DELTA.Do1 is computed from a table on the basis of the first correction value. The correction signal .DELTA.Do1 is used for correcting the current passage time. The current passage time width as corrected is used for computing a flow of the intake air.
