Abstract: A diagnosis device is intended for an internal combustion engine including a supercharger, a blow-by gas passage that communicates between a portion of an intake passage and a crankcase, a PCV pressure sensor that detects a PCV pressure in the blow-by gas passage, and a crankshaft. The device executes specifying a specific period for which the amount of fluctuations in the intake air amount per unit time is a prescribed value or more on condition that the intake air amount is a determination air amount or more, calculating the amount of fluctuations in the PCV pressure during the specific period, and determining, based on the amount of fluctuations in the PCV pressure, the presence of an abnormality in the blow-by gas passage. The device sets the determination air amount to a smaller value when the rotational speed of the crankshaft is high than when the rotational speed is low.

Abstract: A mode setter 92 causes a shake sensor controller 43 and a shake amount detector 51 to execute a routine of low-speed control when the switch S1 is ON, and a routine of high-speed control when the switch S2 is ON. A display signal generator 121 generates a display signal based on the shake amounts obtained through a prescribed number of detections by the shake amount detector 51. A display 122 has multiple types of LEDs that illuminate in response to a display signal generated by the display signal generator 121 when the switch S1 is ON.

Abstract: A camera capable of shake correction, and is provided with: a sensor for sensing a light image of an object to detect a camera shake; an exposure time setter for setting a first exposure time based on a brightness of an object and a second exposure time smaller than the first exposure time; and a controller for judging as to whether the shake correction is disable, and controlling exposure with reference to the second exposure time when the shake correction is judged to be disable.

Abstract: A camera having a substitute shake amount calculator 51e that, where flash light is emitted while integration is being performed by a shake sensor, seeks a substitute shake amount using past shake amounts stored in a memory 56 instead of the shake amount sought from the image data obtained during this integration period.

Abstract: Method and apparatus for collecting image data of a picture by sampling N points of picture signals N times on each of a plurality of scanning lines, and converting the signal obtained at each of the sample points into digital signals characterized by sequentially sampling K different frames or portions of the picture by sampling for each frame M points of each line such that no sample points overlap and the data for one picture is collected by scanning K frames.
