Abstract: PROBLEM TO BE SOLVED: To provide an imaging apparatus capable of obtaining an image signal on which the revision of the setting of a signal processing operation is correctly reflected when frames are summed to vary the frame rate. SOLUTION: A pre-process section 14 uses an image signal DVa generated by imaging an object to carry out signal processing operations. A frame summing processing section 15 sums frames of an image signal DVb obtained through the signal processing operation by the pre-process section 14 to generate an image signal DVc whose frame rate is varied. When the signal processing operation of the pre-process section 14 is revised, the signal processing operation is revised in the unit of a frame summing period by a frame summing processing section 15 on the basis of a discrimination signal TW denoting the frame summing period.

Abstract: PROBLEM TO BE SOLVED: To correct gradation without deteriorating the contrast by obtaining a correction coefficient from the decision results of an area to which separated luminance data belong and correcting pixel value. SOLUTION: The arithmetic circuit 9 of a gradation correction circuit 8 generates luminance data y(i, j) and color data c(i, j) from image pickup results VT (x(i, j)). An area decision filter 10 decides an area to which the separated luminance data y(i, j) belong. A coefficient calculation circuit 11 generates a contrast correction coefficient g(i, j) in accordance with the signal level of a low frequency component r(i, j). A multiplication circuit 12Y corrects and outputs the signal level of the image pickup results VT by the luminance data according to the contrast correction coefficient g(i, j), and a multiplication circuit 12C similarly corrects and outputs the signal level of the results VT by the color data. An arithmetic circuit 13 converts luminance data y'(i, j) and color data c'(i, j) where gradation is corrected by the correction of a signal level into original image data x'(i, j) and outputs it.

Abstract: PURPOSE:To reduce the number of the sensors used, to simplify the structure, and to make the device inexpensive, as compared with a device in which a vibrator sensor, or an optical sensor, is used, by detecting both the upper limit and the lower limit of the powder storage quantity in a powder storage tank by an ultrasonic sensor. CONSTITUTION:A powder supply port 2 is provided at the center of an upper wall 1a of a powder storage tank 1, and an inverted cone shaped cyclone 15 is connected to an upper portion of this powder supply port 2. A single ultrasonic sensor 25 is mounted, slantwise downwardly, to the upper wall 1a of the storage tank 1. The ultrasonic sensor 25 is inclined at an angle permitting an ultrasonic wave 25b to be applied from a slantwise downwardly directed sensor face 25a toward a substantially central part of the tank 1 interior. The ultrasonic wave 25b is applied from the ultrasonic sensor 25 slantwise to a substantially central portion of a powder surface 4a constituting an upper surface of a powder 4 storaged Within the powder storage tank 1 and the return time length (pulse) of the reflected wave is measured, thereby always to detect the height of the powder surface 4a.
