Title: Photographing device
Inventor: OCHI KEIZO
IPC: H04N1/04
Filed: 1997-11-11
Abstract: PROBLEM TO BE SOLVED: To eliminate the deficiency of exposure when photographing by line progressive scanning or consecutive photographing by surface scanning is performed by an illumination controlling means making a light source emit light plural times each time an image pickup device performs an image pickup operation. SOLUTION: When light emission of a xenon lamp 91 starts, emitted light is partially made incident on a photosensor 96 and a detection signal S96 that corresponds to illumination intensity is inputted to a controller 191 through a photometry circuit 194. The controller 191 makes a switching signals SSW nonactive when the illumination intensity reaches upper limit value that is set in accordance with light emission quantity DL which is notified from a CPU 71. Thus, an output of a comparator 193 is inverted and a switching driver 192 turns off an IGBT 95. When the illumination intensity drops to lower limit value, the signal SSW is made active and after that, switching control of the IGBT 95 is performed so that the illumination intensity may be value within a set range, and light emission occurs in plural times while picking up the image of one line.

Abstract: PURPOSE:To reduce raggedness on the surface of an emitter region for a bipolar transistor by a method wherein a silicon film is deposited and is developed into a base electrode by anisotropic etching and then side-etching, which is isotropic, is accomplished for the formation of an undercut section in a first insulating film. CONSTITUTION:Side-etching is accomplished for the removal of an insulating film 6 from the ends at the sides of the active base region of a base electrode 7, an emitter region, and an emitter electrode forming region, for the formation of undercut sections 9. A silicon film 10 is formed on the whole surface of the substrate, covering the undercut sections 9. The silicon film 10 is converted into an insulating film 11 except on the undercut sections 9. A p-type impurity introduced into the base electrode 7 is diffused into the primary surface of an epitaxial layer 2 through the silicon film 10 retained on the undercut sections 9, which results in outer base p<+> regions 12. A process follows wherein the insulating film 11 is removed from regions for the active base, emitter, and emitter electrode, for the production of junction holes 13. P-type semiconductor regions 15 are formed, to serve as active regions, in the regions removed of the insulating film 11.

Filed: 1990-11-15
Abstract: PURPOSE:To obtain a video signal suppressing color bleeding by detecting the respective correlation of a luminance signal and a chroma signal and controlling a parameter K of a K times circuit while considering also the correlation between them. CONSTITUTION:The basic constitution of parameter K control circuits 7a and 16a is the simple addition of correlation detecting circuits 6 and 15, an S N detecting circuit 8 and a hysteresis output signal conventionally, since the information quantity of a luminance signal is thinner and more than the information quantity of a chroma signal, the circuit to weight and to double a correlation detecting signal is used in the parameter K for luminance signal control circuit 7a. Accordingly, noise removing in a strong electric field is improved. Besides, in the parameter K for chroma signal control circuit 16a, a switch to change over a parameter K for the chroma signal corresponding to the correlation of the luminance signal is used and when the correlation of the luminance signal is small, the correlation of the chroma signal is made small irrespective of the correlation detecting result of the chroma signal. Accordingly, this noise removing device to suppress color bleeding is obtained.
