Title: Electronic still camera and strobo for electronic still camera
Inventor: OTA YOSHITAKA
IPC: H04N5/335
Filed: 1988-11-04
Abstract: PURPOSE:To avoid a picture of skipped white level or deformed black level by giving plural timing signals to a strobo within a pickup time of one frame at strobo pickup and applying electronic shutter operation on the way of at least one lighting in each lighting so as to adjust the quantity of light reception. CONSTITUTION:A strobo is lighted at each of exposure periods split into 5. Then the intensity of strobo lighting is varied to change the characteristic. When the lighting quantity at the 5th time is selected to be 1/4 of the lighting quantity of the 1st to 4th lighting, the generated charge by the 1st-4th strobo lighting is as shown in figure A and the generated charge by the 5th strobo lighting is as shown in figure B. Thus, when the charges for the 5 lightings are added, the characteristic shown in figure C is obtained. That is, a nu characteristic appears depending on the difference from the characteristics A, B. Thus, no saturation takes place even in an object with a high reflectance.

Filed: 1990-10-17
Abstract: PURPOSE:To obtain an insulated-gate bipolar transistor whose turn-off loss is small by a method wherein, regarding a fourth region, a part which is distant from the contact face with a drain electrode in a first region is made deeper than a part which is close to it. CONSTITUTION:Carriers which have been supplied from a channel flow in a first region along the junction between a fourth region of a second conductivity type and a first region; a potential drop is caused; minority carriers are injected into the first region from the fourth region. Regarding the fourth region, a region layer 81 on the side distant form a contact face layer 8 with a drain electrode 9 in the first region is made deep.
