Patent number: 5426731Abstract: A video data processing apparatus converts one of NTSC type and VGA type video signals to the other or overlays the two types of video signals and outputs them as either an NTSC type overlaid video signal or a VGA type overlaid video signal. The processing apparatus has two video memories for storing video signal data. One of the two video memories stores solely VGA type video data. The other video memory stores either VGA type video data or NTSC type video data depending upon the particular function being carried out by the processing apparatus. Video data may be read out from the other video memory using different scan rates so that an individually dedicated memory is not required for each type of video data in performing the above-mentioned conversions and overlays.Type: GrantFiled: July 19, 1994Date of Patent: June 20, 1995Assignee: Fuji Photo Film Co., Ltd.Inventors: Kazuyuki Masukane, Kenneth E.

Patent number: 5420635Abstract: A suitable image is obtained of a subject in which the difference in luminance between a bright area and a dark area is very large. The dark area is properly exposed and first image data is obtained. The bright area is properly exposed, and second image data is obtained. The first image data pertaining to the bright area is replaced with the second image data, thereby obtaining composite image data. This is accomplished using an array of photodiodes comprising two sets of photodiodes, one set of the photodiodes comprising filters, and the respective sets of photodiodes output signals to respectively different transfer paths for signal processing.Type: GrantFiled: August 28, 1992Date of Patent: May 30, 1995Assignee: Fuji Photo Film Co., Ltd.Inventors: Masahiro Konishi, Makoto Tsugita, Masafumi Inuiya, Kazuyuki Masukane

Patent number: 5396288Abstract: A suitable image signal is obtained even with regard to a subject exhibiting a very large difference in luminance between bright and dark areas. A video signal obtained from a CCD by imaging the subject is amplified by a first amplifier, converted into digital image data A by a first A/D converter and then stored in a first memory. The video signal from the CCD is also amplified by first and second amplifiers, converted into image data B by a second A/D converter and then stored in a second memory. The amplification factor of the first second amplifier is set such that a comparatively dark area of the image of the subject will assume a level having an appropriate brightness. A multiplexer selects data representing a comparatively bright area of the image of the subject from image data read out of the first memory as well as data representing a comparatively dark area of the image of the subject from image data read out of the second memory.Type: GrantFiled: July 19, 1993Date of Patent: March 7, 1995Assignee: Fuji Photo Film Co., Ltd.Inventors: Makoto Tsugita, Kazuyuki Masukane
