Patent number: 6753920Abstract: An electronic camera for producing a composite image having a wide dynamic range and a high quality by composing first and second image signals obtained by picking-up an object successively two times with first and second stroboscopic flash exposures having a predetermined exposure amount ratio, including a CCD image sensing element, a stroboscopic flash device, and a flash light control circuit for controlling an excited emission of said stroboscopic flash device. At an end of the first exposure, the excited light emission from the stroboscopic flash device is temporarily stopped, but an excited condition of the stroboscopic flash device is kept. During this very short light emission interruption period, electrostatic charges stored in a light receiving section of the CCD image sensing element during the first exposure are transferred into a vertical transfer section. After that, the excited flash light is emitted again to perform the second exposure without recharging a trigger capacitance.Type: GrantFiled: August 27, 1999Date of Patent: June 22, 2004Assignee: Olympus Optical Co., Ltd.Inventors: Takumi Momose, Hidetoshi Fukuda, Hiroaki Koseki, Minoru Kakinuma, Osamu Inagaki

Patent number: 6088059Abstract: An electronic imaging apparatus capable of obtaining high image quality that serves for printed photographs, e.g. DTP and posters. The apparatus has an image-forming optical system (1), a solid-state image pickup device (3), a signal processing device (4), and a sensor driving circuit (5). The image-forming optical system (1) includes a diffraction lens for correcting chromatic aberrations. The signal processing device (4) includes an image processing device for removing flare components due to unwanted orders of diffracted light produced by a diffraction surface. The image processing device obtains a flare component by performing the convolution of the point image energy intensity distribution of each unwanted order of diffracted light with the energy intensity distribution of an image signal, and subtracts the flare component from the image signal to obtain a corrected image signal.Type: GrantFiled: December 26, 1996Date of Patent: July 11, 2000Assignee: Olympus Optical Co., Ltd.Inventors: Shinichi Mihara, Osamu Inagaki, Gakuji Kamishima, Atsuo Goto
