Patent number: 7280142Abstract: A solid-state imaging apparatus includes: a defective pixel detector (8) for extracting, from a signal output by a frame-reading solid-state image pickup element (2), pixel data for a target pixel for which a determination is to be made and pixel data for peripheral pixels thereof, and for employing pixel data for a pixel, selected from among the peripheral pixels, in the same filter as the target pixel, to determine whether the target pixel is a defective pixel; and a defective pixel correction circuit (9) for employing the pixel data for the peripheral pixels to correct pixel data for the defective pixel. With this configuration, the output signal of the defective pixel can be corrected without spreading the effect produced by the defective pixel to the peripheral pixels, and a natural image can be displayed.Type: GrantFiled: September 27, 2002Date of Patent: October 9, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Keiji Toyoda, Yuichiro Sugioka, Masaki Kariya

Patent number: 6882363Abstract: An automatic gain controlling circuit controls a gain of a video signal from an imager having an electronic shutter function according to a gain control signal. An average detecting circuit detects an average level of a luminance signal of the video signal. An automatic exposure controlling circuit generates the gain control signal according to the luminance average level in response to a mode signal indicative of the cycles per second of the ac line and generates a timing signal corresponding to the ac line and a shutter speed control signal together with electronic shutter control signal generation circuit at a unit of the voltage variation cycle of the ac line according to the luminance average level such that a shutter interval of the imager is changed stepwise and each of the shutter intervals is an integer times the voltage variation cycle of the ac line.Type: GrantFiled: January 27, 2000Date of Patent: April 19, 2005Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Kazuo Oda, Masaki Kariya
