Patent number: 9544502Abstract: A dark exposure control device comprises a dark exposure performing processor, an aperture-stop, and an aperture-stop driving processor. The dark exposure performing processor detects an image signal generated by an imaging device while the shutter is closed. The aperture-stop adjusts the amount of light incident on the imaging device. The aperture-stop driving processor adjusts the opening degree of the aperture-stop to smaller than the opening degree set for a main exposure while the dark exposure performing processor is operated.Type: GrantFiled: February 7, 2013Date of Patent: January 10, 2017Assignee: PENTAX RICOH IMAGING COMPANY, LTD.Inventors: Naoto Asakura, Yoshitaka Kimura, Kosei Kosako

Patent number: 8848071Abstract: An imaging apparatus capable of capturing a moving image with an imaging device is equipped with a first image-processing device that uses hardware to process images captured by the imaging device and a second image-processing device that processes captured images with software. The imaging apparatus includes an image-processing switching device that selectively operates one of either the first image-processing device or the second image-processing device. The imaging apparatus includes a light-detection device that detects the amount of light received by the imaging device and a sensitivity adjustment device that increases the sensitivity of the imaging device as the amount of light decreases. The image-processing switching device operates the first image-processing device when the sensitivity is lower than a predetermined value and operates the second image-processing device when the sensitivity is higher than the predetermined value.Type: GrantFiled: September 5, 2012Date of Patent: September 30, 2014Assignee: Pentax Ricoh Imaging Company, Ltd.Inventor: Naoto Asakura
