Patent number: 7529383Abstract: An image input apparatus which reconfigures a single reconfigured image from a plurality of low-resolution, object reduced images formed in a specified region on the light detecting element by the micro-lens array, wherein a high-resolution, single reconfigured image can be obtained even if the distance between the subject and the micro-lens array is long (infinitely long, for example), and further a reconfigured image can be realized in colors. The image input apparatus is characterized in that the relative distance between a micro-lens (1a) and light detecting cells (3a) in a specified region, where object reduced images corresponding to the micro-lens (1a) are formed, is different in each micro-lenses (1a). In addition, the light detecting cells (3a) are divided into a plurality of regions, and color filters (primary color filter, or complementary color filter, for example) are disposed in each of the divided regions.Type: GrantFiled: October 24, 2003Date of Patent: May 5, 2009Assignee: Konica Minolta Holdings, Inc.Inventors: Shigehiro Miyatake, Jun Tanida, Kenji Yamada

Patent number: 6836291Abstract: A solid-state, two-dimensional image sensing device having a matrix of pixels each of which employs a photosensor that generates a photocurrent and a MOS circuit which outputs a signal proportional to the logarithm of the integral over time of the photocurrent. The sensor includes an integration control switching device so that all pixels in the array have equal integration time. The sensor integrates the signal for each pixel for a period of time and stores the integrated signal in a pixel signal storage location. To read out the stored signal each pixel includes an amplifier to increase the signal during read out. The sensor further accumulates signal in either a MOS transistor pn-junction or a secondary pixel storage location during a time that the integrated pixel signal is being read out so that image information can be collected continuously even while the integrated pixel signal for each pixel is being read.Type: GrantFiled: April 1, 1999Date of Patent: December 28, 2004Assignee: Minolta Co., Ltd.Inventors: Satoshi Nakamura, Kenji Takada, Yoshio Hagihara, Shigehiro Miyatake
