Publication number: 20220394176Abstract: An imaging apparatus includes: an image sensor that captures a subject image formed to generate image data; a recorder that records first image data showing images sequentially captured by the image sensor at a shooting period; and a controller operates the image sensor with a frame period shorter than half period of the shooting period, to generate one or plural frames of second image data by capturing in another frame period than the frame period for capturing the first image data within the shooting period. The second image data shows an image used for control in the imaging apparatus, captured with a setting different from a setting for the first image data. The control is performed based on a plurality of frames of image data including the one or plural frames of second image data, the plurality of frames being obtained by multiple times of capturing in the shooting period.Type: ApplicationFiled: June 2, 2022Publication date: December 8, 2022Inventors: Motonori OGURA, Tomohiro OOGAMI, Kohei FUKUGAWA

Patent number: 10277801Abstract: The image capture device includes an optical system including a focus lens, a CCD that captures a subject image input via the optical system and generates an image signal, an image processor that generates image data by performing predetermined processing on the image signal generated by the CCD, and a controller. The controller performs a scan operation for detecting a focus position for each of a plurality of partial regions of image data while moving the focus lens and records a moving image by moving the focus lens while switching a moving speed of the focus lens based on information on the focus position obtained for each of the plurality of partial regions as a result of the scan operation.

Patent number: 10148844Abstract: An imaging apparatus includes an optical system, an imaging unit that captures a subject image which is input via the optical system and generates an image signal, an image processor that performs predetermined processing on the image signal generated by the imaging unit and generates image data, a display unit that displays an image represented by the image data, and a control unit that controls the image processor and the display unit. The control unit records moving image data and generates, from all or a part of a plurality of frame images composing recorded moving image data, a still image based on user's specifying of an image or an area of the image. The display unit displays one frame image among the plurality of frame images composing the recorded moving image data, as a setting image for the user to specify an image or an area of the image, and adds highlighting to an in-focus portion in the setting image.Type: GrantFiled: November 3, 2016Date of Patent: December 4, 2018Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Mitsuyoshi Okamoto, Tomohiro Oogami, Kohei Fukugawa, Koji Takayama

Patent number: 8339473Abstract: A video camera includes an image sensor. The image sensor repeatedly outputs an object scene image captured on an imaging surface. A CPU detects a luminance component of the object scene image outputted from the image sensor, i.e., an AE/AWB evaluation value, and also detects a high-frequency component of the object scene image outputted from the image sensor, i.e., an AF evaluation value. Moreover, the CPU executes a flicker determining process for determining whether or not a flicker is occurred based on the luminance component of the object scene image. However, prior to the flicker determining process, whether or not there is a dynamic object in the object scene is determined based on the high-frequency component of the object scene image. The flicker determining process is prohibited when there is the dynamic object while it is permitted when there is no dynamic object.Type: GrantFiled: July 13, 2009Date of Patent: December 25, 2012Assignee: SANYO Electric Co., Ltd.Inventors: Kohei Fukugawa, Kazuhiro Tsujino

The image sensor repeatedly outputs an object scene image produced on an imaging surface having a plurality of pixels lined up in a vertical direction. A driver repeatedly executes an exposing operation for exposing the imaging surface for each pixel lined up in a vertical direction. A CPU repeatedly detects a plurality of luminance values respectively corresponding to a plurality of flicker evaluation areas allocated to the imaging surface in a manner to be located at positions different from one another in a vertical direction, based on the object scene image outputted from the image sensor. Moreover, the CPU determines the presence or absence of a flicker based on the plurality of luminance values thus detected.Type: GrantFiled: November 4, 2009Date of Patent: August 14, 2012Assignee: SANYO Electric Co., Ltd.Inventors: Takeshi Fujiwara, Kazuhiro Tsujino, Kohei Fukugawa

Patent number: 8174610Abstract: A camera includes an image sensor, and a plurality of metering areas are assigned to an object scene captured by the image sensor. A CPU evaluates a luminance of the object scene for each metering area, and binarizes each of the plurality of obtained luminance evaluated values. Furthermore, on the basis of the plurality of binarized luminance evaluated values, a width of a high luminance area included in the object scene is calculated while a width of an adjacent area adjacent to the high luminance area out of a low luminance area included in the object scene is calculated. Then, each of the plurality of luminance evaluated values is corrected on the basis of a ratio between the width of the calculated adjacent area and the width of the calculated high luminance area. An exposure amount to the image sensor is adjusted on the basis of the luminance evaluated values thus corrected.Type: GrantFiled: June 12, 2008Date of Patent: May 8, 2012Assignee: SANYO Electric Co., Ltd.Inventors: Kohei Fukugawa, Kazuhiro Tsujino

Patent number: 8077252Abstract: An electronic camera includes an image sensor having an imaging surface for capturing an object scene through a focus lens. When the object scene captured by the imaging surface includes a face portion of a human, a CPU designates, as a focal-point search area a first imaging area for covering an outline of the face portion. The CPU also designates, as a frequency-component detection area, a second imaging area that is smaller than the first imaging area and is for capturing an inner side of the outline of the face portion. Subsequently, the CPU obtains a high-frequency AF evaluation value and a mid-frequency AF evaluation value detected corresponding to the frequency-component detection area, and designates, as a lens moving range, a range different depending upon a relative ratio between the high-frequency AF evaluation value and the mid-frequency AF evaluation value.Type: GrantFiled: August 25, 2008Date of Patent: December 13, 2011Assignee: SANYO Electric Co., Ltd.Inventors: Kohei Fukugawa, Kazuhiro Tsujino
