| 20090034960 | OPTICAL OBSERVATION APPARATUS AND IMAGE-PICKUP APPARATUS - The optical observation apparatus includes an optical element which reflects a first wavelength region light from an object to introduce the light to an eyepiece part, and a light source which emits a second wavelength region light. A wavelength-selective optical film which transmits the first wavelength region light and reflects the second wavelength region light is disposed inside the optical element. The optical observation apparatus superimposes an image formed by the second wavelength region light reflected by the wavelength-selective optical film on an object image formed by the first wavelength region light transmitted through the wavelength-selective optical film to cause an observer to observe the object image with the superimposed image through the eyepiece part. The optical observation apparatus can superimpose an optional image on the object image to enable the observer to observe these images without a deterioration of viewfinder performance. | 02-05-2009 |
| 20100003025 | IMAGING APPARATUS - An imaging apparatus includes an image sensor configured to capture an image of a subject, a finder optical system configured to enable a photographer to optically observe the subject, and an image display unit disposed in the finder optical system and configured to display an image of the subject captured by the image sensor and to enable the photographer to observe an electronic image of the subject when the photographer looks in the finder optical system. The image display unit is configured to display an image having been subjected to image processing performed on the electronic image considering a distortion caused by the finder optical system. | 01-07-2010 |
| 20100013947 | PHASE DIFFERENCE DETECTION DEVICE, IMAGING APPARATUS, PHASE DIFFERENCE DETECTION METHOD - The ratio between an image A and an image B is calculated as the comparison result of the images A and B obtained from a pair of optical images. The variance is then calculated in order to evaluate the statistical fluctuation of the ratio obtained for each pixel. The fluctuation due to the variance is evaluated for each phase difference while the phase between the image A and the image B is shifted. The phase difference detection is performed on the basis of the evaluation result of the fluctuation. | 01-21-2010 |
| 20100103305 | IMAGE CAPTURE APPARATUS WITH OPTICAL FINDER - A first display region for displaying an optical image of an object and a second display region for displaying information are provided for a finder device. The first display region and the second display region can be observed at the same time through an eyepiece window. On the second display region, an electric image that is photoelectrically converted by an image pickup element is displayed. That reduces failures to take a shutter chance and enables a state of the captured image and auxiliary information to be checked. | 04-29-2010 |
| 20110044677 | IMAGE CAPTURE APPARATUS AND METHOD - An image capture apparatus comprises: a moving unit configured to move a focus position of a photographing lens relative to an image sensor at a predetermined amplitude by changing a distance in an optical axis direction between the photographing lens and the image sensor; detection unit configured to detect a focus state of an image obtained from the image sensor; and defocus correction unit configured to perform defocus correction on the image obtained from the image sensor during motion performed by the moving unit, based on the focus state detected by the detection unit, so that the focus state of each image for display on the display device at least approaches the focus state for an in-focus image. | 02-24-2011 |
