| 20100328515 | ELECTRONIC STILL CAMERA WITH CAPABILITY TO PERFORM OPTIMAL FOCUS DETECTION ACCORDING TO SELECTED MODE - An electronic still camera includes a finder optical system for viewing a subject image. An imaging section obtains the subject image. A display section displays the subject image based on image data associated with the subject image obtained by the imaging section. A mode selecting section selects either a first mode in which the electronic still camera performs imaging operation using the imaging section while a user views the subject image through the finder optical system or a second mode in which the electronic still camera performs imaging operation using the imaging section while the user views the subject image on the display section. A first focus detection circuit performs a first focus detecting operation when the first mode is selected by the mode selecting section. A second focus detection circuit performs a second focus detecting operation when the second mode is selected by the mode selecting section. | 12-30-2010 |
| 20100201852 | IMAGE PROCESSING APPARATUS - An image processing apparatus includes a photographing condition estimation unit for estimating a photographing condition of the input image based on photometric information and focal information. A Y/C separation unit separates the input image into a luminance signal and a color difference signal; a luminance correction unit extracts an edge from the luminance signal and corrects the luminance signal by a gradation conversion curve; a color difference correction unit corrects the color difference signal based on luminance signals obtained before and after the gradation correction and a theoretical limit characteristic of color reproduction; a skin color correction unit performs skin color correction depending on the photographing condition; and a Y/C synthesis unit synthesizes the luminance signal and the color difference signal obtained after the correction. Gradation correction is performed on the input image such that appropriate hue and saturation are achieved while emphasizing a main object. | 08-12-2010 |
| 20100118396 | CONFOCAL MICROSCOPE APPARATUS - A microscope apparatus includes a first optical system which illuminates a sample via an objective lens with light output from a light source and which detects fluorescence emitted from the sample via the objective lens, and a second optical scanning system which irradiates specific regions of the sample with a laser beam output from a laser light source, thereby causing a particular phenomenon. The first optical system may include a rotatable disk to obtain a confocal effect, and the light output from the light source scans the sample via the rotatable disk, and the fluorescence is detected via the rotatable disk. A depth position of a focal plane of the second optical scanning system is generally the same as a depth position of a focal plane of the first optical system. | 05-13-2010 |
| 20100110224 | ELECTRONIC CAMERA - Disclosed herein is an electronic camera for generating an image having a wide dynamic range by synthesizing two image pickup signals of different exposure amount generated by using an electronic shutter function and means for shutting off light, shading of image pickup signals resulting from difference in charge accumulating time among the pixels of image pickup device due to operation from opened state to closed state of the means for shutting off light being corrected by a shading correction means to form a synthesized image without an occurrence of false color due to shading. Also provided is an electronic camera generating two image pickup signals of different exposure amount by two shots of picture taking each using a flash emission in combination, at least one of an electronic shutter of image pickup device and means for shutting off light, as well as an emission of the flash emission means, being controlled to equalize between the two shots of picture taking ratio of exposure by normal light excluding light from the flash emission means and ratio of emission amount by the light from the flash emission means so that the two image pickup signals can be readily generated as having a predetermined exposure amount ratio in every part of a frame of picture even when a flash emission is used in combination. | 05-06-2010 |

| 20090086038 | IMAGING APPARATUS INCLUDING A COOLED IMAGING ELEMENT WHICH IS SHIFTED TO PERFORM HIGH-DEFINITION IMAGING - A highly thermal conductive member is filled in a gap between a base portion and a movable portion of a spring stage in an image shift type imaging apparatus. Heat from a heat generating surface of a cooling element is conducted from the movable portion to the base portion through the highly thermal conductive member, and it is further conducted to an inner lid and discharged to the outside of an imaging apparatus housing. | 04-02-2009 |
| 20090067695 | IMAGE PROCESSING SYSTEM WHICH CALCULATES AND DISPLAYS COLOR GRADE DATA AND DISPLAY IMAGE DATA - An image processing system is used for dentistry. Upon creating a false tooth of a patient ( | 03-12-2009 |
| 20090051803 | CAMERA HAVING A DUST-PROOFING MEMBER THAT IS VIBRATED TO REMOVE DUST, THE DUST-PROOFING MEMBER BEING PRESSED BY A SPRING PRESSING MEMBER TOWARD A SEALING PART THAT SEALS A SPACE BETWEEN THE DUST-PROOFING MEMBER AND AN IMAGE PICKUP-DEVICE - A camera includes a dust-proofing member which has a transparent portion through which a visible light component is transmitted. The transparent portion is opposed to the front of an image pick-up device at a predetermined interval. A vibration member is arranged at a peripheral portion of the dust-proofing member and vibrates the dust-proofing member. A sealing part seals a space between the image pick-up device and the dust-proofing member. And a spring pressing member presses the dust-proofing member at a periphery thereof toward the sealing part. | 02-26-2009 |
| 20090016602 | COLOR REPRODUCING DEVICE - A multi-spectral camera is provided which includes an image pickup optical system which forms an image of a subject. A wavelength selecting device receives light beams from the image pickup optical system and outputs a light beam having a selected wavelength. A wavelength switching device selectively switches the selected wavelength of the wavelength selecting device. An image pickup element receives the light beam output from the wavelength selecting device and outputs image data. A spectroscope receives the light beams from the image pickup optical system and outputs spectral data. And a subject characteristic calculating unit calculates a spectral data characteristic of the subject from the spectral data output from the spectroscope. | 01-15-2009 |
