Patent number: 9877004Abstract: When a color-filter-array of a color-imaging-element is a Bayer-array, outputs of pixels prior to color-mixture correction are acquired from the color imaging element when red light is incident onto the color-imaging-element through a photography optical system, the outputs of the green pixels adjacent to the red pixels, among the acquired outputs of each pixel, are regarded as components of color mixture caused by the red pixels, and ratios of color mixture are calculated. In a central portion of an imaging surface of the color-imaging-element, ratios of color mixture, which do not depend on directions of the color mixture caused by the red pixels, are calculated. In end portions of the imaging surface of the color-imaging-element, separate ratios of color mixture according to the directions of the color mixture caused by the red pixels are respectively calculated. The calculated ratios of color mixture are subjected to interpolation calculation.Type: GrantFiled: November 12, 2015Date of Patent: January 23, 2018Assignee: FUJIFILM CorporationInventors: Arito Sawadaishi, Hayato Yamashita

Patent number: 8065908Abstract: Provided is an atomic force microscope capable of increasing the phase detection speed of a cantilever vibration. The cantilever (5) is excited and the cantilever (5) and a sample are relatively scanned. Displacement of the cantilever (5) is detected by a sensor. An oscillator (27) generates an excitation signal of the cantilever (5) and generates a reference wave signal having a frequency based on the excitation signal and a fixed phase. According to vibration of the cantilever (5), a trigger pulse generation circuit (41) generates a trigger pulse signal having a pulse position changing in accordance with the vibration of the cantilever (5). According to the reference wave signal and the trigger pulse signal, a phase signal generation circuit (43) generates a signal corresponding to the level of the reference wave signal at the pulse position as a phase signal of vibration of the cantilever (5). As the reference wave signal, a saw tooth wave is used.Type: GrantFiled: December 12, 2006Date of Patent: November 29, 2011Assignee: National University Corporation Kanazawa UniversityInventors: Takayuki Uchihashi, Toshio Ando, Hayato Yamashita

Patent number: 7958565Abstract: A driving laser unit (11) irradiates a laser beam on a cantilever (5) to cause thermal expansion deformation. A driving-laser control unit (13) performs feedback control for the cantilever (5) by controlling intensity of the laser beam on the basis of displacement of the cantilever (5) detected by a sensor (9). A thermal-response compensating circuit (35) has a constitution equivalent to an inverse transfer function of a heat transfer function of the cantilever (5) and compensates for a delay in a thermal response of the cantilever (5) to the light irradiation. Moreover, the cantilever (5) may be excited by controlling the intensity of the laser beam. By controlling light intensity, a Q value of a lever resonance system is also controlled. It is possible to increase scanning speed of an atomic force microscope.Type: GrantFiled: May 26, 2006Date of Patent: June 7, 2011Assignee: National University Corporation Kanazawa UniversityInventors: Toshio Ando, Takayuki Uchihashi, Noriyuki Kodera, Hayato Yamashita
