20140368677 | ACTUATOR DRIVING DEVICE, CONTROL METHOD FOR SAME, AND IMAGING APPARATUS - An actuator driving device drives an actuator connected to an output terminal. The control unit of the actuator driving device includes a PWM delay time setting unit, a first duty ratio setting unit, and a second duty ratio setting unit. The PWM delay time setting unit sets a delay time of pulse width modulation control for a driving voltage to be applied to the output terminal and outputs setting information to the first and second duty ratio setting units. The first duty ratio setting unit sets the first duty ratio for a first PWM output unit, and the second duty ratio setting unit sets the second duty ratio for a second PWM output unit. When positive and negative energization is performed, the control unit controls to reduce the amount of change in current in the current peak of a PWM waveform by providing a short-circuit period in response to the energization amount. | 12-18-2014 |

20130176455 | IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD - According to one embodiment, an image processing apparatus includes a calculation unit. The calculation unit calculates a reliability for each of pixel areas in such a manner that the reliability increases with increasing at least one of (1) a first evaluation value which increases with increasing planarity, in a color space, of a distribution of pixel values in each of the pixel areas, (2) a second evaluation value which increases with increasing wideness of pixel values in each of the pixel areas on an estimated plane approximating the distribution of the pixel values in each of the pixel areas in the color space, and (3) a third evaluation value which increases with decreasing distance between the estimated plane and an origin of the color space. | 07-11-2013 |
20140098263 | IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD - According to an embodiment, an image processing apparatus includes a scattered light acquisition unit, a control information acquisition unit and a control unit. The scattered light acquisition unit acquires an amount of scattered light included in each pixel of an input image. The control information acquisition unit acquires control information determining an amount of scattered light included in each pixel of an output image. The control unit generates the output image by controlling the amount of the scattered light included in each pixel of the input image based on the control information. | 04-10-2014 |
