Title:
ACTION CONTROL DEVICE AND ACTION CONTROL METHOD, IMAGING DEVICE, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2013/058166
Kind Code:
A1
Abstract:
This invention relates to an action control device and action control method, an imaging device, and a program, that can reduce focus lag. When a half-press operation is performed on an operation unit (17), a transmittance specification unit (28) browses a table (26) of transmittance-to-time, listed by temperature, and specifies the transmittance for a liquid crystal ND filter (44) at that timing, using the time passed since the timing that the voltage applied to the liquid crystal ND filter (44) was changed and the temperature measured by a thermistor (45). An ND filter control unit (24) reads the voltage corresponding to the transmittance at the timing that the half-press operation occurred, from a transmittance-to-voltage table (25), and applies same to the liquid crystal ND filter (44), thereby fixing the transmittance at the timing that the half-press operation occurred. A gain control unit (22) and a shutter control unit (23) adjust brightness that cannot be adjusted using the liquid crystal ND filter (44), by changing the gain and the shutter speed, using the difference between the transmittance at the timing of the half-press operation and the target transmittance. This technology can be applied to an imaging device.
