Abstract: There is provided an imaging apparatus including a first focus detection unit that has a plurality of first focus detection areas in a photographed screen, and detects a first defocusing amount in the first focus detection areas, a second focus detection unit that has a plurality of second focus detection areas in a photographed screen, and detects a second defocusing amount in the second focus detection areas, a defocusing amount selection unit that selects which of the first defocusing amount detected by the first focus detection unit and the second defocusing amount detected by the second focus detection unit is used, and a focus control unit that performs focus control by moving a focus lens on the basis of the defocusing amount selected by the defocusing amount selection unit.

Abstract: An imaging apparatus which includes a range-finding region arrangement unit which arranges range-finding regions of which region sizes are different by hierarchizing thereof, a range-finding region selection unit which selects the range-finding region in a predetermined order from the arranged range-finding regions, and a control unit which performs a focusing operation by generating an evaluation value which denotes degree of focusing with respect to the range-finding regions which are selected in the range-finding region selection unit, and controlling a position of a focus lens based on the evaluation value.

Abstract: The present technology is provided to allow a user to easily recognize a subject to be given priority. A focusing target selection unit selects, from among a plurality of first focus detection areas in which a focus is detected by a first focus detection unit, an area to be focused as a focusing target area on the basis of a detected result of the focus in the first focus detection areas. A display area selection unit selects, from among a plurality of second focus detection areas in which a focus is detected by a second focus detection unit, an area to be displayed as a display area along with the focusing target area on the basis of a detected result of the focus in the plurality of second focus detection areas. A display control unit causes a display unit to display the display area.

Abstract: An imaging apparatus includes: continuous imaging mode setting means for setting a continuous imaging mode in which a plurality of captured images including first and second captured images are continuously acquired; and diaphragm control means for controlling a diaphragm in an imaging optical system, wherein in the continuous imaging mode, the diaphragm control means does not drive the diaphragm during a first period from the time of exposure for the first captured image to the time of exposure for the second captured image but maintains the state of the diaphragm at the time of exposure for the first captured image until the time of exposure for the second captured image.

Abstract: There is provided with an encoded digital audio reproducing apparatus including: a reading control portion which reads an encoded audio file having a data part including audio data as a sequence of frames and a size part including size information on each of the frames; a table generating portion which generates a table holding positional information on frames at intervals of a predetermined number of frames in the sequence of frames; a decoding portion which sequentially decodes the audio data from a leading frame to output the decoded audio data; a reproducing portion which reproduces the decoded audio data; and a reproduction start position calculating portion which, in the case where a reproduction request from an arbitrary frame in the audio data is inputted, decides from the table a frame satisfying a positional reference for the arbitrary frame as a reproduction start frame.

Abstract: A decoding reproduction apparatus has an input memory buffer to which audio data asynchronously transmitted is input, a decoding circuit which is configured to read out and decode encoded data stored in the input memory buffer, an output memory buffer which is configured to store an output from the decoding circuit, and an output control circuit which is configured to monitor an amount of use of the input memory buffer, to output the data stored in the output memory buffer by decimation the data when the amount of use becomes larger than a predetermined upper-limit threshold value, and to output the data stored in the output memory buffer by interpolating the data when the amount of use becomes smaller than a predetermined lower-limit threshold value. Occurrence of an overflow or an underflow in the buffer as a result of D/A conversion of the audio data synchronously transmitted is prevented.
