Abstract:
To provide an interchangeable lens, a camera body, a camera system, and a method for controlling the same, with which a highly efficient and stable image blur correction effect can be obtained. A camera system (1) has a camera body (10) and an interchangeable lens (20) which is attachable to and detachable from the camera body (10). The camera body (10) has an imaging unit (120) for imaging a subject through the interchangeable lens (20), and a sequence microcomputer (100) capable of sending and receiving information to and from a lens microcomputer (200) and for controlling the imaging operation of an imaging unit (120). The interchangeable lens (20) includes a shake detection unit (201) for detecting shake in the camera system (1), an image blur correction device (210) for adjusting the optical path from a subject to the camera body (10) and thereby correcting the blurring of an image caused by shaking of the camera system (1), and the lens microcomputer (200) capable of sending and receiving information to and from the sequence microcomputer (100), and for controlling the drive of the image blur correction device (210) according to the amount of shake detected by the shake detection unit (201). The imaging optical system of the interchangeable lens (20) includes an aperture unit (206) which can adjust the imaging condition. The lens microcomputer (200) actuates the shake correction device (210) once a first set time has elapsed since the receipt of an adjustment command from the sequence microcomputer (100).
Abstract:
An inter-line CCD (IT-CCD) capable of reading signals in two read modes, a field read mode and a frame read mode, is used to control, by a system control means, a CCD exposure and a signal read mode, a short-time exposure signal (Short signal) acquires an image by a field read and a long-time exposure signal (Long signal) acquires an image by a frame read, and these two images are synthesized by a signal synthesizing means to expand a dynamic range.
Abstract:
When a shutter button of a digital camera is pressed, a picture signal fetched from a CCD is converted to a digital signal and compressed and written into a nonvolatile memory means like a flash memory card as a picture file which can be identified uniquely. A user can produce a control file for controlling print processing, display processing, transmission processing and the like for the picture file by selecting a particular picture file using an operation key. If multi-screen print is carried out on a printer unit, a vertical direction of each picture is unified. Further, upon reprint operation for multiple order persons, sorting work after the print is facilitated by providing with an identification means for identifying each order person.
Abstract:
At least one of a recorded image signal data, recorded audio signal data, and recorded image signal multiplex data, and reproduction information data describing the information about reproduction of at least one of the recorded image signal data, the recorded audio signal data, and the recorded image signal multiplex data or an arbitrary combination thereof, are stored. In this reproduction information data, the user can describe and edit by freely and easily combining the image data, audio data, and image/audio multiplex data. The CPU reads out image data and audio data from the storage means according to the reproduction information data, and decodes them, and converts the data format if necessary, and reproduces the image and audio in synchronism by using synchronization control means.

Abstract:
A video camera system has a recording portion and a reproducing portion. The recording portion includes an imaging device for imaging a subject and for generating a video signal, a parameter generator for generating parameters for imaging the subject, a parameter collector for collecting the parameters, a multiplexer for multiplexing the video signal with the parameters and for generating a multiplexed signal, and a recorder for recording the multiplexed signal on a tape. The reproducing portion includes a reproducer for reproducing the multiplex signal from the tape, a separator for separating the multiplexed signal into the video signal and the parameters, a condition detector for detecting a moment when the parameters are set in a predetermined condition, and for producing a condition detected signal, a image reducer for reducing a size of the video signal and for generating a reduced video signal, and a memory for storing the reduced video signal in response to the condition detected signal. In the memory multiple images obtained from different frames are stored for displaying the multiple image.
