ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a digital still video camera as well as to an image data output system for a digital still video camera, and more particularly to a digital still video camera as well as to an image data output system for a digital still video camera for outputting image data for the digital still video camera having a function for data transaction to recording paper through an image forming apparatus.
The present invention also relates to a digital still video camera in which an image and voice in combination can be recorded, and more particularly to a digital still video camera in which the operability, workability, and convenience are improved by making use of a function for inputting voices more effectively.
The present invention also relates to a frame for data relay for a digital still video camera as well as to a data transfer system for a digital still video camera, and more particularly to a frame for data relay for a digital still video camera as well as to a data transfer system for a digital still video camera in which the convenience thereof is improved when data is transferred between the digital still video camera and external device.
The present invention also relates to a digital still video camera for photographing an image and recording the image in a recording medium such as a memory card or the like, and more particularly to a digital still video camera always recording the photographed image in a recording medium without reducing a quantity of information for a main object for a photo.
The present invention also relates to a digital still video camera for recording at least photographed image in a recording medium, and more particularly to a digital still video camera for reporting a residual memory space of the recording medium with voices.
The present invention also relates to a digital still video camera for photographing an image and recording the image in a recording medium such as a memory card or the like, and more particularly to a digital still video camera in which a mask for identifying a photographed image area according to video which a user wants to record is selected, a form of the photographed image to be stored in the storage medium can freely be changed, and a number of pieces of video that can be stored in the storage medium is made to a maximum without degrading the quality of the recorded image, whereby the storage medium can effectively be utilized.
BACKGROUND OF THE INVENTION
At first, conventionally it is required an image data output system for a digital still video camera as shown in
FIG. 59A
to
FIG. 59D
in a case where an image photographed by a digital still video camera is outputted to recording paper through an image forming apparatus such as a printer.
For instance, FIG.
59
A and
FIG. 59B
show configuration in which image data is transferred from the digital still video camera (DSVC) to a computer through an I/F (an interface), and the image data is transferred to a printer using a printing function of the computer to be outputted to recording paper.
FIG.
59
C and
FIG. 59D
also show configuration in which image data is recorded in a recording medium set in a drive incorporated in the digital still video camera (DSVC), the image data stored in the recording medium is read in by a data reading device connected to the computer, and the image data is transferred to the printer using the printing function of the computer to be outputted to recording paper. As a recording medium, there are a floppy disk, a hard disk, a magneto-optical disk, and a memory card (IC card) or the like each of which is an ordinary one as computer peripheral equipment, and the memory card is generally used for the digital still video camera because read/write of the information can be executed at a high speed therein.
It should be noted that, in FIG.
59
B and
FIG. 59D
, a controller is provided between the computer and the printer, so that drawing at a higher speed and color correction with a mode advanced function can be realized by using the controller.
Secondarily, in recent years the digital still video cameras have come to incorporate multiple and versatile functions, and there have been developed various types of recording mode including, in addition to a still picture mode for recording a photographed image as a still picture, a successively photographing mode for successively recording still pictures, a voice mode for recording voices, a still picture+voice mode for simultaneously recording a still picture and voices, a moving picture mode for recording moving pictures like that in a video camera, a moving picture+voice mode for simultaneously recording moving pictures and voices, and a character mode for clearly recording characters or the like, or some other modes.
As a step for making a video still video camera more versatile, there is provided an operation mode such as a communicating function for fetching image data as well as voice data each photographed by the digital still video camera into external device such as a computer or the like.
Conventionally, in this type of digital still video camera in which image data and voice data in combination can be recorded, the inputted voice data is recorded using a voice compression technology. Also a listening method is used for regeneration, identification, and edit of the recorded voice data like in a case of a personal computer or a tape recorder.
Thirdly, as a system of transferring data between devices based on the conventional technology, a wire communication system for connecting devices to each other with a cable has generally been employed. However, radio communication making use of infrared rays is going to be standardized in order to respond to such users' request that they want to do data transfer without preparing a cable or the like.
There is the IrDA (Infrared Data Association) as a group for promoting this standardization. In the radio communication between devices according to this radio communication system, as shown in
FIG. 60A
, a face on which the transferring/receiving section
6001
a
of a device
6001
is provided at a position opposite to a face on which the transferring/receiving section
6002
a
of a device
6002
is provided, and data is transferred between the transferring/receiving sections
6001
a
and
6002
a.
In order to give flexibility to a positional relation between the devices, as shown in
FIG. 60B
, there is also provided a product in which the transferring/receiving section
6001
a
is separated from the device
6001
by using a serial port of the device
6001
such as a computer or the like.
On the other hand, a recording capability of the digital still video camera has remarkably progressed, so that it is now possible to execute various types of recording for recording not only still pictures but also moving pictures, and voices, or a mixture of moving pictures+voices or the like. An IC card enabling a high-speed read/write of data is mainly used for recording. To fetch this recorded data into equipment such as a personal computer or the like, a dedicated radio communication function or an IC card reader is required.
For this reason, if a radio communication function based on the IrDA standard is incorporated in the digital still video camera, communications between devices each having the radio communication function based on the IrDA standard can be made easier, which makes it possible to improve the convenience of use of a digital still video camera.
Fourthly, as a digital still video camera based on the conventional technology, there is the one disclosed, for instance, in Japanese Patent Laid-Open Publication No. HEI 4-332281 under the title of “Electronic camera and image signal compressing device”. This camera comprises a compressing means for subjecting an image signal obtained by an image pickup device to compression processing and an object distance detecting means for detecting a distance between a object and the camera, and adjusts a compression rate according to an output
