Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic camera that records captured image information on a magnetic disk.

2. Description of the Related Art Conventionally, electronic cameras that record captured image information on magnetic disks have used /J1 type disks in consideration of their portability. Therefore, directory tracks such as disks used as external storage devices for computers are generally deleted. For this reason,
When monitoring the image information recorded on a disc, it is necessary to call up sequential single image information, and it is impossible to view any image at random, and information related to the image (e.g. title, date, location, etc.) is required. etc.) could not be monitored at the same time.

On the other hand, it is conceivable to limit the idea of miniaturization and make the disk larger to provide a directory track, but when this is used in an electronic camera, problems have arisen in terms of the lifespan of the disk.

That is, it is obvious that the service life of the disk is generally the longest, and the service life of the disk decreases. Further, due to the nature of electronic cameras, they are expected to be used under various environments, which further worsens the durability conditions. Furthermore, the unique advantage of using a disk, which allows for re-editing, also contributes to the reduction in the service life mentioned above.

Therefore, this point is also a major reason why it is not possible to provide a directory track on the disk of an electronic camera.

The present invention has been made based on the above-mentioned problems,
The purpose of this is to make it possible to store the necessary information in the directory without providing a directory track on the magnetic recording medium by simply installing an extremely simple electronic circuit inside the disk pack. The purpose of the present invention is to provide an electronic camera with improved performance and miniaturization.

In order to achieve the above object, the present invention is used as an information storage means for a disk left storage, and at the same time, is used as a means for transferring data between the disks and image information in the disk pack. It is characterized in that directory information from the CPU is written into the disk or nonvolatile solid-state memory within the disk at the same time as recording.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

FIG. 1 is a perspective view showing a main body 1, a disk pack 2, and a home unit 3 of an electronic camera according to this embodiment.

In FIG. 1, a main body 1 is provided with a lens 4, a lens 4, an inverter 5 on its front surface, and a shutter 6, a power switch 7, a strobe contact 8, etc. on its top surface.

Further, inside the main body 1 with the back cover 23 opened, a disk drive shaft 24, a magnetic head 25, a magnetic head drive shaft 26, a power terminal 27, and an LED/photodiode array 28 are arranged.

Here, the disk and motherboard 2 are now inside the main body 1.
When inserted, the discs are mounted at opposing positions of the four discs 2. Also, the magnetic head 25' is connected to the disk/(') from the magnetic head insertion hole 13 of the disk 2 to the disk I.
OK to contact. The movement of the magnetic head 25 is performed by word of mouth of a magnetic head drive shaft 26 which is a ball screw.

FIG. 4 is a professional diagram showing the electrical configuration of the electronic camera in this embodiment. Note that the same parts as in FIGS. 1 to 3 are denoted by the same reference numerals, and detailed explanations will be omitted.

In FIG. 4, an optical image of the subject 9 formed on an image sensor 30 such as a 9 CCD through a lens 29 is converted into a photoelectric conversion signal by the image sensor 30 and sent to an image processing circuit 31. The image processing circuit 31 converts the photoelectric conversion signal into recordable image information and sends it to the data selector 32. This image information is selected by the digital camera controller 33 and becomes a magnetized output by the magnetic head 25.

This magnetic head 25 is connected to the disk 1 in the disk pack 2.
The image information is recorded in 0.

On the other hand, various information such as the title, date, shooting location, etc. is inputted into the image 5, and these various types of information are carried out by the CP command and the data regarding the recording position such as the track number and the 1-odd diode array 18.28.

Further, information such as the image number necessary for searching the image information in the track is converted into serial data and sent to the data selector 32 via the serial I1036'f- from the CPU 35.

Disk controller 33 receives instructions from CPU 35
- writes this serial data to the beginning of the image information recording section on the disk. In this way, various types of information related to the image information in the solid-state memory 15 have a perfect correspondence with the image information on the disk 10.
IJ becomes possible.

The drive of the disk 10, the movement of the magnetic head 25, etc. are performed by the disk controller 33 according to operation commands from the CPU J 5 and according to a predetermined program in the ROM 37. A disk drive command from the disk controller 33 is sent to a servo circuit 38, and a motor 39 is driven at a constant speed by a rotation command signal from the servo circuit 38. Further, the magnetic head position control command (d step motor drive circuit 4
0, and the step motor 41 is activated by the f pulse signal from the step motor drive circuit 40. - Magnetism by Renezo - The Rad drive shaft 26 is rotated to determine the magnetic head position.

Therefore, for example, if data is input into the solid-state memory 15 regarding an image or a track that can be erased when a new image is taken, the CPU 35 reads this data and protects it from the disk controller 33 when the image is transported. Give information about the tracks you need. The disk controller 33 receives this information and drives the step motor 41 for the track to be skipped.

As described above, an image is recorded by inserting the disk 2 which stores information regarding the directory into the solid-state memory 15 into the insertion hole 42 of the home unit 3 shown in FIG. Information is monitored on display 43.

This home unit 3 is used not only for monitoring but also for image editing and recording. At this time, it is sufficient to operate the keyboard 44 to retrieve any image information from the disc 10. The edited image information is then stored in a large capacity memory in the home unit 3 and can be reused on the disk or drive 21d.

Furthermore, if necessary, by providing a color copy function, it is possible to output a single-page hard copy 45.

In the electronic camera according to this embodiment having the above configuration, a solid-state memory 15, an LED/photodiode array 18, etc. are provided in a part of the disk pack 2, directory information @ is stored in the solid-state memory 15, and the LED/photodiode array 18 is stored in the solid-state memory 15. The array 18 performs data exchange between the CPU 35 in the main body 1 and the directory.

Therefore, it will not affect the service life of the disk 10 in any way, and it will not have any effect on the service life of the disk 10.
It is possible to add 17 functions.

As described above, according to the present invention, directory-enabled imaging can be performed by simply adding an extremely simple circuit to the disk motherboard, and since the method of providing the directory track on the disk is different, durability is improved.
