Abstract
Abstract The image sensing apparatus of the invention can easily and promptly search those areas of the main tracks of a floppy disk which store no data, or search or edit (e.g. copy) stored data, with the use of control data of a queue track and without an overhead. Further, it can automatically detect whether a recording medium is formatted upon insertion thereof, and then format it in a suitable manner if it has no formats.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
196 words
An electronic still camera for recording an image signal, supplied from an image sensing element attached to a main body of the electronic still camera, in a recording medium, comprising: converting means for converting the image signal into a digital signal having a predetermined format; determination means for determining, upon insertion of the recording medium in the electronic still camera, whether the recording medium was initialized in a predetermined format; control means for reading a disk formatting data signal including disk formatting data from said recording medium, said control means including means for verifying whether the disk formatting data signal has a specific initialized state; and recording means, including reformatting means for reformatting data in the recording medium in a given manner, if the determination means determines that the recording medium does not have the predetermined format; said recording means recording in the recording medium the digital signal having the predetermined format, if the determination means determines that the recording medium has the predetermined format; and said recording means recording the data reformatted in the given manner in the recording medium, if the determination means determines that the recording medium does not have the predetermined format.
Claim 2
Dependent Claim
196 words
An electronic still camera for recording an image signal, supplied from an image sensing element attached to a main body of the electronic still camera, in a recording medium, comprising: converting means for converting the image signal into a digital signal having a predetermined format; determination means for determining, upon insertion of the recording medium in the electronic still camera, whether the recording medium was initialized in a predetermined format; control means for reading a disk formatting data signal including disk formatting data from said recording medium, said control means including means for verifying whether the disk formatting data signal has a specific initialized state; and recording means, including reformatting means for reformatting data in the recording medium in a given manner, if the determination means determines that the recording medium does not have the predetermined format; said recording means recording in the recording medium the digital signal having the predetermined format, if the determination means determines that the recording medium has the predetermined format; and said recording means recording the data reformatted in the given manner in the recording medium, if the determination means determines that the recording medium does not have the predetermined format.
Claim 3
Dependent Claim
57 words
The electronic still camera according to claim 1, wherein: the recording means includes means for recording a plurality of formats, including the predetermined format; and the reformatting means does not reformat the data in the recording medium, if the format of the recording medium corresponds with one of the plurality of recorded formats, including the predetermined format.
Claim 4
Dependent Claim
87 words
The electronic still camera according to claim 1, further comprising: display means for displaying a format state of the recording medium if the determination means determines that the recording medium does not have the predetermined format; and ascertaining means for ascertaining whether the recording medium should be formatted; and wherein the reformatting means reformats the recording medium, if the ascertaining means ascertains that the recording medium should be re-formatted, and ejects the recording medium if the ascertaining means ascertains that the recording medium should not be re-formatted.
Claim 5
Dependent Claim
26 words
An electronic still camera according to claim 1, wherein the disk formatting data comprises: a header area; a directory area; and a Record Allocation Table area.
Claim 6
Dependent Claim
40 words
An electronic still camera according to claim 4, wherein: the Record Allocation Table area includes a plurality of sectors, said plurality of sectors representing all of a plurality of sectors of a plurality of main tracks in said recording medium.
Claim 7
Dependent Claim
75 words
An electronic still camera according to claim 4, wherein the directory area of the disk formatting data includes control data for indicating recording characteristics, including at least one of: unused record areas; erased record areas; record areas in which data cannot be written; record areas from which data cannot be erased; record areas from which data cannot be read out; record areas having preserved bits; and record areas for indicating a content of a record.
Claim 8
Dependent Claim
98 words
An electronic still camera according to claim 6, wherein the content of a record comprises data relating to at least one of: the image; a voice; a record name; a record extended name; a time at which the record is at least one of formed and finally edited; a data on which the record is at least one of formed and finally edited; a leading portion of a sector number that comprises a predetermined number of columns; a record size; a comment by a composer of the record; an explanation of an usual record; and an abnormal sector.
Claim 9
Dependent Claim
53 words
An electronic still camera according to claim 4, wherein the header area comprises data relating to at least one of: a format number; a disk name; a disk number; a number of used sectors; a number of unusable sectors; a number of remaining sectors; and a name of a composer of the record.
Claim 10
Dependent Claim
74 words
The electronic still camera according to claim 1, further comprising: second control means including means for determining a number of remaining sectors of the recording medium; said second control means including: means for enabling a disk full state to be displayed on a display means when there is no remaining sector in the recording medium; and means for enabling execution of an error-solving operation including a disk ejection operation and a disk formatting operation.
