Abstract
Abstract A film image reproduction signal output apparatus is provided which picks up an image on a developed film by a CCD, and produces an image reproduction signal by an image pickup circuit so that the image is displayed on a monitor. The present output apparatus detects whether the film contained in a cartridge loaded in the apparatus is a negative film or a positive film. If the negative film is detected, the image pickup circuit produces the image reproduction signal by reversing an image signal received from the CCD, for display on the monitor.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
103 words
A film image reproduction signal output apparatus comprising: an image pickup device that picks up an image on a film that has been developed; an image reproduction circuit that produces an image reproduction signal based on an image signal received from said image pickup device; a film type detector that determines whether said film is a negative film or a positive film; and a control circuit that controls said image reproduction circuit so as to produce said image reproduction signal by reversing said image signal from said image pickup device when said film type detector determines that said film is a negative film.
Claim 2
Dependent Claim
103 words
A film image reproduction signal output apparatus comprising: an image pickup device that picks up an image on a film that has been developed; an image reproduction circuit that produces an image reproduction signal based on an image signal received from said image pickup device; a film type detector that determines whether said film is a negative film or a positive film; and a control circuit that controls said image reproduction circuit so as to produce said image reproduction signal by reversing said image signal from said image pickup device when said film type detector determines that said film is a negative film.
Claim 3
Dependent Claim
44 words
A film image reproduction signal output apparatus according to claim 1, wherein said film type detector determines whether said film is a negative film or a positive film based on information recorded on one of said film and a film cartridge containing the film.
Claim 4
Dependent Claim
43 words
A film image reproduction signal output apparatus according to claim 1, wherein said control circuit recognizes that said film is a negative film when the film type detector is incapable of determining whether the film is a negative film or a positive film.
Claim 5
Dependent Claim
84 words
A film image reproduction signal output apparatus according to claim 1, further comprising: a film feeding device that drives said film so that said image pickup device can pick up an unexposed portion of said film; and a white balance circuit that performs a white balance control for said image signal of the film frame to be picked up based on said image signal of said unexposed portion of said film when said film type detector determines that said film is a negative film.
Claim 6
Dependent Claim
167 words
A film image reproduction signal output apparatus according to claim 1, further comprising: a white balance circuit that performs a white balance control for an image signal with a first white balance mode or a second white balance mode, in said first white balance mode, said white balance control being done based on the picked up image signal, and in said second white balance mode, said white balance control being done based on a fixed value previously set, and a white balance selection device that selects any one of said first and second white balance modes, wherein said white balance circuit, (1) performs a white balance control with the selected white balance mode, when said film type detector determines that said film is a negative film, and (2) performs a white balance control with said second white balance mode even if said first white balance mode is selected by said white balance selection device, when said film type detector determines that said film is a positive film.
Claim 7
Dependent Claim
153 words
A film image reproduction signal output apparatus, comprising: an apparatus body that holds a film that has been developed; a camera unit that picks up an image on said film, said camera unit being detachable from said apparatus body; an image reproduction circuit that produces an image reproduction signal based on an image signal received from said camera unit; a camera unit state detector that determines whether said camera unit is attached to or detached from said apparatus body; a film type detector that determines whether said film is a negative film or a positive film; and a control circuit that controls said image reproduction circuit so as to produce said image reproduction signal by reversing said image signal from said camera unit if said camera unit state detector determines that said camera unit is attached to said apparatus body, and said film type detector determines that said film is a negative film.
Claim 8
Dependent Claim
153 words
A film image reproduction signal output apparatus, comprising: an apparatus body that holds a film that has been developed; a camera unit that picks up an image on said film, said camera unit being detachable from said apparatus body; an image reproduction circuit that produces an image reproduction signal based on an image signal received from said camera unit; a camera unit state detector that determines whether said camera unit is attached to or detached from said apparatus body; a film type detector that determines whether said film is a negative film or a positive film; and a control circuit that controls said image reproduction circuit so as to produce said image reproduction signal by reversing said image signal from said camera unit if said camera unit state detector determines that said camera unit is attached to said apparatus body, and said film type detector determines that said film is a negative film.
Claim 9
Dependent Claim
44 words
A film image reproduction signal output apparatus according to claim 6, wherein said film type detector determines whether said film is a negative film or a positive film based on information recorded on one of said film and a film cartridge containing the film.
Claim 10
Dependent Claim
44 words
A film image reproduction signal output apparatus according to claim 6, wherein said film type detector recognizes that said film is a negative film when the film type detector is incapable of determining whether the film is a negative film or a positive film.
Claim 11
Dependent Claim
84 words
A film image reproduction signal output apparatus according to claim 6, further comprising: a film feeding device that drives said film so that said image pickup device can pick up an unexposed portion of said film; and a white balance circuit that performs a white balance control for said image signal of the film frame to be picked up based on said image signal of said unexposed portion of said film when said film type detector determines that said film is a negative film.
Claim 12
Dependent Claim
167 words
A film image reproduction signal output apparatus according to claim 6, further comprising: a white balance circuit that performs a white balance control for an image signal with a first white balance mode or a second white balance mode, in said first white balance mode, said white balance control being done based on the picked up image signal, and in said second white balance mode, said white balance control being done based on a fixed value previously set, and a white balance selection device that selects any one of said first and second white balance modes, wherein said white balance circuit, (1) performs a white balance control with the selected white balance mode, when said film type detector determines that said film is a negative film, and (2) performs a white balance control with said second white balance mode even if said first white balance mode is selected by said white balance selection device, when said film type detector determines that said film is a positive film.
Claim 13
Dependent Claim
59 words
A film image reproduction signal output apparatus according to claim 10, wherein, when said camera unit state detector determines that said camera unit is detached from said apparatus body, said white balance circuit performs a white balance control with said first white balance mode even if said second white balance mode is selected by said white balance selection device.
