Image display apparatus

An image display apparatus for displaying an image recorded on a film, comprising:

• a) a spatial light modulation device which can maintain a recorded image in a non-energization state;
• b) an illumination device for illuminating said spatial light modulation device with light;
• d) a switching mechanism for switching between a first state in which said film is located between said spatial light modulation device and said illumination device and a second state in which said film is not located between said spatial light modulation device and said illumination device;
• and
• e) a control circuit for activating said spatial light modulation device and said illumination device in said first state when an image recorded on said film is to be recorded on said spatial light modulation device, and activating said illumination device in said second state when said spatial light modulation device on which the image is recorded is to be observed.

• and
• e) a control circuit for recording the image recorded on said film on said spatial light modulation device by activating said spatial light modulation device and said illumination device in said first state, and deleting the image recorded on said spatial light modulation device by activating said spatial light modulation device and said illumination device in said second state.

An image display apparatus for displaying an image recorded on a film, comprising:

• a) a spatial light modulation device which has a liquid crystal layer sandwiched between two polarization plates, and can maintain a recorded image in a non-energization state;
• b) an illumination device for illuminating said spatial light modulation device with light;
• c) a discrimination circuit for discriminating if said film is a negative or positive film;
• and
• d) means for inverting only an image recorded on said negative film by changing a direction of polarization of one of said two polarization plates in correspondence with an output from said discrimination circuit.

An image display device, wherein:

• an image on a film is recorded onto a spatial light modulation device,
• said spatial light modulation device is illuminated for an inspection of the image,
• an illumination device is provided to illuminate said spatial light modulation device through said film to record the image on said film onto said spatial light modulation device, and
• said illumination device illuminates said spatial light modulation device through said film with a light projected in a direction same as a light used when said spatial light modulation device is illuminated for the inspection of the image.
