In FIG. 1, reference numeral 1 denotes an image output apparatus as a whole, and a printing unit 3 prints a predetermined image on a lenticular sheet 2 having a lenticular lens 2A formed on one surface thereof. That is, in the image output device 1, the composite image signal S1 is sent to the image memory 6 via the interface unit 5 of the signal processing unit 4.

Here, in the image output device 1, as the composite image signal S1, an image picked up by a plurality of television cameras arranged in multiple directions is arranged in a stripe in one frame (Television Society of Japan). Magazine Vol.45, N
o.11, pp.1472-1474 "50-inch multi-view glassesless three-dimensional television projector").

The composite image signal S1 is formed by the procedure shown in FIG. That is, a plurality of television cameras 30A, 30B, 30C and 30D arranged in multiple directions.
From this, images 31A, 31B, 31C and 31D having parallax are obtained. Next, the pixels at the same position among these images 31A to 31D are displayed on the television cameras 30A to
By arranging according to the arrangement of 30D, the composite image 32
And the composite image 32 is input to the interface section 5 as a composite image signal S1.

The image output device 1 sequentially reads the composite image signal S1 once held in the image memory 6 by the memory controller 7 in the order necessary for the scanning direction of the print output and the signal processing by the signal processing circuit 8, and then continues. The signal is sent to the signal processing circuit 8. The signal processing circuit 8 applies R (red), G (green) and B to the composite image signal S1.
Color signals of (blue) are Y (yellow), M (magenta) and C
Color signal conversion for converting into a (cyan) color signal and gamma correction are performed. The output signal of the signal processing circuit 8 is supplied to the thermal head 10 of the printing unit 3 as a composite image signal S2 via the digital-analog conversion circuit 9. In this way, the image output device 1 outputs the composite image signal S1
The signal processing unit 4 converts the composite image signal S2 suitable for the input characteristics of the heat-sensitive head 10 and then supplies the composite image signal S2 to the heat-sensitive head 10 of the printing unit 3.

The signal processing unit 4 is adapted to execute such signal processing based on the control signal S3 sent from the system control unit 11. Further, the system control unit 11
Sends a control signal S4 to the motor drive circuit 12. The motor drive circuit 12 sends a drive signal S5 to the take-up reel motor 13 based on the control signal S4, and as a result, the take-up reel motor 13 is driven to send the ribbon wound around the take-up reel 14. 15 is wound on a take-up reel 18 while being supported by guides 16 and 17 on both sides of the thermal head 10.

Further, the system controller 11 sends a control signal S6 to the motor drive circuit 19, and the motor drive circuit 19 sends a drive signal S7 to the platen motor 20 based on the control signal S6. As a result, the platen motor 20

Thus, in the image output device 1, the dye applied to the ribbon 15 is thermally transferred to the lenticular sheet 2 by applying heat to the ribbon 15 by the thermal head 10 while feeding the lenticular sheet 2 and the ribbon 15 by a predetermined amount. It is done like this.

Here, the image output apparatus 1 has a position detecting section 22, and the position detecting section 22 detects the position of the lenticular sheet 2. That is, the position detecting unit 22 uses the back surface side of the lenticular sheet 2 (the surface on which the lenticular lens 2A is formed is located on the lenticular sheet 2).
After the light beam of the irradiation light generated from the light source 23 provided on the surface of the lenticular sheet 2 is narrowed by the slit 24, this light beam is collimated by the lens 25 and irradiated onto the lenticular sheet 2.

This irradiation light L1 is emitted by the lenticular lens 2A.

Is incident on the photo sensor 26 provided on the front surface side of the. At this time, the transmitted light L2 entering the photo sensor 26 has a maximum light amount when the center of the light receiving portion of the photo sensor 26 and the center of the unit lens of the lenticular lens 2A coincide with each other.

As a result, in the image output device 1, the position of the lenticular sheet 2 can be detected based on the amount of the transmitted light L2 entering the photo sensor 26, and the photo sensor 2 can be detected.
6 sends the detection result to the system control unit 11 as a detection signal S8. System control unit 1
1 is a control signal S for the signal processing unit 4, the motor drive circuit 12, and the motor drive circuit 19 based on the detection signal S8.
3, S4 and S6 are sent out. Further, in the image output apparatus 1, the photo sensor 26 and the thermal head 10 are positioned so that the distance between them is a predetermined value.
