Document Type and Number:
Japanese Patent JP2019015876
Kind Code:
A
Abstract:
To provide a projection apparatus, an information processing apparatus, a control method and a program that can generate an image which can improve a dynamic range of a printed matter and superpose on the printed matter as a projection image even when there is no basic image information.SOLUTION: A projection apparatus 100 that projects a projection image on a projection area 50 including an image area of a printed matter 40 as an enhancement target area in a projection surface projects an entire black image test pattern on the projection area 50, acquires an imaged image IMG_B in which an imaging area 60 including the projection area 50 is imaged at its projection time, and projects an entire white image test pattern on the projection area 50 and acquires an imaged image IMG_W in which the imaging area 60 is imaged at its projection time. Then, the projection apparatus detects the projection area 50 from the imaged images IMG_B, IMG_W, and generates the projection image from an image in the detected projection area 50.SELECTED DRAWING: Figure 1
