PROJECTION DEVICE, IMAGE CORRECTION METHOD, AND COMPUTER-READABLE RECORDING MEDIUM

摘要

A projection device converts input image data into light and includes a correction control unit that calculates a correction amount used for eliminating a geometric distortion occurring in a projection image according to a projection direction based on a projection angle and a view angle and determines a cut out range including also an area other than an area of the image data after the geometric distortion correction estimated according to the correction amount, and a correction unit that generates cut out image data acquired by cutting out an area of the cut out range from the input image data and performs a geometric distortion correction for the cut out image data based on the correction amount.

1. A projection device comprising:
a projection unit that converts input image data into light and projects a converted image as a projection image onto a projection face with a predetermined view angle; a correction control unit that calculates a correction amount used for eliminating a geometric distortion occurring in the projection image according to a projection direction and determines a cut out range including also an area other than an area of the image data after the geometric distortion correction estimated according to the correction amount based on the correction amount; and a correction unit that generates cut out image data acquired by cutting out an area of the cut out range from the input image data and performs a geometric distortion correction for the cut out image data based on the correction amount.
