Abstract
In a portable information terminal to which an image projection function can be added, there is provided a technique for improving visibility of a projected image. The portable information terminal has a terminal body and an attachment attached to the terminal body and communicatively connected to the terminal body. The attachment has a projector for projecting an image based on image information obtained from the terminal body, and is configured such that a projection opening direction of the projector is variable with respect to the terminal body. The terminal body or the attachment identifies a state of the portable information terminal including a position of the attachment with respect to the terminal body. The terminal body or the attachment performs a projection control of the image based on the identified state. The projection control includes, for example, an image rotation control, an image shape control, or a projection angle control.
