Information processing apparatus and method of controlling the same

摘要

A distance measuring unit measures a distance from a picked-up image by an image pickup unit to a tip portion of a finger. When the measured distance is less than a reference distance, a CPU displays an identification mark at a position corresponding to the finger on a display image, and takes in a locus of the finger as a handwritten character/figure. When the measured distance is the reference distance or more, the CPU hides the identification mark, and does not take in the locus of the finger as the handwritten character/figure.

主权项

1. An information processing apparatus comprising a memory and at least one processor which function as:
a detection unit configured to detect a base point of an operation body that performs a gesture operation; a distance measuring unit configured to measure a distance between the information processing apparatus and the base point; a processing unit configured to perform processing according to a motion of the base point when the distance to the base point satisfies a distance condition of whether the distance is equal to or less than a reference distance or the distance is equal to or more than the reference distance; a display control unit configured to display a picked-up image on a display unit, the picked-up image being an image of the operation body picked up by an image pickup unit, and to perform control to display an identification mark at a position on the display unit corresponding to a position of the base point in the picked-up image displayed on the display unit when the distance to the base point satisfies the distance condition; and an image pickup control unit configured to control focus of the image pickup unit to focus the base point in the picked-up image at the reference distance and to control an aperture of the image pickup unit to make depth of field shallow with respect to the base point in the picked-up image.
