An interactive video display system uses strobing light to allow easy and unencumbered interaction between a person and projected video images. A camera may be synchronized to the strobing light and the strobing light may be in an infrared spectral range. A processing system detects images of a human in the field of view of the camera and controls the display so that the projected video images are changed based on an interaction between the human and the projected video images. The system may project the video images on a surface around the person and may move the projected video images on the surface based on a movement of the person. The projected video images may include computer-generated characters and / or virtual objects that react to the movement of a person.

A printer-built-in image-sensing apparatus including a camera which performs image sensing with film exposure, and a printer which prints an image sensed by the camera. After a shutter button has been pressed and image sensing with strobe light emission has been performed, if printing is instructed by pressing of a print button, then electric charging a capacitor of a strobe circuit is made after the completion of the print operation. Otherwise, the charging of the capacitor is started immediately after the image sensing. In this case, even if printing is instructed during the electric charge, printing is started after completion of the electric charge. Thus, electric consumption upon print operation can be reduced and fluctuation of voltage can be suppressed.

When the mode is set to a strobe consecutive shooting mode, an imaging apparatus sets the mode to a pixel addition drive mode for reading out image data using pixel addition drive, performs metering operation using preliminary flashing and calculates an appropriate amount of flashing on the basis of the metering operation.
