Digital camera cursor control by sensing finger position on lens cap

A digital camera comprising:

• an array of photosensors;
• a lens;
• and
• a cap adapted to cover the lens, the cap having an interior side and an exterior side, the interior side being viewable by the array of photosensors when the cap is covering the lens, the interior side having a first color when no pressure is placed onto the exterior side, wherein pressure on the exterior side causes an area of the interior side to change to a second color, the second color not equal to the first color.

A method of controlling position of a cursor on a display on a camera, the method comprising the following steps:

• pressing onto an exterior surface of a lens cap, thereby causing an area in the interior of the lens cap to change reflectance;
• imaging, by an array of photosensors, the interior of the lens cap;
• and
• moving the cursor to a position on the display that corresponds to the position, within the image of the interior of the lens cap, of the area having a changed reflectance.

• imaging, by an array of photosensors, the interior of the lens cap;
• and
• moving the cursor to a position on the display that corresponds to the position, within the image of the interior of the lens cap, of the area having a changed color.

A method of controlling motion of a cursor on a display on a camera, the method comprising the following steps:

• pressing onto an exterior surface of a lens cap, thereby causing an area in the interior of the lens cap to change reflectance;
• imaging, by an array of photosensors, the interior of the lens cap;
• and
• moving the cursor on the display in a direction that corresponds to a direction defined by a position, within the image of the interior of the lens cap, of the area having a changed reflectance, relative to a reference position.
