Abstract
An image pickup apparatus includes a detection unit configured to detect proximity of an object to a viewfinder, a line-of-sight detector configured to detect as line-of-sight information, using an eyeball image of a user who peers through the viewfinder, a position that the user gazes at in a display unit disposed inside the viewfinder, and a processor configured to determine whether or not to prohibit the display unit from being set to a non-display state using a feature in the eyeball image, in a case where the line-of-sight information is not detected, and not to set the display unit to the non-display state, in a case where the processor determines that the display unit is prohibited from being set to the non-display state.
Claims5
An image pickup apparatus comprising:
- a line-of-sight detector configured to acquire an eyeball image of a user who peers through the viewfinder to detect a line-of-sight of the user gazing at in a display unit disposed inside the viewfinder based on the eyeball image;
- and
- a processor configured to
- perform a first determination process to determine whether or not the line-of-sight is detected by the line-of-sight detector,
- perform a second determination process to determine whether or not to prohibit setting the display unit to a non-display state based on whether a radial bright spot is present in an eyeball range, and an edge area of glasses or sunglasses, which is an area formed by a line with a predetermined thickness, is present in the eyeball image, after the first determination process, in a case where the line of sight is not detected in the first determination process,
- determine to prohibit setting the display unit to the non-display state, in a case where the radial bright spot is present in the second determination process, and the edge area of the glasses or sunglasses is present in the second determination process, and
- control the display unit not set to the non-display state according to a determination to prohibit setting the display unit to the non-display state by the second determination process.
