Abstract
The image pickup apparatus includes a finder optical system, a measuring part performing measurement relating to an object field image, a liquid crystal display element displaying in-finder information to be observed as an image superimposed on the object field image, and a temperature detector detecting temperature. A controller starts non-display control for causing the display element to change from a display state to a non-display state at a non-display control timing before start of the measurement, and starts display control for causing the display element to change from the non-display state to the display state at a display control timing before end of the measurement. The controller makes at least one of the non-display timing and the display timing earlier when a detected temperature acquired from the temperature detector is lower than a predetermined temperature as compared with when the detected temperature is higher than the predetermined temperature.
