Abstract:
1. An image pickup apparatus comprising: A finder optical system configured to enable observation of an object field image formed on a focusing screen by light from an image taking optical system; a measuring part configured to perform measurement relating to the object field image by using the light entering thereinto from the focusing screen through at least part of the finder optical system; a liquid crystal display element disposed in an optical path passing through the focusing screen toward the finder optical system, and configured to display in-finder information to be observed as an image superimposed on the object field image through the finder optical system; a controller configured to start non-display control for causing the liquid crystal display element to change from a display state to a non-display state at a non-display control timing before start of the measurement performed by the measuring part, and configured to start display control for causing the liquid crystal display element to change from the non-display state to the display state at a display control timing before end of the measurement; and a temperature detector configured to detect temperature, wherein the controller is configured to make 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.
