Image display apparatus, image pickup apparatus, computer readable recording medium for recording processing program to control image display apparatus, and method of controlling image display apparatus
First Claim
1. An image display apparatus comprising:
- a pixel shift extension display section which includes a display element, a pixel shift element which enables a high definition display with a number of pixels greater than a number of pixels of the display element by cyclically varying a spatial position of an image to be displayed on the display element, and an extension optical system which extends the image displayed on the display element through the pixel shift element;
a display controller which controls the pixel shift extension display section in one of a plurality of display modes, each having a different pixel shift operation and a different power consumption;
a power source structured to receive power at least from a battery;
a power source state determination section which determines a remaining level of the battery; and
a mode setting unit which sets the display mode controlled by the display controller in such a way that the display mode, in a case in which a determination result of the power source state determination section shows that a remaining level of the battery is relatively low, is a display mode with power consumption lower than that of the display mode in a case in which the determination result shows that the remaining level of the battery is relatively high.

Abstract
Image display apparatus includes an EVF-display section which allows the pixel shift element to cyclically vary a spatial position of images displayed on the display element for a high definition display with more pixels compared with the display element by allowing extended image observation via an eye-optical system, an EVF-display control section which controls the EVF-display section in such modes as a four-point pixel shift, a two-point pixel shift, a partial pixel shift, a lowpass filter (LPF), and the pixel shift OFF, each with different power consumption, a power source, a power source state determination section for determining whether the power source is driven by the battery or the external power source, and the remaining battery level, and a pixel shift display determination section for setting the display mode with the lower power consumption in the order of the low-remaining battery level, the high-remaining battery level, and the externally-driven power source.
