Abstract
In a display apparatus of a camera according to this invention, an imaging device repeatedly images an object to be photographed and generates a two-dimensional luminance signal. A one-dimensional pattern signal is repeatedly generated from the two-dimensional luminance signal for at least one of inside or outside the imaging device. Each time a new pattern signal is generated, the immediately preceding pattern signal is stored in a frame memory. After the immediately preceding pattern signal is stored in the frame memory, a CPU performs a correlation arithmetic operation between a new pattern signal and the immediately preceding pattern signal stored in the frame memory. The CPU detects a moving amount of the object to be photographed according to the movement of the camera during the repetition time period, and performs the correlation arithmetic operation each time the frame memory stores an immediately preceding pattern signal. In accordance with the moving amount arithmetically operated by the CPU, the moving amount of the object to be photographed is displayed on a display unit in a finder using the width of a photographing picture as a basic unit.
