A camera which can place an antenna for performing wireless communication at an ideal position without providing a complicated mechanism is disclosed. The camera has a camera body, a movable portion which can be projected from and retracted in the camera body to take an image or observe an image, and an antenna which is formed in the movable portion to perform wireless communication.

An image pickup apparatus is provided which can obtain a high image quality by using a camera with a conventional field read type DSP. The image pickup apparatus has an image pickup element having a plurality of color filters disposed in a predetermined layout at respective pixel positions, a calculating and processing unit for performing calculation and processing by using two sets of adjacent pixel data in the vertical direction, at each line of image data generated by the image pickup element, and a luminance signal generating unit for generating a luminance signal by using an output of the calculating and processing unit.

A head-position controlling device includes a head moving mechanism for causing a head to move with respect to a recording track on a recording medium; a detecting circuit for detecting an amplitude of a reproduced signal which is reproduced from the recording track on the recording medium by the head; and a controlling circuit for controlling the head moving mechanism on the basis of an output of the detecting circuit. If so that if the amplitude of the reproduced signal is greater than a predetermined level, the head is made to move in units of a first moving amount to detect a position where the amplitude of the reproduced signal is a maximum, and if the amplitude of the reproduced signal is less than the predetermined level, the head is made to move in units of a second moving amount greater than the first moving amount. If the amplitude of the reproduced signal becomes greater than the predetermined level, the moving amount of the head is switched to the first moving amount.
