Abstract: An exposure control device of a still-video camera has a CCD and a photoreceptor element for sensing a photometry value of an object. First, the camera is aimed at the main object in such a manner that the main object is positioned in the center of the frame, and a first photometry value is obtained. Then, the aim of the camera is changed so that the main object is offset from the center of the frame, and a second photometry value is obtained. A provisional exposure is carried out in accordance with an aperture value and an electric charge accumulating time which are obtained based on the second photometry value, and thus an exposure value is obtained. A ratio of the proper exposure value and the provisional exposure value is obtained. A normal exposure is carried out in accordance with the aperture value and a normal electric charge accumulating time TT=T.times.(E0/E2).times.

Abstract: A luminance signal generating device having two CCDs on which complementary color filters are provided. Each color filter includes a matrix arrangement in which color filter elements for passing magenta, green, yellow and cyan light are arranged in a regular manner. If a first field is read from the CCDs, magenta (Mg) and Green (G) pixel signals of odd-numbered rows are read from the first CCD, and yellow (Ye) and cyan (Cy) pixel signals of even-numbered rows are read from the second CCD. If a second field is read from the CCDs, yellow (Ye) and cyan (Cy) pixel signals of even-numbered rows are read from the first CCD, and magenta (Mg) and green (G) pixel signals of odd-numbered rows are read from the second CCD. Four pixel signals (Mg, G, Ye, Cy) from optically adjacent pixels are added to each other to obtain a luminance signal.

Abstract: A pixel signal generating device is provided with a color filter having a matrix arrangement, in which color filter elements for passing magenta light, green light, yellow light and cyan light are arranged in a regular manner. A first exposure is performed without radiating an electronic flash, and Ye- and Cy-signals are inputted into a second image memory. A second exposure is performed while radiating the electronic flash, and Mg- and G-signals are inputted into a first image memory. Without discharging electric charges accumulated on the CCD, a third exposure is performed without radiating the electronic flash, and Ye- and Cy-signals are generated. The Ye- and Cy-signals obtained by the first exposure and stored in the second image memory are subtracted from the Ye- and Cy-signals of the second and third exposure to form one image.

The apparatus includes a first color temperature detector for detecting a color temperature of the strobe light after being reflected from an object, a second color temperature detector for detecting a color temperature of ambient light reflected from the object, and a color temperature controller. The color temperature controller controls the color temperature of the strobe light detected by the first color temperature detector, so that the color temperature of the strobe light incident upon the object to be photographed is substantially identical to the color temperature of the ambient light detected by the second color temperature detector.

Abstract: A distance measuring device has an infrared light-emitting diode by which an infrared light is emitted towards a subject, and first and second linear line sensors on which an image corresponding to light reflected from the subject is formed. The first and second linear line sensors are disposed adjacently and in parallel to each other, and offset by an amount corresponding to half of the predetermined A/D converting step. Analog distance data outputted from the linear line sensors are converted to digital distance data using the predetermined A/D converting step, and then, the digital distance data are added together to obtain a subject distance with a high accuracy.

Abstract: A mode changing device for a camera employing a minimum number of actuating members to permit a user to change an operating mode and/or setting of the camera. A mode actuating member and a selector switch, used in conjunction with an LCD panel that indicates the mode and setting that has been selected by the user, permits the user to easily select and/or adjust the features of the camera, such as a photographing mode, a playback mode, an exposure mode, a white balance mode, a copy/monitor mode and a time/date mode. When the mode changing device is applied to a still video camera having a playback function, a change-over switch automatically changes the operating mode of the camera from a record mode to a playback mode when a monitoring adapter is connected to the camera, further reducing the number of actuating members that are needed to control the camera.

Abstract: A record and play-back system for a still video device, in which a picture signal and an audio signal associated therewith are recordable on a first track and a second track of a recording medium; a first code signal and a second code signal are recorded together with the associated picture signal and the associated audio signal to discriminate that the respective picture signal and audio signal are recorded together with the corresponding audio signal or the picture signal. The second track is played back when the first code signal is recorded on the first track upon play-back of the first track. The audio signal can be post-recorded on the second track when no signal is recorded on the second track.

Abstract: A zoom lens camera has a zoom switch which is operated to drive a zoom lens. A photometric device measures light from an object to drive an aperture in accordance with the result of the photometry that is conducted by the photometric device. The driving of the zoom lens and the driving of the aperture are controlled so that the driving of the zoom lens is temporarily suspended when an instruction is given to drive the aperture. After the aperture has been driven in accordance with the photometry result, the driving of the zoom lens is resumed.
