摘要： PURPOSE:To improve the visual confirmation at a focal point in the case of the manual focus mode. CONSTITUTION:The video camera 1 is provided with a contour emphasis circuit 3 operating or stopping emphasis of a contour of a video signal outputted to an EVF 5 of the camera 1. The contour of the video signal displayed on the EVF is emphasized in interlocking with the changeover from the automatic focus mode to the manual focus mode. As a result, since the contour of the video signal of the EVF is adjusted in the MF, the visual confirmation performance of the focal point is improved and manual focusing is facilitated while monitoring an object by the EVF.

摘要： PURPOSE:To make it possible to hold the dispersion detection humidity by parallel connecting diodes within a dewing sensor and making the polarity of the diodes an anode at the side of a power source and a cathode at the other side. CONSTITUTION:Diodes 2 are parallel connected within a dewing sensor 1. The characteristic of the diodes 2 is made an anode at the side of the power source and a cathode at the side of the ground. Voltage is applied through a resistor R2 from the power source of a microprocessor 3. With the connection point between the resistor R2 and the dewing sensor 1 connected to an analog input terminal of the microprocessor 3, dewing detection is performed when the voltage at the time of dewing exceeds 0.45V. The diodes 2 may be contained in the sensor 1 or be connected to the side of the processor 3. Furthermore, when dewing is generated, voltage change is obtained in response to the inherent resistance change of the sensor 1 and the voltage does not exceed maximum applied voltage in accordance with the characteristic of the diodes 2 because it is clamped not much exceeding 0.6V to 0.7V.

摘要： PROBLEM TO BE SOLVED: To reduce power consumption while keeping sufficient luminance even when a signal is always inputted by lighting only a specified light source body by a light source control part and irradiating only the specified range of a liquid crystal display part. SOLUTION: The video signal of one horizontal scanning period is sampled at the rising of a clock pulse, and displayed on the liquid crystal display part 6 in synchronization with the timing of the sampling. When the sampling is performed with the clock pulse whose frequency is lowered to 1/2, a picture reduced to 1/2 in a horizontal direction is displayed. In order to reduce the longitudinal dimension of the picture, the horizontal scanning of the video signal is thinned. A write control pulse repeats a period when a pixel can be written and a period when it can not be written. The picture thinned on every horizontal scanning, that means, the picture whose longitudinal dimension is reduced to 1/2 is displayed on the picture display device. At such a time, by lighting light emitting diodes 1 to 3, the reduced picture 8 whose area is 1/ 4 of the original one is obtained.

摘要： PURPOSE:To add a simple circuit to monitor the state of a camera by selectively switching two chrominance signals to supply to a modulator or providing two modulators to arbitrarily obtain a carrier chrominance signal and a recording low frequency chrominance signal. CONSTITUTION:A camera image signal from an image pickup element 1 passes a preamplifier 2, a brightness amplifier 3, a luminance signal branches, one is made an FM signal by the FM modulator 4, thereafter, multiplexed by the chrominance signal, applied to a video head 5 and recorded. The other is added by the carrier chrominance signal and thereafter, outputted to a video signal terminal 11. The chrominance signal is branched by the output of the amplifier 2, the chrominance signal is demodulated in a demodulator 6 and inputted to the chrominance modulators 7, 8. In the modulator 8, a carrier applied to a chrominance sub-carrier input terminal 10 is modulated to output the carrier chrominance signal to an addition circuit with the luminance signal. In the modulator 7, the carrier applied to a chrominance low frequency carrier input terminal 9 is modulated, thereby, a low frequency converted chrominance signal output is outputted to the addition circuit with the FM converted luminance signal.

摘要： PURPOSE: To easily display and record lapse of time with respect to an optional video image. CONSTITUTION: An image pickup device 1 converts a light from an object into a video signal. An operation section 9 is made up of switches for timer indication on/off, start/stop/reset of a timer, and a timer mode and a signal in response to the switch selection is fed to a CPU 7 of a microcomputer section 6. The CPU 7 gives a control signal to a timer 8, the timer 8 gives time information to the CPU 7, which converts time information of the timer 8 into a character code signal to be displayed and it is fed to a character generator 5. The character generator 5 converts the character code signal into a video signal, which is fed to a synthesis means 2. The synthesis means 2 gives a signal synthesizing the video signal from the image pickup device 1 and the video signal from the character generator 5 to a recorder 4 and a display device 3, which displays the synthesized video signal and the recorder 4 records the synthesized video signal.
