Abstract: A color image pickup and display device that can be simply structured and provided at a low price. A lighting source irradiates lights of primary colors in a manner capable of being switched in a predetermined sequence. Monochrome solid-state image sensors are used as image pickup means, while a backlight type monochrome LCD element is used as a display of a display device. The LCD element can switch the color of backlight to the same color as that of the lighting source synchronously with the switching of color thereof. Thus, the backlight can emit light of the same color as that of the light emitted by the lighting source when the picture signals outputted by the sensors in response to the image observed by the light of the lighting source are displayed by the LCD element.

Abstract: A photographing and recording system including an electronic instrument with a photographing function, has a transmitter, a receiver, a sound data processor, an imaging device, an image data processor, and an image and sound recorder. The transmitter has a microphone provided for an object, and sends sound signals obtained by the microphone. The receiver receives the wireless sound signals sent from the transmitter. The sound data processor generates sound data on the basis of the sound signals. The imaging device produces image-pixel signals corresponding to an object image. The image data processor generates image data on the basis of the image-pixel signals. The image and sound recorder records the image data and the sound data in a memory while relating the image data and the sound data to each other, such that the sound data is read in accordance with the reading of the image data.
