Abstract: To transfer an image signal from a electronic camera head to a personal computer, a PC card provides the interface between the camera head and the personal computer. The PC card is removably attached to the personal computer. As instructed by the personal computer, the PC card operates the camera head, sets its states, writes image data into a memory, reads the image data from the memory for transmission to the personal computer, generates control signals for a light refracting member, and informs the personal computer of the state of the camera head.

Abstract: An electronic still camera comprises a solid state image sensor for outputting a color picture signal corresponding an incident optical image, a signal processor for signal-processing the color picture signal from the solid state image sensor to produce a color still picture signal, a recorder for recording the color still picture signal produced by the signal processor, and a driver for moving at least one of the optical image and the solid state image sensor from an original position in a horizontal direction by a pixel pitch and in an oblique axial direction defined by horizontal and vertical lines extending respectively from the original position in the horizontal and vertical directions by half the pixel pitch.

Abstract: An electronic still camera includes an imaging device, a signal conversion device and a recording device. The imaging device includes a solid state imaging unit and optical color filters of different spectral characteristics arranged on the solid state imaging unit to convert photoelectrically converting the photographed image. The signal conversion device converts a signal from the imaging device into a luminance signal and two color difference signals. The recording device stores image information including the luminance signal and two color difference signals into a semiconductor memory card.

Abstract: An electronic still camera has a memory card, which is detachably provided, for recording photographed image data. The electronic still camera comprises a data compression unit for compressing image data to be recorded, a mode selection unit provided in association with the data compression unit to select a recording mode or compression mode, a buffer memory for once storing the image data compressed in the compression mode selected by the mode selection unit, and a determination unit for determining whether or not the image data stored in the buffer memory can be recorded on the recording medium. In the electronic still camera, when the image data was determined to be unrecordable by the determination unit, the image data stored in the memory is stored in the buffer memory till the recording medias assumes a recordable state.
