摘要:
A digital electronic still camera has a detachably loaded memory cartridge. The cartridge includes control data representative of its status. The camera has an imaging unit for shooting an object field to produce an image signal. The image signal is connected into digital image data. A connector detachably connects the memory cartridge to a converter. A manual operation unit responsive to manual operation can generate a first instruction signal for preparation for shooting by the imaging unit and a second instruction signal to instruct shooting to be achieved by the imaging unit. A controller responsive to the manual operation unit for controlling the imaging unit and the signal converter to store the image data in the memory cartridge. When the first instruction signal from the operation unit is received, the controller reads out the control data from the memory cartridge. When the second instruction signal is received, the controller stores in the memory cartridge the image data from the signal converter depending upon the control data read out from the memory cartridge.

摘要:
A compression encoder uses an arbitrary normalization coefficient and a preset table to achieve a compression of image signal with a desired compression rate. Since the normalization coefficient and the table data are sent to an image signal decoding and reproducing apparatus together with the compressed image data, the reproducing apparatus can restore the original image from those data items. Furthermore, in the encoder, when an amplitude value of the data exceeds a predetermined value, an overflow sensor means the condition so as to produce normalized data in addition to the Huffman-encoded data. The reproducing apparatus achieves the image signal decoding and reproducing operations by use of the normalized data and the Huffman-encoded data. With these apparatuses, the picture quality can be prevented from being lowered due to an overflow in the encoding operation.

A single-legged chair comprising a support post and a seat mounted on the support post at a predetermined position thereof so as to constitute a leg portion by a lower part of the support post below the seat, the general plane of the seat lying at an angle of 70.degree. to 85.degree. with respect to the support post at least when the chair is in use. In use, the seat lies virtually horizontally as the leg portion stands on the ground or floor in an inclined posture.

A toner container includes a substantially tetrahedral toner-containing portion having an openable edge to discharge toner contained in the toner-containing portion, and a reference fold along which the toner container is foldable after the openable edge is opened. The reference fold extends from the openable edge and is provided on medians of two triangular faces of the toner-containing portion adjoining each other along the openable edge.

A fixing device includes a pair of fixing members opposing each other and a pressing lever that is rotatable around a shaft. The pressing lever can be moved either to a pressing position in which one of the fixing members is pressed against the other fixing member, or to a pressure releasing position in which the one of the fixing member is separated from the other fixing member. When the pressing lever moves between the pressing position and the pressure releasing position, a first control unit located near an end of the pressing lever controls displacement of the end.
