A phase control unit compares a phase of a display synchronization signal with a phase of a clock signal generated from a clock signal generated by an imaging clock generating unit, and controls oscillation of the imaging clock generating unit based on a result of the comparison. A drive signal generating unit generates a drive signal that drives a CMOS sensor based on a multiplication clock signal synchronized to the clock signal.

Electronic endoscopic apparatus

A CMOS sensor converts optical information into an electric signal, and outputs the converted electric signal as an image signal. An imaging clock generating unit generates an imaging clock acting as a source of a drive signal that drives the CMOS sensor. A drive signal generating unit generates an imaging synchronization signal and a drive signal based on the imaging clock. A display clock generating unit generates a display clock. A display synchronization signal generating unit generates a display synchronization signal based on the display clock. A phase comparing unit compares a phase of the imaging synchronization signal with a phase of the display clock, and controls oscillation of the display clock generating unit based on a result of the comparison.

A phase comparing unit compares a phase of an imaging-side synchronization signal with a phase of a display-side clock, and controls oscillation of a display-side clock generating unit based on a result of the comparison. A display timing adjusting unit receives a video signal output from an endoscope at a timing based on the imaging-side synchronization signal and adjusts a synchronization timing of the received video signal to a synchronization timing based on a display-side synchronization signal.

Electronic endoscope apparatus

An electronic endoscopic apparatus includes an endoscopic scope and an image processing processor. The endoscopic scope includes a solid-state imaging device, an imaging-side multiplying unit, and an imaging synchronization signal generating unit. The image processing processor includes a display clock generating unit, a monitor synchronization signal generating unit, a master imaging clock generating unit, a processor-side multiplying/dividing unit, a phase-comparison oscillation control unit, and a display timing adjustment unit.

An image pick-up unit inserted in the body picks up an image of the body, and transmits by radio the image to an extra-corporeal unit which is arranged outside the body. The image pick-up unit includes an image pick-up portion capturing an image, a data transmitting portion for transmitting the image obtained by the image pick-up portion to the extra-corporeal unit at a plurality of transmitting ratios, a characteristic amount detecting portion for detecting a predetermined amount of characteristics based on the image, and a determining portion for determining a valid image based on an output from the characteristic amount detecting portion. The data transmitting portion controls the data transmitting ratio in accordance with the determining result of the determining portion.

When a capsule is manufactured, a unique number such as a serial number is stored in non-volatile memory in the capsule. If the capsule is used with an external apparatus, the unique number is sent from the capsule to the external apparatus. The external apparatus relates each unique number with a capsule ID comprising a small number of bits in a management table formed in non-volatile memory and sends the capsule ID to the capsule, and the capsule ID with the small number of bits is set as an identifier in the capsule. In this manner, it is made unnecessary to provide a switch in the capsule for setting the identifier and it becomes possible to reduce and send the quantity of information sent as the identifier.

Capsule-type medical apparatus and a communication method for the capsule-type medical apparatus

Disclosed herein is an image compression apparatus including: a pre-processing means for effecting preprocessing to generate color imaging signals of locations spatially equivalent to the relative locations of pixels on a color filter from color imaging signals outputted from a solid-state imaging device having the color filter having a predetermined color arrangement disposed on a light receiving surface thereof and to convert the color imaging signals into a predetermined arrangement format color by color with keeping color space of the color filter so as to generate image data groups; and an image compression means containing a frequency converting section for treating an image data group arranged in the predetermined arrangement format as one unit to compute spatial frequency components within the one unit, a quantizing section for quantizing the spatial frequency components, and a coding section for coding the quantized spatial frequency components.
