A signal processing apparatus relays communication of control signals between a controller and a plurality of processing modules, and includes: a communication device configured to perform communication of the control signals with the plurality of processing modules; a plurality of first storages provided respectively to correspond to the plurality of processing modules, the plurality of first storages being configured to store the control signals written by the controller; a second storage configured to store: address information indicating each communication address assigned to each of the plurality of processing modules; and correspondence information indicating correspondence relationships between the plurality of first storages and a plurality of module-side storages respectively included in the plurality of processing modules; and a synchronization processor configured to synchronize the plurality of first storages with the plurality of corresponding module-side storages via the communication device based on the address information and the correspondence information.

Signal processing apparatus

A processor including hardware and performing control in accordance with an input signal is configured to: read, after the processor is booted, firmware information including an encrypted authentication file and an execution program to be executed by the processor; decrypt the encrypted authentication file with reference to the read encrypted authentication file and key information for decrypting the encrypted authentication file; execute the execution program in the processor when the encrypted authentication file is decrypted; and stop the execution of the execution program in the processor when the decryption of the encrypted authentication file fails.

Processor, control device, and computer readable recording medium

To reduce more load related to the correction of deformation of an observation image that is caused by an error between a plurality of imaging sections. A medical stereoscopic observation device includes: an acquisition section configured to acquire, from an imaging unit including a first imaging section configured to capture a left-eye image and a second imaging section configured to capture a right-eye image, correction data for correcting an error related to capturing of an image between the first imaging section and the second imaging section, the imaging unit being rotatably held by a support section; and a correction section configured to correct a difference of parallax between the left-eye image and the right-eye image on a basis of the correction data, using a position corresponding to a rotation axis of the imaging unit as a reference position.

Medical stereoscopic observation device, medical stereoscopic observation method, and program

An interface modulerelays control signal communication between a main CPUand a light source control CPUand between the main CPUand a camera head CPU. The interface moduleincludes an FPGAhaving CPU I/Fstothat correspond to communication schemes of CPUs, and, respectively, and first and second storage units() and(). The FPGArelays a control signal between the main CPUand the light source control CPUand between the main CPUand the camera head CPU, while temporarily storing the control signal in the first and the second storage units() and(). Moreover, a first communication timing and second and third communication timings are set at timings shifted from one another.

Relay device and medical device

A light-incorporated video camera incorporating a video light integrally in a video camera, includes: a video light input switch for instructing turn-on of the video light; and a timer; wherein the video light turned on by instruction from the video light input switch is automatically turned off after the elapse of a time set on the timer. If a switch key of the video camera is operated before the time set on the timer expires, the timer is initialized to continue the turn-on state of the video light. In this video camera, preferably, the switch key is a record/stop switch key of the video camera, the video light is a tungsten halogen lamp, and the timer is a five-minute timer.
