Abstract: Methods and apparatus are provided for computing focus information prior to scanning digital microscope slides with a line scan camera. The methods include a point-focus procedure that works by moving the slide to the desired measurement location, moving the objective lens through a predefined set of height values, acquiring imagery data at each height, and determining the height of maximum contrast. The methods also include a ribbon-focus procedure whereby imagery data are acquired continuously, while the slide and objective lens are in motion. Both methods may be applied with either a static or a dynamic implementation.

Abstract: A scan-beam detection signal Hsync provided by horizontal synchronous sensors 60A, 60B is inputted to a drive signal controlling section 10Y as a drive period signal related to a drive period of a deflective mirror. The drive signal controlling section 10Y controls a drive signal Sd such as to establish a predetermined relationship between a phase of a reference signal Sr and a phase of the horizontal synchronous signal Hsync, whereby a deflector 65 is allowed to operate in synchronism with the reference signal Sr. Therefore, a latent-image forming position with respect to a sub-scan direction Y is adjusted by way of the phase adjustment between the reference signal Sr and the horizontal synchronous signal Hsync, so that a linear latent image is prevented from deviating with respect to the sub-scan direction Y.

Abstract: A comparator compares a time interval between a first synchronization signal and a second synchronization signal with a target value, and outputs an error therebetween. A frequency calculator calculates a set value of a pixel clock frequency based on the error output from the comparator, and outputs a frequency specification signal for specifying a pixel clock frequency according to the calculated set value. A frequency divider divides a high frequency clock generated by a high frequency clock generator by a frequency division ratio based on the frequency specification signal output from the frequency calculator, and generates the pixel clock.
