Patent ID: 7932940

Claim:
A viewfinder configured to display a captured image, comprising: hue selection means for enabling a user to select an edge enhancement correction target hue; edge correction signal generating means for generating a peaking signal from three primary color signals generated from an input video signal; signal adding means for adding the peaking signal generated by the edge correction signal generating means to each of the three primary color signals generated from the input video signal; and driving signal generating means for generating a driving signal for a display device from the three primary color signals to each of which the peaking signal has been added by the signal adding means, the edge correction signal generating means having: peaking signal extracting means for extracting peaking signals from the three primary color signals generated from the input video signal by detecting high-frequency components from the three primary color signals, weighting setting means for assigning weights to each of the peaking signals extracted from the three primary color signals by the peaking signal extracting means on the basis of the edge enhancement correction target hue selected by the user, peaking signal adding means for adding the weighted peaking signals from the weighting setting means together to generate the peaking signal corresponding to the edge enhancement correction target hue, highest-level peaking signal priority setting means for selecting a highest-level peaking signal from among the peaking signals extracted from the three primary color signals by the peaking signal extracting means, and outputting the selected highest-level peaking signal, and selecting means for selecting one of the peaking signal out from the highest-level peaking signal priority setting means and the peaking signal generated by the peaking signal adding means in accordance with a selection signal, in which when the selecting means is operated to select the peaking signal out from the highest-level peaking signal priority setting means, the user does not need to select the edge enhancement correction target hue.
