Abstract
A characteristic detecting unit detects characteristics of a digital imaged signal at every phase shift interval set in advance. A timing adjustment unit gives a phase adjustment instruction of a pulse so as to converge to an imaging phase in the digital imaged signal at which the characteristics are a predetermined value or within a predetermined range. A shift interval switching unit switches the phase shift interval according to photographing conditions of an imaging element.
Claims18
A phase adjusting device for adjusting a phase of a pulse used in imaging of an analog imaged signal based on a digital imaged signal obtained by converting the analog imaged signal obtained by an imaging element to a digital value for every pixel, the phase adjusting device comprising:
- a characteristic detecting unit for detecting characteristics of the digital imaged signal at every phase shift interval set in advance;
- a timing adjustment unit for giving a phase adjustment instruction of the pulse so as to converge to an imaging phase in the digital imaged signal at which the characteristics are at a predetermined value or within a predetermined range;
- and
- a shift interval switching unit for switching the phase shift interval according to photographing conditions of the imaging element.
A phase adjusting method for adjusting a phase of a pulse used in imaging;
- the method comprising the steps of:
- detecting a first imaging phase at which characteristic of an image signal imaged using the pulse of each phase becomes a first predetermined value or within or above a first predetermined range while sequentially shifting the phase of the pulse at a rough adjustment phase shift interval set in advance;
- and
- setting a second imaging phase at which the characteristic of the image signal imaged using the pulse of each phase becomes a second predetermined value or within a second predetermined range as an optimum phase while sequentially shifting the phase of the pulse at a fine adjustment phase shift interval smaller than the rough adjustment phase shift interval.
