Abstract
In image processing apparatus, a sample hold unit samples and holds an output signal of the image sensor. A timing signal generating circuit generates a sampling clock to specify a sampling timing of the sample hold unit. A controller sets a phase of the sampling clock to the timing signal generating circuit. In an adjustment process that adjusts the phase of the sampling clock, the controller (a) causes the image sensor to scan a reference board, (b) sets predetermined plural phases to the timing signal generating circuit in turn, (c) calculates average values of image data obtained correspondingly to the plural phases and calculates a value of a parameter that indicates a fluctuation width of the average values, and (d) sets the phase of the sampling clock as a phase corresponding to the smallest value of the parameter.
