A digital image converting apparatus with auto-correcting phase and a method thereof are provided. The digital image converting apparatus includes a phase controller, a delay locked loop (DLL), an analog-to-digital converter (ADC) and a position adjuster. The phase controller selects one of preset phases for outputting and continuously changes the output preset phase for controlling a clock signal produced by the delay locked loop. The ADC converts an analog display frame according to the adjusted clock signal. After all the preset phases are output in sequence, the phase controller can obtain an optimal phase for converting the display frame according to the smallest front porch of horizontal scan line and the smallest back porch of horizontal scan line of a digital display frame produced by the position adjuster.
