RAMP WAVE OUTPUT CIRCUIT, ANALOG/DIGITAL CONVERSION CIRCUIT, AND CAMERA |
摘要 |
<p>A ramp wave output circuit includes a ramp wave generation circuit (1) which generates a ramp wave and a low-pass filter (2) having a variable cut-off frequency for receiving the ramp wave. The low-pass filter (2) operates with a first cut-off frequency for a predetermined time from the reception of the ramp wave and operates with a second cut-off frequency greater than the first cut-off frequency after a predetermined time has elapsed.</p> |
