摘要： A method and apparatus within a television receiver for electronically aligning signals within the receiver by controlling support circuitry for an IF module. A control voltage source (DAC 114) controls both video alignment and picture IF (PIF) mute functions. The DAC is coupled to a video level control circuit (112) within the video amplifier circuitry of the television receiver. The control signal controls both the video level as well as a PIF mute circuit (116).

摘要： PROBLEM TO BE SOLVED: To provide an imaging device which has a function of easily confirming an adjustment result based on a vector waveform when an automatic adjustment function such as a white balance is used. SOLUTION: The imaging device has a waveform generator 3 for generating a vector waveform signal from a video signal in response to a depression of a switch 6 as a switch for automatically adjusting a white balance or the like and for outputting the generated vector waveform signal for a constant period of time. The imaging device also has a combiner 4 for superimposing a video signal on a vector waveform signal and for displaying the superimposed signal on a display 5. Since the vector waveform of the video signal is displayed on the display 5 for the constant time to be superimposed on the video, a result of adjusting the white balance or the like can be easily confirmed without involving another operation. Further, since the vector waveform automatically disappears after the lapse of a predetermined time period, the user can take an image without being disturbed by the vector waveform.

摘要翻译：要解决的问题：提供一种成像装置，其具有在使用诸如白平衡的自动调整功能时基于矢量波形容易地确认调节结果的功能。解决方案：成像装置具有波形发生器3，用于响应于按钮开关6产生来自视频信号的矢量波形信号，作为用于自动调整白平衡等的开关，并且用于输出所生成的矢量波形信号持续一段时间。成像装置还具有用于将视频信号叠加在矢量波形信号上并用于在显示器5上显示叠加信号的组合器4.由于视频信号的矢量波形被显示在显示器5上以恒定的时间被叠加在视频中，可以容易地确认调整白平衡的结果，而不涉及另一操作。此外，由于矢量波形在经过预定时间段之后自动消失，所以用户可以拍摄图像而不被矢量波形干扰。版权所有（C）2009，JPO＆INPIT

CONSTITUTION:A base circuit of an input transistor (TR) Q1 is provided with a buffer amplifier comprising TRs Q3, Q4, resistors R1, R2, R3 and a current source I2. Further, the TRQ1 is controlled for the conduction with a potential at a connecting point B between the resistor R3 and the TRQ4, and the conduction of the TRQ4 is controlled with a potential at a connecting point C between the TRQ1 and the current source I1. The connecting point B and a power supply VCC is connected with the TRQ5 and the conduction is set with a bias source V1, the connecting point C and the power supply VCC is connected with a TRQ2, and the conduction is set with a potential V1 in common with the TRQ5 and an output signal is obtained from the connecting point C. Thus, the output impedance of the TRQ1 is set smaller in comparison with an AC resistor of the TRQ2 side, allowing to make the change in the slow conductiv resistance of the TRQ1, T2 steep.

摘要： PURPOSE:To speed up response, to eliminate sagging, and to set a clamp level on the basis of digital data by sampling and holding the output digital data of an A/D converter when a sampling pulse is inputted, performing D/A conversion, and calculating the difference between the D/A-converted signal and an input signal and inputting the difference to the A/D converter again. CONSTITUTION:A TV signal is A/D-converted and data on its pedestal level is latched by a sample holding circuit 3. This data and the data from a clamp level setting circuit 4 are supplied to a subtracting circuit 5 to obtain their difference, which is D/A-converted. The resulting signal is amplified and inputted to a subtracting circuit 1 through a filter circuit 8 to subtract from an input signal, generating a clamped output. Consequently, the response to the input signal is speeded up, sagging is eliminated, and the clamp level is set on the basis of the digital data, so that the output data of the A/D converter is stabilized against drift.

摘要： PURPOSE:To stabilize the black level of a picture image, by detecting a black peak value of an image signal immediately before impressing to a CRT and by regenerating the back level in DC. CONSTITUTION:A signal processing section 4 switches corresponding to a blanking pulse PB input from a control terminal and putputs a constant-voltage B1 while blanking, and in the other period, outputs an image signal S. This output is fed to a peak clamp circuit 7 through a contrast amplifier 6 then, is output to terminal 10 through a driving circuit 9. If the value of constant-voltage B1 is set to the specified value between a white peak value level and a pedestal level, the lowest output signal of the signal treatment section 4 becomes voltage B1 in case no level lower than the voltage B1 exists in the image signal S. As this lowest level is output keeping, the voltage B2 of the peak clamp circuit 7 the black level is held to a constant value.

摘要： Provided is a technique capable of correcting unique shading characteristics of a single-eye stereoscopic imaging device. A focal length is acquired (Step S11). A one-dimensional correction table corresponding to the focal length is acquired from a plurality of stored one-dimensional correction tables (Steps S12, S13, S14, .). Shading correction is performed using the acquired one-dimensional correction table (Step S15). An arbitrary pixel is selected from main pixels, a correction value corresponding to the position of the selected pixel is read from the acquired one-dimensional correction table for the main pixel, and shading correction is performed for the basis of the correction value and the value of the arbitrary pixel. This process is performed for all of the main pixels and the sub-pixels. A two-dimensional SD correction unit 67B performs normal shading correction for the data subjected to the shading correction (Step S15) using a two-dimensional correction table (Step S16).

摘要： An imaging apparatus with an automatic adjustment function, such as a white balance adjustment function, enables a result of such adjustment to be checked easily using a vector display. A waveform generation unit 3 generates a vector signal from a video signal in response to an operation to push a switch unit 6 for automatic adjustment of white balance etc., and outputs the vector signal for a predetermined period. A synthesized signal generation unit 4 combines (superimposes) the video signal with (on) the vector signal and displays the synthesized signal on a display unit 5. A vector display superimposed on a video is performed on the display unit 5 for the predetermined period after the switch is pushed. This enables an adjustment result of white balance etc. to be checked easily without requiring other operations. The vector display is stopped automatically after the predetermined period, and thus does not disturb an imaging operation.
