What We Do

我們所做的事情

With so many suppliers involved in the design and production of cameras,do you really know what type of quality they’re delivering? Sure,they show you test results,but can you really trust them? That’s where Imatest comes in。 We offer independent and unbiased guidelines in order to help you measure the quality of the cameras in your products。

有如此多的供應商涉及相機的設計和生產供應鏈,您是否真的瞭解供應商交付的產品品質是好是壞? 當然有些供應商會給出生產測試結果,但這些資料是否有足夠的可信度? Imatest可以讓圖像品質標準準確可靠。我們提供獨立且公正的參考標準,可以幫助您檢測相機產品的品質。

Some companies attempt to create their own in-house testing software。 The result is typically an incomplete system that can have inconsistencies。 At Imatest,image quality testing is all we do。 We’re experts when it comes to testing so that you can focus your expertise on creating great products,rather than writing software。

有些公司嘗試自己開發圖像檢測軟體。但結果往往發現難以達到完備和很好的一致性。對於Imatest而言,我們專注於圖像品質檢測,這就是我們的全部工作。因此做為這個領域的專家,我們可以幫助您更好的解決圖像品質問題,而您則可以將精力集中在開發偉大的產品上,而非編寫圖像品質程式上。

SFRplus vs。 ISO Standards

SFRplus對比ISO標準測試卡

Developed by experts and used in a wide variety of imaging industries,the ISO requirements have good reason to be the standard。 However,technology is rapidly advancing and ISO standards are slow to adapt to ever-evolving specs and new camera capabilities。

ISO標準由ISO專家組開發,並且在圖像領域應用廣泛。但是當代技術的發展十分迅速,而ISO標準的制定則相對較緩慢,很大程度上滯後於新出現的技術要求和新相機的能力。

Imatest’s software solutions and SFRplus test charts build upon the ISO standards so that our customers have the most capable image quality testing available。 We’ve built upon what works and omitted aspects that don’t benefit objective camera quality testing。

Imatest軟體解決方案以及SFRplus測試圖卡基於ISO標準之上,並對其不適於客觀品質檢測的不足之處做出了許多改進,以適合於新的要求。
